For buyers choosing plastic windows, the most acute is the issue of choosing a profile for glazing. From some manufacturers you can hear that he has lost its former relevance, since now almost all enterprises use high -quality components. However, the profile has not only chemical and physical characteristics, it also has indicators designed by developers, which make an attractive one or another system. The characteristics of the stability of the profile for PVC windows must be proceeding from the climatic conditions existing in Russia. Due to constant temperature changes from severe frosts to a thaw, a low-quality profile can suffer significantly from heat to rains, so large companies that produce PVC windows try to go ahead of score. In the production of plastic products, it is better to take into account the borderline operating conditions – the climate of the north of the country, since under other climatic conditions such windows will “work” by 100 percent.
Western standards
Another guarantee that the profile for glazing will meet all the accepted standards is, oddly enough, its production in the West. In recent years, norms and European standards have become much tightened, and now even the simplest profile, for example, a German company, does not cost anything to go through our certification. The profile for plastic windows at least once a year is completely modernized. Manufacturers try not to lose their part of the market and create new items to improve the image of their company.
Characteristics of the material
The profile used for glazing balconies should be high. Large openings are often required, and if necessary, large plastic windows are made. Due to the larger mass of the double-glazed window, the load on the profile increases, and it should easily tolerate the mechanical effect. The plastic from which the profile is made should be very soft by default, so a special reinforced insert is used. But it is difficult for a simple consumer to determine the required volume that allows you to maintain the shape of the window. Some manufacturers are trying to save on metal and allow deviations from the norms, hoping that the buyer will not notice the difference. The profile for glazing windows should be rigid, which allows you to form the design of the window and maintain the shape during subsequent operation.
