The ability of the window to withstand operational loads depends on the quality of the profile: opening and closing of the sashes; the weight of the double-glazed window; wind; precipitation; high and low temperatures; exposure to ultraviolet.
Price The total cost of a window unit depends on the dimensions, configuration, requirements for the design of the structure, the complexity of installation and some other nuances.
Why plastic windows are better Hermetic design prevents heat loss, which is especially important in houses with insufficient heating system capacity and apartments in which heating appliances are equipped with meters and temperature controllers.
Choosing windows for a private house When answering the question of how to choose windows for a private house or cottage, one cannot fail to note the importance of having energy-saving qualities. To save on heat carriers in the winter season, it is necessary to give preference to multifunctional double-glazed windows. The chambers of such a window are filled with an inert gas. This means that in winter the double-glazed window will keep heat inside the house, and in summer it will not let the street heat into the room. Such a window will cost more than usual, but the costs will justify themselves in the first season.
The most significant criteria are the recommendations of acquaintances or those who have already used the services of a particular company.

Choosing plastic windows: video instruction from an expert The video contains recommendations for working with a calculator on the exprof website, which will help you select all the important characteristics of a window structure in our configurator and send an application for production.
Certificate of conformity to GOST 30673-2013 for the profile, test reports for intra-profile ventilation, conclusions of laboratory tests for durability and resistance to climatic influences, as well as other documentation confirming the quality of the exprof profile, you will find in the appropriate section on the website.
After an approximate calculation on the site, you can choose the nearest offices where you can purchase the company's products, and send them an application that will take into account all the parameters you have chosen.
The role of air chambers in PVC windows Closed longitudinal air chambers in window frames play a dual role. This is an effective thermal insulation and reinforcement of the structure. External chambers, in addition, serve to remove condensate that forms inside the cavity due to the temperature difference in the room and outside. They are connected to the atmosphere at the bottom and drops of water simply flow down to the street. The presence of such holes has practically no effect on the overall level of thermal insulation.
