How to determine the quality of a profile

How to determine the quality of a profile The first thing to pay attention to when buying Windows is the appearance of plastic. If the window is not laminated with decorative film for wood, the type of material will tell you a lot. High-quality polyvinyl chloride is a monolithic material, completely smooth, uniform color. If it shows spots, or, worse, small or large grains it is a fake, which is not worth buying in any case. I recommend ordering European Windows https://glawindows.com/ There are no completely low-quality Windows on the market now there are a lot of companies offering Windows of their own production and only one-day firms can afford to work with cheap materials. Before ordering Windows, you need to find out as much as possible about the company's reputation, view its products, etc.it is Best to buy products from major manufacturers a lot of high-quality equipment plays in the manufacture of Windows. Many small companies and workshops cannot afford to buy expensive cars, so their products are somewhat worse. The profiles of the frame are slightly different between them. There are separate designs for load-bearing racks, flaps, crossbars). In any case, profiles from the same manufacturer are used for a single window, which are cut at the factory to the required length and assembled into a single structure. The elements are joined by special welding or mechanical hardware. PVC used for the production of profiles has a number of features that manufacturers constantly struggle with: 1. A sufficiently high linear expansion reaching several millimeters per meter of length. In order to compensate for this phenomenon, it is necessary to leave special gaps, use reinforcement and correctly calculate the number of fasteners. The same feature of the PVC profile limits the maximum dimensions of window structures. 2. Low coefficient of elasticity, but even in factories it is leveled by the use of metal inserts and the correct calculation of the thickness of the internal walls, which are the stiffeners. 3. Insufficient temperature resistance and UV resistance. Manufacturers have also learned to deal with this disadvantage by introducing special modifiers and stabilizers that preserve the color and structure of the material. In high-quality Windows, such additives serve no less than the entire structure. They are, in most cases, completely harmless to humans. But if the frame gives off a sharp smell that does not disappear for a long time-do not buy this window. It used lead or cadmium, or even more dangerous chemicals, instead of harmless zinc and calcium.
