What kind of quality window sill? How to choose a plastic window sill: basic parameters. Main brands in the plastic window sills market

Just 20 years ago, most ordinary people did not wonder what kind of window sills were installed in their apartment. Whatever the builders installed, that’s how they stand. Often these were reinforced concrete slabs with poorly processed edges (at best - wood concrete). Over time, thrifty tenants replaced such window sills with wooden ones, filling the voids with foam rubber, or, at worst, with rags, and sealing the cracks with the same cement-sand mortar.

Then came the era metal plastic windows. And along with it came plastic window sills, polyurethane foam, and gypsum plaster compounds for putty. Yes, yes, a plastic window sill has become an almost uncontested addition to the same window. In most cases, options were not even considered, and indeed were not offered either.

Or they were almost never offered. Because at the same time, we were not close, but we still became acquainted with artificial stone countertops and learned technologies for producing polymer concrete. Yes and a natural stone in slabs (English slab - plate, plate, big piece) has become more affordable with the arrival of modern stone processing equipment at our production facilities. Today it is quite realistic to talk about the presence of choice on the market of window sills or materials for window sills. We will try to comprehensively consider this issue, analyzing all the pros and cons of the various options.

Types of window sills and their features - what to make a window sill from?

Here we immediately answer the most frequently asked question on this topic: which window sills are best for plastic windows. For plastic windows, plastic window sills are better.

• Firstly, homogeneous materials have the same technical characteristics and chemical composition, which means they have the same expansion coefficients, thermal conductivity and other properties.
• Secondly, the same chemicals and materials are used for their maintenance and repair, and their service life is approximately the same.
• Thirdly, they simply look organic in combination with each other.

There are still arguments in defense of this postulate, but even these are enough to come to this conclusion.

But, one more thing: these are the window sills that are better “for windows.” But for a person, for a consumer, this is not a fact. It is definitely better for the user that the window sill meets the requirements that he puts forward. But plastic window sills cannot always meet them: many of them cannot withstand the weight of a large flower pot, you cannot place a hot frying pan on them, they scratch very easily, etc. Although, if we talk about aesthetics and design, then in this regard they are able to cope with the highest requirements.

Moreover, they are in absolute compliance with the color and texture base of the lamination of metal-plastic windows.

• Plastic window sills (PVC window sills)– the most common installation option. Cost of 1 p.m. 100 mm of metal-plastic window sill today ranges from 80 to 540 rubles/m.p. Agree: there is plenty to choose from. Both the price and quality of plastic window sills vary radically. We would advise focusing on products with a price of 250 rubles/m.p. 150 mm window sill.

What does our industry offer today besides plastic for window sills?

• Composite window sills– made by extrusion from a wood-polymer composite (wood shavings + approximately 1/3 polymer).

Compared to a purely plastic window sill, a composite one is distinguished by greater hardness, bending strength, durability and a slightly higher price;

• Wooden solid– rather a way to be original, given physical characteristics tree. In combination with it, it is still better to use wooden windows or laminated metal-plastic ones, but remember that the requirements for installing such a window are stricter.

The appearance of abundant condensation on a window with such a window sill can lead to very unpleasant consequences.

• Wooden laminated- somewhat more physically stable than its solid wood counterpart, but not by much.

Glued window sills also come in this design, using plywood or MDF inserts, veneered.

The cost of wooden and wooden glued window sills today ranges (for pine) from 25 to 28 thousand rubles/cub.m. Beech or oak will cost approximately 4,500 rubles. but already per sq.m. with a thickness of 40 mm.

• With a base made of fiberboard or MDF, laminated or veneered.

Often such window sills are installed in residential premises. But in kitchens they can be used to create combined countertops (window sill - table, window sill - working surface, window sill - bedside table, etc.).

In these cases, panels with thick plastic lamination with improved consumer characteristics are used. At a price of 3 to 5 thousand rubles/sq.m. this is a fairly affordable option

• Stone– often granite (harder) or marble (softer). Made from slabs of natural stone. It is possible to use other types of stone, but extremely rarely, when solving special design problems and having practically unlimited financial resources, due to the high cost of the material.

The cost of such products made of marble or granite will range from 10 to 40 thousand rubles/sq.m. depending on the thickness (20 - 30 mm), type, quality of the stone and types of its processing (cleanliness, gloss, chamfers, etc.). With other stones the calculation is individual.

• Window sills made of artificial stone– a worthy alternative to all-stone window sills. Often only a specialist can notice the differences. Technical characteristics vary greatly depending on the type of polymer used in manufacturing. You can get a window sill with specified characteristics (chemical resistant, heat resistant, etc.).

You can create the most beautiful options a stone with an appearance very close to real, but not found in nature.

An option for a window sill is a countertop in the kitchen, most often made of artificial stone. In this case, you can get the most interesting combination of price and quality.

The cost of window sills and countertops made of artificial stone is very individual and depends primarily on the polymer and filler used, as well as on the thickness of the coating layer and the thickness of the fiberboard substrate. The weighted average today for central Russia will be the cost of 1 sq.m. countertops made of artificial stone at 20 - 22 thousand rubles.

As you can see, there are a great many design options, both in terms of types of materials, and in terms of characteristics and cost, but the next section of the article will help to competently balance our desires and capabilities with our needs.

Windows are crying, or how to get rid of condensation

Even if you installed the new window absolutely correctly, and first of all this refers to its positioning in the wall mass so that inner surface glass unit was located beyond the dew point, you need to keep in mind some other aspects. Without sufficient airflow (or heating), especially in the kitchen, bathroom, and windows, moisture may condense. The question of how a window sill can influence this process is more than appropriate, since we are placing it here.

Most housewives, when installing a window sill, insist on its maximum width, without thinking that by increasing it they radically worsen the window airflow conditions due to air convection provided by a radiator installed under the window.

What to do?

1. Refuse the width of the window sill to completely cover the radiator. Ideally, the outer edge of the window sill should reach no more than half its thickness. Moreover, even a lowered curtain will not block the convection currents.

2. Embed grilles of directed air ducts into the PVC, chipboard, MDF or wooden window sill and unfold them so that warm air flows onto the double-glazed window.

3. Install a window sill made of natural stone, which, when heated, will begin to radiate heat onto the double-glazed window.

4. Install the so-called " thermal curtain" Of course, we do not mean a blower installed at the entrance to stores and office rooms, although it will definitely cope with this task effectively. We recommend installing a PLEN (film infrared low-temperature electric heater) or a similar device into the slope, which will heat the window niche with radiant energy, creating the necessary operating conditions. It is important to remember that IR rays pass freely through the glass without heating it, so the direction of the rays should be: from the slope to the slope, from the upper slope to the window sill (or vice versa).

5. Radically insulate the external slopes and the wall of the building around the window, moving it exactly in place installed window dew point closer to outer surface walls.

Which of these is more suitable for you - choose for yourself, we will briefly talk about correct installation window sill.

We will not complicate the scheme standard installation window sill, considering some techniques unnecessary and aimed rather at the use of a particular material, lobbied by its manufacturers. Therefore, we ask everyone who has noticed these particular nuances of our instructions to think about the feasibility and, most importantly, the effect of using such materials and devices.

Let's start with what you at least need to see under the window sill if you remove it.

We would like to draw your attention to:

• the presence of 2 rows of stands under the window sill;
• absence of voids adjacent to the window and slopes;
• foamed outer edge;
• foam protection with a layer of plaster.

But what was wrong when installing this window sill was that its edge adjacent to the window was not placed under the lower edge of this very window. Let's look at the diagram:

This correct scheme installation of the window sill and it begins with carefully foaming the voids around the window, if they were not filled during installation of the window. If installation is carried out simultaneously, then we simply focus on this. It’s just that defects in window foam can be corrected when installing slopes, but in the lower part, after installing the ebb and window sill, nothing can be corrected.

1. We recommend installing L-shaped support stops. They are inexpensive, but will allow even a beginner to press the window sill tightly against the window, without a gap that will subsequently have to be filled with silicone sealant.

If there are such clamps, screwed to the stand profile at least every 15 - 20 cm, the rear row of stops need not be installed.

2. The next step is to mark the window sill and install it dry, without foam. At the same stage, the height of the front stops is selected. Ideally, it is better to use special plastic wedge stops. They can be set perfectly if the window is measured correctly. If there are none, scraps of moisture-resistant plywood will do. plastic plates different thicknesses or so on. Use wood as a last resort.

By the way, in this photo the installation is carried out using bitumen tape, which, in our opinion, is not necessary at all if all other conditions are met. Because untrimmed foam has very good waterproofing properties if isolated from UV exposure. When installing a window sill, both the first and second conditions must be fully observed. And that will be enough. We make sure to check the correct installation using a level.

3. After the window sill has been tried on and positioned, remove it, mark the installation locations of the stops, spray the installation site with water from a spray bottle (if available) for better adhesion and apply foam, as shown above.

4. We insert the window sill, snapping it into the front stops, and evenly distribute the load for at least 12 hours so that the foam does not disturb the level when expanding.

After the foam has polymerized, the load can be removed and finishing of slopes, etc. can begin. It remains for us to mention the features of installing a window sill with very thin wall, which now, with the development of energy-efficient housing construction, is increasingly becoming the norm. In this case, it would be most practical to use furniture corners - quite powerful and at the same time durable devices for attaching shelves and other things.

We can add to this that the vertical part of such a corner must be screwed to the load-bearing beams of the frame or other stable elements of the wall and can be mounted into it under drywall, but this is worth remembering before finishing interior spaces.

Dear readers, if you have any questions, please ask them using the form below. We will be glad to communicate with you;)

Which window sills to choose for PVC windows is a question that faces clients of window companies when ordering new windows. As a rule, the supplier is ready to provide several options for slopes and window sills, which differ in design, materials and price. The choice will always be based on a compromise between cost and quality, so when deciding which type of window sill is best, keep your overall budget in mind.

Choosing a window sill for a plastic window begins with materials. For the most part, suppliers offer all of the following types for plastic windows:

• window sill made of plastic (PVC);
• made of solid wood;
• from natural stone;
• made of acrylic.

Plastic window sills

Plastic models for PVC windows are most often chosen - they go well with the plastic texture of the window itself. If there is a colored film on the frame with an imitation of any texture, it is also applied to the plastic window sill.

Popularity plastic types explains not only wide choice design, but also other advantages:

• simplicity and low cost of production;
• ease of installation;
• lack of high care requirements;
• perfectly smooth surface without blemishes;
• color fastness to UV radiation (does not fade or turn yellow);
• durability;
• no need for painting.

To make the right choice, you need to know not only the advantages, but also the disadvantages. Among the disadvantages of plastic structures are low thermal stability (you cannot place hot objects on the surface, otherwise it will melt) and low maintainability (if dents, chips and cracks appear, nothing can be done). Knowing in advance what weaknesses this species has, you can be extremely careful and preserve it in its original form for many years.

You also need to know how to choose plastic models. What types of plastic structures exist? Mainly the difference lies in quality. The chambers should not be too thin; a minimum distance between the walls is encouraged - it is the structure of the chambers that is responsible for the strength of the entire structure. Press down on the display piece (if you have one) to make sure it doesn't crack or sag.

Choosing a plastic window sill is recommended for those who value practicality and do not like to clean a lot or regularly repaint. It is also suitable for lovers of bright colors and unusual textures - there is the possibility of stylizing it as stone and wood.

Wooden window sills

In second place after plastic ones in popularity are wooden models. The choice of a wooden window sill must be made according to several criteria - wood, size, thickness, color. Oak boards are the most durable, but also the most expensive. Pine and alder are cheaper, but too soft, but beech is quite suitable for such purposes. This type of wood is strong enough to resist mechanical damage, looks good, can be tinted, and is inexpensive.

What are the advantages of wooden models:

• pleasant tactile sensations, pleasure from contact with living material;
• durability;
• strength - they have a solid structure, withstand heavy weight, and can be restored if scratches, chips, or color imperfections appear;
• elegance - wooden ceilings look good in any interior;
• wide choice of colors - wood can be painted.

Let's complicate the choice a little - we'll tell you what disadvantages the material has. The first is low moisture resistance. It increases with the help of hydrophobic mixtures, but if not treated sufficiently, the tree will absorb moisture from the air. The second is care. Wooden surfaces require certain products for regular maintenance, and the coating needs to be renewed from time to time. The third is average resistance to mechanical damage (if you choose soft types of wood, you may encounter dents and scratches). And last but not least, the price is high - these types of window sills for plastic windows are quite expensive.

When choosing wood, pay attention to the class of wood (B and C are not suitable due to large quantity knots), give preference hard rocks, pay attention to flaws and chips. If you have the desire and ability to finish the surface yourself, order the installation of an untreated straight window sill without bevels or edges.

Stone window sills

The main advantage that stone window sills have is strength and durability. They are practically not subject to wear, they do not form dents from careless handling, and they do not need to be regularly coated with varnishes and paints. Consumers choose stone because of the following advantages:

• high resistance to temperatures and moisture;
• stylish and solid appearance;
• wide selection of colors and textures.

The disadvantages include heavy weight, susceptibility to chipping and low maintainability - if something breaks off, it will be difficult to return the surface to its former appearance. Such models are also expensive at all stages - production, delivery, installation. They are suitable for those who appreciate natural materials and focuses on design.

In addition to natural stone, there is also artificial stone (for example, acrylic). It is lighter, cheaper and easily repaired if damaged. The material comes in a wide variety of textures, shapes and colors. The difference can only be understood upon close examination.

Window sill in the form of a tabletop

It can be made of any material described above. His idea is to combine the window sill surface with a table to save space in the room or create additional workspace in the kitchen. In this case, the material is selected depending on how the surface will be used in the future. Natural or fake diamond, wood or plastic will look good in the room. If a sink is to be installed in a countertop near a window, it must be thick enough, durable and resistant to moisture.

Designs and textures

The consumer has a choice between matte and glossy textures. The gloss looks impressive, but dirt, dust and stains are very visible on it. The matte surface gets dirty less and is easy to clean, but loses in aesthetic characteristics.

To avoid condensation on the windows, it is important to choose the correct length/width of the board and its location relative to the radiator - if it protrudes above the radiator, condensation will appear on the windows. Design the window sill so that it does not cover the radiator, or install a ventilation grille in it for unhindered movement warm air.

We hope this material helped you understand which window sill to choose for plastic windows. By comparing all the pros and cons, you can make the best decision for your interior.

Types of window sills for plastic windows: which one is better to choose?

Often, the installation of plastic windows is accompanied by the logical question of which window sill to choose, because there are several types of them.

Let's try to understand the features of each of these materials, go through their advantages and disadvantages and find out which is the best window sill to choose for your plastic windows. Shall we begin?

Types of window sills

First of all, they are distinguished by the material from which they are made. All of them are represented on the market to one degree or another and are constantly offered by window installation companies.

So, they are:

• From PVC (plastic window sills);
• Made from solid wood;
• Made from natural stone;
• Made from artificial stone (acrylic or agglomerate).

Well, let's start with each one in detail.

Plastic window sills

Today on the modern market you can easily find plastic window sills presented to potential

This type is perhaps the most common, because there are many options for plastic window sills, both in color, texture, shape, and manufacturer.

Why are they so popular?

• Easy to install window sill;
• Do not require careful care;
• Have perfect flat surface without flaws;
• Do not fade when exposed to sunlight;
• Large selection of shapes, colors, textures;
• Durability;

However, there are a number of practical disadvantages that you should definitely consider before purchasing.

• Low heat resistance. If you place a hot object on them, this will lead to deformation or staining;
• Low maintainability. If, for some reason, dents, marks of cuts or a crack appear on the window sill, then it is almost impossible to fix it.

It is PVC window sills that are most often offered by companies that sell and install plastic windows.

Pay attention to the structure of the windowsill chambers - they should not be too thin, and there should not be a wide distance between the walls, because it is the structure of the chambers that ensures the final strength of the surface as a whole.

Don't be shy and check the strength of the window sill by pressing on it. Sooner or later you will have to stand on it to wash a window or hang a curtain and you must be sure that it does not deform under you.

In general, plastic window sills - a good choice for those who are used to not spending a lot of time on cleaning, and for those who prioritize practicality.

The question also often arises - how to choose the color of the window sill. It is worth noting that in most cases the classic white color is used, because this design is suitable for any interior. You can also choose window sills painted to resemble wood or stone, but then you should take into account the design features of the room.

Wooden window sills

Solid wood window sills will serve as an excellent addition to the interior of any room.
Yes, some breeds can be very expensive, but there are worthy alternatives. For example, beech. It is cheaper than oak, but much stronger than pine or alder.

Let's look at the advantages of such surfaces:

• Durability;
• Tactile warmth - they are very pleasant to the touch;
• Strength. Due to their solid structure, such window sills are considered much stronger than their plastic counterparts.
• Fits perfectly into the interior, looks expensive and elegant.
• The window sill can be painted in any color, also given correct form at your own request.

The disadvantages include the following:

• Conditional moisture resistance. If the window sill is made with high quality, it is initially impregnated with a hydrophobic mixture and also covered with two layers of varnish. Cheap options are varnished only once and at the slightest damage to the top layer they begin to gain moisture;
• Care. As with any wooden surfaces, it requires special attention and more or less regular care.
• Average resistance to mechanical stress. They can be quite easily left with scratches or dents (depending on the type of wood).
• Expensive. Window sills made of mahogany, oak, tropical wood - look cool, but are prohibitively expensive.

To ensure constant beautiful view such a window sill, you will need to wipe it regularly with a dry cloth and special mixtures for caring for wood.

Also, when choosing a wooden surface, you should pay attention to possible flaws, which, unfortunately, are common and can ruin the entire appearance of the window sill.

For example, select in advance better side wood so that it later becomes the front one. This is especially true for knotty textures that are encountered when making surfaces from class B and C rocks.

If you are afraid that the edges of the window sill will be damaged during installation, then you can ask the craftsmen to leave them straight (without bevels or edges), and polish them after installation.

Window sills made of natural or artificial stone.

Stone window sills have the highest strength and durability.

Of course, they have a price, because they guarantee durability and beauty for many years.

• Strong, durable;
• Heat resistant and water resistant;
• Do not fade;
• Artificial stone (especially acrylic) is easy to restore if damaged;
• Look cool and solid;
• Wide selection of colors and types of window sills on sale.

• Heavy weight. Window sills made of natural stone are very heavy, unlike artificial ones;
• Low maintainability (for natural stone);
• Susceptible to
• Very expensive (in the cost of materials, installation, repairs).

It is worth noting that artificial stone is a little easier and more practical to use than natural stone. It also has a wide variety of textures, shapes and colors. Such window sills are environmentally friendly, which cannot be said about natural stone, which must undergo a radiological examination.

Therefore, it is worth thinking carefully about which of these materials is better to choose.

Window sill-tabletop

They come from any of the materials that we have already discussed above.

The idea with a window sill-tabletop is perfect option for those who do not have very many square meters in the room.

This surface can be used as a table or workplace in the kitchen.

The advantages here are:

• Space saving
• Versatility

There are only two disadvantages:

• Such a window sill will be constantly filled with something;
• If kitchen window If you decide to install a sink with a window sill behind (or above) it, drops of water and dirt will remain on it.

Gloss or matte?

When buying a window sill, you will ultimately have a choice - matte or glossy?

From a practical point of view, caring for a matte window sill is a little easier than caring for a glossy one.

On a glossy surface, any stains are clearly visible due to the fact that the shine reflects and contrasts with a dirty surface. Such a window sill, of course, looks beautiful, but this only applies to those cases when it is well washed. The matte surface does not get dirty so quickly, so it is easier to use and care for.

Another important point. Condensation on windows is a common problem. But strangely enough, this comes from the wrong choice of the length and width of the window sill. After all, as a rule, a battery is placed under the windowsill.

If the window sill protrudes above it and “covers” it, then condensation can be seen on the windows. To prevent this from happening, it is worth making sure that the window sill does not cover the battery. But there is also Alternative option– installation of ventilation grilles on the windowsill. In the photo you can see the trajectory of the warm air.

The choice of a window sill should be taken responsibly, because negligence in this matter can cause discomfort during use, as well as unnecessary troubles for the owners. Please pay attention before purchasing Special attention not only on the description of the product or manufacturer, but also on customer reviews.

We hope our information was useful and will help you choose the ideal window sill for your apartment.

In the production of these products, the extrusion method is used - molten polyvinyl chloride is slowly squeezed into special molds, where it hardens. The use of this technology makes it possible to produce window sills that are hollow from the inside - a solid inner chamber is divided by thin vertical ribs. Thanks to this cross-sectional shape, these products have a high degree of resistance to external loads despite their low weight. The presence of internal honeycombs not only reduces the weight of products without reducing their strength, but allows the window sills to withstand bends.

Pros and cons of PVC window sills

Types of window sills

PVC window sills have approximately the same performance characteristics and dimensions, so the main differences lie in the decor. Today there are several models with a matte or glossy surface on the market:

• white;
• colored in mass (brown);
• laminated (wood-like and fantasy decors, as well as imitation of natural stone);
• with co-extruded face covering.

Window sills are most often chosen taking into account their compatibility with window profiles. However, you can consider combination options with Qunell slope systems, which you can read about on OknaTrade, floor coverings And facing material for walls, as well as furniture. A wide selection of decors allows you to choose a window sill for any interior and type window designs, including products made of aluminum and natural wood.

Modern technologies for laminating window sills make it possible to apply a film to their surface that is absolutely steam and moisture resistant.

Dimensions and weight of window sills

One square meter window sills from different manufacturers weigh on average about 7.5 kg. Also trade marks When releasing their products, they try to adhere to the same sizes:

• blade length – up to 6000 mm;
• width – from 100 to 1000 mm (step 50-100 mm);
• height – from 18 to 22 mm;
• Kapinos height is from 30 to 45 mm.

All window sills can be easily cut with a well-sharpened manual or electric cutting tool. Thanks to this, their dimensions and shape can be quickly adapted to individual needs.
Typically, for window sills with a width of up to 600 mm, the difference in size is determined by a step of 50 mm, and for models with a leaf width of 600-1000 mm - 100 mm.

How are window sills marked?

When selling window sills, the manufacturer must provide all important information about the product. This information is contained in the marking, which, according to GOST, should consist of the following items:

1. Date of manufacture of the product;
2. Type of profile structure;
3. Window sill dimensions (height, width, length);
4. The main material from which the product is made, and what additives were used in production;
5. Installation recommendations;
6. Individual features of the product;
7. Shift, batch and extruder number.

Before purchasing, it is recommended to check not only the presence of markings, but also ask the seller for quality certificates. Today, some entrepreneurs purchase extruders and use low-quality recyclable materials with impurities that are unacceptable by standards for the production of window sills. As a result, it is necessary to personally verify the quality of the purchased products.

What else do you need to purchase along with the window sill?

To perform installation according to all the rules, it is necessary to use plugs and, in some cases, connecting profiles. These elements are usually sold together with window sills and are available in white, black and Brown. If you plan to install a wide panel that protrudes far into the room, you will definitely need to buy and install ventilation grilles. Why this is needed, read on OknaTrade.

Additional attention needs to be paid to

Labeling and quality certificates are not the only things you need to pay attention to when purchasing window sills. When purchasing these products, it is recommended:

1. Give preference to products from time-tested brands;
2. Make sure there is a protective film;
3. Obtain from the seller information about the manufacturer’s warranty obligations;
4. Check the number of stiffeners - it is advisable that the distance between them does not exceed 35 mm;
5. Find out the maximum load that the product can withstand.

If window sills are ordered together with windows, then all this information must be obtained from the manager, and then checked when delivering the products to the site.

The minimum thickness of the top wall of a plastic window sill should be 3 mm, the vertical stiffeners - 1.5 mm, and the bottom wall - 2 mm.

New modification – combined plastic window sills

Some manufacturers began to mix wood filler into PVC to improve the performance characteristics of window sills. This unusual combination of materials made it possible to increase the strength of the window sills and reduce their weight. Products made from wood-polymer composites are recommended for use in buildings where increased safety and environmental friendliness are simultaneously required - in schools, kindergartens and hospitals. However, today they are increasingly used in all other facilities - residential, retail, office and production premises. Manufacturers of Moeller window sills have achieved great success in the development and manufacture of new products. They managed to create a product that has the best price-quality ratio.

A window sill is an essential part of a competent and professional opening design. Before choosing a plastic window sill, you should familiarize yourself with other types of designs. Some experts believe that it should be made of the same material as the windows. Therefore, PVC products with plastic windows installed in their homes are considered popular among consumers.

Types of products

Currently, there are various types of window sills for plastic windows, the main materials of which are:

Advantages of plastic window sills

In comparison with stone, wood and other PVC products, window sills have the following properties:

• they are resistant to moisture and corrosion, do not rot even in wet conditions;
• I have a low cost;
• resistant to action chemical solutions(hydrogen peroxide, acetone);
• easy to install due to light weight;
• differ in heat-saving characteristics due to internal division into chambers;
• do not require permanent painting;
• there is no warping or shrinkage;
• imitation of any color design;
• The thermal resistance and strength of the plastic profile is increased with the help of a special coating, after application of which the cost and weight of the products increases.

But plastic window sills also have disadvantages: insufficient strength (compared to stone and wood).

Basically, when installing plastic windows, people choose window sills made of the same material, as they are easy to use, last a long time, are affordable and quickly clean from dirt. They are inert to temperature changes, do not lose their original properties from the action of chemicals and ultraviolet radiation, and are not damaged by microorganisms and insects. Even after many years of use, plastic surfaces do not have to be treated (varnished, painted, sanded). The plastic is practically non-flammable, and the multi-chamber design of the canvas increases rigidity and strength.

The strength of the PVC window sill is ensured by the multi-chamber design

The high performance characteristics of polyvinyl chloride window sills allow them to be installed indoors and outdoors.

Selection of window sill boards and sizes

So, we have decided which window sill to choose, now we need to familiarize ourselves with the recommendations for purchasing a better product:

• You should pay attention to certificates of compliance of the design with the requirements of the standards. This guarantees the use of high-quality raw materials in production that will be safe for health;
• you need to clarify the characteristics of the product (resistance to condensation accumulation, exposure to sunlight), the existing coating;
• Check with a specialist about the basic rules for caring for such a structure.

You can also consult and get answers to the necessary questions, get acquainted with the variety of models and choose an option that is suitable for the room and will be combined with the overall interior.

The base consists of a plastic panel with walls whose thickness is 1.5-3 mm. Inside there are stiffening ribs responsible for the mechanical strength of the board. The greater the number of ribs, the higher the quality of the product and resistance to loads without deformation..

Window sill width dimensions

All plastic structures for loggias, balconies and living rooms are made to order according to individual measurements, since their dimensions in different buildings can vary up to 10 cm. The width of the surface is determined depending on the installation depth window profile, so it may change. Because of this, when ordering window products, a measurer goes to the address to determine exact measurements up to 1 mm.

To make a window sill board, you must take the correct measurements.

Plastic window sills are produced from standard boards with a length of 405-600 mm, so it is impossible to order the manufacture of a structure larger than 6 meters. The width of the products is 50-600 mm in increments of 5 cm and 60-100 cm in increments of 10 cm.

Before making the internal window sill, the specialist measures the width of the opening (between the stand profile and the edge of the wall), adds 5-10 cm (the size of the protruding part beyond the borders of the wall). The resulting figure is rounded to the nearest standard value.

For example, according to measurements, we obtained an opening width of 40 cm, add 5 cm to the indicator and get 45 cm. The use of plugs should be taken into account. After this, the cost of the product is determined.

Features of the production of plastic structures

There is no generally accepted classification of window sills by type. Conventionally, they are divided into groups (types) according to the type of coating.

The first category includes structures with a standard layer. They are mainly used in mass construction. The width of such window sills for windows can vary within the range of 5-100 cm with a gradation of sizes of 50 mm (every 5 cm the width of the products increases), and the length can be 6 m. You can individually order a design of non-standard sizes.

The second group includes canvases with an impact- and heat-resistant layer. They are usually installed in wide openings, which act as a working base. This coating is highly durable and does not leave any marks. mechanical damage. Similar properties are ensured by laminating plastic using a special film.

The customer can choose any shade of products in accordance with the shade of the window, but window sills are considered more popular white shade. Colored products differ from white ones only in shade, but not in quality. In this case, you can choose products that imitate stone surfaces (sandstone, marble) or wood species. For this, lamination and processing with an acrylic layer are used. During the lamination process, a durable material is applied to the product. plastic film, resistant to negative influences and imitating different textures (wood, stone). Russian, Ukrainian and Austrian manufacturers offer window sills with an acrylic layer, which makes the surface smooth and protected from damage.

Lamination pvc panels allows you to imitate the texture of wood or stone

You should not choose models from the budget segment, as cheap plastic turns yellow over time. More expensive options will not change the original shade for at least 10 years.

To make a plastic window sill, a special PVC profile is used, which is extruded by an extruder and treated with a laminated film on the outside. Lamination of the outer surface ensures easy maintenance and serves as protection against damage. The presence of numerous chambers in the internal space increases the thermal capacity of the structure, its rigidity, fracture strength and deflection.

The thickness of the finished product is determined by the profile size; it can be 18-22 mm. If there is a heating battery under the window, you should not make window sills whose width protrudes more than 10 cm from the edge of the wall. Otherwise, a barrier will be created to the warm air that rises from below. This will lead to condensation on the windows and cold air entering the room. If the width is larger, then the product at the bottom is reinforced with corners, and the protrusion is equipped with a ventilation grill for the free movement of warm air flows.

The choice of window sill sizes depends on the window parameters

The profile is cut with a hacksaw or saw in accordance with the specified parameters, put in place with end caps covering the internal cavities.

Installation Features

When you no longer need to think about how to choose a suitable plastic window sill, choose a stand profile ( plastic pipe with rectangular or square cross-section). It serves as the basis for the entire window structure (window sill, drain and frame), therefore it is mounted under the double-glazed window frame, to which the external ebb and flow with the internal window sill are fixed. You can also place the window in a special groove, leveling it with wooden blocks. Plastic board often placed in a horizontal plane, but sometimes with a slight slope into the room (for every 30 centimeters of board width, 3 cm of slope).

The service life of the structure depends on the correct installation of the window sill system.

The profile is fixed polyurethane foam high frost resistance with a low expansion coefficient. The entire interior space should be treated with foam, after which a heavy object (a bucket of water, books) is placed on the board so that when the foam hardens, the window sill does not rise.

Right choice and installation of plastic products will ensure high window performance.

Modern double-glazed windows for windows require the installation of appropriate accessories, and a worthy addition to them will be plastic window sills, subject to choosing a quality option.

What can you say about plastic window sills?

Every owner of a city apartment or country estate at the same time a caretaker, and a craftsman, skilled in some specific profiles of household chores (or mediocre, but diligent), and a designer. That is, as far as possible, a jack of all trades. And, looking at the cracked wooden window frames, a zealous owner will confidently say: “It’s time to change to double-glazed windows.” But what about the planks in the kitchen, which are no less cracked and have lost their aesthetic appearance? Of course, they also require replacement, but the boards would be inappropriate in this case. What is the way out? The ideal solution would be plastic window sills, and we’ll look at which ones are better next.

However, someone, considering the proposed option, will definitely remember that plastic, unlike wood, is much easier to deform, is afraid of contact with hot objects, and burns out in the sun. That is, such a window sill board may turn out to be very short-lived. Well, this is really not a myth, and a heated iron, even with short-term contact, can really leave a stain on the glossy surface. plastic surface. But, on the other hand, there are special boards for ironing, equipped with iron stands; it is better to leave a hot kettle on the stove. It is better to place flowers on the windowsill, and when combining it with a tabletop, place a laptop and books.

It would be a mistake to assume that all polyvinyl chloride window sill boards are of the same quality. If the base, as a rule, is the same for all models, then the decorative coating (lamination) can be different. There are several types of films that cover PVC window sills, and all of them have various properties, which are transferred to the processed product. In particular, there are coatings that protect against high temperatures, scratches, and fading under the influence of ultraviolet rays. Next, we will consider and compare the most common types of films.

Such different window sills made of plastic

Whichever model you choose, you will have to deal with polyvinyl chloride, or PVC for short. The difference between the products of one or another manufacturer lies only in the added plasticizers, and since the composition is not known to you, you should only be interested in quality, preferably time-tested. It is better not to buy cheap products from unknown manufacturers, since it is quite possible that such plastic window sills have an insufficient amount of plasticizer and are highly fragile.

In fact, you will have a choice of two options: with wood filler and without it, only with stiffeners. And, of course, all this will be PVC. Which type should you prefer? The first one is more expensive due to the fact that it is not produced by domestic companies and is supplied only from abroad. The second option is rigid polyvinyl chloride. And if the latter is of high quality, you will not notice any differences in strength or durability. You can even choose a model that will be resistant to high temperatures, that is, such plastic window sills will not warp under either a hot iron or a kettle.

As for stiffeners, there is a choice here too. In particular, the most common design used in the manufacture of cheap window sill boards is vertical ribs with large spaces. Reducing the number of jumpers inside the window sill allows the manufacturer to save on material, but this affects the strength properties. Higher quality models are equipped with a large number of stiffening ribs; they are more expensive, but much more reliable and durable, since they do not deform under external loads. This is how many are made plastic slopes and window sills.

The option has high strength, the stiffening ribs of which are located not vertically, but at an angle, with teeth. Connecting with each other, they form a series of triangular cells, due to which any surface deformation is completely eliminated. Strength also depends on the thickness of the window sill board, since the higher the stiffeners, the less resistant they are to loads, especially to sudden mechanical impacts. However, corner lintels are an exception, forming an extremely stable structure.

Choosing plastic window sills

So, having carefully examined the design options, let’s move on to the external coverings of the window sill boards. As already mentioned, they are divided into several classes, conditionally they can be called Economy, Classic and Elite, with the appropriate quality of the finishing film. The first option is the most common; in this case, a film of the same PVC is glued onto a base cast from polyvinyl chloride. Cheap and quite reliable, if you don’t expect resistance to scratches and hot irons from such a window sill. The coating protects from moisture, ultraviolet radiation, light impacts, and withstands the impact detergents. Maximum temperature, which such a product will withstand - a mug of hot tea or coffee. Even the ash from a cigarette can leave a lasting mark.

The second option occupies the average price position of the three listed; the coating on such models is more reliable, since it is a melamine film (CPL). These can withstand even a smoldering cigarette dropped onto the surface quite firmly and without consequences; even with significant mechanical impact, no scratches remain. What is most interesting is that this class of coating is self-extinguishing, that is, it will not provide food for fire in case of accidental direct contact with fire, for example, with a burning match falling on a windowsill. And, of course, the film is not afraid of household chemicals, especially detergents.

The Elite class includes plastic window sills coated with a film based on melamine resin, but more high level quality, which is one of the latest achievements modern technologies. The coating used is VPL or Elesgo film, produced in Germany. The first gives the window sill complete moisture and vapor resistance, resistance to any temperature fluctuations, and prolonged exposure to ultraviolet radiation. This is not to mention the exceptional resistance to mechanical damage, be it scratches or chips. The second, among other things, ensures an antistatic surface, while being an environmentally friendly material.

Any type of lamination has its own service life, which depends on the quality of the coating (it also affects the price), and it is better to choose the most durable models, without looking at the cost, or choose the golden mean.

Films covering a PVC base are given a certain color and texture even during their production. In the future, laminated window sills also become glossy or matte and acquire any color, including those imitating wood stains. By the way, such models look great with wooden frames. Elite films often have a silky surface to the touch, which indicates the quality of the coating.

IN modern design Window sills are increasingly turning from a simple frame of a window opening into a practical part of the interior, which can not only be decorated with flowers, but can also easily serve as a table or even a seat. Such a window sill greatly facilitates the process of care and maintenance of the window opening and makes the room cozy.

However, if you are carried away by arranging a stylish, functional and cozy home, you should not forget that the window sill must also meet certain technical characteristics and fulfill its responsibility such as maintaining the normal climate of the room. A good, correctly installed window sill should prevent heat loss and prevent cold air into the room from the outside. Which window sills are best to choose? You need to familiarize yourself with their types and choose the most suitable one in terms of functionality and quality.
So, there are several types of window sills, which have their own advantages and disadvantages, namely:
— concrete;
- wooden;
- plastic;
- made of MDF or chipboard.
Concrete window sills can now be found in old houses, industrial and other public buildings. When replacing old wooden windows modern windows made of PVC, they are usually replaced with new ones - wooden, plastic or MDDFSP window sills. They are very durable, strong, and can withstand a lot of weight, but they are quite cold and are not entirely suitable when you plan to make the window a resting place.
Window sills made of natural wood are very warm and comfortable. They are made from well-dried and processed by special means wood Most often it is pine or larch, but window sills of such wood species as oak, hornbeam and beech serve best; the most expensive, exclusive models are made of mahogany. Ready product can be varnished or painted. One-piece wooden window sills- quite an expensive pleasure, therefore, to reduce the cost of products, they are often made from multi-layer laminated veneer lumber.
Window sills made of chipboard and MDF, in Lately very popular due to its availability. They are produced by dry pressing at high temperatures and using synthetic resins. They are resistant to temperature changes and exposure to chemicals. household chemicals, withstand high mechanical loads. The pattern and color of such window sills can be very diverse; they can imitate natural stone or wood.
Plastic window sills in your own way appearance They don’t really stand out among other varieties of this product. Any decorative pattern (wood, marble, etc.) can be applied to the front surface of the product. Plastic window sills can be used even in high temperature and humidity.
