GOST 30674 99 window blocks made of polyvinylchloride profiles. Basic standards in the field of production and installation of windows

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

This section contains only the current GOST for windows and double-glazed windows. Previously, other standards were in force and have been superseded by the following. You can download these documents for free.

Information about the date of introduction is given under each GOST for window blocks. Also shown are the previous window standard numbers that were in effect prior to the new regulations.

The legal and regulatory framework for plastic windows in our country is formed by almost two dozen GOSTs, most of which are reception of German and / or European standards, SNiPs and industry specifications, although it should be admitted that the package of 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 basic documents for the development of glazing designs for apartments, private houses, buildings, including specific premises (attics, balconies, loggias, bay windows, verandas) are SNiP 23-02-2003 Thermal protection of buildings, MGSN 2.04-97 Permissible noise levels, vibrations and requirements for sound insulation 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 general provisions for windows made of wood, PVC, steel, aluminum, and profile GOST 30674-99, to the development of which were attracted by KBE specialists from the Profine GmbH production group, despite being put into operation in one year have differences, although not contradictions, and therefore for plastic windows the basic document today is precisely GOST 30674-99 Window blocks made of PVC 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 obsolete and many manufacturers of profile systems of the status of branded products have long gone beyond the norms of domestic acts, of course, towards improving the mechanical and thermal characteristics of the profiles they produce. ... Some companies and production groups operate according to their own standards and / or technical 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 the appropriate glass units, makes it possible to reach the European level of thermal protection standards for translucent rigid PVC structures.

Similarly, today GOST 30778-2001 Sealing gaskets made of elastomeric materials for window and door blocks are morally obsolete, GOST 10174-90 Polyurethane foam gaskets for windows and doors, and, moreover, GOST 19177-81 Rubber porous sealing gaskets that do not cover the full range of modern seals for the contours of the recesses of plastic windows, as well as seals for sliding systems, which are mostly patented by manufacturers in recent years and are effectively used by assembly companies or welded onto a profile during its manufacture.

No less problematic in terms of information content and standardization have become GOST 30777-2001 Devices rotary, folding and swing-out for window and balcony door blocks and GOST 5087-80 Handles for windows and doors, since well-known manufacturers of accessories literally annually offer innovative design solutions for hardware hardware complexes by integrating modern electronic control systems into them, adapted to the new security systems for houses and buildings. Moreover, even mechanical sliding fittings for plastic structures for balconies, loggias, as well as parallel-exposed fittings for plastic windows are not regulated by national GOSTs at all, and so far Gosstroy is not working in this direction.

The regulatory framework for glass and glass units is in a somewhat better position, which is based on GOST 111-2001 Sheet glass, GOST 30698-2000 Tempered building glass, GOST 2486689 Glued glass units, as well as GOST 30733-2000 Glass with low-emission hard coating and GOST R 51136-98 Multilayer protective glasses, although there are still no domestic regulations governing selective glasses, self-cleaning glasses, curved glasses, etc. and insulating glass units with inert gas and vacuum, which are already being marketed in the USA and Japan, albeit in limited sizes. A GOST 30779-2001 Glass packs for construction purposes. The method for determining resistance to weathering and assessing durability does not at all form an integrated approach to testing modern double-glazed windows in all their diversity and differences in thermal and mechanical characteristics.

Methods for assessing the operational characteristics of window structures, including those made from PVC profile systems, are quite fully and almost in accordance with European standards are set out in GOST 26602.5-2001 Window and door blocks. Methods for determining resistance to wind load, 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 resistance to heat transfer. Many of these standards are copied from German DINs and this makes them conditionally relevant, although probably not for long.

The latest Gostroy standard for today is GOST R 52749-2007 Window assembly seams with vapor-permeable self-expanding tapes, in fact, duplicating GOST 30971-2002 Assembly seams for joining window blocks to wall openings, which were never implemented due to recommendation, and not the obligation of the normative provisions set forth therein. At the same time, the overwhelming majority of domestic companies, freelance installers and shabashniks' teams carry out the installation of plastic windows in the old-fashioned way with training blowing of mounting gaps with construction foam, and control over the implementation of the current GOST R 52749-2007 is traditionally declarative for our country, but not real ...

GOST for plastic windows. The main guests when 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 should always be installed strictly in accordance 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, general information about window units, basic terms and their classification. It is used to install wooden, plastic and metal window and balcony blocks.

The standard is fundamental for a set of standards, designed for certain types of window block designs 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 blocks must necessarily 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.

Products of plastic windows made in accordance with GOST 23166-99 must consist of certain frame elements, such as boxes, sashes, canvases, vents, transoms. Corner joints of these elements of window frames are connected with glue and spikes, mechanical ties, welding or other methods. The standards provide design solutions that are mandatory for use in the production of corner joints for certain types of window products.

Constructive solutions of window blocks must necessarily provide for the ventilation of the premises using shutters, vents, transoms or ventilation valves. Experts recommend using devices for regulating the humidity and temperature regime in the design of products: self-ventilation systems and climatic valves.

The design of the product should provide for the possibility of installing and using several circuits of sealing gaskets located in the porches for window blocks intended for operation in poorly heated rooms. The designs of window products should take into account the possibility of replacing glass, gaskets, various window devices and glass units, without violating the integrity of the product.

GOST 30674-99 PVC windows

This GOST defines the areas of application, classifications of windows and their functions. This standard also defines the technical requirements that apply to plastic windows. This standard is intended for control during the manufacture and installation of window and balcony door blocks made of PVC profiles according to 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 brands of the product can be used depending on the available operating conditions, taking into account SNiP and the regulatory requirements of GOST 23166.

Compliance with the requirements of this standard is mandatory.

Products are classified according to GOST 23166, the options for their design and the type of surface finish may be different for PVC profiles.

As you know, window blocks are subdivided into 1-4-chamber, depending on the design of the PVC profile. Products are also divided according to the type of finish they are white, dyed in the mass, laminated and have a co-extruded front coating.

When placing an order for the supply or manufacture of individual window products, you should indicate the design options in accordance with GOST, include a description of profile structures and double-glazed windows, drawings indicating the opening schemes, describe the types of window devices, determine the requirements for the external appearance of 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, 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, which are welded from PVC profiles, reinforced with steel inserts. In window profiles, imposts are fixed in frame elements by welding or mechanical connections. The design of products, with the exception of unheated rooms in accordance with GOST, includes two or more rows of sealing gaskets in the vestibules.

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

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

Instructions

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

So: the biggest challenge is sizing your future windows correctly. 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 getting out of their deadlock. Therefore:

1. Rule # 1:

The worker who takes measurements must have an excellent spatial imagination and an analytical mindset, he must be well acquainted with the design of future windows, as well as have personal experience in installation. Believe me, a combination of all these qualities may not so often occur. They are also not so easy to educate, so most often they have to make do with less requirements, hoping at random, and the problems that often arise have to be solved already in the working order (for several years). What should be taken into account by the measurer so that the whole enterprise does not simply fly into the chimney, and the installers do not spend the night at the facilities?

2. Rule # 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 less than the outer dimensions of the opening so that it does not fall out. But how much more this already depends on a large number of difficult to predict factors, which we will discuss below.

3. Rule # 3:

You should never forget to clarify whether the outlines of the existing opening will be preserved from the outside for the next visit. After all, old plaster can be removed from it, lining can be sewn, an additional row of bricks can be laid, or a team of builders will generally expand it to incredible sizes without any prior notice.

4. Rule # 4:

It is also necessary to take into account the factor that the window opening may be very skewed (this is especially true for panel houses). All this can lead to an increase in the size of the windows 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 the outer size of the window opening by about 35-40 mm in width and 12-18 mm in height. There are several ways to do this: you can increase the overall dimensions of the window box, or you can expand your window with additional profiles that snap onto the box.

5. Rule # 5:

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