What is a metal-plastic window? Comparison of plastic and metal-plastic windows: which to choose? Metal-plastic structures

When glazing an apartment or private house, the question arises of what type of windows should be chosen. Products made from aluminum, plastic, metal-plastic and other materials are on sale, and each of the systems has its own 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 present useful recommendations on purchasing a specific option for your home.

Plastic windows and their features

PVC is used to make plastic windows. The material is capable of providing high level protection against heat loss and noise penetration from the street. They are universal because they can be installed in private houses, apartments and office buildings.

Buyers choose plastic windows, focusing on strength, durability and the above-mentioned advantages. This is a good option in the mid-price category.

Metal-plastic windows and their features

Reinforcing frame - main distinctive feature metal-plastic windows. It is made of metal and is built into the profile - from the outside, the design is practically indistinguishable from PVC glazing.

The metal profile has a maximum level of safety, as it is created from galvanized steel, protected from corrosion. Windows are stronger and last longer, but at the same time their weight increases, and therefore the load on the building’s façade.

Comparative analysis

The table below discusses in detail how metal-plastic windows differ from 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 use in glazing residential premises, office buildings and industrial buildings. The main difference is the possibility of 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 to last more than 50 years
Form	Traditional option- rectangle. Custom shape also possible provided that the angle between the frames is at least 30°	The reinforcing profile allows for the implementation of various alternative window shapes - from lancet to round
Price	Windows average price segment	The price is higher than that of plastic windows

To make your decision easier, you can formulate a number of recommendations for choosing windows:

• If you are faced with the task of installing plastic windows in an opening experiencing strong wind loads, it is better to opt for metal-plastic windows.
• For those buyers who are strapped for cash, the best option will be the purchase of plastic windows, since they cost less.
• If you want to implement in your home non-standard option glazing, pay attention to metal-plastic windows - there are many more varieties of figured windows of this type.
• If you want to rely on the durability of the structure, which is especially important in the field of private construction, windows with a metal frame are a solution that will confidently 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 completely unacceptable - the choice is clearly up to PVC systems.

A free surveyor’s visit will completely dispel your doubts: a specialist will assess the condition of the building and give a competent recommendation on the choice optimal solution and profile and calculate the cost of the window.

Double-leaf window with or without a window, transom

The designs and modifications of such profiles are different. Their key feature is the presence of an additional plastic strip. It increases the cost of the window unit when compared with its “blind” counterpart. The following lead to higher construction costs:

• filling the chambers with inert gas for greater thermal insulation,
• installation of glass of different thicknesses for maximum sound insulation,
• application of a special coating that reflects ultraviolet radiation.

Notes

1. Typical window sizes may differ from the standard by several centimeters (up to 10 cm). So standard sizes– a rather conventional concept.

For quality installation It is advisable to first invite a measurer who will take 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, living room (hall) and bedroom (children's) are not the same in size. Usually kitchen window- the smallest.

Window dimensions in panel house typical, window openings in brick houses may differ (due to shrinkage of the brick house).

Windows consisting of one sash can be

Fixed single-leaf plastic windows are structures with non-opening sashes. A fixed window does not have a sash; the double-glazed window is installed directly into the window frame and is rigidly fixed with a glazing bead from inside the room. If necessary, the bead can be easily removed to replace the glass unit.

Such windows are popular when the customer wants to install windows with minimal financial 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 opening option plastic window is as similar as possible to typical, standard window opening.

The main disadvantage of this type of opening is that you cannot fully take advantage of the usable area of ​​the window sill, since when opening the window sash you have to remove everything from it.

Tilt-rotary

Single-leaf tilt-and-turn plastic windows, the most convenient option opening a window, in which the window sash can be opened into the room in the classic way, or you can fold it back like a transom. At the same time, the folded shutter does not touch the curtains, it will not swing inward during a strong gust of wind, it can be fully used usable area window sill, and most importantly, thanks to “child locks” or window handles with a lock, you can leave open window without fear for the children or that someone will open the window from the street and enter the room.

Single-leaf transom windows are windows that tilt inside the room, with the hinges located on the lower part of the window, and the window handle on top of the sash. If necessary, you can move the transom opening handle to the left or right side of the sash.

You can wash the outside of a single-hung transom window by removing the tilt stop and tilting the sash all the way, carefully holding it with your hands. It is better to do this operation together, so as not to break the window sash when tilting.

Types of designs of double-leaf plastic windows

An important stage in the renovation of any residential premises is glazing, and for this purpose windows can be used that differ in size, design, thickness of the glass unit, design and other features. 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 reasonable cost.

What is a double-leaf plastic window?

This design consists of a pair of doors, one of which is blind, and the second can be opened. This type of window is the most popular for most buildings: glazing with their help is well suited for residential, technical and office premises equally. Based on the type of opening, windows with two sashes are divided into the following types:

• Rotary type. Double-leaf plastic windows have a sash that opens by swinging inward or outward; they are distinguished by their moderate cost, simplicity of design and convenience. The disadvantage of products of this kind is considered to be the limited space inside: due to the swing mechanism, it becomes difficult to hold things or grow flowers on the windowsill, since the sash is opened completely when ventilating. Double-hinged window
• Tilt-and-turn models. These windows can not only swing open: the sash can be tilted 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 swing-out mode, the double-glazed window can be washed, and in the tilting 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.Tilt-and-turn double-hung window
• Sliding windows. The model involves opening the sash by moving it parallel to the fixed part. This type of glazing is typical for small rooms, loggias and balconies, where it is important to save personal space as much as possible. Sloping sliding windows (Patio)

Double-leaf 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.
• It is much easier to clean an opening structure than a solid glass unit.
• If the window has a micro-ventilation function, in summer you can easily provide an influx of fresh air into the room.

Plastic products are among the most popular on the market; they are interesting due to a lot of positive qualities:

• Long service life: double-hung windows retain their properties for 15-25 years, which is much longer than their wooden counterparts.
• High degree of reliability and resistance to mechanical loads and climatic phenomena (wind, precipitation, temperature changes).
• Possibility of installation in any room.
• Good sound and heat insulation properties, due to which maximum comfort is created in the room after installation.

What size should a double-hung window be?

The dimensions of the structure depend on the type of building that requires glazing, the width and height of the opening. Thus, the size of a window with two sashes in a pre-revolutionary house is 1150x1900 mm, in Stalin - 1150x1950 mm, in Khrushchev - 1280x1340 mm or 1490x1530 mm (house series 1-528). There are more than 40 types of sizes in new houses, and when ordering, you should focus on the dimensions of the opening.

Conclusion: a double-leaf PVC window is suitable for glazing any premises, it is characterized by maximum convenience, modern look and reasonable price.

What are the sizes of plastic PVC?

The standard sizes 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 foundation are buildings of the pre-revolutionary period. These houses are characterized by high ceilings, high windows, thick walls, and large rooms.

In older houses there are both very wide and narrow windows.

Single-leaf window – 1150 by 1900 mm; 850 by 1150 mm.

Double-leaf window – 1150 by 1900 mm; 1300 by 2200 mm; 1500 by 1900 mm.

Three-leaf window – 2400 by 2100 mm.

• Stalinka. houses built during the reign of I.V. Stalin. Apartments in such houses are comfortable and beautiful: high ceilings, big kitchen, spacious rooms, 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 buildings. these buildings were built from the 1950s to 1985. Houses of this type have low ceilings, poor heat and sound insulation, single- and two-room apartments. 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 window sizes 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 also apartments with an improved layout. "Brezhnevkas" are more spacious than "Khrushchevkas" with 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 “house-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 diverse. There are about 40 episodes here.

Standard sizes of a plastic window in a brick house:

Double-leaf – 1490 by 1530 mm; tricuspid - 2060 by 1520 mm.

Windows in a building of series 504 (a nine-story block building with 4 apartments on the site):

Double-leaf window – 1450 by 1410 mm;

Three-leaf – 1700 by 1410 mm.

Windows in the building 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.

Are you choosing windows? Are there a lot of offers and prices are different everywhere? Find out what the cost should be square meter 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 take a closer look at plastic windows with a window.

Types of double-hung windows

A window system with 2 sashes allows you to open half of the window opening, leaving the second closed if the latter is blind 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. The double-hung tilt-and-turn window is available in different versions. Design options:

• with one swing, tilt and turn sash,
• with a pair of swing-out doors that can be unlocked.

The type of structure 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 door - it is convenient to ventilate them. Windows with outside washers usually clean, so it is not necessary for each door to be unlocked.

In the kitchen, living room, and bedroom, it is preferable to install 1-2 unlockable doors. They can be washed outside while indoors. They bring more fresh air into 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. These illumination indicators depend on the dimensions of the building, its purpose, the level of natural light and other factors. Also great importance has the ability of a window block to transmit light into the room.

The ratio of room size and window size determined by a generally accepted formula based on established building codes oh and the rules. These standards define permissible value lighting coefficient in public and residential premises located north of 45 degrees and south of 60 degrees latitude. For example, if the building is located north of 60 degrees, then a coefficient of 1.2 must be applied. If the building is located south of 45 degrees north latitude, then illumination should be determined using a coefficient of 0.75. The indicators are calculated subject to mandatory window cleaning depending on the location of the building. Thus, windows in buildings located not in polluted areas of the city must be cleaned at least 2 times a year, and in buildings located in industrial zones, 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. Because the light rays are refracted and absorbed (if there are more than 2 glasses in the frame), then the illumination in the room is significantly reduced.

When constructing 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:

• window unit double glazing;
• triple glazed 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 width 60; 90; 100; 120; 135; 150 and 180 cm and a humidity of 8-12% is provided.

Standard window sizes consist of a combination of cross-sectional elements and glass itself. For example, if a standard window block with a width of 1320 mm, a side section of 85 mm and a middle section of 130 mm, then the width of the glass in each sash must be at least 525 mm. In this case, approximately 7.5 mm of glass should be included in the window trim on all sides. After simple calculations it turns out that the visible width of the glass is 510 mm. The standard size of a window opening also depends on the design of the walls and the size of the quarter. Below are tables of typical window sizes with approximate prices.

Table 1. Standard sizes of single-hung windows.

Schematic representation of single-, double- and triple-hung windows.

Plastic window sizes

Touching on dimensions PVC windows, note that they can be very different and depend solely on the size of the opening. Moreover, considering modern technologies, plastic windows can be manufactured in any size and of absolutely any complexity.

Today there is fashion trend making 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 door should not be more than 900 square meters. mm. No one forbids making it larger, but such manipulations will guarantee that the structure will soon simply fail. In the case of blind sashes, we note that it is better not to neglect the advice and not make them larger than 1000 sq. m. mm. this is fraught with a significant load on the glass unit, which contributes to its deformation.

In conclusion, we note that nothing is impossible for specialists and non-standard sizes plastic windows have become the rule rather than the exception. Regarding issues of economy, it is advisable to emphasize that a standard window is cheaper than its custom-made counterpart. But whether such savings will be justified depends entirely on the size of the window opening.

Standardization of window blocks and openings

As a rule, the design process for buildings of any type involves determining the size of window openings, taking into account the requirements for the lighting intensity of the rooms. This indicator depends on the purpose of the building, its dimensions, and the level of natural sunlight in a particular geographic location.

No less important has the light transmittance of the window unit.

Based on building codes and regulations, the percentage ratio of the window area and the size of the room is calculated using the generally accepted formula. The same standards provide a standardized value for the illumination coefficient of public and residential premises, which are located south of 60 degrees and north of 45 degrees latitude. All indicators must take into account the mandatory cleaning of glass at least twice a year for buildings that are not located 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 of 0.75; if the building is located north of 60 degrees, then the factor increases by 1.2 times. Among other things, the light transmittance of the opening is influenced 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 significantly deteriorate.

However, there are standard GOSTs for window sizes. Let us note that the dimensions indicated in GOST most closely correspond to the parameters of certain buildings and, if necessary, can be adjusted. Based on the types of window frames, there are standard sizes windows that apply to:

• double glazing window units;
• triple glazing;
• single glazing, terrace frames.

GOST 11214-86, 23166-99 provides for a humidity of 8-12% and standard sizes of window openings with a height of 60; 90; 120; 135; 150 and 180 cm and width 60; 90; 100; 120; 135; 150 and 180 cm.

Commonly accepted standard window sizes consist of a combination of cross-sectional elements and the glass itself. 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 sash must be at least 525 mm. Moreover, on each side the window trim should include 7.5 mm of glass. Based on simple calculations, we conclude that the visible width of the glass is 510 mm. Also, the standard sizes of window openings depend on the design of the walls and the size of the quarter.

Double-hung window features, advantages

A double-hung window or door has a series of about 2-7 windows that are hinged to allow them to fold down. We use double glazing technology to create more efficient window and door systems. Double glazing windows can completely change the lighting of a room. This is due to the fact that a window is a series of panes of glass. Thus, by opening the window, you can effectively illuminate the room. When these windows are opened, ventilation improves, which ensures sufficient air circulation in the building. These windows and doors create space in the room. They allow more light into the room, making it feel more spacious. Bivalve double glazing for windows and doors have greater versatility than conventional ones. They are waterproof, so they guarantee that water will not enter 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

Double glazing technology ensures that very little heat escapes from the building, which is important in the Moscow winter. The air spaces between the panes act as insulators, preventing heat loss through conduction and convection

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.

From metal-plastic there are the most fancy shapes: round and arched ones certainly won’t surprise anyone. Lancet windows are also not new, but designer designs are made to order and embody almost any client’s fantasies. But besides this, metal-plastic windows have the most important characteristics, knowledge of which will help you choose high-quality designs for your balcony.

Window Properties

High quality, good window must comply with the declared characteristics.

Namely:

• the service life of such a window is at least 20 years;
• high sound insulation properties;
• positive thermal insulation characteristics;
• ease of maintenance and operation.

Once again, we can emphasize that absolutely any metal-plastic window should be like this, and its price does not matter.

A standard window block includes two elements - window frame and doors, either opening or fixed. It is customary to distinguish casement windows separately; they are distinguished by the engagement of the sashes with each other.

Types of metal-plastic window sections

Having thought about which window will be convenient for your home, you will have to choose what type of section will be in the window.

Metal-plastic windows can have the following sections:

• Folding section. It is possible to activate the “ventilation” or micro-ventilation mode. This type is suitable for observation windows located at a significant height, as well as attic areas.
• Rotating section. The flap in it can open inward, which entails a large flow of air. The sash opens outwards in rare cases.

• Swivel section. Combines both functions, which makes this type sections are very popular.
• Blind section. The section cannot be opened, as it is completely adjacent to the frame, but, nevertheless, can be dismantled.

IN different rooms and rooms different windows are needed, so it cannot be said that there is any universal type sections.

How to choose metal-plastic windows (video)

Features of choosing metal-plastic windows

The most important thing in choosing is to take into account the characteristics of the room where the window will be located.

• Apartments, houses, offices require windows with two-chamber and three-chamber double-glazed windows - they are warmer, more comfortable, and generally more advanced. Single-chamber windows are used for warehouses and various purposes of non-residential premises.
• Reliable thermal insulation is the most important criterion for choosing a metal-plastic window if the building is located on the windy side.
• Tinted metal-plastic windows are needed if the room is located in sunny side buildings and other structures do not block the house. Windows can be with a special film that has reflective pollination, or with a silver-based coating.
• If the building is located in the city center, or in an industrial area, they are not protected from dust. Therefore the window with mosquito net in this case it is mandatory.

• With absence natural ventilation, you need to select a special profile. It is constructed in such a way that even with the doors closed, a slight air circulation is maintained. Otherwise, you will have to keep the ventilation mode all the time.
• If the apartment is on the lower floors, the owners are not insured against attacks by window burglars. To prevent them from causing harm, you need to equip yourself with additional locking fittings; they are usually installed on the handles. A bead is also used to close the gap between the impost and the sash.
• If the double-glazed window is intended for shops or office buildings, then the windows with outside can be covered with a special impact-resistant film. In some cases, armored glass is ordered.

These are just the basic selection criteria, which, in principle, are enough to ensure you don’t make a mistake with your purchase.

The quality of metal-plastic windows - what to pay attention to

The seller may claim that the window is durable and warm, but you can verify this by looking at the structure yourself. Thermal insulation and strength depend directly on the thickness of the walls, as well as the width of the cross-section of the profile. Usually, as mentioned above, the average statistical conditions in our country suggest the choice of a three-chamber or two-chamber profile.

Narrow frames are also popular, but they only make sense to be installed in those houses where there is external insulation. And, for example, in a panel house this window will not protect against the cold.

As for color, the most popular is, of course, white. But even if the seller cannot offer a profile of your preferred color, today many people cover it with a special film or acrylic varnish. But the window will definitely look better if a coloring pigment was added to the polyvinyl chloride during the manufacturing process of the profile.

How to choose a good seller

There are many companies offering window installation. And the flyers look promising.

In order not to make a mistake, it is advisable to pay attention to the following points:

• Require certificates for components and finished windows.
• Check what the seller includes in the total cost of metal-plastic windows, whether window dismantling is included in this list. This is especially important when it comes to installing balcony windows.
• The warranty period should be high enough.
• Take the time to look at the showroom of the company that produces windows.

No one has canceled word of mouth, so it’s never superfluous to listen to reviews.

Today, metal-plastic double-glazed windows open up more and more possibilities - for example, thanks to them, a balcony can be turned into a separate room. Be it a place with a sleeping place and a lamp where you can read and just relax. Or a minibar with a table for two and a beautiful view of the city. Or maybe the balcony will turn into the housewife’s workshop, where she will store everything that helps make the house cozy. The main thing is that it is double-glazed windows that make it possible to realize such attractive prospects.

Good choice!

Rules for choosing PVC windows (video)

Attention, TODAY only!

A metal-plastic window is a window made from PVC plastic with a metal profile in the middle to enhance the rigidity of the structure.

Metal-plastic window design

A metal-plastic window consists of a frame, sashes, fittings, double-glazed windows and a rubber seal.

The basis of a metal-plastic window is a PVC profile, in the middle of which a reinforcing metal frame is installed, which imparts rigidity to the system. The PVC profile contains jumpers that create air compartments, the so-called chambers. The more cameras, the warmer the profile. Typically a profile has 3,4,5 or 7 cameras.

The reinforcing profile can be U-shaped, L-shaped or closed. In a conventional section, the reinforcing profile is a rectangle. Located metallic profile in the central, largest chamber.

IN installation of a metal-plastic window glass unit included. A double-glazed window is a window element consisting of two or three glasses separated by air or gas space. Two glasses with a layer of air or gas (argon) are called a chamber. The glass unit chambers are sealed.
