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.

High-quality translucent structures for many years protect the room from the scorching sun, cold and wind, provide optimal humidity in the room, perform protective and other functions. It is important to know how to choose the right plastic windows for an apartment in order to understand which characteristics you need and which ones are not worth paying for.

Fittings Window fittings are not only a handle, but also all the mechanisms located around the main sash, responsible for its movement, fixation incertain provisions.

Many opponents of PVC windows argue that wood is better for translucent structures, as it "breathes". Most likely, these people do not know about the existence of exprof Aero plastic windows, which allow air to pass through when the leaves are closed, providing a normal indoor climate without drafts, freezing and condensation.

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.

Profile A. External wall thickness from 2.8 mm, internal - from 2.5 mm. The best profile for residential buildings. Profile B. External walls from 2.5 and internal from 2.0 mm. Suitable for installation in heated and unheated rooms. Less resistant to mechanical stress.

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.

The stability of geometric shapes, the preservation of angles, the overall strength of the structure largely depends on the thickness of the partitions inside the frame. It is difficult to check the jumpers, one can only hope for the veracity of the information indicated in the product passport. This is another fact in favor of choosing windows from large manufacturers - the process is well established there and no one will falsify products, risking damaging their reputation and incurring millions in losses.

Seat for installation of a double-glazed window One of the most important parts of a metal-plastic window is a double-glazed window. Both the light transmission of the window and its heat-saving properties depend on its quality - one of the main characteristics, because of which plastic windows are selected.

Profile PVC profile is a frame, that is, the basis of a window structure, and therefore it must: have a high ability to retain heat: the minimum number of chambers acceptable for the climate of Ukraine is three (for example, "Bluevolution"). This option is ideal for glazing of balconies, private houses, including in the northern regions of the country, as well as residential and office premises in the southern part of Ukraine; differ in structural rigidity: a reinforced profile has excellent indicators of this criterion (metal frame thickness - at least 1.5 mm); comply with environmental standards: for high-quality PVC profiles, safe raw materials are used that guarantee stable technical characteristics, do not emit toxins when the temperature changes, have a stylish design: a profile with a uniform surface is a good base for an ideal window, and the trend is white PVC Salamander, not loses its glossy appearance even after decades.
