How to install a plastic window sill with your own hands. Installation of a plastic window sill: technology and necessary tools. Installation of a window sill on a balcony

Almost any modern renovation involves the replacement of windows, and few of the developers come to mind to leave the old, painted oil paint wooden or asbestos-cement window sill. Many people are familiar with the situation when the “windowers” finished their work and left, and the new window sill was left alone to stand near the wall. What to do next? Looking for masters again?

The window sill is a must modern interior. At the same time, it performs not only a decorative function, not only serves as a stand for flowers and household appliances, but also actively participates in the processes of air exchange that occur near windows. Protecting the lower part of the window opening from possible condensation and mechanical damage, thermal insulation of one of the most problematic areas of the outer walls - this is the true, utilitarian purpose of a well-installed window sill.

How to choose a window sill

At the moment, it is not difficult to buy a window sill made of durable, dimensionally stable material, resistant to sunlight and temperature changes. There are many options on the market, each with its own pros and cons. However, the main problems of choice come down more to implementation issues. design solutions and wallet thickness.

Due to the low cost, from 55 rubles per linear meter, and good technical characteristics, PVC window sills are most widely used. They have similar properties to plastic windows, as they are made from the same UV-resistant, water-resistant materials. The multi-chamber structure with frequent bulkheads provides them with high compressive strength and excellent thermal insulation properties.

Light weight, ease of cutting and processing greatly facilitate the process of installing plastic window sills. It is not a problem to choose the color of the finished product, including wood and marble imitation. The color can be transferred both "in mass", for example, brown, and in the form of a film according to the RAL catalog. Most often, such window sills are made to match the window profile. The front surface of the PVC window sill has a matte texture or has a varnish coating. It is easy to find a plastic window sill that is suitable in size for almost any specific occasion. In large hardware stores, products with a thickness of 18-22 mm and a width of 100 to 600 mm are often available. The strips are 4 or 6 meters long, but, as a rule, you can order their cutting on the spot, or buy a window sill of any length. The main disadvantages of plastic window sills can be considered weak resistance to local damage: scratches, chips, breakdowns. They are practically unrepairable.

Window sills made of MDF and chipboard can be laminated upper layer, be covered with cork or wood veneer. At a low price, they perfectly imitate expensive materials, including a natural stone. Such products have good performance and thermal insulation properties. They are easy enough to cut and install.

If the protective coating of window sills made of MDF and chipboard is not damaged, then they are not exposed to moisture, do not warp or swell. Laminated window sills are difficult to scratch. Their cost per linear meter can range from 150 to 1200 rubles with a width of 30 cm.

Window sills made of coniferous and hardwood species are the best suited to wooden windows, have a very beautiful texture, visible under a transparent protective coating, but can also be dyed in any color. They are also a good thermal insulator.

Depending on the properties of the wood used, they have a certain degree of bending strength, resistance to scratches and dents, and they are also easy to repair. The thickness of window sills made of wood is most often about 40 mm. Among the shortcomings, one can note the need to ensure their waterproofing, which completely depends on the condition and quality of the protective and decorative coating, which requires periodic renewal. Prices for products made of oak, hornbeam, beech, cherry, ash can hardly be called affordable. A high-quality window sill made of massive pine will “pull” at least 1000 rubles per linear meter, larch - 1800, beech - 3000, oak - 5000.

Window sills made of natural stone - marble, granite or onyx, are perhaps the most expensive of all on the market (from 3,000 rubles per linear meter), but their classic beauty, sophistication and prestige leaves no one indifferent. The assets of such products include an expressive texture, a choice of color, size, shape, style of processing corners and edges. Stone window sills are not afraid of water and temperature changes, but to some extent they are prone to pollution due to the porosity of natural materials. Being quite fragile, natural stone products are well repaired. The heavy weight, as well as the complexity of processing, make their installation somewhat difficult. Window sills made of natural stone do not have thermal insulation properties.

Models of window sills made of artificial stone have operational advantages - this is resistance to chemical pollution, relatively low thermal conductivity. Trouble (in the low price category similar products) can cause scratches on the front surface and its fading. Of course, they are cheaper than analogues made from natural materials.

How to determine the required dimensions of the window sill

In order for the window sill to serve for a long time, be convenient and functional, it must not only be correctly installed, but also correctly calculate its dimensions. In some cases, it makes sense to manufacture the window sill in the factory according to the exact dimensions. This problem is especially serious when working with stone, since it is quite difficult to process, and it’s very good if you don’t need to adjust anything locally. Window sills made of MDF and chipboard can be ordered with a fully processed edge, which also does not need to be cut off, as it reliably protects the product from moisture.

The length of the finished product must be greater than the width of the window so that the window sill enters the walls. Usually, from 30 to 50 mm are released for the line of vertical slopes on each side. For example, if the width of the window is 1000 mm, then it would be logical to order the window sill 100 mm more, 20 of which will go to the light turn of the slopes, 80 - to the side outlets (40 mm each). In the area of \u200b\u200bthe balcony block, the window sill cuts into the wall with one side, and near the door it should hang a little, about 10 mm, over a short vertical slope.

The width of the window sill is mainly determined by the depth of the window opening. As a rule, the overhang of the window sill is made about 30-50 mm from the wall. This size is explained by the fact that a window sill that is too wide can prevent the free circulation of warm air coming from heating radiators, which can lead to the formation of condensate on the surface of double-glazed windows and side slopes. With a large overhang, the bending strength of the structure is significantly reduced.

To correctly determine the desired width of the window sill, it is necessary to perform the main finishing of the outer wall - plaster, drywall. It will be enough to have installed beacons or a metal frame. Measurements are made with a tape measure from the window to a cord stretched in the plane of the wall or a rule installed across the opening.

Attention! It should be noted that the window sill of about 10 mm enters under the frame, resting against the mounting plate of the plastic window or a quarter of the wooden profile.

It is especially difficult to measure non-standard window sills, such as on rounded walls, bay windows, kitchen countertop window sills. Sometimes the window is deployed in the opening, then if you want to have an equally protruding window sill cornice, its width will have to be made uneven. In all these cases, for the manufacture of templates and patterns, we recommend inviting specialists from the organization in which you will order them. The most accurate, flawless products are obtained from measurements taken with surveying equipment, such as a total station. A tape measure and a cardboard sheet do not always help out.

The main principle is simple: "measure seven times - order once."

When to install a window sill

If you decide to simply change the windows while maintaining the entire interior decoration of the premises, then there is nothing special to wait for - you can proceed immediately after the mounting foam dries.

But in the case of a major overhaul, the matter is a little more complicated. The reason for this is the vulnerability of the surfaces of the prematurely expensive product installed. In the process of carrying out extensive repair and construction work, when there are a large number of employees at the facility, guests from contractors (air conditioners, security system installers, installers stretch ceiling, furniture assemblers ...), it is extremely difficult to keep the window sill safe and sound. A flat horizontal surface, like a magnet, pulls you to place a tool on it, small, and not very, building material, put a cup of coffee, step with your foot to reach the high ceiling. As a result - the replacement of the window sill and the alteration of the slopes due to "no one knows where" appeared scratches, dents, chips, persistent chemical stains.

Many practicing builders have come to the conclusion that the installation of a window sill must be done at the very last moment, just before finishing. Naturally, by this moment the whole range of preparatory work must be completed, including the installation and even puttying of walls and slopes.

How to prepare a place for installing a window sill

Depending on the type of product, its material and thickness, as well as on the chosen method of fastening, we will prepare the base. First of all, it is necessary to remove all loose, protruding elements of the wall on which the window sill will rest, these are loose bricks, rusty plaster, installation wedges, fasteners, and embedded parts. If during dismantling work formed through holes on the street, or in enclosing structures, it is recommended to foam them.

You also need to prepare strobes in the wall for the window sill to enter, here you can not do without the use of a small grinder and a puncher. If the slopes are sheathed with drywall or plastered, then their plane must be interrupted no lower than the window profile in order to form a technological niche.

Next, the masonry should be restored, and along the beacons, at a given height, pour a flat area from a durable moisture-resistant mortar. To install a window sill on polyurethane foam, it is advisable to have a gap of about 20 mm from the bottom of the product to the top of the installation site, this is so that the tube of the mounting gun can be inserted into the window frame area. To install a heavy stone window sill on a layer of most special adhesives only 5 mm is required, that is, from the bottom of the window, the platform should be lowered by 35 mm, where 30 mm will be the thickness of the window sill.

If outer wall sheathed with drywall on a metal frame, a horizontal jumper passing under the window should be placed at the correct height. A common mistake novice drywall installers make is setting it too high.

A very important point in the preparatory work is to check the evenness of the lower edge of the window block. Certain problems are caused by poorly manufactured or incorrectly installed windows from PVC. Very often, at the junctions of the vertical and lower horizontal profiles, there are burrs that make it impossible to press the window sill tightly against the window - they must be cut with a knife. Another common defect is the shape of the lower profile in the form of one or more arcs, curved upwards with their middle. Its presence is easy to check by stretching the thread along the bottom edge of the window from corner to corner. If a thin plastic window sill can be easily pressed against the window with wedges or foam, then with rigid products made from other materials everything is much more complicated, they only emphasize all the irregularities. As a result - very ugly cracks that will have to be sealed with all kinds of sealants. The reality is that even in new buildings of the elite class, it is necessary to repair the plastic window blocks installed by the builders - cut the foam from under the window, remove the wedges and fasteners, dismantle the double-glazed window and different ways align the PVC profile. Sometimes the case ends with a complete reinstallation or replacement of defective windows.

How to install and fix the window sill

No matter how accurately we have made preliminary measurements, before installation, the window sill often has to be cut a little, especially in places where it enters the walls. Wood and MDF, chipboard are best cut with an electric jigsaw with a metal file, but a plastic or stone window sill is cut with a grinder with a diamond blade.

To firmly press the window sill to the window, it is necessary to use wooden or plastic wedges. They are prepared based on the thickness of the product and installed near the window lintel with an interval of 400-500 mm. Some crafters prefer to pre-glue them to the substrate so that they do not move during installation. The correctness of the selection of wedges is checked by trying on the window sill dry - the product must enter tightly.

The installation profile (window plate) should be carefully smeared with silicone to seal the abutment, the protruding mass can then be cut off. The end parts of the window sill made of MDF or chipboard are also recommended to be covered with a layer of sealant, especially if there is damage to the protective coating.

The window sill is installed in its place and centered relative to the axis of the window or the lines of the side slopes. Wedges are also installed under its front part, adjusting the level of the window sill. In most cases, the cornice of the window sill is made lower than its base, pressed against the window by 2-3 mm, so that moisture does not accumulate near the junction.

A window sill made of MDF, chipboard, wood, plastic can be additionally fixed by screwing it with long self-tapping screws through the window installation profile; for this, it is necessary to remove the outer ebb.

So that the foam, expanding, does not squeeze the window sill up, it is necessary to put 2-3 spacers going from the product to the top of the slope. We recommend installing even wooden beams along the entire length of the window sill and on top to distribute the pressure from the spacers. It is convenient to adjust them with the help of wedges. Options with placing cargo from improvised materials on the windowsill sometimes play a cruel joke with the masters, everything ends with a re-installation.

Now you can foam the space under the windowsill. The foam should be applied moderately, but evenly, without gaps, not forgetting its ability to expand greatly. You need to carefully fill the places where the side parts of the window sill enter the wall with foam, keep in mind that this is an important element of thermal insulation.

Stone window sills are not recommended to be mounted on foam, as there are cases when, during its expansion, a marble product was broken along the veins. It is better to install them on a special glue, for example, CM117, CM115 and the like. For window sills made of onyx and light marble, it is better to use white glue, which will not leave marks in case of accidental contact with the front surface.

Comb with tooth right size, about 6-8 mm, the adhesive composition, preferably in one continuous movement, is evenly leveled on a pre-prepared base. The notched trowel should be driven as vertically as possible - only in this way the height of the ridges will be the same. With an even spatula, the stone window sill is covered with glue on the back side with a thin layer and set in the design position.

If the window sill has a large overhang, then special corner brackets are used to fix it. They are fixed with one shoulder to the load-bearing wall with an interval of up to 500 mm, but not less than three pieces per product. Often this part of the bracket is recessed into the cladding and sealed with mortars. The window sill is screwed to the consoles from below by means of short cylindrical screws.

After the foam or glue is completely dry, usually done the next day, you can remove the spacers, install the end caps, and start embedding the junctions.

How to protect the window sill from damage

The first thing you need to pay attention to is the correct storage of window sills at the facility. Products made of wood, PVC, chipboard are best stored in pairs, with front surfaces to each other, between which soft gaskets should be inserted. Stone window sills are stored in an upright position, they should stand on two bars with an edge, leaning against the wall at a slight angle.

Before installing any window sill, it must be covered with sheet polyethylene using masking tape, or with a special film that does not leave adhesive traces. Remember that there is still a lot of painting and installation work ahead, and this is the danger of contamination and mechanical deformation.

Attention! The factory protective film must be removed even before the installation of the window sill in order to be able to check the quality and integrity of the front cover.

Window sills made of natural stone are able to absorb various substances with the formation of hard-to-remove stains, therefore, after installation, they are immediately treated with protective compounds that close the pores of the front surface.

After installation, strips of plasterboard, GVL or other similar materials should be laid on top of the film, precisely cut along the visible contour of the window sill.

Marble products are recommended to be preserved with a protective wooden shield, paying special attention to the cornice of the product. The hanging end is the most vulnerable spot; it is covered with a bar sewn in front. The casing must be securely fixed in the opening and rest on the polished surface through soft pads.

Not to be overlooked there is another very important nuance, which directly affects the correct functioning and durability of the window sill - the distance between the bottom of the window sill and the heating radiator should not be less than 100 mm.

The internal window sill is an integral part of any plastic window. Such a design is needed in a dwelling for additional insulation the junction of the window frame and the wall, as well as to ensure that the window has a finished look. It has the following advantages over other materials:

wooden structures need constant care, and are also damaged quite quickly;
stone window sills are distinguished by rather heavy installation, which is unrealistic to implement;
plastic structures are reliable, durable, beautiful;
have a long service life;
are easy to install;
plastic sheet is resistant to moisture;
the material has an affordable price;
plastic is resistant to chemicals;
the material is plastic and light in weight, it is easy to cut and install it with your own hands;
the canvas has high thermal insulation;
For installation, you do not need special tools, you can get by with improvised tools.

In this article, we will talk about how to properly install a plastic window sill on a window, since such designs have recently been very popular.

Preparatory stage of work

Before proceeding directly to the installation, you need to prepare workplace. To do this, you will need the following materials and tools:

level;
jigsaw;
roulette;
hacksaw;
pencil;
mounting foam;
foam gun;
perforator;
drills for puncher;
hammer;
chisel;
wooden bars;
bit.

The window sill is installed in such a way that it enters the side wall, so it will be necessary to cut out connectors about two centimeters deep in the slopes.

To carry out this procedure, you need to attach a plastic window sill to the wall and make appropriate marks on it with a marker, then carefully knock out the grooves. Such an operation requires maximum concentration and accuracy, otherwise it will take a long time to restore the slopes.

Important! In order to minimize damage to the slopes, they should be handled very carefully during the entire installation process.

The slopes are made of gypsum plaster. In this case, the procedure can be carried out with a hammer or chisel.
Concrete slopes. Then make holes for plastic window sill can be done with a perforator.

After performing all the above manipulations, it is necessary to clean the stand profile and the lower part of the window from pieces of plaster and dust, since these materials are used to install the window sill. Then the cleaned surfaces are moistened, it is better to use a primer for these purposes, which strengthens the surface.

Note! In order to prevent the appearance of drafts from the window, it is necessary to blow out all the cracks of the window frame well with foam.

Fit to size

Do-it-yourself window sill installation is not a complicated procedure that requires minimal cost funds and time. However, each window frame has its own characteristics: bulges, roughness, cracks. Therefore, before installation, if there is a finished canvas, it is necessary to cut a blank for the window sill from it. For this, the width and length of the future structure is calculated.

It should be understood that the length of the canvas should be slightly larger than the width of the window, and may go beyond the boundaries of the slopes. Basically, this output value is five, six centimeters.

The width is calculated by the formula: the width of the protruding part of the window sill + the depth of penetration of the canvas into the stand profile + the width of the surface under the window sill.

Also, on the sides of the plastic blank, you need to cut rectangles that allow it to easily enter the slope. Cutting plastic is pretty easy. To do this, use a hacksaw, grinder or electric jigsaw. If notches appear when cutting the material, then you should not worry, since all defects will be hidden by plastic overlays.

When the blank is made, it must be tried on. To do this, place a plastic blank on the surface of the window sill and slide it over the slopes and the stand profile. At this stage, it is necessary to eliminate all inaccuracies in the measurements, if any.

Installing a window sill horizontally

Before the final installation of the plastic window sill, the canvas must be leveled. To do this, linings are placed on the surface of the base. Such an operation is quite simple to perform on your own. For a regular window, you will need two linings, and for a balcony window, three.

Wedges must be placed strictly at the level of the window, such a procedure makes it possible to qualitatively align the window sill blank before installing it. Then you need to set the optimal angle of inclination. Such manipulation is required to eliminate condensate in a natural way. To do this, the edge of the slab is lowered by several degrees, and the slope angle is measured with a building level. In order for the opening to be even, these parameters should be checked in the middle and along the edges.

You need to adjust the level with linings. For wedges, it is better to buy special plastic elements in advance, but wooden bars can also be used. It is necessary to mount a plastic window sill in such a way that between the canvas and window frame there were no cracks. For this, clamping plates are used. Which are attached to the stand profile.

Installation (propenka) of the board

In order to properly fix the window sill yourself, you must perform the following steps:

Once again moisten the bottom of the opening and the slab.
Clean the part of the canvas that will be installed under the slopes from the protective film.
Then, using mounting foam, blow out the gap between the profile and the bottom edge of the opening.
Then apply a wide layer of foam on the entire surface of the base, especially carefully treat the far corners. At this stage, it must be taken into account that the thickness of the foam should not exceed the thickness of the installed wedges, otherwise, when solidifying, the material can greatly lift the plastic window sill.
Next, to evenly distribute the load on the plastic window sill, you need to put a load. It is recommended to do this inner edge boards.
The window sill is installed, now it remains only to wait until the mounting foam dries.

Installation of a window sill on a balcony

In our time, it has become popular to install not only windows from plastic, but also balcony structures. Such material retains heat well in the apartment and saves usable space. However, it should be understood that the installation procedure itself is quite expensive. Therefore, many residents of multi-storey buildings perform the procedure on their own.

Before you start replacing the plastic window sill, you need to prepare metal brackets. They are necessary if it is not possible to get the canvas under the window frame. The brackets are fixed to the parapet with anchors, which increase the load on the PVC board and reinforce the entire structure.

Brackets are installed at a distance from each other, which does not exceed one meter. After installing the panel, you need to check the angle of inclination with a building level. Before fixing the holders for the canvas, you need to tighten the thread well. This operation makes it possible to align the PVC board horizontally.

After the brackets are installed, we proceed to the installation of the window sill itself. It is fixed with screws at the bottom of the structure. It is recommended to do this with a screwdriver.

After installing the plastic window sill on the balcony, the entire surface of the PVC board should be treated with a special hermetic substance. Such manipulation is necessary to eliminate gaps and other irregularities.

Note! Unlike installing a window sill in a house, there is no need to use mounting foam on the balcony, since all components of the structure are quickly and securely attached.

Replacing the window sill in a wooden house

Replacing a window sill in a wooden house is almost the same as installing it in an apartment. First, the old canvas is removed, then preparatory work. To do this, the slopes on the sides are put in order, such a measure allows the PVC board to securely take its place.

In order not to have to cut the plastic, and the canvas is freely fixed, it is recommended to cut the wooden sidewalls yourself. For this procedure, you will need a hammer and chisel. Thus, you will get the grooves on which the fastening will be carried out.

After that, wedges are placed on the surface of the opening. The installation of the canvas is carried out exclusively on them. The position of the pads is regulated and the position of the plate is checked by the building level. Then all the gaps are blown out mounting foam.

As you can see, installing a plastic window sill is not a laborious procedure. In order to implement it yourself, you must follow the following recommendations:

be sure to moisten the surface before using the mounting foam, since the material polymerizes better in humid conditions;
too much foam should not be used, since the material, when solidified, increases significantly in size and can greatly lift the canvas up;
if you do not have the opportunity to get the PVC board over the slopes, then you should carefully take all the measurements so that the slab lies perfectly on the base;
all joints must be well treated with a hermetic agent.

If you have certain knowledge, you can not call specialists, and do the installation of a plastic window sill with your own hands.

Installing a plastic window sill with your own hands

Many people want to have modern metal in their home. plastic windows, and many have already installed them. But in addition to installing a double-glazed window, you need to take care of finishing the opening. It is decorated with wood, stone, or simply plastered on a concrete surface. The most correct option is to cover the opening with plastic and install a PVC window sill. We will tell you what advantages PVC finishing elements have, consider how to install plastic window sills and give detailed instructions by installation.

Advantages and disadvantages of PVC window sills

PVC window sills are very popular due to their durability and moisture resistance.

The popularity of plastic products is due to the fact that they have a lot of advantages over finishing elements made from other materials. The advantages of plastic window sills include:

attractive appearance;
ease of cleaning from dust and dirt;
long service life;
high strength, due to the presence of stiffeners;
harmlessness to health (PVC window sills are made from environmentally friendly and non-toxic materials);
high moisture resistance.

In addition, when fixing the product, mounting foam is used, which prevents the penetration of dampness into the room and, as a result, the appearance of mold in the house.

Plastic window sills also have disadvantages, but there are very few of them. So, PVC plates are prone to scratches in case of careless operation. Hot objects should also not be placed on them - this can lead to deformation of the surface and loss of a beautiful appearance of the finishing element.

Installation methods

Installing a window sill with wooden linings is time-consuming, but this method is the most reliable.

There are several methods for installing PVC products. Let's consider each of them.

The first method, the oldest, involves fixing the element with a special composition. Nowadays, this method is used extremely rarely, as more convenient and reliable ones have appeared.
The fastest installation of the window sill is carried out using self-tapping screws. First in window frame holes are drilled into which the hardware is screwed. The junction is treated with acrylic sealant, after which the edge of the window sill is brought under the double-glazed window and fixed with self-tapping screws. To give maximum rigidity to the slab, special linings are placed under it and the resulting place is blown out with mounting foam.
The next method involves the installation of PVC window sills using spring clips. These fasteners are screwed to the substitution profile of the product with self-tapping screws. After that, the plate is mounted in the groove formed between the window frame and the bracket, and the product is installed.
In the last version of the installation of plastic window sills, no fasteners(self-tapping screws and staples). This is the most time-consuming method, but also the most reliable. Its meaning is that the wedges are driven under the plate until its edge is pressed against the frame as tightly as possible.

Each method has its pros and cons. For example, it is undesirable to install a window sill using self-tapping screws near the opening sash. Installation options for PVC window sills differ only in the way the product is fixed under the frame. The remaining stages of work here are absolutely identical.

What will be required

Before proceeding to the installation, it is necessary to prepare materials and tools. As the first rule of professional builders says, the quality of work largely depends on the class of tools used. Yes, with good fixtures and work easier, and their service life is longer. Especially when you consider that tools are likely to be needed in the future, since window sills are often installed under each window of a house or apartment. So, for work you may need the following materials and tools:

PVC window sill;
electric jigsaw, grinder;
mounting foam cylinder and a special gun;
building level, measuring tape, pencil;
self-tapping screws or staples (depending on the chosen method of installing the window sill);
wooden wedges (thin boards and the like);
chisel and hammer;
stationery knife;
spatula and primer.

Preparatory work

Taking measurements

The product should protrude no more than 8 cm

To qualitatively install any window sill, you must first take measurements. This moment is extremely important, because both the appearance and the strength of the future structure depend on it. Here, in addition to the properties and characteristics of a PVC product, many additional parameters should also be taken into account. For example, there must be a certain distance between the battery and the window sill. Otherwise, air circulation will be disturbed, which will lead to a deterioration in the microclimate in the room.

When taking measurements, it is worth remembering that the length of the installed plate should be slightly greater than the distance between the side slopes. The fact is that the product is inserted into the grooves made with a depth of 2–3 cm. As a rule, the window sill is mounted above the battery, so the size of the front protrusion of the plate should be no more than 8 cm. If this figure is greater, then the PVC plate will not allow hot air to rise from the radiator to the window. And this will lead to the formation of moisture. As for the vertical distance between the battery and the window sill, it should be more than 10 cm.

Due to the fact that the product is installed directly under the window, modern models are equipped with a special profile with the possibility of fixing the ebb.

Trimming the window sill

In addition to a jigsaw, you can use a grinder or a special hacksaw to trim a plastic window sill.

In accordance with the measurements, cut the blank of the window sill of the required width and length. It is advisable to cut PVC products with a grinder. Using this power tool will allow you to achieve perfectly smooth edges. In the absence of a turbine, you can use a jigsaw. Less often, pruning of a PVC window sill is carried out with a hacksaw for plastic. But you need to cut it very carefully.

Do not apply too much pressure to the saw, as this may cause chips and cracks on the product.

When working with plastic, you need to remember the safety measures. This is a rather fragile material, so when it is intensively cut, small particles can fly out. Wear safety goggles and work gloves.

Window opening preparation

To make grooves for the window sill, use a chisel and a hammer

Immediately before installing the window sill, it is necessary to prepare the place of its installation. At this stage, grooves are made in the side slopes with a chisel and a hammer. After that, the installation site of the product is cleaned of debris and primed. Next, special spacers or wedges are attached to the window frame. They can be fixed with a plaster solution. Stands are used to set the slab at the correct level and at the required inclination. At the same time, keep in mind that the plate should be located at an angle of 1-2 degrees towards the room. So water from watering plants or condensate will drain, and not collect under the stove. Then attach the window sill and check how tight and even it becomes. Trim the edges if necessary.

Apply a layer of moisture-resistant primer to the installation site of the window sill

Important: If you find any gaps in the window opening, they must be blown out with mounting foam.

Assembly and installation instructions

Use a special gun to blow the mounting foam

As noted earlier, the fixation of the product can be performed in several ways. We will consider the latter - using wooden spacers and mounting foam, as it is the most reliable and very popular lately among people doing DIY repairs. The procedure is as follows:

We insert the window sill into the prepared place. At the same time, we use the building level and wooden beacons, which we have in increments of no more than 80 cm.
At the front end, we install supporting wooden blocks under the slab. The distance between them is no more than 50 cm. In this case, the bearing elements should not go beyond the plane of the wall. The distance from the blocks to the side slopes is 10 cm.
Re-check the angle of inclination of the window sill with a level. If it does not correspond to the previously specified value, then adjust the pads in thickness.
We blow out the hole between the slab and the concrete surface with mounting foam. But not completely, but only to fix the product.
We evenly place the weight on the plate. This will prevent the foam from lifting the sill. It is important here not to overload the structure, as its surface may be deformed. Often, 3-4 tanks of water with a volume of 5 liters are used as cargo.
We blow out all the free space under the windowsill with mounting foam. Use a special gun so that the sealant does not splatter on the sides and does not get on clothes.
After that, we leave the window sill alone for 2-3 days so that the foam completely hardens. Cut off excess binder with a clerical knife.
In case of subsequent detection of cracks under the slab, treat them with acrylic sealant.
At the final stage, plugs are installed on the ends of the window sill. To do this, use glue for PVC products. At the end, it remains only to remove the protective film from the product.

Place a few water bottles on the windowsill to keep the foam from lifting the stove.

Important: The window sill should fit tightly with the window frame, and the gap between the slab and the walls should not exceed 4 mm. The “ears” of the product (the part protruding beyond the internal slopes) should also be pressed tightly against the wall.

Video instruction for installing a PVC window sill

Installation of plastic window sills is not an easy job that requires appropriate knowledge and skills. When installing such products with your own hands, be careful and follow the above rules, because the price of a damaged PVC plate is much higher than the cost of its installation.

How to install a window sill on plastic windows

Greetings, friends!

In continuation of the topic of installing plastic windows, I want to teach you -.

Why do I prefer plastic window sills?

This is because wooden ones, although they are environmentally friendly, are very picky in terms of care: they are afraid of all kinds of detergents, they require periodic staining, they are afraid high humidity and fire, and their price is disproportionately higher.
Unlike wooden window sills, PVC window sills have a number of advantages:

Due to its design of several air chambers, the plastic window sill is an excellent heat insulator
PVC window sill does not require painting, it also does not rot, is not afraid of mold, etc.
Plastic itself is a very durable material.
It is not afraid of temperature changes, resistant to sunlight, is not afraid of moisture and washes well ...
Very lightweight yet durable
Optimal price - quality

In order to correctly install the window sill on plastic windows you don't have to be a super master. The work is not very difficult and with a little hand-knocking everything should work out for you. Read the article carefully - in it I will try to cover all aspects as much as possible.

How to choose a plastic window sill

1. Window sill covered with PVC film

The cheapest option. It does not tolerate temperature changes very well, it quickly loses its appearance, as it quickly absorbs dirt and dust. Its only advantage is its cheapness.

2. CPL coated laminate

Such window sills are obtained by pressing paper sheets impregnated with melamine resins. Very resistant to temperatures and chemicals.

3. EPL-coated plastic

Window sills with EPL coating are a premium class. Gorgeous specifications, special antistatic coating, a huge range of design solutions, etc. and so on.

Required Tool

The window sill of the required width
plastic plugs for it
Plastic wedges or bars, if not available
Metal saw or electric jigsaw
Mounting foam
Building level
Roulette
Well, preferably a primer

Preparing for installation

We have decided which window sill to choose for plastic windows and we can proceed directly to preparation. If, after dismantling the old window sill, side grooves remain, then this is good, but if there are none, then you will have to cut them out. We use a puncher or a chisel for this. The depth of the groove should be about 6 cm on each side.

The next step is garbage collection. With a brush, clean as much as possible work surface.

Then we prime. The primer is necessary to increase the adhesion of the mounting foam, and we will also exclude fine dust from the work.

Friends, if during priming you stained the window, then you should immediately remove the remnants of the primer, because traces may remain in the future.

The final stage of preparation is to control the gap between the window sill sheet and the base. The distance should not exceed 4 cm, as this optimum thickness for polyurethane foam polymerization. Exceeding the allowable limits will lead to the appearance of "shells" and voids in the frozen foam, which is not good: (If you have a greater distance, then you need to build up the base with plaster or in other ways - it all depends on the thickness :)

How to install a window sill on a plastic window

So, the preparatory work is completed and you can proceed directly to the installation.

Installation of a window sill on mounting foam

Competent measurement is very important - whether it is a window sill or a plastic window.

Do not forget about entering the wall so that there are no gaps under the future slopes.

After the window sill is cut to size, it is necessary to put several wooden blocks on the base perpendicular to the window (masters usually use plastic slats). This creates stiffeners that take on the main load. The optimal distance between the substrates is 40 cm, but may vary depending on individual characteristics.

The bars should be set with a slight slope towards the room so that the accumulated condensate does not cause mold.

Distance between wooden slats foams up.

Friends, so that the foam does not “crush” the window sill, I use foam with the lowest expansion coefficient. For example - Titan 65.

Then you must immediately measure and put plastic side plugs on the window sill. You can fix them with building glue.

We drive the structure ready for installation into the support profile and install it on the load on the structure so that the mounting foam does not lift it up. You can use multiple 5 liter bottles with water.

Let the window sill stand for a day until the foam is completely set.

Then acrylic or silicone sealant close the gaps.

Friends, almost missed important point. In order to create a circular circulation of air in the room, so that the windows have enough heat and frost does not form on them, it is necessary correctly install the plastic window sill above the battery. The inside of which should not completely cover the heating devices. Heated air should rise from the battery up the window without hindrance. This creates a circular circulation of air in the room.

Installation of a window sill on a cement-sand mortar

Friends, if the width of your future window sill exceeds 600 mm, then I do not advise you to mount it on foam, since under increased loads there is a high probability of deflection, which is not very pleasant - especially if the repair is already over. In such cases, a cement-sand mixture prepared in a ratio of 1 to 3 will help you, where 1 is cement and 3 is sand. You need to knead the mixture immediately before installing the window sill.

Unlike mounting foam, the interaction between mortar and plastic is not very good and slippage is possible. To avoid this, there is one tricky trick - self-tapping screws are screwed onto the inside of the window sill. It is advisable to make three rows with a distance of 1.5 cm. The head of the screws should stick out by 1 cm.

We apply the finished solution to the base and install the prepared window sill in the supply profile.

Getting to the right level.

The remains of the solution under the windowsill are removed with a spatula.

We give the window sill a two-day “rest” and you can proceed with the installation of slopes.

How to install a plastic window sill - video

Well, that's basically it, my friends.

I think the question is - how to install a window sill on plastic windows- I gave a complete answer.

How to install plastic window sills and slopes with your own hands

Modern construction trends imply the use of the most ergonomic materials. The requirements of an ordinary buyer are as follows - the material must be light, durable and inexpensive. Previously, wood was almost universally used, but now it is considered a premium material. Instead, plastic came to him - it is more durable, cheaper and has almost limitless decorating properties.
Most often, plastic is used in metal-plastic windows, which are now installed almost everywhere. In addition to them, it is necessary to put a window sill and slopes. Each element performs important role in everyday life, and which selection and installation must be approached with particular care.

Installation technology

Most often it turns out that the main technical purpose of these products is completely forgotten. They are usually used as a flower stand, especially large and durable options can be designed as an extension and extension of the working space in the kitchen or office, you can even place a comfortable sofa for reading books there.

In addition to all this, the window sills with their protrusion delay the rising from the batteries warm air at a low level, which allows you to warm up the living space much better.

Immediately after installation plastic window you need to let it stand for a couple of days, after which the installation of the window sill begins. You need to prepare the tools:

sharp construction knife; hacksaw for metal; sandpaper; hammer and chisel (if any, an impact drill or puncher); wooden or plastic pads for leveling the surface; building level.

old version

construction vacuum cleaner

Sprinkle the prepared work surface with ordinary water using a broom or a mechanical sprayer - it will be much easier for the mounting foam to stick to moisture, which will make it much easier to work with it. This stage is very important, because. It is the mounting foam that is the main fixing material. Three holes are intended for installation in place - two side grooves and a recess in the window itself. The last hole should accept the window sill as clearly as possible - an unsuccessful gap will be visible during the operation of the dwelling. The most important part of the installation is setting the surface according to the level. To measure indicators, the mounting level is used. To adjust the angles of inclination, plastic or wooden plates are placed under it. The slope should be set slightly towards the room so that moisture does not linger in the groove between the horizontal surface and the window and mold and dampness do not start there.

After the correct level is set, you need to press down the new surface with something heavy, bricks wrapped in rags are ideal. They will hold the window sill when the mounting foam swells. All empty space under it is carefully and carefully filled with mounting foam. Designs allow to stand for at least a day. After the foam dries, its remnants are cut off with a knife - and the window sill is ready for use.

slopes

Conclusion

Plastic windows are perfectly equipped with ergonomic window sills and slopes made of the same material. Their installation does not require the involvement of specialists, they will last for decades. Care is very simple and immediately pays for all installation costs.

A detailed video instruction can be viewed on the video.

The window sill is not only a decorative element on which you can place flower pots with plants, household trifles, but also a constructive detail. Standard installation window sill on plastic windows can prevent a sharp movement of warm air from the radiator to the ceiling. In a similar way, heat exchange is regulated inside the room, the lower structures are heated. Let's look at how to install a window sill on a plastic window yourself.

Types of window sills

Window sill blocks must be made of wear-resistant, high-quality material. Now in the construction market there is a wide selection of products for different tastes and budgets. The most popular designs for windows are made of stone, wood boards, and plastic.

PVC window sill board

Such window sills are distinguished by good operational parameters and reliability. They perfectly tolerate conditions of high humidity, exposure to ultraviolet radiation, almost do not deform and do not become moldy.

Another advantage is the ease of installation. Installation work will not take much time. This window sill does not need to be coated or painted. Such designs are inexpensive, which is why they are in demand.

PVC products are very durable due to special stiffening ribs. Their surface is laminated, for which films based on acrylic resin or melamine.

Composite systems

This type of construction is created from 2 parts - a board that lies at the base and in the top coating (can be made of laminate, special film or veneer).

These products include window sills made of WPC, MDF or chipboard. Often the basis of chipboard are sawdust of deciduous and coniferous species.

Now many apartment owners correctly believe that installing chipboard window sills on plastic windows will be practical and economical option. Over time, this raw material does not swell from moisture and is not damaged. MDF boards are made from fine chips, which are processed in a special way and combined into blocks. This material is environmentally friendly - it is safe for human health.

The window sill, consisting of fiberboards, is quite durable. The owners will not have to worry about cleaning such products. For washing, it is better not to use powders that scratch the surface. During installation work, it is recommended to lay thermal insulation at the ends.

Window sills made of WPC (wood-polymer composite) consist of polymers and special fillers from natural material. Plastic windows with these window sills have all the advantages of wooden structures, they are not subject to the appearance of mold. The surface of this product is more durable, and their difference from wood structures is their resistance to fire.

This profile may resemble plastic or MDF depending on the amount of wood component used. WPC window sills can be varnished or enameled, finished using different kind films made of synthetic materials.

wooden window sill

For facing the space in the window opening, wood has been used for a long time. The highest quality products are made of ash, beech, cherry, oak. To create window sills, materials of other valuable species are used, for example, maple, mahogany. More economical are structures made of larch or pine.

Processing of raw materials is carried out by a large number of stages. It is dried, then sanded, coated with wax mastic and natural oils. The structure is treated with a special waterproofing impregnation and a layer of varnish. This ensures the quality and ease of use of the finished product.
The cost of a plate made of natural wood is quite high. Window boards made of ash are 30% more expensive than oak, due to the fact that ash perfectly retains its shape. On window sills made of soft coniferous trees over time, damage and pits may appear. These window sills are cheaper.

For plastic windows, wooden window sills have many advantages. They are distinguished by good thermal insulation performance. This choice will be the best for the owners if you want to use a similar window sill in the loggia or kitchen. Often, the window sill block is used as an additional work surface. Hot objects are placed on it, moisture also gets on the windowsill. In order for a product to withstand such a load, it must be durable and solid.

PVC window sill installation

Installation of a window sill to a plastic window requires certain skills from workers. Improper installation of the window sill can lead to poor thermal insulation of the entire window construction. The installation of this product is often carried out simultaneously with the replacement of the window frame. In terms of the consumption of financial resources and the cost of materials, it is more economical, faster and more convenient. Let's study the detailed instructions on how to install a plastic window sill.

Determining the size of the window sill

Window sills that are made of PVC are best suited for plastic windows. It is necessary to start work by calculating the dimensions of the window sill for the desired plastic window. To determine how long the window sill should be, you need to measure the width of the opening with a tape measure. 60 mm should be added to the value obtained. On each side, the window sill should protrude at least 30 mm beyond the slopes. Otherwise, the plastic corner with an F profile, which is used for the installation of slopes, will significantly protrude beyond the window sill, which is considered unacceptable.

The indicator of the width of the plastic profile is determined quite simply.

It should be remembered that the value of the permissible protrusion of the window sill from the opening is from 50 to 70 mm. Otherwise, it will block the battery, which will prevent the passage of heat.

This can cause not only fogging, but also the formation of frost on the windows. Under the window structure itself, the window sill must be brought in by approximately 20 mm. Accordingly, these figures must be added to the value of the depth of the window opening, which is measured from the profile to the wall.

Making a window sill blank

When installing a window sill with your own hands, it is necessary to apply the obtained indicators. Then a window sill blank of the appropriate width and length is cut out. The cutting process is carried out by a grinder, as with its help you can get perfectly smooth edges. If this tool is not at hand, then a jigsaw is also suitable for work, you just have to cut it carefully. If there is no jigsaw, then you can saw off the workpiece using a conventional saw.

How to fix if the workpiece is not included in the opening? It is necessary to cut out those parts that interfere with it. You can make the protruding parts of the window sill on the right and left recessed into the wall. After the installation process on the plastic window sill in this way, the recesses are puttyed.

The effect of solidity of the window sill and wall should be ensured. To do this, using a perforator, small recesses are made in the wall. Then you need to attach a window sill to the opening and make marks for the cuts. Rectangles that interfere with installation are cut off to the right and left. Now the plastic window sill blank is completely ready for installation in place.

Surface preparation

Before installing a plastic window sill, it is necessary to clean the horizontal surface from construction debris and dust. The question arises, how to install the product correctly?

It should be borne in mind that, regardless of the material of manufacture of the window sill, it must always be installed at a slight slope towards the room.

This is necessary so that water from glass condensation or watering plants does not collect under the frame. A slope of a few millimeters will suffice.

Before fixing the window sill to the plastic window, special wedges or spacers must be installed, which should be fixed using a plaster mortar. They are needed to set the window sill to the required level. Then linings are prepared under the windowsill. Linings should not protrude so that they do not have to be cut off in the future. Now a check is made to see how exactly the window sill can be installed.

Fixing a plastic window sill

There are several ways to attach a plastic window sill:

On two-component polyurethane foam (the most common method).
On glue using spacers. They act like a press.
On a special type of brackets. This also includes situations where the width of the window sill significantly exceeds the size of the window opening.
With the use of special retaining brackets.

Mounting foam is applied along the frame, a plastic window sill is installed, fixed. All remaining voids are filled with mounting foam. It should be remembered that the foam can expand greatly in volume, so you need to be careful and accurate. When the mounting foam has completely hardened, it is necessary to remove the spacers and check the quality of the installation of the plastic window sill using a level. Acrylic seals the places where the plastic window sill touches the frame and slopes.

Window sill care

Plates of their polyvinyl chloride must be cleaned with water and detergents. For wooden parts, it is better to use a well-wrung cloth and no abrasive materials. It is not advisable to clean the wood with abrasive products and wet it with water. The surface of the window sill must be protected from freezing. Dust is removed with a dry cloth, and every 3-4 years it is required to cover the product with a new layer of varnish, wax or paint.

A new window sill will last you longer if the following conditions are met:

Accuracy in carrying out work.
Use of quality building materials and raw materials.
The right choice of material from which the window sill is made.
Installation according to all instructions and requirements.
careful handling and regular care behind the surface.

It follows that the installation of window sills for plastic windows, as well as replacing the window sill with a new one, can be done independently. You only need to follow all the steps in the workflow.

One of the important elements of the window opening, which ennobles its appearance by closing the mounting joints, is the window sill. It can be made from different materials. However, the most demanded is plastic, which is associated with the wide distribution of metal-plastic windows. The installation of a plastic window sill consists of several successive stages, the implementation of which will ensure the achievement of optimal performance.

Metal-plastic windows have long gained authority. They are very popular among consumers due to the fact that they are characterized by high performance, easy to install and have a long service life. After replacing the window, the installation of slopes and a window sill is immediately carried out.

A metal-plastic window is a universal product, which is suitable for different variants window sill, which is selected in accordance with the stylistic task. The most common option is plastic products. This design is best combined with the material modern window, creating a single composition with it.

The plastic window sill is characterized by distinctive advantages. The product is resistant to moisture, sunlight and temperature extremes, not prone to rot, mold or corrosion. At the same time, the surface does not deform, does not change its original shape and appearance. The material is completely safe for human health, is durable (due to the presence of stiffeners), reliability, resistance to chemical attack. It has high thermal insulation properties, which is due to the presence of air chambers in the design of the window sill.

The product is inherently light in weight, which ensures easy installation of the PVC window sill, while it does not shrink during further operation. The surface does not need painting and other treatment options that prevent possible rotting or corrosion. She is easy to care for. The plastic window sill is characterized by low cost in comparison with other materials.

Despite the advantages, the plastic window sill has its drawbacks. In case of inaccurate operation, dents or holes may appear on the surface of the product, which is a consequence of the fragility of the product. If there is a glossy finish, it may be scratched, which will cause an unsightly appearance.

Important! The plastic window sill can be deformed when exposed to high temperatures, so a hot kettle or pan should not be placed on the surface.

Which plastic window sill to choose: product varieties

Before installing the window sill on a plastic window, you must select the type and size of the product. by the most budget option is the surface covered with PVC film. However, such a window sill does not tolerate temperature changes, quickly absorbs dust and dirt, which leads to the loss of its original attractive appearance.

The CPL-coated laminate product is made by pressing paper sheets impregnated with melamine resins. Such a window sill with a multilayer base is characterized by resistance to temperature extremes, chemical influences.

Most often, do-it-yourself installation of a PVC window sill with EPL coating is carried out, which is distinguished by high strength and performance characteristics. Products are produced by extruding plastic material through extrusion holes to acquire the desired shape.

The internal space is divided into several chambers with vertical and diagonal stiffening ribs, which ensures strength, rigidity and reliability of the structure, which does not bend or break. This also increases the thermal conductivity of the product.

The surface, due to the presence of an antistatic coating, does not absorb dust and dirt. Such a window sill is presented in a wide range of colors, which allows you to choose a product that matches a particular interior of the room.

The texture, color and design of the plastic window sill

According to the type of coating, the plastic window sill can be matte, glossy or laminated. The first type of product is able to fit into any interior. The surface can be painted in a variety of colors. A matte window sill brings a feeling of comfort and warmth to the environment, but such a surface is prone to absorbing dust and dirt.

Important! In case of accidental damage to the matte surface, it can be restored using a special tool.

A glossy product has a more attractive appearance. The surface has antistatic properties, so that dirt and dust do not accumulate on it. The product is easier to care for. However, the surface is susceptible to mechanical stress, and small visible scratches quickly form on it, which impair its appearance. In addition, the glossy window sill cannot be restored.

Laminated window sills are covered with a special film, which gives the products texture, increased strength and durability. To receive a product white color one layer of film is applied. The colored window sill has a two-layer coating that contains a dye. The price of installing a plastic window sill of this type is the highest and starts from 1100 rubles. for the m.

There is a separate type of product in the form of a wenge window sill, made from a mixture of PVC and wood flour. The unique production technology allows to obtain a durable, scratch-resistant and UV-resistant, durable product. The price of installing a window sill of this type starts from 1300 rubles. for the m.

The plastic window sill can be made in white, color and "under the tree". The latter option finds its application in wooden houses. It can also be used in tandem with wood windows. However, this design, unlike wooden window sill, characterized by resistance to moisture, lack of processing for further operation, long service life. Imitation "under the tree" is achieved by using the appropriate laminated film.

Important! The use of such a coating in the manufacturing technology of a window sill makes it possible to obtain a product that imitates natural stone in the form of marble or granite.

Plastic window sills are produced up to 6000 mm long, 100-600 mm wide in 50 mm increments and 600-1000 mm in 100 mm increments, which directly affects the price of installing a window sill on a plastic window. The height of the product reaches 18-22 mm.

Components required when installing a window sill and slopes with your own hands

To install a window sill and slopes on a plastic window, it is not necessary to have certain skills and abilities. Even a novice master can handle this. For achievement good result milestone is the selection of the necessary components.

When installing a PVC window sill, you will need to purchase not only the plate of a certain type, but also connecting elements, as well as a double-sided end cap. The last element is represented by a bar with two spouts, used for decorative framing of the end sides of the window sill. The plug is divided in the middle, fixing one part to the right and the other to the left of the plate. Connectors are used to join the window sill at an angle and connect it along the entire length into one integral structure.

Slopes are used to frame the side elements of the window opening. They close the mounting seams of the frame with the opening and give the window a complete, aesthetic appearance. The most common option is plastic slopes, which are characterized by strength, reliability, good thermal insulation properties, low maintenance and quick installation. The video "Installation of slopes and window sills" will allow you to familiarize yourself with the choice of elements and installation conditions in detail.

To protect the window frame from the negative impact environment from its outer side, it is necessary to install an ebb. The structure can be made of aluminum, plastic or metal. The second option is the most widespread. Metal ebbs are the most budgetary and short-lived, because they have a low level of resistance to the negative effects of atmospheric conditions.

Aluminum sills are more durable, have reliable protection from mechanical damage, thanks to a special coating on the surface, they absorb the noise of raindrops.

Ways to install a window sill on plastic windows

Before installing a plastic window sill, you should study the possible ways of installing the product.

The oldest option for installing a window sill on a plastic window is to fix the product with a special compound. Today, this method is used extremely rarely due to the emergence of more convenient and reliable methods.

The easiest way is to install a PVC window sill with your own hands by using self-tapping screws. Preliminarily, holes are made in the window frame where the hardware must be screwed. Joints for greater tightness should be treated with an acrylic-based composition. To achieve maximum rigidity and reliability of the structure, special gaskets are placed under it during installation, and the resulting gaps are filled with mounting foam.

The window sill can be installed using spring metal brackets. These fasteners are fixed to the stand profile by means of self-tapping screws. Then the PVC plate is installed in the groove that has formed between the bracket and the window frame.

There is an option for installing a plastic window sill with your own hands, which does not involve the use of fasteners in the form of brackets and self-tapping screws. The plate is installed on seat. Wooden wedges are driven under it until its surface is pressed as tightly as possible against the window frame. In this case, it is necessary to constantly check the level of the structure. The window sill should have a slight slope towards the room to exclude the possibility of condensation on the frame.

All free space that has formed is filled with mounting foam. This type of installation is the longest, but it can be considered the most reliable.

Important! After blowing out the space under the window sill with mounting foam, weighting must be installed on the plate in order to create the necessary resistance at the moment the material solidifies.

All options for installing a window sill have their pros and cons. They differ only in the way of fixing the product under the window frame, and all other stages are identical.

How to install a window sill: preparatory stage

How to install a window sill? First of all, you need to prepare the tools necessary to ensure maximum efficiency of work, and component materials, thanks to which the installation process will be simple and convenient.

To install the window sill, you will need a PVC product itself, a corner, a building level, a marker with a tape measure, a sealant for joints and seams, mounting foam to fill the gaps between the plate and the wall, a jigsaw, a puncher, a screwdriver, screws, self-tapping screws.

Many are interested in the question of how to install a window sill if the window is already there. First of all, the necessary measurements are taken. Carrying out this stage is extremely important, since the strength and appearance of the future structure will depend on the correctness of its implementation.

The length of the window sill should be several centimeters longer than the distance between the side slopes. This is due to the fact that the product starts up 2-3 cm into the grooves made in the wall. The width of the product is selected taking into account its protrusion above the radiator, which is installed below. This value should not exceed 8 cm. Otherwise, hot air will not rise to the window from the radiator, which will cause condensation.

The distance between the window sill and the stove should also not be less than 10 cm. Otherwise, a closer location will cause a violation of air circulation, which will worsen the microclimate in the room.

How to install a plastic window sill: taking measurements and preparing a window opening

Before putting a plastic window sill, the product is prepared according to the measurements taken. On the plate with the help of a marker, the required length and width are deposited. Then, using an electric jigsaw, a PVC structure is cut. Work is required to be carried out in goggles and work gloves, since plastic is a very fragile material, therefore, when it is intensively cut, small particles can fly out.

The sawing process can also be carried out using a special hacksaw or grinder. In the first case, the process will be lengthy. Using a grinder, you can achieve perfectly even edges of the product.

Important! When cutting, do not apply excessive pressure on the plate, as this can lead to cracks and chips on the product.

Before you properly install the plastic window sill, you need to prepare a seat for it. Since the structure is mounted with some entry into the side niches of the opening, it is necessary to make appropriate grooves for it on both sides in the wall. The process is carried out using a chisel and a hammer. The resulting openings are thoroughly cleaned of debris and primed.

After that, special spacers or wedges must be attached to the window frame, which are fixed for reliability with a gypsum mortar. The installation elements must be positioned in such a way that the required inclination is ensured. Then, do-it-yourself installation of the window sill on the seat is carried out and it is checked how even and tight it becomes. If necessary, cutting the edges of the structure is performed.

Important! The window sill should have a slope towards the room, which is 1-2 °.

The process of installing a window sill on a plastic window with your own hands

As mentioned earlier, there are several ways to fix the product when installing a plastic window sill. On this stage the most popular and reliable option is considered, which involves the use of wooden spacers and mounting foam.

How to install a window sill without a support profile? The product is mounted on a prepared seat. Under the structure, wooden beacons are installed in increments of 80 cm. They ensure the horizontality of the structure, which is controlled by the building level.

Under the plate at the front end there are wooden blocks, the distance between which should be about 50 cm. It is necessary to ensure that the load-bearing elements do not go beyond the plane of the wall. The distance between the wooden blocks and the side walls should not exceed 10 cm. Before placing the window sill, recheck the horizontal position of the window sill. If the value does not match the previously obtained result, the pads are adjusted in thickness.

To pre-fix the window sill, the cavity between the slab and the concrete surface must be filled with mounting foam, a can of which is placed in warm water a few minutes before work begins. To prevent the binder from lifting the window sill at the time of expansion, a load is placed on the slab. Further, all free space is thoroughly filled with foam.

Important! Do not overload the structure excessively so that the window sill does not deform.

In this position, the window sill must be left alone for 2-3 days. Excess mounting foam should be removed with a clerical knife. If possible gaps are found, they are filled with acrylic sealant. At the end of the installation process, to give the structure a complete look, special plugs are mounted on its ends with glue. After installing the window sill, you can proceed with the installation of slopes.

Installing a plastic window sill on the balcony

Modern balconies and loggias are actively glazed through the use of metal-plastic double-glazed windows. This process is accompanied by the installation of a PVC window sill. The installation of the window sill on the balcony is mainly carried out at the time of glazing. However, this can be done later with your own hands. How to install a plastic window sill with your own hands, so as not to regret the work done?

How to install a window sill on the balcony if the window is already up? To do this, you need to prepare metal brackets. They are needed in the absence of the possibility of placing a structure under an existing window. Metal brackets should be fixed to the parapet with anchors. These elements will help strengthen the window sill, which will lead to an increase in payloads.

The distance between the metal brackets should be no more than 1 m. Using the building level, check the horizontal position of the fasteners. Before fixing the holders, to simplify the installation process, the thread is pulled strictly horizontally.

After the brackets are fully fixed, the window sill is installed on the loggia or balcony. It is fixed at the bottom of the plate with self-tapping screws. After the installation process is completed, the structure is treated with a sealant. The procedure is performed in order to get rid of the cracks that are formed as a result of the presence of irregularities along the edges. You can familiarize yourself with the installation process in detail by watching the video "Installing a plastic window sill".

Important! When installing a window sill on a balcony, in contrast to installation in a window opening, mounting foam is not used to fill the voids.

The procedure for replacing the plastic window sill

Over time, a PVC window sill can be damaged or lose its original appearance as a result of scuffs and ingrained dirt. In this case, it is important to know how to change the window sill.

Before removing the plastic window sill, preparatory measures are carried out, which are determined by the type of slopes. They can be monolithic, that is, installed using plaster, or panel (made of PVC boards or sandwich panels). The window sill is mounted under the slopes, so before removing it, they are partially or completely dismantled.

When using plastic slopes, the profile used to frame the corner is removed. Then the finishing panel is carefully opened, for which the sealant seam is first embroidered. Next, the mounting foam is removed from the plane of the support rails, the junction of the edge of the structure is cleaned. This is necessary for easy removal of the window sill.

If the slopes are finished with plaster, to replace the window sill of a plastic window, two horizontal lines should be drawn along the edges of the opening with an indent of 25 mm from the top of the window sill. According to this marking, trimming is carried out using an angle grinder with a diamond wheel. The process is carried out with the utmost care to eliminate the possibility of damage to the frame. Using an angle grinder, an undercut is carried out along the plane of the wall, the depth of which is equal to the width of the protrusion of the structure beyond the slope.

Helpful advice! The installation depth of the window sill usually reaches 30-40 mm, so a 180 mm circle will be needed to dismantle the slopes.

Since the plate, with the modern installation method, is not attached to the window frame or support profile, but is fixed with mounting foam, simply tearing off the product will be quite problematic. Before removing the window sill, the structure must be cut into fragments using a jigsaw. If the plate is placed on cement mortar, to separate the structure, you should use the angle grinder. Next, each element is removed from the seat.

If the window sill was fixed to the supply profile, then the tide is removed from the outside of the window. From the profile it is necessary to unscrew a few screws.

Methods for the restoration and repair of a plastic window sill

With prolonged use, the plate loses its original appearance. The surface is heavily soiled, scratches and cracks may appear on it, traces of hot objects, flower pots, stains from impact chemicals and sunbeams.

First of all, the question arises of how to wash the plastic window sill from stains. To do this, you can use ordinary detergents and cleaning products, but they do not always bring the desired result. In this case, it is not necessary to change the design to a new product. You can explore several ways to update a plastic window sill.

The PVC product is covered with a protective film, which turns yellow or peels off over time. To eliminate such a defect, you can use a special laminate wax or a solvent-based cleaner for plastic. The surface is covered with the selected composition, after which it is wiped with a dry soft cloth.

To restore the window sill, on which small cracks and scratches appeared, you can use specialized mixtures with a plastic effect. They are sold in powder form. After drying, the material acquires the same properties as plastic. A thick putty mixture is prepared from the powder and water, which closes up all visible defects.

Helpful advice! To achieve the maximum effect for the preparation of the finished composition, it is recommended to use a primer instead of water.

The finished solution is applied to visible damage. After that, you should wait 10-15 minutes and grind the patched places with sandpaper, and the surface can also be polished special tool for plastic.

To seal deep scratches, it is better to use liquid plastic, which penetrates into the pores of the material and sets quickly. In order for the restored surface to have a uniform texture, it can be additionally pasted over with a self-adhesive decorative film.

How to make a window sill from an old plate and give it an aesthetic look

Simple and accessible way Restoration of a plastic window sill is covering the surface with a laminated film. The material is presented in a wide color scheme, in a monophonic design, and it can also imitate a variety of textures.

The surface is pre-leveled with a putty mixture. A film of the required size is cut out with a margin of 3 cm along the edges. After removing the inner layer, the self-adhesive product is evenly distributed over the entire surface, excluding the formation of blisters or waves.

Another option for resolving the issue of how to update a plastic window sill is to restore it with a PVC overlay, which can be used for slabs no more than 6 cm thick. It is simple and economical way, allowing you to quickly solve the problem with a swollen or cracked window sill. The overlay is made of pure polyvinyl chloride, which is characterized by strength, moisture resistance, resistance to ultraviolet rays.

Restoration begins with filling large cracks with glue, after which it is necessary to degrease the surface and spread it with adhesive. An overlay of the required size is applied to the window sill and pressed with a load. The surface must dry for 6 hours. The end edge is heated with a building hair dryer and bent to the shape of the window sill.

Important! In the case of a glossy or laminated overlay, heat treatment is not used, as the product will lose its attractive appearance.

Installing a window sill under a plastic window is a simple undertaking. However, to achieve a good result, it is important not only to choose the right product, but also to follow a certain algorithm for the implementation of installation work, which will be the key to high-quality, durable and aesthetic window design.

Do-it-yourself installation of a plastic window sill: video instruction

Modern construction trends imply the use of the most ergonomic materials. The requirements of an ordinary buyer are as follows - the material must be light, durable and inexpensive. Previously, wood was almost universally used, but now it is considered a premium material. Instead, plastic came to him - it is more durable, cheaper and has almost limitless decorating properties.
Most often, plastic is used in metal-plastic windows, which are now installed almost everywhere. In addition to them, it is necessary to put a window sill and slopes. Each element plays an important role in everyday life, and their selection and installation must be approached with particular care.

Installation technology

Most often it turns out that the main technical purpose of these products is completely forgotten. They are usually used as a flower stand, especially large and durable options can be designed as an extension and extension of the workspace or in the office, you can even place a comfortable sofa for reading books there.

In addition to all this, the window sills with their protrusion retain the warm air rising from the batteries at a low level, which allows you to warm up the living space much better.

Immediately after installation, you need to let it stand for a couple of days, after which the installation of the window sill begins. You need to prepare the tools:

sharp construction knife;
hacksaw for metal;
sandpaper;
hammer and chisel (if any, an impact drill or puncher);
wooden or plastic pads for leveling the surface;
building level.

According to the established rule, the window sill should enter the side walls by at least 3 cm. Using the tool, it is necessary to make special recesses at the level where the surface will be located.
If a new one is installed, then the window sill can be ordered from the same manufacturer. If they are installed separately after a long period of time, or it was decided to replace the old version with a new one, then it will have to be looked for in specialized stores or made to order. To measure the product, it is best to invite a specialist - he will accurately set the parameters of the product and will be responsible for this.

It is important to make sure that after installing the metal-plastic window, the putty, mounting mortar and foam are completely dry. After that, you can begin to prepare the working surface - it should be clean, without extraneous protrusions, dust and construction debris, as even as possible. All solid protrusions are carefully knocked down with a chisel or drill, dust is removed with a broom or a construction vacuum cleaner, mounting foam is removed with a sharp knife.
Even if the finished window sill was made exactly according to the specified parameters, situations may arise when it will not become as it should in some place. To solve this problem, sandpaper and a hacksaw will come in handy - in the right places, the finished canvas is adjusted to the installed place. If it is possible to start fitting the window sill from the side of the wall, it is better to start from it, using a hammer and chisel or a strong screwdriver. As a result, the window sill should confidently fall into its intended place, not hang out in the grooves of the side walls, but also not rub too hard.

Sprinkle the prepared work surface with ordinary water using a broom or a mechanical sprayer - it will be much easier for the mounting foam to stick to moisture, which will make it much easier to work with it. This stage is very important, because. It is the mounting foam that is the main fixing material.
Three holes are intended for installation in place - two side grooves and a recess in the window itself. The last hole should accept the window sill as clearly as possible - an unsuccessful gap will be visible during the operation of the dwelling.
The most important part of the installation is setting the surface according to the level. To measure indicators, the mounting level is used. To adjust the angles of inclination, plastic or wooden plates are placed under it. The slope should be set slightly towards the room so that moisture does not linger in the groove between the horizontal surface and the window and mold and dampness do not start there.

After the correct level is set, you need to press down the new surface with something heavy, bricks wrapped in rags are ideal. They will hold the window sill when the mounting foam swells.
All empty space under it is carefully and carefully filled with mounting foam. Designs allow to stand for at least a day.
After the foam dries, its remnants are cut off with a knife - and the window sill is ready for use.

slopes

An ideal addition to the window sill will be slopes of a similar material.
This option has a number of undeniable advantages:

relatively cheap materials;
simple installation that does not require the help of specialists;
reliability and durability;
ease of maintenance.

Slope installation procedure

The slopes consist of the following elements - sandwich panel, F-profile, wooden planks and self-tapping screws. All the irregularities of the unprepared wall are hidden under the panel.
Wooden planks are stuffed on the edges of the slopes for the entire height and width of the window opening. On top of them, an F-profile is screwed onto the screws, which has special grooves for installation plastic panel.
Completion of the profile and the plastic panel occurs with the help of scissors for metal. The main task is to prevent ugly gaps.
Directly under the panel on the wall can be put mineral wool or fill the space with polystyrene foam - this will relieve drafts and significantly insulate the walls.
