What else to look for when choosing plastic windows We talked about the main parameters of window structures - they should be taken into account when choosing in the first place. However, there are other characteristics that you should pay attention to in order to choose the best option in terms of thermal protection, sound insulation, durability and ease of use.

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

Intra-profile ventilation of PVC windows The method of ventilation of a room with closed sashes can be implemented in different ways. Some manufacturers install a slotted, folded or overhead ventilation valve in the PVC profile.

Three-chamber double-glazed windows are rarely used in PVC windows, as they are too thick and heavy. Modern technologies make it possible to achieve comparable indicators of thermal and noise protection in simpler ways.

What fittings for plastic windows are better? Professionals advise choosing only products from well-known manufacturers. Cheap low-quality analogues can quickly become unusable.

All profiles in exprof windows are equipped with reinforcing inserts with a thickness of 1.5 to 2 mm and have a protective zinc coating. Double-glazed window The main characteristics of the element: the thickness of the double-glazed window, the number of glasses and, accordingly, the chambers between the glasses, the presence of special glasses with heat-shielding coating.

What you need to know about double-glazed windows Expert's recommendations on how to choose a plastic window will certainly touch on double-glazed windows, as one of the most important parts. Like the frame, a double-glazed window is responsible for the level of thermal insulation and noise protection, but, in addition, the level of light transmission depends on the quality of the glass, which is the main function of the window.

Order a free call Selecting the type of sash opening When choosing plastic windows, you should decide on the type of sashes. They determine the functionality of the design and comfort during its operation. The type of sashes must be selected depending on the size of the structure, how many windows are in the room and whether there is a need for regular ventilation.

Which package is installed on the window largely depends on the seat on the frame, especially on one characteristic - the depth of the package. In good windows, the outer glass should be at least 15 mm from the front edge of the frame, which are overlapped by the profile rebate. For a mounting depth of the frame of 50 -70 mm, the seat of the double-glazed window ensures this distance is at least 18 mm. Few people pay attention to this parameter when buying, concentrating on the number of cameras and the width of the frame, but for heat-shielding properties it is very important - the smaller the seating depth, the faster the glass will start to freeze and mist.

How to determine the quality of the profile The first thing you need to pay attention to when buying windows is the appearance of the plastic. If the window is not laminated with decorative wood-like film, then the type of material will tell you a lot. High-quality polyvinyl chloride is a monolithic material, completely smooth, uniform in color. If spots are visible on it, or, worse, small or large grains, this is a fake, which is not worth buying in any case.
