In addition to energy efficiency, good sound insulation and comfortable lighting are important in the house. Plastic windows must be equipped with protective elements to prevent burglary attempts from the outside.

But in slightly more extreme circumstances, such as severe frost or heat, as well as direct sunlight (UV), it can fail. Becoming brittle in the cold and softening in the heat, it quickly becomes unusable if the window sash is actively used. But with the doors constantly closed (or constantly ajar, in micro-ventilation mode, for example), it will last quite a long time.

Installation depth In addition to their own heat-shielding properties, such frames allow you to install more durable fittings, thick double-glazed windows and additional contours of insulation and sound insulation. But the width of the profile does not necessarily indicate the number of chambers - there are profiles with fewer cavities, but with a width of 8 or even 9 cm. In terms of general thermal insulation properties, they are better than narrow multi-chamber ones - it is not the number of chambers that matters here, but their size and stock air in them. We can conclude that the greater the installation depth, the better the window in terms of thermal insulation and other characteristics.

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.

Decorated and white windows differ in a number of mechanical indicators. The laminated frame, especially in dark colors, is more heated by the sun. This necessitates the mandatory reinforcement of the profile, regardless of the size of the structure.

You should make sure that the seller has a certificate for PVC windows, you can additionally request certificates for the profile and other components of the window unit.

It is very convenient for welding, easily changes its shape when compressed by the sashes, quite firmly fills the junction area and seals the window under normal operating conditions.

Choice of accessories and equipment When choosing accessories for windows, you should pay attention to their material, colors and functionality. You can choose metal-plastic windows and order roller shutters, blinds, mosquito nets for them. If necessary, window sills, slopes and ebbs can be added to the package.

The product passport must contain all profile parameters, including resistance to low temperatures, or simply indicate the degree of performance. If it is written that the profile belongs to a normal or frost-resistant type, then you can buy without fear, it is designed for negative temperatures.

Most of them are made on the basis of high-quality float g
