How to choose plastic windows. Sliding metal-plastic structures Metal-plastic window frames

PVC windows are installed in almost every house and apartment today, and this is not surprising, because with the advent of plastic windows on the construction market, consumers have the opportunity to make their home cozy, warm, energy efficient, protected from all kinds of external factors. As soon as they do not name windows, the design of which includes a system of PVC profiles and a double-glazed window. And PVC windows, and plastic / metal-plastic systems, and just "double-glazed windows". And now, when the time comes to replace old windows with new ones, we begin to think about what, in fact, besides the name, plastic and metal-plastic window structures differ from each other. The most interesting thing is that even Internet resources (the source of all knowledge) often give incorrect information that there is only one type of PVC windows - PVC profiles reinforced with galvanized steel, so there is no difference between plastic and metal-plastic systems. This opinion is fundamentally erroneous, and ignorance of the difference between the two main types of "new generation" windows can be used by unscrupulous distributors of these products, selling to the buyer window blocks lower quality at a higher price. To prevent this from happening, it is necessary, first, to clearly know about the properties of each type of window; second, contact reliable company, whose employees will spare no time and will advise you in detail about this or that window. So, let's find out what is the difference between plastic and metal plastic windows?

Windows with plastic frame

We want to say right away that ordinary purely plastic windows in our time can be called an anachronism: despite their relatively low cost, they are not popular and are practically not used anywhere today. The design of plastic window blocks is quite simple: PVC profiles hold a double-glazed window (single or multi-chamber). Polyvinyl chloride itself is a fairly strong material, but this does not mean that it does not need additional reinforcement, which is why, over time, simple plastic profiles began to be strengthened with strips of steel. Windows with plastic elements not without drawbacks, the main negative aspects of such double-glazed windows are as follows:

• Less strength compared to metal-plastic structures.
• Shorter service life (plastic windows will last you 10-20 years).
• Low ability to withstand external factors: gusts of wind, shock, hacking attempts.
• Restrictions in terms of the shape of the future window. Using profiles without a steel frame, only standard rectangular windows of a standard size can be made.

As you can see, PVC windows have a rather limited functionality, however, they are still installed. This is done mainly by developers with large-scale glazing of new buildings. Therefore, if you have purchased an apartment in a new house, and the windows have already been installed in it, most likely they are an inexpensive plastic economy option. How to deal with such translucent structures is up to you. You can leave these windows, provided that your apartment is not located on the first or upper floors, where double-glazed windows can be subjected to very significant impacts (ball or stone hit, burglary attempt, gusts of wind and blows from tree branches).

Metal-plastic windows - the highest quality and versatility

As the name implies, metal-plastic windows have the same plastic base- profile, but reinforced in a certain way with a steel strip. Reinforcement of PVC profiles is one of the important stages in the manufacture of a window, and the quality of future products depends on its conscientious execution. That is why, when choosing windows, it is better to give preference to a reliable company that has its own production and controls the quality of each manufactured window unit. Strengthening of the PVC profile cut according to preliminary measurements is carried out using galvanized steel and is carried out taking into account the following requirements:

• The steel strip must be continuous, that is, not interrupted or perforated.
• Reinforcement of the PVC profile is carried out along the entire contour (closed steel strip) or on three sides (U-shaped).

The advantages of metal-plastic structures make them an absolutely win-win option in comparison with simple plastic windows. PVC profiles with reinforced elements can be used for the manufacture of windows of any configuration: arched, triangular, round, trapezoidal. Increased impact resistance and wind resistance makes it possible to install metal-plastic windows in high-rise buildings.

Separately, I would like to note the durability of reinforced windows: their service life is at least 40 years. That is, you can spend money on quality windows and for the next half century "forget about their existence." Agree, the purchase of metal-plastic window blocks is a very profitable investment.

Some experts argue that the soundproofing and heat-saving properties of plastic and metal-plastic windows are the same, since they depend on the double-glazed window, and not on the profile. However, practical studies prove that the energy efficiency and sound insulation of inexpensive plastic structures are still somewhat lower than in windows with reinforced profiles.

New generation plastic windows

Recently on Russian markets new plastic window blocks without reinforcing elements, made using new technologies from a high-strength composite based on fiberglass, appeared. According to their characteristics, these structures are not only not inferior, but also in some ways superior to metal-plastic windows. Here are their main advantages:

• High strength and load resistance.
• Ease of construction.
• The possibility of using composite profiles for the manufacture of windows of various shapes.
• The highest level of sound insulation and tightness, etc.

However, composite windows, whose profiles are reinforced with fiberglass during the production process, have one drawback - this is their cost. To date, the price of a composite window is much higher than the highest quality metal-plastic windows.

An important condition for creating a comfortable microclimate in a residential area is the installation of metal-plastic windows (MPO). The market is represented by a large selection of materials, different types double-glazed windows, among which metal-plastic products are popular.

What is a plastic window

Such windows consist of a profile based on polyvinyl chloride, reinforced metal frame. Products made of ordinary plastic can change geometry due to heat changes.

From the transition of the cold season to the warm expansion or narrowing of the window profile made of non-reinforced plastic, it reaches 1 cm, depending on the size, which leads to a loose fit of the sash to the frame, as well as to sagging and the appearance of cracks.

The reinforcement of the metal profile gives additional rigidity to the structure. Deformation is prevented, the likelihood of sagging of the sash and the possibility of closing the window profile is reduced.

Varieties of MPO by:

Type of glazing (one, two, three, four chamber).

• Glass properties (heat-preserving, impact-resistant, tinted, noise-insulating).
• Sash varieties.

Windows are one, two, three and four chamber. The first option is considered the simplest, consisting of two sheets of glass and a void - a cavity between them 14-32 mm thick. This type is obsolete, so it is rarely used in residential areas.

When a window structure consists of two chambers, this means the presence of three glasses, two air chambers between them. The mounting depth is 30-58 mm, which greatly reduces the level of external noise. Double-glazed windows are sufficient for the local climate with thermal insulation characteristics.

Three-chamber double-glazed windows are less commonly used due to their cost and large mass. This option is suitable for installation in particularly noisy, industrial areas or near railway crossings, stations. Also, this glazing option will better retain heat indoors in cold climates, for example, for residents of the North.

The design of glasses from four chambers and above is not often used, because according to the main criteria for heat and noise absorption, they do not differ from three-chamber counterparts. According to the properties of glass, windows are: heat-retaining, tinted, shock-resistant, noise-insulating.

Heat-saving, keeping heat in the room are based on metallized spraying. It conducts visible rays but blocks infrared radiation. With good transparency through such glazing, heat does not leave the apartment in winter, and also does not come from the street in summer.

Glass tinting is the addition of pigments at the production stage to achieve different shades double-glazed window. Impact resistant made from tempered glass(triplex) based on several interconnected sheets. These products are durable and safe. When damaged, the fragments do not crumble, but linger, stick to a special polymer film.

To ensure a high degree of sound insulation, the distance between the chamber glasses is different. This characteristic dampens vibrational waves, and also reduces resonance. Other technological solutions are used - the chambers are filled with inert gases, the glass is covered with a film.

Sashes are deaf, folding, rotary or tilt-and-turn. A blind fixed structure in a living room is mounted along with opening doors. The folding version is used for glazing attics, verandas or for the purpose of safe ventilation during panoramic version balcony. The hinged sash opens more often inward, less often outward, provides a large air flow, and is easy to clean. The tilt-and-turn version combines the advantages of the two types of sashes, therefore it is considered the optimal, more convenient design.

In addition to the basic parameters, metal-plastic windows come in different colors and shapes. In addition to standard rectangular, square, round, trapezoidal, triangular and other shapes are ordered. Different shades are chosen, and it can also be laminated with a durable film, for example, under the texture of wood. Fans of originality and everything unusual can order stained-glass windows, with the help of images of which real works of art arise.

Construction of a metal-plastic window

The design is standard, the sealed element is a double-glazed window consisting of several glasses, the distance between which is filled with air or an inert gas. The fixed part is the frame - this is a frame mounted in the window opening of the room. The sash is the opening part. Windows are glued along the perimeter by the manufacturer with special silicone inserts that perform a noise-absorbing function. Locks, hinges, handles define functionality window construction and opening systems.

Manufacturers of metal-plastic windows

With the increase in demand for residential glazing, the number of manufacturers has increased dramatically. But not all organizations comply with the conditions, so window structures can function differently.

A metal-plastic window frame is a prefabricated structure, determined by the quality of the components from which the window is assembled.

It is better to choose a manufacturer who does not seek to earn money, but works conscientiously, values ​​​​his reputation. Manufacturers known all over the world, as well as functioning for decades, are a guarantee of quality.

Metal-plastic window: checking windows before installation

The client during the delivery of windows to installation work must make a visual inspection of each product. Attention is drawn to appearance- the integrity of the window, as well as the correspondence and uniformity of color. Chips, dents, scratches are unacceptable. The seams must be clean, stripped. It also swings double glazing. There must be no moisture or condensation effect in the middle of the double-glazed window. The presence of screws indicates reinforcement.

Installation quality control

After installation, the client checks the reliability of the frame fasteners. The opening window should not dangle, deviate or vibrate. The sash must fit evenly across the width of the frame, without deviations. Otherwise, drafts cannot be avoided, even if the other test criteria have been met.

It is important to check the operation of the fittings. To do this, open or close the window several times, checking the softness. If you have any comments, you need to ask the master to adjust or repair.

Caring for a metal-plastic window

Like any product, the window needs constant, delicate care. Twice a year, the fittings need to be lubricated, for washing use soap solutions or special means. Powdered products violate the structure of the plastic, injure the surface. While washing windows, rubber gaskets - heaters are gently wiped.

What to be guided by when choosing metal-plastic windows?

The market is replete with a large selection of manufacturers, but for the right choice, a number of factors are taken into account. For example, the features of the room, location are taken into account. Single-chamber double-glazed windows are suitable for similar, warehouse or cold balcony glazing. For apartments, houses and other residential premises, two, three-chamber windows are suitable.

For location on the first floors, protection is installed on the fittings, as well as impact-resistant glass. It is possible to install glasses with a special sun protection coating if the room is located on a high floor, not blocked by a neighboring building for overlapping sunlight. When in the building high humidity, it is desirable to install built-in ventilation valves in double-glazed windows.

What is the basis for design choice?

The prefabricated structure represents each element separately. For example, ferrous metal is most susceptible to rust, corrosion and is used in cheap versions. A quality product consists of a galvanized frame that is resistant to moisture.

The sash with frame must be reinforced throughout the frame for rigidity, and not in places. The more glass, the better properties keeping heat in the room and soundproofing. The quality of the fittings (hinges, closing locks or devices affect the properties and duration of use).

What PVC windows are by design?

A metal-plastic profile is reinforced PVC, from which a supporting frame is created - a frame and sashes. The main characteristics of the profile: heat transfer, profile width, number of chambers. The last variety is a partition inside the profile, each chamber has its own purpose.

Types of double-glazed windows:

• energy saving. The inner glass is coated with silver atoms to reduce heat loss.

• tinted.

• impact resistant.

A popular profile is three-section. One part gives rigidity, the other produces an outflow of condensate, and the third is needed to fasten the fittings. There are 4 and 6 chamber sections. Their number affects the thermal conductivity of the frame. A double-glazed window is called several glasses, united among themselves by chambers from the air. Glasses can also have different thicknesses. The thicker the glass, the better the insulation. Firms: Rehau, Veka, KBE, as well as Siegenia-Aubi fittings.

Rehau in Russia has its own production, which allows to reduce the cost of goods. Offered to clients wide choose profiles, double-glazed models. Each option is distinguished by high technical parameters, quality, but prices may be higher than those of competitors.

Next famous company all over the world is Veka- Veka. Profile made of metal-plastic is focused on preservation comfortable temperature in the apartment. Products of this manufacturer are distinguished by high strength, reliability, and the high cost justifies the quality.

A responsible, conscientious company must have a certificate that is updated annually. A passport is issued for each window, as well as a warranty card.

The main parameters of popular window profiles

For the correct choice of profile, compare technical specifications. During the installation of Rehau windows, the profile width is important - 60-150mm. The wider the profile, the warmer it is. The thickness of the double-glazed window, the number of cameras directly affects the main functions. Veka windows offer the consumer profiles with a width of 58-104 mm.

Choice according to the characteristics of the premises

When ordering windows from a specialized company, the client pays attention to the use quality materials, parts, observe the technique of connection, seams, and the level of skill of the installers must be high.

Main selection factors:

• Decent production capacity of the company.
• Activity certification.
• Positive reviews.
• Long period of warranty service.

When ordering, they are determined with the type, size of sections, depending on the glazing area, purpose. The number and location of the tilt-and-turn sashes should provide access to all external surfaces of adjacent blind sections.

Double-glazed windows must be multi-chamber - at least three chambers for residential premises. The locking protection must work clearly. It is important to choose a conscientious, honest manufacturer. Don't skimp on supplies or parts. The high cost of the purchase will pay off in the future with cost savings.

Inventor of PVC material

The history of PVC windows is not so old, but enter our everyday life they succeeded thoroughly. Now we see metal-plastic windows everywhere both in luxury cottages and in shopping malls, and in ordinary apartment buildings. Because they are of excellent quality, practical and durable at a low cost.

PVC (polyvinyl chloride) from which modern metal-plastic structures was obtained by the chemist Regnald in the 19th century. But only a whole century later, in the 50s of the last century, mass production of metal-plastic windows was established and launched. In the 60s, metal profiles began to be added to the design, for greater reliability.

The first who began the production and installation of such metal-plastic structures were the Germans. For the Germans, this was a forced measure, after the war, in the absence of a large turnover Money, it was necessary to restore the destroyed state. Looking for cheap building materials, then PVC came to their aid. At first, the first consumers treated this new product with caution, but high strength, good sound insulation and resistance to changes in weather conditions quickly and reliably strengthened this technology not only in the German market, but also distributed around the world.

How to choose plastic windows

The choice of a metal-plastic window must be approached very responsibly. A properly selected window will serve you for a long time and reliably, besides, it will save your money. Malok knows that by installing a metal-plastic window, the temperature in the room automatically rises by 3 degrees. This is mainly due to the tightness of the window.

When choosing, consider:

• The room where the window will be.
• Characteristics of the PVC profile.
• Double glazing.
• Accessories.
• Additional details.
• The room where the window will be

This item is more focused on saving money. For example, when installing small window in an unheated garage, we do not need a thick PVC profile, with good reinforcement, expensive fittings and double-glazed windows. While in a residential area, all these characteristics are best observed to create a dense isolation of the room from the external environment. Also pay Special attention when choosing windows for a balcony.

Consider whether it will be just glazing, or if you took the battery out to the balcony and want to keep it warm. If this is just glazing, then it assumes that there will be another window between the balcony and the room. In this case, the balcony-room window should not have super strong characteristics, like an ordinary one that opens directly onto the street, because there will be an additional window between them. air bag, the width of the balcony.

Characteristics of PVC profile

PVC profile - provides thermal insulation, noise insulation, reliability, strength and durability of the metal-plastic construction. At first glance, all profiles are the same. This is wrong! The difference can be seen by cutting the profile and looking inside. Or feel after several months of use, when the structures begin to repaint, lose their geometry and cracks begin to form in them.

There are three quality classes for profiles:

• CLASS A; The outer wall is more than 2.8 mm. inner walls more than 2.5 mm. Such configurations for frames are considered optimal and are recommended for installation in residential premises.
• CLASS B; The outer wall is more than 2.5 mm. internal more than 2.0 mm. Configuration data window PVC frames retain heat much worse and, according to studies, are 15% more fragile than class 1 frames.
• CLASS C; Any metal-plastic structures that do not fit the characteristics of class A and B.

*there is also a so-called "objective" profile, outwardly such a window is no different from the usual one. The only difference you can see upon purchase is the "object" sticker on the window frame. Such frames do not retain heat and are very easily deformed; they are installed only in non-residential premises. Some unscrupulous sellers sell such frames under the guise of ordinary ones, so be careful.

Profile uniformity

The evenness, smoothness and uniformity of the plastic speaks of its quality. By the way, in order not to be deceived, and not to buy a fake at the price of branded windows. Pay attention to the label inside window frames. There should be a label trademark and a bunch of numbers indicating the month, date, year of production, the work team.

Profile width

There are 3 options for choosing a profile in width:

Wall thickness

There are many wall thickness configurations available from different vendors. Optimal for residential premises is the thickness of the outer wall from 2.5 to 3.0 mm.

Number of cameras

Here there is a correlation from the width of the profile. Profile 58 mm wide. can have a maximum of 3 cameras. 70mm can have three, four or even five air chambers. But in reality, when jumping into one chamber, for example, between a three or four chamber frame, you will not feel the difference. And 90 mm. The norm for such a PVC window frame is 6 air chambers.

double glazing

In fact, there are two types of double-glazed windows:

• single-chamber - 2 glasses between them air space;
• two-chamber - 3 panes, air spaces between the first and second, second and third panes.

If there is one glass, then it will no longer be called a double-glazed window. More than three glasses in one double-glazed window is inappropriate to use from the point of view of physics, optics and mechanics.

There are double-glazed windows with a thickness of 14 to 44 mm. and even more. Also, it is possible to drive gases (argon or krypton) into the chambers between the windows to increase the energy-saving properties of double-glazed windows, (sulfur hexafluoride) to increase noise-insulating properties. Also interesting is the fact of the ideal distance between the panes. It has already been calculated and ranges from 10 to 16mm. It is this distance that is most effective for thermal insulation properties double-glazed windows, with the lowest rate of convective heat transfer.

accessories

This item does not limit you in choosing according to clear criteria for your premises. Everything depends only on the amount of finance that you agree to spend on fittings. We recommend that you buy high-quality and expensive accessories, as they will last for decades. You do not have to spend additional money and time on troubleshooting. To buy such fittings, we recommend contacting large construction or specialized stores, and purchasing fittings from well-known brands.

Additional details

Additional details are a window sill and a mesh on the window (if necessary). There are no exact criteria according to which it is necessary to be guided by the choice. And we mentioned this point only so that you do not forget about these little things and do not spend extra time on a second visit to the store.

Additional element - closer

PVC windows dimensions

In order to roughly calculate the cost of metal-plastic windows, you need to correctly measure the size of the window (including the balcony), you need to measure the width of the opening, then fix the height from the window sill to the upper slope, then select the preliminary shape of the window (i.e. determine: single-leaf, double-leaf, tricuspid, T-shaped, etc.). Determine the opening (in one direction, in two and the presence of the function of opening for ventilation) and the type of double-glazed window. Do not be sad if your calculation of PVC windows turns out to be inaccurate as a result, because you are not an expert in measuring windows correctly! Write down all your measurements and notes on paper, for greater accuracy, it is best to draw a drawing of each window with its dimensions. When framing, you need to consider whether you have external slopes so that the frame and glass package do not sink so that you begin to see the slope cement. Need to consider inner size and the outer dimension to understand what gaps are formed between the frame and the wall

How to calculate a metal-plastic window:
1. Width of the window opening
2. Left wall
3. Right wall
4. Distance from window to pipe
5. Distance from ceiling to window
6. Window height
7. Window sill height
8. Departure of the window sill

Metal-plastic windows installation or installation

Self-installation of metal-plastic windows does not constitute great work. To do this, we need: mounting foam, wooden blocks (for fixing the window in the window opening), a hammer, level, spatula, putty.

First, we pull out the old window from the window opening, insert a new one there pvc frame without glass. We fix it with the help of pre-prepared blocks and align it according to the level, then we insert a double-glazed window into the opening, again we measure the level, if it has gone astray. After making all the measurements, the gap between the PVC and the window opening can be filled mounting foam. Be careful with mounting foam, if it gets on any unwanted surfaces, it is very difficult to erase and wash off. If, nevertheless, the foam got outside the opening, then it should be wiped off immediately before it hardens. After the foam dries, and this is about a day. We take out wooden blocks, fill the cracks that have formed with foam, wait for complete drying. We cut off the protrusion of the foam with a clerical knife flush with the window. Using putty, we hide the ugly appearance of the foam.

The window sill, if you also purchased it, can also be planted on the foam on the old one already installed. When doing this, do not forget to measure the level.

Window wiping

Over time, the window sashes are lowered, and the friction of the frame begins when opening and closing. There are two ways to solve this problem. Both are solved with a set of hexagons.

Option 1

With the window open, find the adjusting screw, classically it is located at the top of the sash. Turn it in the right direction with a hexagon, clockwise, raises the window, counterclockwise, lowers it. If that doesn't work, move on to the second option.

Option 2

Remove plastic protection from the bottom hinge, using a hexagon, turning the screw clockwise or counterclockwise, adjust the window.

Plastic windows blow. A clear draft near the window

This phenomenon occurs due to loose pressing of the window to the window frame. At the end of each opening window, there are so-called "eccentrics". "Eccentric" is a bolt that is capable of movement and regulates the density of pressing the window. Turn this element to the left / right, each time checking the density of pressing, in this way you will find best option pressing. For example, in the summer you can make a weak pressing of the window to the window frame, to get more air into the room during your absence, with the windows closed.

Crackling and other strange noises in the handle

A sign of a future breakdown for the handle, unfortunately, for the most part, the handles cannot be repaired. And if it fails, the only way out is a replacement.

Not everyone knows that when we talk about metal-plastic structures, we are talking about regular windows PVC. And they are called so because the plastic contains steel reinforcement. The metal-plastic profile can have various shapes and sizes, that is, it is a universal element that is used in a variety of conditions.

Features of plastic windows

Such designs are much more widespread than wooden or aluminum counterparts. The main material is PVC. This is a type of synthetic polymer known for its high consumer properties. Similar products are completely harmless to humans, resistant to environmental influences and corrosion.

Inside plastic profile there is a metal frame, which is the basis of the entire structure. Finished on the outside plastic material. Like other window counterparts, this type has a frame, sashes, double-glazed windows. The kit also includes a metal braid, hinges and locking elements.

Air chambers are located inside the metal-plastic window. Due to the high tightness, these structures are distinguished by a high level of noise and heat insulation. It is safe to say that the plastic profile will protect your house from drafts and reduce heating costs.

Maintenance of such products is practically minimal. If you decide to install plastic windows, then you no longer have to treat the frame with varnishes and paints, as well as glue the sashes to insulate the windows for the winter. The material does not peel off and does not need to be repainted, and the complete tightness does not let through cold air inside the premises. It is also very easy to regulate such products. The modern window industry offers a wide variety of ventilation options. It is enough to turn the handle at a certain angle to let air into the room.

Why is it even better to put a PVC frame? It is difficult to ignite and does not allow the fire to spread further. That is, such products are fireproof, unlike wooden counterparts. good profile strong enough and durable enough, so it can be installed in both country houses, and on the top floors of skyscrapers. Of great importance is the choice of accessories. The ease of use and service life of the entire product depend on these elements. The set of fittings includes handles, hinges and their supports, as well as other accessories. All of them are responsible for adjusting the sashes, so you can’t save on such trifles.

How to install a metal-plastic window?

If you decide to install a double-glazed window yourself, you should understand that choosing a quality design is only 50% of success. The remaining 50% of durability, comfort and warmth depends on proper installation. Therefore, we strongly recommend entrusting such installation in a house or apartment to purely professionals.

To correctly set such a profile, you must clearly follow the instructions, which include a strict sequence of steps:

1. Aperture lock.
2. Dismantling of the old product.
3. Opening preparation.
4. Fixing the window in the opening.
5. Work with assembly seams.
6. Drain device.
7. Installation of shutters, double-glazed windows.
8. Installation of slopes.
9. Checking the tightness of the entire structure and the performance of the fittings.

Why is it undesirable to install metal-plastic windows with your own hands? Measurement errors, a previously uncleaned surface, improper fastening of the sashes, failure to use a level during installation - all these and other factors will nullify the work, including the installation of a window structure. And only experienced professionals can know about such nuances.

How to properly adjust windows?

As mentioned above, it is worth choosing a plastic window, if only because it does not need to be additionally insulated. But when the season changes, it is necessary to adjust the window for winter or summer by setting one or another sash mode. For this, it is not necessary to contact specialists. It is quite possible to adjust by hand. How to do it? Read on.

Why do you need to adjust the frame?

When winter replaces summer or vice versa, it is important to adjust the sashes to a certain position. Initially, the clamp is in a neutral state. However, leaving it in this form, there may be not too good consequences:

• drafts even when correct adjustment;
• heat loss from the apartment in winter, if the summer mode is set;
• the constant presence of the valves in summer mode due to strong pressure quickly disables the seal;
• violation of the microclimate in the room.

Moreover, an incorrectly set mode can lead to the need to do repairs yourself or with the help of a wizard. But in any case, this is unnecessary trouble and waste.

In order to put the structure in one mode or another, you must first look at the trunnions (eccentrics) that are located on the side of the sash. If you saw holes for a screwdriver or a hexagon, or an oval-shaped trunnion, then such a double-glazed window can be adjusted in summer or winter mode. But it is better to clarify this nuance in the company that carried out the sale and installation. To activate the desired mode, simply turn the pins on the sash with a tool to a certain position.

How to choose the right plastic windows?

Before purchasing similar designs for your home, it is important to understand that you are making a purchase for decades. Therefore, it is better to choose immediately high-quality and reliable model by ordering the installation in a serious company. Which is better PVC products? It all depends on various factors:

• type of house and living conditions;
• your aesthetic preferences;
• financial opportunities.

Modern window production offers many options. Each of them is distinguished by the quality of the profile and the reliability of the fittings. To avoid window repairs in the future, give preference to qualified specialists and carefully operate the product. For all questions of selection, repair and maintenance, you can contact our company!

Modern high-quality windows are one of the conditions for creating a comfortable microclimate in a house or apartment. There are many varieties of double-glazed windows on the market, among which metal-plastic products are becoming increasingly popular.

What it is

Metal-plastic windows- these are windows made of PVC profile reinforced with a metal frame. Products from a conventional plastic profile can change their geometry as a result of thermal changes. When the seasons change, the expansion and subsequent narrowing of a non-reinforced plastic window can reach 1 cm, depending on overall dimensions, which leads to a loose fit of the sash to the frame and sagging, the appearance of cracks.

Reinforcement with a metal profile gives additional rigidity to the structure, prevents deformation and significantly reduces the likelihood that the sash will sag and stop closing.

The metal-plastic window has a standard general design:

• double-glazed window - a sealed element consisting of several glasses, the distance between which is filled with air or inert gases;
• frame - a fixed part mounted in a window opening;
• sash - opening part;
• - silicone gaskets that perform soundproofing functions; installed along the edges of the double-glazed window;
• (locks, hinges, handles) - determines the functionality of the window structure and the opening system.

Types of metal-plastic windows

By type of double-glazed windows:

Glass properties:

By type of shutters:

• Deaf. Fixed structure, it is advisable to install in residential premises in combination with opening doors.
• Folding. Used for skylights or safe ventilation with panoramic balcony glazing.
• Swivel. Opens inwards (rarely - outwards), provides a powerful flow of air into the room, makes it easy to wash outer surface this and neighboring valves.
• Swing-out. Combines the advantages of swing and flap doors and is the most convenient design.

In addition to the main parameters, metal-plastic windows differ in shape and color. In addition to the usual rectangular ones, round, trapezoidal, triangular and other exotic shapes can be made to order.

Instead of the standard white color the profile is painted in more than 10 colors or laminated with a durable film that imitates wood textures.
The original design technique is stained glass, with the help of which window opening you can create a real work of art.

Choice factors

The market offers the widest range. To do right choice, several factors must be taken into account.

Room features

Appointment. Single-chamber double-glazed windows do not retain heat well and are suitable for utility and storage rooms, cold balconies. For residential premises in Russian climatic conditions, 2-3-chamber double-glazed windows are required.

Location. For apartments on the first floors, it is recommended to immediately install protective locking fittings and impact-resistant glass. Especially strong armored products are produced for offices and shops.

The degree of illumination. If the window is located on the sunny side and on a high floor, not obstructed by neighboring buildings, it is advisable to provide glass with a special sun protection coating or film.

Humidity. In case of poor ventilation of the room, double-glazed windows with built-in valves are installed, which will allow maintaining an optimal microclimate without frequently opening windows.

Which metal-plastic double-glazed windows are better

Metal-plastic window- a prefabricated structure, each element of which affects the overall quality level of the entire product:

• Type of reinforcing metal. Ferrous metal is highly susceptible to corrosion and is used in budget models. In high-quality products, a galvanized frame resistant to moisture is used.
• reinforcement quality. It is important that the sash and frame are reinforced around the entire perimeter, and not in places - then the structure will receive a uniform improved rigidity.
• The number of glasses. The more of them, the better the heat and sound insulation properties of the window.
• Hardware quality. Hinges and locking devices directly affect the consumer properties and service life of a metal-plastic window. Trusted brands (Maco, Roto, Vorne) should be preferred.

How to choose

In the production of metal-plastic windows, in addition to using high-quality materials and parts, it is equally important to observe the technology of joints and seams, and the qualifications of installers must be high level. Therefore, when choosing windows, you should definitely pay attention to the presence of:

• decent production capacity at the manufacturer;
• quality certificates for components (profile, fittings);
• positive reputation of the dealer-seller;
• long warranty period.

When ordering you need:

• Decide on the type and size of sections, depending on the area of ​​​​glazing and the purpose of the room. The number and location of the tilt-and-turn doors should be such as to provide convenient access to all external surfaces of adjacent blind sections.
• Choose double-glazed windows with the optimal number of chambers - the degree of thermal insulation of the room will depend on this.
• Provide locking and protective fittings.

The advantages of metal-plastic windows are obvious. Some of their important characteristics (for example, the presence and type of a reinforcing frame) cannot be verified upon purchase, so it is important to choose a trusted and conscientious manufacturer. You should not save on the quality of components and parts - a more expensive purchase will pay off in the future and save owners from additional hassle and costs.
