Our calculator will help you not to overpay for unnecessary design improvements. Select the main parameters: city of residence, type of premises, floor, heating system power, noise level. Then you will be able to determine the most significant design parameters, choose the width and chamber profile, standard or energy-saving double-glazed windows, configuration (window block type, number of sashes, opening method), select accessories and evaluate the cost of additional services.

For protection, comfort and beauty: how to choose plastic windows correctly The choice and purchase of metal-plastic windows requires the utmost responsibility, since the installed design provides for a fairly long service life - NOT a year or two, but decades! The modern market is replete with offers from both well-known and beginners offering ready-made engineering solutions, including non-standard ones.

The best plastic windows from a trusted company! What plastic windows are better? Objective customer reviews are an excellent guide for those who are confused in the abundance of companies and killed by colorful advertising promising incredible engineering solutions and all sorts of "chips".

The product range of the brand is in demand in almost 50 countries around the world. Products are certified and comply with European standards. In order to confirm the quality of the PVC profile from Salamander marked.

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.

PVC windows have recently appeared on the market, the cavities of which are not filled with air, but are filled with foamed heat insulators - expanded polystyrene, for example, or filled with fiberglass materials. Even with a relatively small number of chambers, their thermal insulation characteristics are much higher than air ones. But for now, their price is also higher.

It is because of the poor quality of fittings that buyers of PVC windows face the following problems: jamming of the sash; opening the window only with effort; blowing due to the inability to tightly close the sash; creak.

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.

Important! The reliability of the entire structure depends on the type of profile. They are made of PVC and at first glance look the same. Thermal insulation is provided by internal air chambers, and metal reinforcement guarantees strength. The higher the profile class, the greater the thickness of the outer wall.
