GOST PVC windows (plastic windows), aluminum, wooden window blocks, double-glazed windows

This section presents only current GOSTs for windows and double-glazed windows. Previously, other standards were in force, which were replaced by the standards listed below. You can download these documents for free.

Under each GOST for window units there is information about the date of introduction. The previous numbers of standards for windows that were in force before the entry into force of the updated standards are also indicated.

Regulatory framework plastic windows in our country has been formed by almost two dozen GOSTs, most of which are the reception of German and/or European standards, SNiPs and industry specifications, although it should be recognized that the package regulatory documents has not yet become sufficient, but only conditionally necessary to regulate all issues arising during the development, assembly, installation and operation of translucent structures based on PVC profile systems. The fundamental documents for the development of glazing structures for apartments, private houses, buildings, including premises specific for their purpose (attics, balconies, loggias, bay windows, verandas) are SNiP 02/23/2003 Thermal protection of buildings, MGSN 2.04-97 Acceptable levels noise, vibration and sound insulation requirements in residential and public buildings, GOST 30674-99 Window blocks made of polyvinyl chloride profiles and general GOST 23166-99 Window blocks. General technical conditions.

Here you need to understand that GOST 23166-99, which regulates the general provisions for windows made of wood, PVC, steel, aluminum, and the profile GOST 30674-99, in the development of which KVE specialists from the Profine GmbH production group were involved, despite being put into effect in one year have differences, although not contradictions, and therefore the basic document for plastic windows today is GOST 30674-99 Window blocks made of polyvinyl chloride profiles, as well as the accompanying GOST 30673-99 PVC profiles for window and door blocks. At the same time, GOST 30673-99, as well as SNiP 23-02-2003 in force today, are already morally outdated and many manufacturers of profile systems for the status of branded products have long gone beyond the norms of domestic acts, of course, in the direction of improving the mechanical and thermophysical characteristics of the profiles they produce . Some companies and production groups work according to their own standards and/or specifications, the stringency of the requirements for the quality characteristics of profile systems significantly exceeds the standards established in GOST 30673-99, which in general, when using appropriate double-glazed windows, makes it possible to reach the European level of thermal protection standards for translucent glass structures made of rigid PVC.

Similarly obsolete today are GOST 30778-2001 Sealing gaskets made of elastomeric materials for window and door units, GOST 10174-90 Sealing polyurethane foam gaskets for windows and doors and, even more so, GOST 19177-81 Rubber porous sealing gaskets, which do not cover the full range of modern seals for the contours of the ledges of plastic windows, as well as seals of sliding systems, which are mostly patented by manufacturers in last years and are effectively used by assembly companies or welded onto the profile during its manufacturing process.

GOST 30777-2001 Rotary, tilting and tilt-and-turn devices for window and balcony door units and GOST 5087-80 Handles for windows and doors became no less problematic in terms of information content and standardization, since well-known hardware manufacturers literally every year offer innovative design solutions for hardware fitting systems , integrating modern electronic control systems into them, adapted to new security systems for homes and buildings. Moreover, even mechanical sliding fittings for plastic structures for balconies, loggias, as well as parallel-exposed fitting complexes for plastic windows are not regulated at all by domestic GOSTs and so far the State Construction Committee is not carrying out work in this direction.

The regulatory framework for glass and double-glazed windows is in a slightly better position, the basis of which is GOST 111-2001 Flat glass, GOST 30698-2000 Tempered building glass, GOST 2486689 Glued double-glazed windows, as well as GOST 30733-2000 Glass with low-emission hard coating and GOST R 51136-98 Multilayer protective glass, although there are still no domestic regulations regulating selective glass, self-cleaning glass, curved glass, etc. as well as double-glazed windows with inert gas and vacuum, which are already sold in the USA and Japan, although in limited sizes. A GOST 30779-2001 Double-glazed windows for construction purposes. The method for determining weather resistance and assessing durability does not at all form an integrated approach to testing modern double-glazed windows in all their diversity and differences in thermophysical and mechanical characteristics.

Methods for assessing the performance characteristics of window structures, including those made from PVC profile systems, are set out quite fully and almost in accordance with European standards in GOST 26602.5-2001 Window and door units. Methods for determining resistance to wind loads, GOST 26602.4-99 Window and door blocks. Method for determining the total light transmittance, GOST 26602.3-99 Window and door blocks. Method for determining sound insulation, GOST 26602.2-99 Window and door blocks. Methods for determining air and water permeability, GOST 26602.1-99 Window and door blocks. Methods for determining heat transfer resistance. Many of these standards are copied from German DIN and this makes them conditionally relevant, although probably not for long.

The most recent standard of Gostroy today is GOST R 52749-2007 Window installation seams with vapor-permeable self-expanding tapes, in fact, duplicating GOST 30971-2002 Assembly seams of junctions of window blocks to wall openings, which was never implemented at the time due to recommendations, and not the binding nature of the normative provisions set out in it. At the same time, the vast majority of domestic companies, freelance installers and teams of shabashniks install plastic windows the old fashioned way with training to blow out the installation gaps construction foam, and control over the implementation of the current GOST R 52749-2007 is traditionally declarative for our country, but not real.

Characteristics

GOST for plastic windows. Basic guidelines for installing plastic windows.

Plastic windows are installed, most often, without prior consultation with the customer, because the cost of the window is reduced if a simple, cheap format is used. However, good quality windows must always be installed strictly in compliance with the standards of GOST 30971-2002, as well as GOST 23166-99, GOST 30674-99, GOST 24866-99 and GOST 30971-02.

GOST 23166-99 General windows

This standard defines the scope of application, general information about window blocks, basic terms and their classification. It is used when installing wooden, plastic and metal window and balcony blocks.

The standard is fundamental for a set of standards standards designed for certain types designs of window blocks and details of their configuration. When installing plastic windows, compliance with the rules of this standard is mandatory. In addition, this GOST is used for product certification. All window units must comply with the norms and requirements of this standard; their production must take into account the design and technological documentation approved in the prescribed manner.

Plastic window products manufactured in accordance with GOST 23166-99 must consist of certain frame elements, such as frames, sashes, leaves, vents, transoms. The corner joints of these elements of window frames are connected using glue and tenons, mechanical connections, welding or other methods. The standards provide design solutions that are mandatory for use in production corner connections for certain types of window products.

Constructive solutions for window units in mandatory must provide for ventilation of the premises using sashes, vents, transoms or ventilation valves. Experts recommend using devices in product designs to regulate humidity and temperature conditions: self-ventilation systems and climate valves.

The design of the product must provide for the possibility of installing and using several circuits of sealing gaskets located in the recesses for window units intended for use in poorly heated rooms. The designs of window products must take into account the possibility of replacing glass, sealing gaskets, various window devices and double-glazed windows without compromising the integrity of the product.

GOST 30674-99 PVC windows

This GOST defines the areas of application, classification of windows and their functions. This standard also defines the technical requirements for plastic windows. This standard is intended for control during the manufacture and installation of window and balcony door units made of polyvinyl chloride profiles in accordance with GOST 30673, their design is single, they are used in buildings and structures of various types.

In addition, the requirements of the standards apply to products that are glazed with sheet glass and are intended for use in unheated buildings. Specific product brands can be used depending on the existing operating conditions, taking into account SNiP and regulatory requirements GOST 23166.

Compliance with the requirements of this standard is mandatory.

Products are classified according to GOST 23166; their design options and type of surface finishing may vary for PVC profiles.

As you know, window blocks are divided into 1-4-chamber ones depending on the design of the PVC profile. Products are also divided depending on the type of finish; they are white, body-dyed, laminated and have a co-extruded front covering.

When placing an order for the supply or production of individual window products, you should indicate options for a design solution in accordance with GOST, include a description of profile structures and double-glazed windows, drawings indicating opening patterns, describe the types of window devices, and determine the requirements for appearance windows and other requirements. The installation of plastic windows must be carried out taking into account the requirements of GOST. in agreement with the manufacturer.

Technical requirements

Window profiles must comply with all the norms and requirements of these standards, GOST 23166, and be produced taking into account the design documentation, which is valid and approved in the prescribed manner. It is necessary to take into account the design of products consisting of frame elements that are welded from PVC profiles and reinforced with steel liners. IN window profiles imposts are fixed in frame elements using welding or mechanical connections. The design of products, with the exception of unheated rooms according to GOST, includes two or more rows of sealing gaskets in the recesses.

Among the main GOST standards used when installing plastic windows are GOST 24866-99 double-glazed windows and GOST 30971-02 installation seams.

They contain information about the scope of use of double-glazed windows, their list and classification, as well as basic parameters. GOST defines technical requirements and necessary recommendations for installation and installation of windows. GOST 30971-02 is used when installing window blocks and determines the classification of designs of various installation joints, regulatory technical requirements for the materials used, dimensions and surface preparation.

Instructions

Most likely, no one will argue with the fact that if installed incorrectly, even expensive windows are unlikely to work well. For this reason, if you plan to install your new windows yourself (at the same time taking upon yourself the entire burden of responsibility for the quality of installation), then in this case it will be useful for you to pay attention to the subtleties and a number of possible difficulties, which are rarely mentioned.

So: the biggest problem is correctly determining the size of your future windows. This is quite difficult, since an old wooden window is installed in the opening, which makes it very difficult to determine all the necessary measurements. It is for this reason that already at this stage a time bomb can be laid, which can turn any editing into a search for a feverish solution to the problem of breaking out of their deadlock. Therefore:

1. Rule No. 1:

The worker who takes measurements must have excellent spatial imagination and an analytical mind; he must be well acquainted with the design of future windows, and also possess personal experience installation Believe me, the combination of all these qualities may not occur very often. They are also not so easy to raise, so most often you have to make do with fewer requirements, hoping for chance, and problems that often arise have to be solved on the fly (over several years). What does a surveyor need to take into account so that the entire enterprise does not simply go down the drain, and installers do not spend the night on site?

2. Rule No. 2:

Measurements of your future window must be taken from both sides of the opening: inside (from the room), and also outside. Both of these parameters are needed in order to more accurately determine the depth of the window opening. Obviously, the window must be no smaller in size than the outer dimensions of the opening so that it does not fall out. But how much more this depends on a large number of difficult to predict factors, which we will discuss below.

3. Rule No. 3:

You should never forget to check whether the outline of the existing opening will be preserved on the outside for your next visit. After all, they can remove it from it old plaster, sew clapboard, lay an additional row of bricks, or a team of builders will generally expand it to incredible sizes without any prior notice.

4. Rule No. 4:

It is also necessary to take into account the fact that the window opening may be very skewed (this is especially true for panel houses). All this can lead to an increase in window sizes just by the amount of skew. That is, in order to prevent the formation of through gaps between the edge of the window opening and the window frame, the size of your window must be larger than outer size the window opening is approximately 35-40 mm in width and 12-18 mm in height. There are several ways to do this: you can increase overall dimensions window boxes or you can expand your window using additional profiles that snap onto the box.

5. Rule No. 5:

You need to make sure that your tastes and the taste of the customer completely coincide regarding the appearance of the windows from the street side. After all, some people like almost the entire window frame to be embedded in the wall and not be visible from the outside at all. Others prefer to show the window in all its glory. It's difficult to determine who is right here. If the first option is more preferable, then you should not forget about all sorts of distortions in the window opening, so as not to overdo it at all, when not only the window frame, but even part of the double-glazed window will be hidden inside the wall. The second option is more preferable, since there are fewer opportunities to make mistakes, as well as fewer consequences.

*Notes* 1 The reduced heat transfer resistance of the opaque part of the filling of balcony door blocks must be no less than 1.3 times higher than the heat transfer resistance of the transparent part of the products, but not lower than 0.8 m 2 °C/W. The values of the reduced heat transfer resistance of a combination of product profiles should not be lower than this indicator for double-glazed windows by more than 15%. 2 The values of the reduced heat transfer resistance are established for products with a ratio of glazing area to product area equal to 0.7, and an average thickness of the profile combination of 58 - 62 mm. 3 The deadline for entering the durability indicators indicated in brackets is 07/01/2002.

Indicators of reduced heat transfer resistance for products made from profiles with a different number of chambers and a different glass unit design are taken based on the results of laboratory tests.

5.3.2 Resistance to static loads and forces applied to the doors to open and close them - according to GOST 23166.

5.3.3 Welded corner connections with machined weld seams of sashes up to 1000 mm wide must withstand the test load applied according to diagram A of Figure 9, not less than:

750 N - with sash height up to 1300 mm;

800 N - for sash heights over 1300 to 1500 mm;

900 N - for sash heights over 1500 to 1800 mm;

1000 N - with a glazing area of 2.1 - 2.3 m2 and for door frames.

The value of loads when testing the strength of corner joints of sashes with a width of over 1000 to 1200 mm is increased by 10%.

The value of loads when testing the strength of corner connections of boxes according to scheme A in Figure 9 is not less than 800 N, according to scheme B - 1600 N.

When tested according to scheme B of Figure 9, corner joints must withstand a load doubled.

5.3.5 Appearance of products: color, gloss, permissible defects

the surfaces of PVC profiles (risks, scratches, shrinkage cavities, etc.) must correspond to standard samples approved by the head of the product manufacturer.

Welded seams should not have burns, uncooked areas, or cracks. Changing the color of PVC profiles in places welds after their stripping is not allowed.

5.3.6 The front surfaces of profiles of doors and product boxes (except curved ones) must be protected with self-adhesive film.

5.4 Requirements for components and their installation

5.4.1 Materials and components used for the manufacture of window units must comply with the requirements of standards, technical specifications, and technical certificates approved in the prescribed manner.

5.4.2 The main components of the products: PVC profiles, double-glazed windows, sealing gaskets, window devices must be tested for durability (failure-free operation) in testing centers accredited to conduct such tests.

5.5 Requirements for PVC profiles

By agreement between the consumer and the manufacturer, it is allowed to manufacture products from PVC profiles of other colors and types of finishing of the front surfaces. The use of colored profiles painted in the mixture without a protective decorative coating on surfaces exposed to ultraviolet rays, not allowed.

5.5.3 Curved profiles should not have deviations from the shape (warping, waviness) exceeding the width and height of the profile (±1.5) mm. The recommended minimum bending radius for white PVC profiles should be taken equal to five times the profile width, for other profiles - 5.5 times the profile width.

5.6 Requirements for glazing, door panels and sealing gaskets

5.6.2 To increase architectural expressiveness, installation is allowed decorative layouts(slabs) on the outer surfaces of double-glazed windows using weather-resistant adhesives or the use of double-glazed windows with an internal frame (Figure 4).

5.6.3 Double-glazed windows (glass) are installed in the rebate of the sash or frame on pads that prevent the edges of the double-glazed window (glass) from touching the internal surfaces of the rebates of PVC profiles.

Depending on the functional purpose linings are divided into basic, supporting and spacer.

A- profiles of the internal frame of the double-glazed window; b - overhead decorative layouts; V - option for the combined use of overhead layouts and the internal frame of a double-glazed window; G - binding connections of layouts

Figure 4 - Options for installing decorative layouts

To provide optimal conditions To transfer the weight of the glass unit to the structure of the product, support pads are used, and to ensure the nominal dimensions of the gap between the edge of the glass unit and the fold of the sash, spacer pads are used.

Base pads are used to level bevels and folds and are installed under support and spacer pads. The width of the base pads must be equal to the width of the rebate, and the length must be no less than the length of the support and spacer pads.

Support and spacer pads can combine the functions of basic pads.

The length of the support and spacer pads should be from 80 to 100 mm, the width of the pads should be at least 2 mm greater than the thickness of the glass unit.

5.6.4 Linings are made of rigid weather-resistant polymer materials. The recommended hardness value of the support pads is 75 - 90 units. according to Shore A.

5.6.5 Methods of installation and (or) design of pads must exclude the possibility of their displacement during transportation and operation of the products.

5.6.6 The design of the linings should not impede air circulation over the inner surface of the glazing rebate.

5.6.7 If the installation location of the lining coincides with the head of the fastening screw, the lining must not be skewed.

5.6.9 The distance from the pads to the corners of the double-glazed windows should, as a rule, be 50 - 80 mm. If the width of the glass unit is more than 1.5 m, it is recommended to increase this distance to 150 mm.

5.6.10 The basic layout of support and spacer pads when installing double-glazed windows, depending on the type of opening of window units, is shown in Figure 5. In balcony door units and in products with reinforced locking devices, it is recommended to install additional pads in the locking areas.

Types of opening window units: A- non-opening; b - tilt and turn; V- rotary (swing); G - folding; d - hanging; e - installation of linings in figured window blocks

5.6.12 Installation of panels in door leaves is carried out in accordance with the requirements for the installation of double-glazed windows.

5.6.13 Design solutions for fastening units for double-glazed windows, as well as panels for filling the opaque part of the door leaf, must exclude the possibility of their dismantling from outside.

5.6.14 Installation of double-glazed windows (glasses), as well as sealing of the sashes, is carried out using elastic polymer sealing gaskets. It is allowed to use glazing beads with a co-extruded seal for fastening double-glazed windows from the inside.

5.6.15 Sealing gaskets must be resistant to climatic and atmospheric influences.

5.6.16 The fit of the sealing gaskets must be tight, preventing the penetration of water.

5.6.17 Sealing gaskets must be installed continuously along the entire perimeter of the sashes and double-glazed windows. When installing in a ring, the joint of the gaskets should be in the upper part of the product. When installing gaskets with joints at 45° corners, the joints of the gaskets should be welded or glued (except for gaskets installed in glazing beads). Corner bends and welded joints of sealing gaskets for double-glazed windows should not have protrusions (bulges) that cause concentrated loads on the double-glazed windows.

5.7 Requirements for reinforcement inserts

5.7.1 The main PVC profiles of the products are reinforced with steel liners with anti-corrosion coating.

5.7.2 The shape, wall thickness and moments of inertia of the reinforcing liners, as well as the maximum permissible dimensions of the valves when using specific types of liners are established in the technical documentation for the manufacture of products.

5.7.3 Reinforcing liners must fit into the internal chambers of PVC profiles tightly, by hand, without the help of special devices.

5.7.4 When using profiles white reinforcing liners may not be installed (except for imposts) in parts of products whose length is less than 700 mm.

When using colored profiles, as well as in the details of frost-resistant window blocks and in special cases when this is required according to the documentation of the manufacturers of PVC profiles, the installation of reinforcing liners is mandatory in all parts of the products.

5.7.5 The wall thickness of the reinforcing liners must be at least 1.2 mm; to strengthen colored and frost-resistant profiles, it is recommended to use reinforcement liners with a wall thickness of at least 1.5 mm.

5.7.6 The distance from the liner to the corner (end) of the reinforced part of the profiles should be within 10 - 30 mm. In the designs of products with glass units weighing more than 60 kg, as well as in reinforced products, it is recommended to use liners trimmed at an angle of 45°. Examples of installation of reinforcing inserts are shown in Figure 6.

Figure 6 - Examples of installation of reinforcement inserts

The length of the reinforcing mullion liners when they are mechanically attached to the box liners is determined by the design of the connection.

5.7.7 Joining or breaking of reinforcing liners along the length within the same PVC profile is not allowed.

5.7.8 Each reinforcing liner is attached to the non-front side of the PVC profile with at least two self-tapping screws (screws) according to regulatory documentation (hereinafter referred to as ND). Distance from internal corner(weld seam) to the nearest installation location of the self-tapping screw should not exceed 80 mm.

The fastening pitch should be no more than: 400 mm for white profiles, 300 mm for other types of profiles, as well as for frost-resistant profiles.

5.7.9 Steel reinforcing liners must be protected with a zinc coating with a thickness of at least 9 microns in accordance with GOST 9.303.

Omissions and damage to the coating are not allowed.

5.8 Requirements for window devices

5.8.1 When manufacturing products, window devices and fasteners are used that are specifically designed for use in window systems made of PVC profiles.

5.8.2 The type, number, location and method of fastening of locking devices and hinges are established in the working documentation, based on the size and weight of the opening elements of the product, as well as the operating conditions of the window units. In this case, the distance between hinges and locking points, as a rule, should not exceed 800 mm.

5.8.3 It is recommended to fasten the hinges using self-tapping screws through at least two PVC profile walls with a total thickness of at least 4.5 mm or through one profile wall and a reinforcing liner. If it is necessary to drill holes for screws, their diameter should be equal to the diameter of the central core of the screw.

When the opening elements weigh more than 60 kg, as well as in balcony door blocks and reinforced products, it is recommended to fasten the hinges into reinforcing inserts.

5.8.4 It is recommended to use adjustable hinges in products, devices for tilt-and-turn opening that provide slot ventilation, as well as ventilation with an adjustable opening angle, using safety locks against accidental opening (including when the devices are positioned in ventilation mode).

To ensure a fixed gap between the lower profiles of the sashes and frames, it is recommended to use guides (impedance) pads, rollers or special fittings.

5.8.5 Locking devices must ensure reliable locking of opening elements of products. Opening and closing should occur easily, smoothly, without jamming. Handles and bolts of appliances should not move spontaneously from the “open” or “closed” position.

5.8.6 The designs of locking devices and hinges must ensure tight and uniform compression of the gaskets along the entire sealing contour in the recesses.

5.8.7 Window fittings and fasteners must meet the requirements of GOST 538 and have a protective and decorative (or protective) coating in accordance with GOST 9.303.

Window devices must withstand the loads and forces applied to them in accordance with GOST 23166.

5.9 Design requirements

5.9.1 Corner connections of PVC profiles of frame elements must be welded. The design strength of welded joints is given in the design documentation.

To strengthen welded joints in the corners of balcony block panels with a width of more than 800 mm, it is recommended to use welded polyvinyl chloride liners connected with screws to reinforcing liners. An example of installing liners is shown in Figure 7.

5.9.2 Impost parts are attached to adjacent PVC profiles of the frame (sash) using steel or plastic fasteners, screws or screws. Examples of fastening imposts are shown in Figure 8.

It is allowed to use welded T-shaped and cross-shaped connections of imposts. In this case, the strength of the connections must be no lower than the strength established for corner connections.

5.9.3 Corner and T-shaped connections of profiles must be sealed. It is allowed to seal the mechanical connections of PVC profiles with weather-resistant elastic gaskets. Gaps up to 0.5 mm can be sealed with special sealants that do not impair the appearance of the products and protect the connections from moisture penetration.

Drawing 7 - Insert for strengthening corner joints

Figure 8 - Examples of fastening imposts

5.9.5 Each glazing field must have holes for draining the cavity between the edges of the glass unit and the folds of the profiles.

Appendix A (informative) Terms and definitions

For the purposes of this standard, the following terms and corresponding definitions apply.

Profile system - a set (set) of PVC profiles and component elements combined into a complete structural system, documented in design documentation.

Profiles are parts of window blocks made by extrusion with specified shapes and cross-sectional dimensions.

Profile width is the largest dimension between the front outer and inner surfaces of the profile.

Profile height is the largest cross-sectional dimension of the profile in the direction perpendicular to the profile width.

The chamber is a closed internal cavity (system of cavities) of a PVC profile, located perpendicular to the direction of heat flow. The chamber may consist of a number of subchambers separated by partitions. Chambers and subchambers can perform various specified functions, for example, for installing reinforcement inserts or as self-ventilation channels.

Rebate is a part of the profile surface formed by the protrusion of one of its parts.

Clearance - the distance between the sash and the frame, established based on the conditions of normal functioning of locking window devices.

The narthex is the place where the sash connects with the frame bars (main narthex), with the impost (impost narthex) or with the sash (impostless, stulpovy narthex).

Overlap is a protrusion in the narthex assembly, formed by the protruding part of the frame (sash) and overlapping the sash (frame) by the size in the narthex under the overlay.

Reinforcing liner is a profile steel element installed in the internal chamber of the main profile to absorb operational loads.

A combination of profiles is a junction of mating profiles (for example, a frame profile - a sash profile with a glazing bead; an impost profile - a sash profile with a glazing bead; a sash profile with a bead and a glazing bead - a sash profile with a glazing bead).

The main profiles are the profiles of frames, sashes, imposts, and frames, which perform a strength function as an integral part of window and balcony door structures.

Additional profiles are profiles that do not perform a strength function as an integral part of window and balcony door structures.

Glazing beads (glass layouts) are additional profiles designed for fastening double-glazed windows.

Glazing beads can be manufactured with a co-extruded sealing gasket.

Connecting profiles (connectors) - profiles designed for interlocking window and balcony door frames with each other in structures consisting of two or more products. Connectors can connect frame profiles at different angles and are selected taking into account strength requirements.

Expansion profiles (extenders) - profiles designed to increase the height of the window frame profile.

Slabs are profiles designed for dividing the glazing fields of sashes.

Decorative overlays are overhead decorative profiles glued to a double-glazed window from the inside and outside and forming a false binding.

Flashings are profiles designed to drain water from the window structure.

Facing profiles - profiles for finishing window slopes (corners, platbands, trims, etc.). Cladding profiles can form various systems.

Controlled ventilation is the organization of ventilation of rooms with different air exchange rates due to the design solutions of products.

Self-ventilation is a system of limited air exchange through the channels of profile chambers or through climate valves built into window units in order to regulate the air humidity in the room and prevent condensation on the internal surfaces of the windows.

Durability is a characteristic of products that determines their ability to maintain performance qualities for a given period, confirmed by the results of laboratory tests and expressed in conventional years of operation (service life).
