Double standards
In the Russian market, assessment of the quality of windows is ambiguous. The criteria are blurred among buyers, and there is no unity among manufacturers. The window system passport helps standardize everything. It gives an understanding of how glazing will insulate heat, noise, and transmit light.
Enterprises that produce profile systems select materials independently and evaluate the quality themselves according to their own regulations. That is, several manufacturers may have different quality glazing made from the same materials. A different practice has developed in the world. Foreign manufacturers ensure that the properties of the product are independent of the country and place of its manufacture.
Benefits for buyers
Thanks to the introduction of a system passport, the consumer will be able to immediately visually evaluate the characteristics of different window models, since all the data will be clearly presented to him in the form of scales or diagrams. Intuitive markings on the stickers will simplify the selection procedure and save time. In addition, the buyer receives other equally important benefits:
- We guarantee that all declared parameters have been experimentally confirmed, and the windows will not present “surprises” when used in real conditions.
- Protection from scammers and unscrupulous manufacturers who are unable to consistently maintain high quality windows.
- A clear understanding of what exactly the money will be paid for.
- The ability to see and understand the difference between a cheap and expensive product.
- Confidence that you are purchasing the most suitable window model.
All of the above advantages ultimately transform into double savings. At the first stage, before installation, the buyer does not overpay for the product. And after installation, it saves on heating and air conditioning.
Certificate for glazing
For German enterprises, a window system passport is a key document when selling it. They check with him to control the quality of the product. Based on it, the developer produces a variety of prototypes of various standard sizes and conducts extensive tests in a specialized accredited institution. As a result of the tests, the developer receives a document for the profile system, which indicates all the consumer properties of the product and real windows.

When checking the quality certificate of PVC windows, enterprises must repeat the parameters specified in the document in mass-produced windows. It is required to manufacture window systems with the necessary documentation and components, and to conduct random tests of individual windows. Companies that have received approval from the developer can mark their products with a sign of compliance with European regulations and make a link to window passports. The information in them is often used by architects, investors, and consumers.
What characteristics are assessed in the passport?
The window passport is convenient because it does not contain secondary or difficult-to-perceive information. This allows buyers to immediately concentrate on studying the main parameters:
- Energy efficiency
- despite its importance, this indicator is still not taken into account by many buyers. As a result, installing new windows does not solve old problems - heat loss in the premises is still high. The new certification principles eliminate this shortcoming. - Sun protection
- windows have different light transmittance. In addition, many modern models are equipped with multifunctional double-glazed windows that retain heat indoors and reflect sunlight. There are several options for making such windows, and energy efficiency and reflectivity differ between models. The consumer should be aware of this immediately. - Sound insulation
– windows can be warm and let in the optimal amount of sunlight, but still remain uncomfortable. The reason for this phenomenon is the low level of sound absorption of models that are planned to be installed in a noisy place. Now buyers can immediately see how quiet their new windows will be. - Safety
– many customers remember this parameter only when troubles occur. The system passport will help insure against accidents and inform consumers about the level of burglary resistance of windows, the presence of protection against the opening of the sashes by children or gusts of strong wind, as well as fire resistance. This data is supplemented by reliable information about the actual service life of windows. - Design and care
- although aesthetic characteristics are perceived individually by everyone, experts decided to evaluate this parameter as well. However, in this case, their opinion is purely advisory. More important is information about how difficult it is to care for a particular window modification.
All of the above parameters depend both on the profiles with fittings and on the double-glazed windows for plastic windows, the technical characteristics of which directly affect the level of thermal and sound insulation of structures. The information provided in the passport comprehensively reflects the qualities of all components.
REHAU system passport
- Issued by the International Institute of Window Technology ift Rosenheim based on test results in Germany and Russia.
- The full version, unlike the short version, contains a list of test reports.
- Operates with data that relates to products sold by REHAU partners. They receive a certificate from a German concern and undergo annual control of the quality system, assembly of components, and condition of window systems before shipment.
- Classified depending on the profile width.
Benefits for window companies
This segment of the construction market is currently oversaturated with offers, so manufacturers are looking for effective opportunities to beat their competitors. As a result, issuing a system passport for their products will allow window manufacturers to:
- Immediately stand out in your region among competitors.
- Regularly confirm the quality of your products.
- Find out in a timely manner about shortcomings that need to be corrected.
- Present only competitive products on the market.
- Have a constant incentive to improve technology.
In fact, obtaining a system passport moves the company into the major league of window manufacturers, since the document will quickly become the main sign of elitism. The document will indicate that the company has everything necessary to pass strict certification.
Among buyers, trust in companies whose products will be sold with a valid passport will also quickly increase. After all, the information contained in the document not only insures the consumer against transactions with scammers, but also helps to choose the optimal model.
Certification of windows in Russia
The domestic passport for windows is similar to the German one. It is mentioned in the new GOST (currently in development), it will confirm the quality of profile systems. Certification in our country is initiated by the G3 association. The next edition of GOST is still being developed, and before its adoption, the REHAU concern, together with G3, manufacturers Roto and AGC, proposes to use ift Rosenheim passport data on the Russian market. This is possible thanks to uniform labeling of glazing products. It is based on five glazing characteristics:
- heat protection,
- soundproofing,
- design,
- Sun protection,
- safety.
The glazing properties in the system passport are reflected in pie charts. They allow you to evaluate finished windows and doors objectively. It is convenient to compare them with similar characteristics of fasteners, double-glazed windows, and plastic. To evaluate windows according to the “safety” criterion, not only burglary resistance is taken into account, but also the condition of the child protection mechanisms.
The window quality certificate is a source of objective information. The REHAU concern carefully checks manufacturers who mark profiles, double-glazed windows, and fittings. The document receives a window in which the quality of all materials meets G3 regulations. The document contains information about the configuration of the product, and the product is assigned a unique identifier. Using the passport, you can identify the entire cycle of manufacturing and implementation of the system. Certification of glazing helps customers get the windows they expect and buy quality products with experimentally confirmed characteristics.

A very important advantage of plastic windows and doors is the fact that they are easy to care for to maintain them in “working condition”. They practically do not need cosmetic repairs or any special maintenance, but there are some rules that, if followed, will extend the life of your products.
a) Fittings are one of the most important components of a window. It is necessary to protect the fittings from paint, construction plaster and other foreign objects. Do not insert foreign objects between the frame and the sash of a plastic window. Do not leave a plastic window open in strong winds. Do not load the sash with additional load. Do not allow the sash and window slope to collide. Do not allow the use of cleaning agents or detergents that contain acidic or other aggressive compounds that may damage the protective coating. All moving parts of plastic window fittings must be lubricated with highly purified household machine oil, which can be used in the appropriate temperature range.
b) The sealing gaskets should be checked for damage, paying attention to the sealing of the glazing. The seal must remain elastic. It is best to clean a plastic window with special products or warm soapy water. After the plastic window is washed, be sure to wipe the seal dry. Damaged gaskets must be replaced.
c) it is necessary to monitor the drainage holes. If they are clogged, rainwater can penetrate into the room; in addition, the conditions for drying the internal space of the sashes and frames will worsen.
d) you need to inspect the outer surface of the plastic window and, if necessary, clean it.

wow
What did you think! And then everyone go to hell! You didn't clean the dust from the window! The window broke because of this!
Oh lol. It’s only in universities that everything is according to GOST.
the one who after university does everything according to state regulations! then he rules and loses money! I am responsible for the market!
added “read more”, otherwise he’s ruined the blog feed with his sheets, you scoundrel.
