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.
Window profiles are produced according to EN 12608 SR (Europe) and GOST 30673-99 (Russia). According to the main indicators, they are almost identical. The main parameters are the thickness of the walls of the outer contour and internal partitions. According to these indicators, the profile is divided into three types - "A", "B" and "C".
If you come across a profile of a well-known company, for example, Rehau, KBE, Scamander, Mont Blanc, Veka, etc., then there is a high probability that the window will be of high quality. And if the design is made from the profile of an unknown factory, then it is hardly worth hoping for something decent. But it is impossible to focus only on the profile manufacturer - the window is a complex structure, the performance of which depends on the interaction of all elements - fittings, double-glazed windows, seals. Only by considering all the components in the complex, you can make a judgment about a particular window.

The surface of the profile is painted in various ways - acrylic coating, spraying, lamination under pressure. More expensive designs use metal or wood plates that are firmly fixed to the outside or inside of the frame. The decoration also concerns the very shape of the profile - the flat frames that have become familiar are gradually being replaced by rounded or more complex relief.
Slotted air ducts are a channel with a damper that opens manually or automatically. Seam valves have a more complex device with a damper that shuts off the flow at a dangerous level of draft. Overhead mechanisms are able to provide the maximum influx of fresh air, however, they significantly reduce the sound and heat-shielding properties of the window block, therefore they are not widely used.

Making measurements correctly To determine the exact dimensions of the future window, you need to call the measurer. Masters know how to take measurements correctly so that the profile is easy to mount, and in the future there will be no difficulties with operation. But if you want to know the approximate cost of the structure, you can do this work yourself or order a free measurement. To determine the width of the window, the opening is measured along the lower and upper edges, and then in the middle. how to measure the window correctly If the results will vary slightly, you should choose the smallest value. It is necessary to determine the height in a similar way, measuring the opening on the left, right and in the middle. When taking measurements, take into accountthe presence of a mounting gap, the size of which varies between two to five centimeters. Important! The frame size should always be smaller than the opening size. Measurements must be taken inside and outside the room. Having decided on the parameters of a metal-plastic window, its appearance, the number of wings, the presence of a transom, a window sill and a low tide, order a free call for individual production and installation of a window in Kyiv.

The more chambers, as well as the distance between their walls, the higher the noise performanceo- and thermal insulation. Two-chamber profiles are intended mainly for cold glazing, unsuitable for windows in heated rooms due to low thermal insulation.
