Metal-plastic window systems and doors are made of PVC plastic, reinforced with a metal frame, which is located in the middle of the structure. This gives the window leaf additional rigidity and strength.
Metal-plastic window design:
- Plastic frames reinforced with a metal profile;
- sashes;
- Fittings;
- double-glazed windows;
- Rubber seal.
The main component of the metal-plastic construction is a PVC profile reinforced with a reinforced metal frame. It gives rigidity to the metal-plastic structure. There are jumpers in the plastic profile, inside of which there is air. These are profile cameras. The heat of the profile depends on their number. Usually there are from 3 to 7 cameras.
The reinforcing frame can be closed or shaped like the letter "P" or "G". It is built into the most important chamber located in the center.
A double-glazed window is an element of a metal-plastic window. It consists of two or three glass surfaces, which are separated by air or gas.
The chamber consists of two glasses, with air or a special gas (argon) pumped between them. The chamber at the double-glazed window must be airtight.
Silicone seals have a soundproof function. They are installed on both sides along the edges of the double-glazed window.
Also an important factor in the durability and functionality of a metal-plastic, wooden, aluminum, plastic window or door is the fittings.
What should a high-quality metal-plastic window look like?
Before you install a metal-plastic structure, it is important to focus on some of the nuances:
- Examine the appearance of metal-plastic frames and double-glazed windows. The window must have the same, uniform color and integral structure;
- All surfaces must be flat, smooth, free of scratches and dents;
- It is important that the seams between the parts are neat, clean and even;
- Double-glazed windows must be absolutely dry inside, not sweaty, without water droplets. Glass - smooth, even without scratches;
- The reinforcement of your window can be judged by the presence of screws. This is how the reinforcement is attached to the plastic profile.
You can check whether a metal-plastic window or a door is installed with high quality by the following signs:
- The frame is securely fixed during installation. When opening the window, the sashes should not hang freely, have various deviations, or vibrate.
- When closing, the sash should fit snugly, along its entire length, against the frame, without any possible deviations. If this norm is not met, drafts will be felt.
- The fittings, when opening and closing the valves, should move smoothly, gently.
If you notice shortcomings, then try to eliminate them and adjust the operation of the metal-plastic system.
What is important to consider when choosing a manufacturer?
When choosing a manufacturer of metal-plastic structures, it is necessary to pay attention, first of all, to the company for which the reputation and quality of the installed windows are most valuable.
Such a company can sell both very expensive wooden, aluminum, plastic, metal-plastic window structures, as well as economy class models.
Such a company must have a certificate, which is issued every two years.
All components of aluminum, wooden, plastic, metal-plastic systems and doors must also have certificates and conclusions on environmental safety.
For each installed window leaf and door (metal-plastic, wood, aluminum, plastic), a technical passport with a warranty card must be issued.
If a company for the installation of wooden, aluminum, metal-plastic, plastic window systems, doors cannot provide all of the above documents, then you are at great risk by entrusting them with the installation of windows and doors in your house.
After installing really high-quality metal-plastic window systems in your country house, the costs associated with heating will drop by as much as 25%.
When replacing old wooden structures with metal-plastic ones, in just a few minutes you feel how much more comfortable, warmer, quieter it has become in the apartment.
How to care for metal-plastic window systems?
Window models made of metal-plastic require careful handling. If certain operating rules are observed, the service life of the metal-plastic structure will become much longer. Necessary:
- Lubrication of fittings twice a year. This applies to all moving parts;
- It is recommended to wash metal-plastic frames and glass with a soap solution or special products. They can be bought at a store that sells components for metal-plastic, wooden, aluminum windows. Powder detergents must not be used. They can scratch the surface, violate the integrity of the material;
- When washing, pay attention to the sealing gum. They also need to be carefully wiped so that the frames retain their tight properties.
Metal-plastic models conquer with their practicality and beauty. If you want to install new windows in your home, then there are several options: wooden, plastic, aluminum and, of course, metal-plastic. The choice is yours!
Double-leaf window with a window leaf, a transom or without
The designs and modifications of such profiles are different. Their key feature is the presence of an additional plastic bar. It increases the cost of the window block, when compared with the "deaf" counterpart. To increase the cost of construction lead to:
- filling the chambers with inert gas for greater thermal insulation,
- installation of glass of different thicknesses for maximum sound insulation,
- applying a special coating that reflects ultraviolet light.

Notes
- Typical window sizes may differ from the standard by several centimeters (up to 10 cm). So standard sizes are a rather conditional concept.
For high-quality installation of windows, it is advisable to first invite a measurer who will make measurements accurately and efficiently.
Plastic windows of non-standard sizes and shapes can only be purchased to order.
Keep in mind: the windows in the kitchen, in the living room (hall) and in the bedroom (children's room) are not the same size. Usually the kitchen window is the smallest.
Window sizes in a panel house are typical, window openings in brick houses may differ (due to shrinkage of a brick house).
Single sash windows can be
Deaf single-leaf plastic windows are designs with non-opening sashes. A blind window does not have a sash; a double-glazed window is installed directly into the window frame and is rigidly fixed with a glazing bead from the inside of the room. If necessary, the glazing bead can be easily removed to replace the double-glazed window.
Such windows are popular when the customer wants to install windows with minimal cash costs or when maximum light transmission of the window structure is required.
rotary
Pivoting single-leaf plastic windows are windows that open into the room, this option of opening a plastic window is as similar as possible to a typical, standard window opening.
The main disadvantage of this type of opening is that it is impossible to fully use the useful area of the window sill, since when you open the window sash, you have to remove everything from it.
Tilt-and-turn
Single-leaf tilt-and-turn plastic windows, the most convenient option for opening a window, in which the sash can be opened inside the room in a classic way, or can be folded down like a transom. At the same time, the folded sash does not touch the curtains, does not open inward with a strong gust of wind, you can fully use the usable area of the window sill, and most importantly, thanks to “child locks” or window handles with a lock, you can leave an open window without fear for children or for the fact that someone will open the window from the street and enter the room.
Fanlight single-leaf windows are windows that lean into the interior of the room, while the hinges are located on the lower part of the window, and the window handle is on top of the sash. If necessary, you can move the transom opening handle to the left or right side of the sash.
To wash a single-leaf fanlight window from the outside, you can remove the tilt limiter and tilt the sash to the end, gently holding it with your hands. It is better to do this operation together, so as not to break the sash when tilting.
Types of designs of double-leaf plastic windows
An important step in the repair of any residential space is glazing, and for this, windows that differ in size, design, thickness of the glass unit, design and other features can be used. A double-leaf window is a type of product that is most often used for glazing houses and apartments and combines optimal size, ease of use and moderate cost.
What is a double sash window?
This design consists of a pair of wings, one of which is deaf, and the second can be opened. This type of windows is the most popular for most buildings: glazing with their help is well suited for residential, technical and office premises equally. According to the type of opening, windows with two sashes are divided into the following types:
- Swivel type. Double-leaf plastic windows have a sash that opens by swinging inward or outward, they are distinguished by moderate cost, simplicity of design and convenience. The disadvantage of products of this kind is the limitation of space inside: due to the swing mechanism on the windowsill, it becomes difficult to keep things or plant flowers, since the sash is fully opened when airing.
- Tilt and turn models. These windows can not only swing open: the sash can be folded back to ventilate the premises. This design is more compact and convenient, the windows themselves are safer than the previous type, since the risk of pets or children falling out of the window is reduced. In the opening mode, the double-glazed window can be washed, and in the reclining position, the double-leaf plastic window allows for natural ventilation of the room. Such structures are installed in bedrooms, living rooms, private rooms, kitchens, etc.
- Sliding windows. The model implies opening the sash by moving it parallel to the fixed part. Such glazing is typical for small rooms, loggias and balconies, where it is important to save personal space as much as possible. Tilt-sliding windows (Patio)
Bifold plastic windows: main advantages
The advantages of double-leaf structures include the following properties:
- The fittings that allow you to open the sash are located inside, so the window is quite reliable.
- Washing the opening structure is much easier than a deaf double-glazed window.
- If the window has a micro-ventilation function, in the summer you can easily ensure the flow of fresh air into the room.
Plastic products are one of the most popular on the market, they are interesting due to the mass of positive qualities:
- Long service life: bi-leaf windows retain their properties for 15-25 years, which is much longer than that of wooden counterparts.
- High degree of reliability and resistance to mechanical stress, climatic phenomena (wind, precipitation, temperature changes).
- Possibility of installation in any room.
- Good indicators of sound and heat insulation, due to which, after installation in the room, maximum comfort is created.
What size should a double sash window be?
The dimensions of the structure depend on the type of building that requires glazing, the width and height of the opening. So, the size of a window with two sashes in a house of pre-revolutionary construction is 1150x1900 mm, in a Stalinist building - 1150x1950 mm, Khrushchev - 1280x1340 mm or 1490x1530 mm (series of houses 1-528). In new houses, there are more than 40 types of sizes, and when ordering, you should focus on the dimensions of the opening.
Conclusion: a PVC double-leaf window is suitable for glazing any premises, it is distinguished by maximum convenience, a modern look and a reasonable price.
What are the sizes of plastic PVC
The standard dimensions of a plastic window depend on the typical model of the house. There are a lot of standard models.
Let's look at the most common options.
- The houses of the old fund are buildings of the pre-revolutionary period. These houses are characterized by high ceilings, high windows, strong walls, large rooms.
In the houses of the old fund, there are both very wide and narrow windows.
Single-leaf window - 1150 by 1900 mm; 850 by 1150 mm.
Double window - 1150 by 1900 mm; 1300 by 2200 mm; 1500 by 1900 mm.
Three-leaf window - 2400 by 2100 mm.
- Stalinki. houses built during the reign of I.V. Stalin. Apartments in such houses are comfortable and beautiful: high ceilings, a large kitchen, spacious rooms, a separate bathroom. Such buildings were most often built of brick and covered with plaster; granite slabs were also used for cladding. The time of their creation is from the 1930s to the 1960s.
Double-leaf window - 1150 by 1950 mm; 1500 by 1900 mm.
Three-leaf - 1700 by 1900 mm.
- Khrushchev. these buildings were built from the 1950s to 1985. The houses of this type have low ceilings, poor heat and sound insulation, one- and two-room apartments. The buildings of the "Khrushchev period" have flat roofs and a simple facade.
There are several series of houses of this type. I will describe the sizes of windows of 2 series.
Series 1-507: double-leaf window - 1280 by 1340 mm.
Series 1-528: single-leaf window - 690 by 1530 mm; double-leaf - 1490 by 1530 mm; tricuspid - 2080 by 1530 mm.
- Brezhnevka- they are apartments of improved planning. "Brezhnevka" is more spacious than "Khrushchev" with a separate bathroom, garbage chute and elevator (in tall buildings). Buildings of this type are usually tall and varied (rounded, tall and wide, etc.).
Series 602 - double-leaf window - 1450 by 1210 mm; tricuspid - 2100 by 1450 mm.
Series 606 - double-leaf window - 1450 by 1410 mm; tricuspid - 1700 by 1410 mm.
A very common subtype is the "brezhnevka" series 600 - the so-called "home-ships". Tall and very long buildings look like liners. Large plastic windows are relevant here.
Three-leaf - 2380 by 1130 mm; 2380 by 1420 mm; 2690 by 1420 mm.
- Typical new buildings very varied. There are about 40 episodes here.
Standard dimensions of a plastic window in a brick house:
Double-leaf - 1490 by 1530 mm; tricuspid - 2060 by 1520 mm.
Windows in the house of the 504 series (block nine-story building with 4 apartments on the site):
Double-leaf window - 1450 by 1410 mm;
Three-leaf - 1700 by 1410 mm.
Windows in the house of series 137 (block 16-storey building with 9 apartments on the site and 2 elevators):
Double-leaf window - 1150 by 1420 mm.
Three-leaf - 1700 by 1420 mm.
Choose windows? So many offers and prices are different everywhere? Find out what should be the cost per square meter of a plastic window. My personal review of prices on the Moscow market of PVC structures.
It is not always worth choosing windows with a folding sash, sometimes it is better to look at plastic windows with a window.
Types of double-leaf windows
The window system with 2 sashes allows you to open half of the window opening, leaving the second one closed if the latter is deaf or there is a vertical impost - a plastic profile in the center of the opening. In the absence of an impost, both doors open simultaneously. Double-leaf turn-tilt window is available in different modifications. Design options:
- with one hinged, tilt-and-turn sash,
- with a pair of tilt-and-turn doors that can be unlocked.
The type of construction is chosen based on the purpose and dimensions of the room. In offices on the upper floors, it is optimal to install systems with at least one swing-out sash - it is convenient to ventilate them. Windows on the outside are usually cleaned by washers, so it is not necessary that each sash be unlocked.
In the kitchen, living room, bedroom, it is preferable to mount 1-2 unlockable doors. They can be washed outside while indoors. With them, more fresh air enters the room.
Window sizes.
The design of buildings for any purpose is carried out taking into account certain window sizes depending on the requirements of the necessary lighting of the rooms. The data of the indicator of illumination depend on the dimensions of the building, its purpose, the level of natural light and other factors. Also of great importance is the ability of the window block to transmit light into the room.
The ratio of room size and window size is determined by a generally accepted formula based on established building codes and regulations. These standards define the permissible value of the lighting coefficient in public and residential areas located north of 45 degrees and south of 60 degrees latitude. For example, if the building is located north of 60 degrees, then a factor of 1.2 must be applied. If the building is located south of 45 degrees north latitude, then the illumination should be determined using a coefficient equal to 0.75. The indicators are calculated with the condition of mandatory window washing, depending on the location of the building. So, it is necessary to clean windows in buildings located not in polluted areas of the city at least 2 times a year, and in buildings located in industrial areas, windows should be cleaned at least 4 times a year. In addition, the ability of a window opening to transmit light is affected by the number of glasses and the distance between them. Since the light rays are refracted and absorbed (if there are more than 2 glasses in the frame), the illumination in the room is significantly reduced.
During the construction of certain buildings, standard GOST for window sizes. However, in some non-standard cases, indicators may be adjusted. Depending on the type of window frame, standard window sizes are distinguished for:
- double glazing window unit;
- triple glazing window unit;
In accordance with GOST 11214-86, 23166-99, standard sizes of window openings with a height of 60 are established; 90; 120; 135; 150 and 180 cm and 60 wide; 90; 100; 120; 135; 150 and 180 cm and provided for humidity of 8-12%.
Standard window sizes consist of a set of section elements and glasses directly. For example, if a standard window unit with a width of 1320 mm, a side section of 85 mm and an average section of 130 mm, then the width of the glass in each casement must be at least 525 mm. At the same time, approximately 7.5 mm of glass should be included in the window trim on all sides. After carrying out simple calculations, it turns out that the apparent width of the glass is 510 mm. The standard size of the window opening also depends on the construction of the walls and the dimensions of the quarter. Below are tables of typical window sizes with approximate prices.
Table 1. Standard sizes of single-leaf windows.
Schematic representation of one-, two-, and three-leaf windows.
Dimensions of plastic windows
Touching upon the dimensions of pvc windows, we note that they can be very different and depend solely on the size of the opening. Moreover, taking into account modern technologies, plastic windows can be made with any size and absolutely any complexity.
To date, there is a fashionable trend to make the size of plastic windows very large, based on aesthetic considerations, such a trend looks impressive and colorful, but do not forget about practicality. The opening sash should not exceed 900 sq. mm. Nobody forbids doing it more, but such manipulations will guarantee that the structure will simply fail soon. In the case of blind sashes, we note that it is better not to neglect the advice and not to make them more than 1000 square meters. mm. this is fraught with a significant load on the double-glazed window, which contributes to its deformation.
In conclusion, we note that nothing is impossible for specialists and non-standard sizes of plastic windows have become the rule rather than the exception. Concerning questions of economy, it is expedient to underline that the standard window costs less, than its analog made under the order. But whether such savings are justified depends entirely on the size of the window opening.
Standardization of window blocks and openings
As a rule, the process of designing buildings of any type involves determining the size of window openings, taking into account the requirements for the intensity of lighting in rooms. This indicator depends on the purpose of the building, its dimensions, and the level of natural sunlight in a particular geographical point.
Equally important is the light transmission of the window block.
Based on building codes and regulations, the percentage ratio of the window opening area and the size of the room is calculated according to the generally accepted formula. The same standards give a normalized value for the illumination coefficient of public and residential premises, which are located south of 60 degrees and north of 45 degrees of latitude. All indicators should take into account mandatory glass cleaning at least twice a year for buildings that are not in polluted areas of the city, and 4 times a year for buildings with serious emissions of combustion products and similar elements. For example, if the building is located south of the generally accepted 45 degrees north latitude, then the illumination must be multiplied by a factor equal to 0.75, if the building is located north of 60 degrees, then the coefficient increases by 1.2 times. Among other things, the light transmission of the opening is affected by such indicators as the number of glasses and the distance between them. Due to the refraction of light rays and the absorption of light by more than two glasses, the illumination of the room can deteriorate significantly.
However, there are standard GOSTs for window sizes. Note that the dimensions indicated in GOST to the greatest extent correspond to the parameters of certain buildings and, if necessary, can be adjusted. Based on the types of window frames, typical window sizes are distinguished, which apply to:
- double glazed windows;
- triple glazing;
- single glazing, terrace frames.
GOST 11214-86, 23166-99 provides for a humidity of 8-12% and standard dimensions for window openings with a height of 60; 90; 120; 135; 150 and 180 cm and 60 wide; 90; 100; 120; 135; 150 and 180 cm.
The generally accepted standard sizes of windows consist of a combination of sectional elements and glass directly. For example, let's take a standard window block, the width of which is 1320 mm, the side sections are 85 mm. the average section is 130 mm, while the width of the glass in each leaf must be at least 525 mm. Moreover, 7.5 mm of glass should be included in the window trim on each side. Based on simple calculations, we conclude that the apparent width of the glass is 510 mm. Also, the standard dimensions of window openings depend on the construction of the walls and the dimensions of the quarter.
Bifold window features, benefits
A bi-fold window or door has a series of about 2-7 windows that are hinged to allow them to fold. We use double glazing technology to create more efficient window and door systems. Double-glazed windows can completely change the lighting of a room. This is due to the fact that the window is a series of glasses. Thus, by opening the window, you can effectively illuminate the room. When these windows are opened, ventilation is improved, which ensures sufficient air circulation in the building. These windows and doors create space in the room. They allow more light to enter the room, making it feel more spacious. Double glazing for windows and doors have more versatility than conventional ones. They are waterproof, so they ensure that no water enters the building when it rains.
Some may think that having hinges can provide space for water to enter the house. However, windows and doors are designed in such a way that when they are closed, there are no gaps between them to allow water to pass through. Energy efficiency is guaranteed
The double glazing technology ensures that very little heat escapes from the building, which is important in the Moscow winter. Air spaces between panes act as insulators preventing heat loss through conduction and convection
A more efficient design has a coating that provides low emissivity. The coating reflects back long-wave radiation from the surface of the building and at the same time transmits short-wave radiation from the sun.
There are several ways to open metal-plastic windows, and each of them has its drawbacks. Pivot windows can be very inconvenient to use on balconies and loggias due to the fact that the frames take up a lot of space when open. Hinged frames are better in this parameter, but you can’t put only hinged windows in the loggias - with them the loggia will be almost completely closed. Here, the best option is to use sliding windows, the metal-plastic structures of which appeared not so long ago.
Sliding windows are indispensable on balconies, in small rooms or in narrow and long rooms, such windows are also used for glazing gazebos and terraces. For windows of this type, the same PVC profile is used as for ordinary traditional windows. Double-glazed windows of the usual design are placed in sliding windows. Sliding windows for terraces and arbors differ from traditional ones only in the opening mechanism.
The mechanism of operation of tilt-and-turn windows is much more complicated than sliding ones, so sliding systems are much more reliable, they break very rarely. Therefore, their service life is longer.
When installing metal-plastic sliding windows, the number of sashes depends on the window area. The sashes can be movable, which move along the guides, and static - motionless. When choosing the design of such a window, it is necessary to ensure that with the doors open, access to all the others is free. This is the basis for choosing a sliding window design. There are no problems with cleaning windows. In sliding windows, the sashes can not be fully opened - there is a mechanism for fixing the sashes.
Do not think that if the window is easily moved from the inside, it is just as easy to move it from the outside. Metal-plastic sliding windows are equipped with a burglary protection mechanism. Usually these are complex locking systems that prevent attempts to enter from the outside.
Sliding systems have appeared relatively recently, but there are already more modern designs that combine sliding and folding doors. This is a complex mechanism that many buyers may like. It is called a metal-plastic portal.
Sliding systems can be used not only as windows, but also as doors. Especially they are now popular as interior doors. Such doors, unlike traditional ones, save a lot of space and create space. This is a good choice for cramped and small apartments. But even in large houses, such doors are very popular. An apartment or house with such doors inside looks very modern and stylish.
As for mosquito nets, they are installed on sliding windows as easily as on any others. In these windows, grids can be moved to any place in the structure.
Metal-plastic sliding structures have many advantages. For this reason, they have appealed to many buyers and are steadily conquering the window market.
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 lower quality window units at an inflated price to the buyer. To prevent this from happening, it is necessary, first, to clearly know about the properties of each type of window; secondly, contact a reliable company, whose employees will spare no time and advise you in detail about a particular 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 are 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
Metal-plastic window structures haveincreased strength and resistance
to mechanical stress due to
reinforcing steel layer
As the name implies, metal-plastic windows have the same plastic base - a 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 block. 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 high-quality windows once and “forget about their existence” for the next half century. 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
Composite metal-free profiles REHAU GENEO - expensive high-tech
window designs of the new generation
Recently, new plastic window blocks without reinforcing elements, made using new technologies from a high-strength composite based on fiberglass, have appeared on the Russian market. 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.
When glazing an apartment or a private house, the question arises as to which type of windows should be chosen. On sale are products made of aluminum, plastic, metal-plastic and other materials, and each of the systems has its positive and negative sides.
REHAU Blitz profile with metal reinforcement
In this article, we will try to give you as much information as possible about the choice between plastic and metal-plastic windows and provide useful recommendations for buying a specific option for your home.
Plastic windows and their features
For the manufacture of plastic windows, PVC is used. The material is able to provide a high level of protection against heat loss and noise penetration from the street. They are universal for the reason that they can be installed in private houses, apartments and office buildings.
Buyers choose plastic windows, focusing on strength, durability and the advantages mentioned above. This is a good mid-range option.
Metal-plastic windows and their features
The reinforcing frame is the main distinguishing feature of metal-plastic windows. It is made of metal and built into the profile - from the outside, the design is practically indistinguishable from PVC glazing.
The metal profile is distinguished by the maximum level of safety, as it is made of galvanized steel, protected from corrosion. Windows are stronger and last longer, but their weight also increases, and hence the load on the facade of the building.
Comparative analysis
The table below details the difference between metal-plastic windows and plastic ones.
| Evaluation criterion | Plastic windows | Metal-plastic windows |
| Application area | Plastic windows are universal - they can be used for glazing office buildings, residential premises, apartments, private houses | Metal-plastic windows are suitable for glazing residential premises, office buildings and industrial buildings. The main difference is the ability to use in buildings with extreme conditions, for example, on the upper floors of high-rise buildings |
| Term of use | Plastic windows will last from 20 to 30 years, depending on the type of profile and manufacturer | Metal-plastic windows are designed for more than 50 years |
| The form | The traditional option is a rectangle. Non-standard shape is also possible provided that the angle between the frames is at least 30° | The reinforcing profile allows the implementation of various alternative window shapes - from lancet to round |
| Price | Windows of the middle price segment | The price is higher than plastic windows |
For ease of decision-making, we can formulate a number of recommendations for choosing windows:
- If you are faced with the task of installing plastic windows in an opening that is experiencing a strong wind load, it is better to opt for metal-plastic windows.
- For those buyers who are on a budget, the best option would be to buy plastic windows, as they cost less.
- If you want to implement a non-standard version of glazing in your home, pay attention to metal-plastic windows - there are many more varieties of figured windows of this type.
- If you want to bet on the durability of the structure, which is especially important in the field of private construction, metal-framed windows are a solution that will surely last for half a century.
- For glazing rooms in old multi-storey buildings, a high load on the facade is undesirable, and in some cases it is completely unacceptable - the choice is clearly up to PVC systems.
A free measurer visit will finally dispel your doubts: a specialist will assess the condition of the building, give a competent recommendation on choosing the best solution and profile, and calculate the cost of the window.
