Metal-plastic windows
Modern plastic windows have a lot ofadvantages. They do not require careful care, unlike wooden ones, and are much more reliable and durable. Compared to wood, they do not crumble, they do not need to be sealed and repainted. Thanks to them, the picture outside the window becomes clearer and clearer, and the noise of the street penetrates into the room not to such an extent. Their cost is much lower than the windows made of wood, manufactured with the same quality.Durability of PVC profiles
A huge number of laboratory testsshows that the white PVC window frames have the desired long life. Checks on various test benches, as well as the experience gained, confirm the positive results of laboratory testing, as a result of which the PVC profile has fully justified itself.
Experience with color profilesdemonstrated that if their painted surface does not have protection from the effects of environmental factors, then it loses color for several years. This is especially true for brown profiles. To avoid such problems today in Germany, painted PVC profiles necessarily have a protected front surface. Sometimes the protective layer is carried out by gluing a special film - lamination. Also, the color can be produced by applying a two-component acrylic lacquer.
Another important point that guaranteeslong periods of operation of color profiles, these are reasonable measures for ventilation of external chambers in order to prevent hot air from stagnating in them. After all, the temperature of the outer surfaces of dark profiles on sunny days can reach 70 ° C. If, with proper ventilation of the chambers, the outer surfaces are protected, the lifetime of the colored profiles will be measured in decades.
Resistance to the influence of atmospheric factors
Due to the long life and associatedWith this load (the influence of the sun, rain, snow, etc.), a very important factor is the provision of high PVC stability to climatic factors. Strength of solid PVC directly depends on the volume and the proportion of constituent components in it.
Both for processing a profile, and for itsresistance to climatic effects a huge role played by such components of PVC as stabilizers. Many manufacturers have used lead for many years as stabilizers, which, combined with traditional acrylate modifiers, ensures comfort in working with the profile and the stability of window systems to climatic influences, as well as respect for the environment.
