To be convinced of the quality and high consumer properties of plastic windows, you just need to read about their characteristics in the article brought to your attention and compare them with wooden structures. The text is far from advertising in nature - only objective information. The choice of priorities is up to the reader. Here you will learn how to choose plastic windows, and why some designs are better than others.
It will not be superfluous to visit the company's office in order to familiarize yourself with samples and supporting documents. As a rule, companies with at least five years of experience are distinguished by the presence of a license and operate their own production. Their product is certified and meets the requirements of GOST.
The ends of the double-glazed window are sealed, the air inside is dry and the glass does not fog up at any temperature inside and outside. In modern double-glazed windows, instead of air, an inert gas is sometimes pumped, most often argon. Its thermal conductivity is somewhat lower than air, but the cost is higher. Whether such a step is justified in terms of energy saving is still a matter of debate. But in relation to the price - manufacturers win unambiguously.
Metal-plastic windows have practically replaced wooden structures, since they are absolutely maintenance-free and durable. The choice of metal-plastic windows is a responsible task. Do not give preference to cheap designs. Saving on materials and accessories will negatively manifest itself already with the advent of the first cold weather. It is most expedient to address the issue of choosing windows to the professionals of TM Windows KORSA or independently study how to choose plastic windows, and when buying, start from your knowledge. The right choice of windows ensures that there are no drafts, fogging, freezing and many other problems that residents of houses and apartments face.
Metal strips are hidden inside the profile and act as a strength enhancer. Sometimes windows of a similar design are called metal-plastic, which is more true than just plastic or PVC. The function of metal inserts is very important to ignore.
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, see its products, etc. It is best to buy products from large manufacturers - high-quality equipment plays a lot in the manufacture of windows. Many small companies and workshops cannot afford to buy expensive cars, and therefore their products are somewhat worse.
Number of air chambers in windows Chambers are voids in plastic construction elements (profiles and double-glazed windows). How many cameras should be in a quality window? The answer to this question depends on the climate of the region where you live and the location of the apartment.
number of chambers in double-glazed windows A single-chamber double-glazed window is more suitable for regions located in a subtropical and temperate climate, houses located in quiet neighborhoods. A double-glazed window is the best choice with the best heat and sound insulation characteristics (provided that the profile is chosen correctly), a universal option for both city apartments and private houses, it can be used not only in temperate, but also in subarctic climates
PVC used for the production of profiles has a number of features that manufacturers are constantly struggling with: 1. 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 mamaximum dimensions of window structures. 2. Low coefficient of elasticity, but even at the factories it is leveled by the use of metal inserts and the correct calculation of the thickness of the inner walls, which are stiffeners. 3. Insufficient temperature stability and UV resistance. Manufacturers also learned to deal with this drawback by introducing special modifiers and stabilizers into PVC, which 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 emits a pungent 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.
The most common window profile width levels in Russia are 60 (from 58 to 62 mm) and 70 (from 70 to 76 mm). For most regions of our country, the second option is preferable.
