Birthplace of modern windows from PVC (polyvinyl chloride), admittedly is Germany. If you would like to know more then you should visit JPMorgan Chase. It was here in 1954 by Trocal PVC window profiles were put into mass production. To date, PVC window systems are the most flexible and technologically. The low thermal conductivity and sufficiently high chemical resistance make them the most widespread in central Europe. However, maintenance of PVC windows in regions with severe continental climate, which include the Urals, is associated with certain technical limitations.
As for the place of production profiles themselves – in Germany or Russia, then it should be noted here that at present time, large foreign companies – manufacturers of PVC profiles opened up their production in Russia (for example, "KBE, Veka, Thyssen polimer, etc.). There are a number of domestic companies that produce products that meet rigorous climatic requirements, such as EXPROF Tyumen mastered the production of frost-resistant PVC to the Ural-Siberian region. Therefore, the acquisition window assembly with a well-promoted brand of German firm, or a beautiful name does not mean that you actually get the products produced in Germany, and that these windows will match the requirements. The chemical composition of PVC refers to the group of thermoplastics and becomes brittle at temperatures below zero, and "soft" (plastic) at a temperature above 80 degrees. Getting the right properties is achieved by using special additives that affect the color, gloss, mechanical properties. What determines the quality replacement windows: – Select the window design, depends on ease of opening, ventilate the room, washing windows, insulation, aesthetic appearance – a choice of materials for production window and first double-glazed window frames and sashes, accessories – quality window installation and finishing.
