They come in both rectangular and other shapes. geometric shapes. To calculate the size of a plastic window, take data on the size of the light-aeration opening. In construction, it has long been known that for optimal illumination, the window area should occupy 10-15% of the total area of the walls of the room.
For any person using a plastic window, it is important exactly how the sashes are opened.
Plastic windows traditional design. In such windows, the sashes open into the room, which makes it easy to wash their outer part. This type of window has one serious drawback: in order to open it, you need to clear the window sill of everything unnecessary. There is an improved version of this type of window, in which the sashes can be opened both outward and inward.
The opening of folding plastic windows occurs in the vertical dimension. Opening is from top to bottom at a slight angle. With this type of window opening, there is an excellent opportunity to ventilate the room. The main disadvantage of tilt windows is that it is very difficult to clean the outside.
There are forms of windows that do not open at all - these are the so-called fixed windows. This window design is the cheapest to manufacture. The scope of application of fixed windows is quite limited. They are very advantageous to use in buildings where an optimal climate air balance is constantly maintained using an air conditioning system. These plastic windows are difficult to clean from the outside. multi-storey buildings and for this purpose it is necessary to attract industrial climbers. Fixed windows are produced en masse for glazing skyscrapers, since at great heights it is advisable not to open windows. Due to their scope of application, they are equipped with high-strength glass. This type of window is also often used in industrial buildings, shopping and entertainment centers that contain climate control systems. Fixed windows can also be used in residential buildings, installing them in technical rooms and on staircase landings.
Various PVC window shapes, in which the doors open in a tilt-and-turn manner are the most popular. This window option combines the advantages of two types of opening, which allows, if necessary, to easily wash the plastic window from all sides, to ventilate the room perfectly, etc.
Shtulpovy opening is a specific method that is used in double-leaf plastic windows. It functions on the basis of the relationship of the valves with each other. The hinged opening form is most often used in conjunction with a non-standard form of window construction: semicircular, trapezoidal, round, oval, triangular, etc. The window handle first allows a person to open the main sash, and then the additional window sash. As a result, the opening of the sashes at the same moment forms a single opening without a vertical partition.
There is another interesting type of opening plastic windows - sliding. When opening such windows, the sashes diverge to the sides thanks to special fittings.
The client can order any window shapes, just pay careful attention to the dimensions of the room where the window will be inserted, as well as how it will harmonize with the facade of the building and interior design. Take note of which method of opening the sashes will be used in the window; this will determine how convenient it will be for you to use it every day.
Construction of plastic windows.
Let's consider standard plastic window design. Its structure includes: frame, impost, sashes, glazing beads. The frame of a plastic window is a fixed part of the structure installed in the window opening. The sash is the part of the plastic window that opens and closes; it is attached to the frame. When you see that a plastic window is divided into parts by a horizontal or vertical strip, it means it has an impost. Glazing beads are strips that hold the glass unit in place.
According to the method of opening, the doors are divided into the following types:
1. Tilt and turn - the window sash rotates around the vertical and horizontal lower axis.
2. Rotary - the plastic window sash rotates around a vertical axis.
3. Transom - the window sash rotates around the lower horizontal axis.
Double-glazed windows are a structure consisting of hermetically sealed glass. Most often in the manufacture of plastic windows, glass with a thickness of 4 mm is used, but there is also glass of greater thickness. Triplex double-glazed windows are a special category; they have very high strength. Triplex in its design consists of two sheets of glass bonded together with a transparent film.
Double-glazed windows, depending on the number of chambers, are divided into 2 types:
1. Single-chamber - the length of the chamber between two glasses is 24 mm.
2. Two-chamber - two 34 mm cameras and three glasses.
In the internal space of the PVC profile, the role of stiffeners is performed by transverse jumpers. They create inside the profile a large number of compartments that are filled with air. It is these compartments that give the profile insulating properties. How warm the profile will be depends on the number of these compartments; the more, the better.
Plastic windows of any shape Another good thing is that they are safe for health, since the material from which they are made is chemically neutral, and therefore does not react with moisture and air.
IN last years More and more plastic windows with three chambers are being produced, as their performance characteristics are higher. When choosing a profile, you need to focus on the size, location of cameras and their number. The profile configuration is designed so that each camera performs its own function. One serves to drain water, the second increases the rigidity of the profile, and the third secures the fittings.
Importance window opening for any building or structure cannot be overestimated. Thanks to them, premises owners have the opportunity to save on electricity and create a favorable microclimate in living rooms. But for this you need to select quality window PVC that meets all needs and requirements.
From simple to complex
Research shows that only high-quality plastic windows meet all standards and requirements, as well as price preferences. It is not surprising that these products are very popular among consumers, which is based on the following parameters:
- availability;
- various types;
- reliability and quality.
Availability is expressed in the cost of plastic windows, which is still the lowest of all categories of goods for this purpose. Moreover, photo and video installation materials allow you to perform the installation yourself. At the same time, plastic requires virtually no maintenance, which is also appreciated by buyers. Reliable locking mechanisms allow you not only to open the doors, but also to use them for various modes of air supply to the room.
But most importantly, these are a variety of types and shapes of window structures, which allows you to make glazing not only functional, but also visually attractive. There are all the prerequisites for this. The user can choose from the following product forms:
- rectangular;
- square;
- trapezoidal;
- arched;
- round.
Based on these types, a lot of more complex products are produced, the sizes of which are limited only physical characteristics PVC profile. Simple designs do not contain at all or in small quantities additional details dividing the window space into individual fragments that can be opened. And more complex options are able to surprise with their design and functionality, which is what attracts modern builders and designers.
For non-residential premises and production
The shape of the window frame is not the same for rooms of different purposes. For non-residential or industrial buildings, certain types of structures are used that have a simpler manufacturing option. As a rule, these are blind frames with no sash that can be opened. They are intended only to illuminate the interior space, and therefore do not require additional mechanisms.
In some cases, simple window designs that can be opened are used. Most of these products only use the tilt function, where the top of the sash swings halfway down, stopping at a 45-degree angle. This is quite enough to obtain the fresh air needed for comfortable work of people. Photos of such products can often be found on enterprise websites.
There are also combined forms, when blind structures are diluted with a transom located in the upper part. This type has a large size to receive quality lighting space inside a workshop or warehouse. It is worth noting that the cost of such PVC windows is quite low, which attracts many managers.
Variety of types for residential premises
If production areas require simple structures, then for residential buildings products of more complex configurations are used. This is due to the desire of the owners to obtain beautiful and multifunctional window systems that provide comfortable living. Therefore, in manufacturers’ offices, buyers carefully study every photo of the product offered.
Most often, for apartments, a design with two doors is chosen, one of which can be opened in several planes (turn and tilt).
Triple-leaf plastic windows are also used for spacious rooms. In this case, one part always remains blank, since it does not play a key role either in ventilating the room or in caring for the structure. There are also types in which a blind transom is located at the top. She is responsible only for the light space.
For the construction of buildings according to individual projects exclusive plastic windows are required. This involves manufacturing not according to accepted standards, taking into account the design of the facade, which looks harmonious when viewed from the street. Such designs look impressive not only in photos, but also in a real project. Arched profile bends are almost always present in such structures. But there may not be so many opening sashes, since the main function of these plastic windows is aesthetics and beauty. But the structures will be reliably protected from external precipitation, as well as wind and other troubles.
When choosing the required window system You should pay attention not only to aesthetic forms, but also to the quality of the profile itself. The service life of the product depends on it. In addition, the locking system should also be inspected, since if it fails, the entire structure will no longer be able to open. Therefore, the choice should not be based only on photo materials.
Heating and cooling glass
What else is the difference between plastic windows and all others? The presence of a double-glazed window, which makes these designs unique. There are two types, differing in the number of spaces. Double-glazed windows with one chamber are cheaper, but also less temperature-resistant. For severe frosts and high heat, double-glazed windows should be used. Only with the help of such PVC windows will the interior be cool in summer and warm in winter.
The strength of the profile when using a double-glazed window with two chambers should be maximum. Otherwise, if you open such a sash, it may not hold up and become deformed, rendering the structure unworkable. But for elite products this is unacceptable. Therefore, all types of window structures are made from reinforced profiles.
When choosing a double-glazed window, you should pay attention to the size of the chambers themselves. Now you can purchase systems with different widths between the glasses. It is assumed that the space can be filled with a special gas. Only it guarantees the absence of dew point on inside PVC windows, but its validity has its own period.
The main advantage of wooden windows is strength, reliability, high sound and heat insulation. Wooden windows differ in the way the sashes are opened and in their design.
Wooden window design
Window with a separate wooden part (Russian windows)
Such a window has one frame and two sashes that open sequentially, both with glass. The wooden part consists of solid pine, and not of laminated veneer lumber. Doors with a thickness of no more than 40 mm. The main disadvantage of such a wooden window is that due to high humidity and temperature changes, warping and deformation occur.
The narrow profile does not allow for multi-profile milling, which in turn excludes the possibility of installing several sealing contours. Therefore, the sashes in such a window do not have a tight connection to the window frame.
The absence of an aluminum profile on the frame, which covers the door of the frame and the doors, allows water to flow from the outside onto the window sill. These wooden windows are equipped with conventional non-adjustable hinges and handles. Such fittings make it impossible to adjust the doors and tilt them for ventilation.
Windows with double glazed windows - wooden euro windows (German windows)
The name Eurowindows comes from the fact that they are installed. It is installed around the entire perimeter of the wooden window sash, there is the possibility of adjustment and tilt-and-turn opening, and there are many locking mechanisms.
The design of a wooden euro-window consists of a window frame and a sash. The sash has a double-glazed window, usually two-chamber, most suitable for the Russian climate. The window opens with one movement. Therefore, when washing windows, we only have two sides, outside the window and on the side of the room.
Video: Types and range of glass for windows
Manufacturers of wooden windows mainly use timber with a thickness of 68 - 78 - 88 mm. The thickness of the timber allows for a multi-circuit seal, as well as grooves for fittings and a 44 mm wide double-glazed window. The design of a wooden euro-window has many advantages: warm, reliable, comfortable, durable.
Service life - more than 70 years. Long term service is due to laminated veneer lumber, which is glued together from 3 lamellas. The slats are glued in such a way that the wood fibers are located in different directions. This glued construction does not allow it to dry out, warp or lose its geometric shape.
Wood window - aluminum
Let's take what was described above and line it on the outside with aluminum, and as a result we will get the so-called. That is, in essence it is a wooden euro-window, only of better quality. The advantage of this window is that it practically does not require restoration of the external paintwork.
Aluminum - wooden window
The name is similar to the previous window, but in design they are completely different. In this window, the load-bearing part of the window is completely made of aluminum. In principle, this completely covers it from the inside of the room.
The wooden panel makes the window warmer and more beautiful. While inside the room you will see wooden window, made from such valuable wood species as oak, beech, ash. The design combines the lightness and durability of aluminum with the warmth and beauty of natural wood.
On Russian market aluminum-wood windows are rare due to their high cost aluminum profile, which is purchased in European countries.
Finnish window
The wooden window has a wide frame up to 180 mm and two sashes that open sequentially. The outer sash is equipped plain glass, and is inserted into the inner one. The outer sash can be wooden or aluminum.
They are connected to each other by a joint opening mechanism, which will allow them to be opened simultaneously or separately by opening the mechanism. The frame and sashes of a Finnish window are made of solid wood, and not of laminated veneer lumber.
Unlike Euro-windows, the cross-section of a Finnish window is only 40 x 40 mm, so although it looks more attractive and elegant, it does not have the advantages of laminated veneer lumber. The sashes in the Finnish window do not have a tight clamp around the perimeter due to their fittings, so they cannot be tilted and turned.
All this design differences wooden windows, but they may also differ in the way the sashes are opened.
Solid wooden windows
The window has no moving parts and cannot be opened. The cost of such windows is cheaper due to the fact that they do not use fittings. A fixed window can have several double-glazed windows between which there is an impost. Before you decide to install a fixed window, you need to think about how you will wash it and ventilate the room.
Single-leaf swing and tilt-and-turn wooden windows
For a single-hung pivot window, the sash opens only in one direction—horizontally. Mostly they open indoors, there are also options with external opening. The hinged flap opens both horizontally and vertically - ventilation mode.
Double-leaf, fixed - tilt-and-turn window
They are made from laminated veneer lumber and have two doors. One is blind and one is a tilt-and-turn one, which opens and folds down on the lower suspension into ventilation mode. Such double-leaf wooden windows are very popular.
Double-hung, pivot and tilt-and-turn window with mullion
An impost is a wooden profile that connects several sashes into a single structure. used for the narthex of sashes and their hanging. A wooden window with an impost is the most convenient, reliable and durable option. Due to the window being equipped with tilt-and-turn fittings and an additional profile, the price of this window is higher than that of a fixed window.
Double-leaf swing and tilt-and-turn wooden windows
Such windows open according to the same principle as those described above. The window sashes are dependent and connected by a hinge. The first sash is equipped with tilt-and-turn fittings with a handle, the second without a handle.
The second leaf opens only if the first one is open. When the sash is open, the window opening will be completely free, since there is no impost, and the frame is attached directly to the sash and is not visible.
Now that you know at least a little about the types of wooden windows and their design differences, you can choose the right wooden window for your home or apartment.

Today, windows are made from a variety of materials and can have very different shapes. Based on this, you can ask the question: what types of windows are there? The correct answer to the question is the classification of products.
For example, they can be divided into types according to the material used to make them:
- PVC structures;
- wooden;
- aluminum;
- combined view windows.
In addition to the material, frames can be divided into groups according to design:
- paired;
- separate;
- single.
Today, products can be with single glazing or double glazing.
Classification of windows by material
Today, systems are manufactured using very complex technologies, which achieves excellent results in heat and sound insulation. Products made from PVC are very popular today. But for those who prefer the classic version, wooden frames are also manufactured using new technologies. As a result ready product radically different from old wooden ones.
Metal-plastic.
Metal-plastic structures have been known to the world for more than 50 years. They appeared on the territory of our country much later. All products were imported from other countries, since domestic production was not established. Today, using technology from leading brands, products are manufactured in the country. The metal-plastic device consists of:
- polyvinyl chloride profile;
- reinforcement made of galvanized steel, which is located inside the profile chambers;
- high-quality fittings;
- glass unit.
By using PVC profile in production conditions, you can create a window of completely different configurations.
Aluminum windows.
Many people associate aluminum with industrial buildings, offices, shops. It is in such establishments that aluminum aluminum frames are most often used. window frames. Due to their strength, such frames are installed in houses where they will be subject to intense loads. Also, very often such metal frames are used for the construction winter gardens, glazing of balconies. This is the frame that will allow you to create a window large sizes.
Wooden windows.
Previously, only wooden windows were installed in houses, which over time became deformed, cracks formed, through which heat was lost and cold entered. Today, in order to create a wooden window, new technologies are used. For the manufacture of such windows it is used hard rock wood or three-layer timber. It is the use of laminated veneer lumber that completely eliminates the possibility of any deformation. The glazing is modern single- or double-chamber double-glazed windows.

Combined type of windows
According to experts, such windows will soon occupy a leading position in the field of glazing. This is due to the fact that such windows use several materials, for example, wood and aluminum, wood and plastic, etc. Having absorbed the most best qualities materials used, such windows will last very long long time without causing unnecessary hassle in your service.
The most striking option for a combined window is a structure made of a three-layer profile. The first layer is decorative, made of wood. The second layer is made of metal, it protects the structure from impact environment, and also gives the frame rigidity and stability. The third layer is made of polyvinyl chloride; the main purpose of using this material is to significantly increase the thermal insulation qualities.

Key Features
Windows are a source of natural light in the apartment and access to fresh air. This is especially important in apartments where ventilation systems do not work so well.
But at the same time, they create significantly greater heat loss during the cold season. It is through glazing that the largest amount of heat is lost. In order to significantly reduce such losses, it is necessary to select the correct profile, clarify the design of the glass unit, and check all joints. Additional measures Blinds and curtains can be used to retain heat.
Double-glazed windows.
The number of glasses in a double-glazed window plays a very important role in heat retention. There are options for windows with one glass, but heat loss in this case will be maximum.
A double-glazed window, in which two glasses are installed, forms a kind of air gap that will reduce heat loss. Modern double-glazed windows can have two or three sheets of glass. Additionally, the space between them is filled with dry air or gas.
All joints are closed with sealing profiles.
In addition to light, extraneous sounds and noise enter the room through the windows. Sound insulation will depend on the number and thickness of glass. To minimize the passage of extraneous sounds, it is worth taking care to seal all joints, not only the window structure, but also the junction of the window and the opening.
When choosing a system, it is worth Special attention pay attention to the type of opening. Today, thanks to accessories, products can be:
- folding;
- rotary;
- tilt and turn;
- deaf;
- sliding.
Blind design.
This design does not involve opening the doors. The product costs much less than other options and is as reliable as possible. It is used in houses quite rarely, since it is almost impossible to wash it from the street if it is not located on the ground floor. The only option may be to completely remove the glass unit and then install it in place. Fixed windows can be installed on the side walls of the balcony or in the entrances. They can also be installed in private homes as a source of natural light in the hallway or terrace.
Folding design.
If the window is equipped with tilting fittings, it can be opened to the ventilation position (vertical opening). In this case, normal opening is not available. Like a fixed window, this design does not have access to the outside, which prevents the window from being cleaned. Such a window can be installed in a place where full opening cannot be achieved. This is possible if the layout of the house does not have enough space to allow the sash to open completely. But, unlike a blind window, such a window allows you to gain access to fresh air.
Rotating window design.
The rotating design opens in the traditional way. This method allows you to gain access to the outside and adjacent doors. This design is very easy and convenient to care for. The disadvantages include the need for free space, which will allow the doors to open freely. Similar elements are installed in almost any room.
Swivel and tilt design.
The most popular and common type of opening. Those. allows you to open as classic version, and leave the element in the ventilation position. They are also installed almost everywhere.
Sliding system.
This opening system metal-plastic windows appeared relatively recently. This opening method allows you to open all windows completely, even in the narrowest room. This system is most often used on loggias and balconies. The quality of windows with such an opening system is no different from the usual opening system. All joints are completely sealed and do not leak cold air inside.

1. Window shape
Windows to some extent determine appearance buildings. Windows of non-standard shapes decorate the facade of the house and can even give it some originality. The small single-pane windows on the façade are depressing, giving the building the appearance of a prison.
Modern technologies make it possible to create windows of various shapes. It is possible to recreate windows of any historical style, preserving the facades of buildings of historical value. Windows can be either simple rectangular in shape or complex arched or pointed structures. On the gables of buildings you can often see round, square or triangular windows. The impression of a window is created by its single or multi-leaf design. Modern windows are decorated with trims or decorative ornamental profiles made in various combinations of color and decor. Transoms are used in window designs. A rectangular window may have bevels.
Windows are a necessary part of the interior to create comfort in the home, as well as to save money on heating interior spaces. It follows that the shape of the window is related to the functional use of the room, as well as to the opening capabilities required of the window.
Any modern materials: wood, plastic, aluminum, fiberglass - allow you to create any shape of windows. But the more complex the shape of a window, the more expensive its production is, which is associated with the complication of technological processes.
Also, when choosing the shape and, especially, the size of the window, you should remember that open window sashes that are too large will place an excessive load on the fittings and frame structure due to the large weight of the sashes or double-glazed windows themselves. In addition, open doors will take up interior space when opened into the room. Large window sashes are quite difficult to clean. The recommended dimensions of the sash are a rectangle 80 cm wide and 130 cm high.
2. Window classification
Windows are classified according to the following criteria:
materials of frame elements;
· options for filling the translucent part;
· purpose;
· design options;
· architectural drawing;

· with decorative bindings;
· with a complex pattern (for example, arched with slab binding).
Products are classified according to their main performance characteristics:
· reduced resistance to heat transfer, air and water permeability,
Sound insulation, overall light transmittance, resistance
· wind load, resistance to climatic influences.
3. Window opening options
Fixed (non-openable) or blind windows.
They are used when there is an initial need to have a fixed window sash. In such windows, the frame itself can hold the glass. Blind sashes are mounted as an isolated element. In order to lighten the load on the window structure, a lintel is built above the window at a certain width. When a roller shutter box is installed, it takes on the vertical load.
Fixed or fixed windows are often round or triangular windows on the gable of a building.
A fixed or fixed window can only be washed from outside.
Attention! When installing such windows, if they are the only opening options in the room, it is necessary to think in advance about the method of ventilating the room. IN modern windows Ventilation valves are built in from PVC.
Exposed windows.
Exposed windows are essentially fixed windows, the frame of which can be removed for, for example, cleaning and cleaning.
Pivot or casement windows.
Pivot or hinged windows can open both inside and outside the room; they can be either with an impost or hinged.
Pivot or casement windows are easy to clean. With the help of such windows you can perfectly ventilate the room.
Hinged windows (with bottom hinge).
Hinged windows open from the top. Such windows are called transoms. They are used on stairwells as they are the least safe, since casement windows can be a source of danger for children without adult supervision. Hinged windows are installed in basements, industrial and other rooms where open sashes may be in the way. When installing this type of window, remember that they must be accessible for maintenance and cleaning.
For transoms, only the folding type of opening is suitable, and there are various options transom fittings that allow you to control the opening depending on the size and design features window.
Tilt and turn windows.
A tilt-and-turn window is a window, the same sash of which, at a certain position of the same handle, can be opened either by rotating around a vertical axis at an angle of up to 160°, or tilted on the lower hanger, resulting in a gap for ventilation. There are special fittings that allow you to fix the opening angle, protect the doors from spontaneous slamming, etc.
Tilt-and-turn windows provide full ventilation of the room instead of traditional vents. At the same time, installing a window with a window makes the tilting opening option pointless, which only leads to an additional increase in cost compared to the usual rotary opening option.
Hanging windows.
Hanging windows can be classified as tilting windows. Their peculiarity is that the window opens by turning around the upper extreme axis or from the upper suspension.
Mid-hung windows.
Mid-hung windows are windows rotating around a vertical or horizontal axis located in the middle of the window vertically or horizontally, respectively.
Mid-hung windows are very easy to clean. They ventilate the room perfectly.
Sliding windows.
Sliding windows are windows whose sashes move parallel to the window installation plane, moving relative to each other or retracting into the walls.
Sliding windows save space. They are built into any design and even decorate it, but are more expensive than other windows due to the complexity of the design and the presence of additional fittings and mechanisms. Especially often sliding windows used for balconies and loggias.
