The properties of the double-glazed window determine the heat and sound insulation of the window block, as well as the degree of natural light in the room. Fittings play an important role in the usability and durability of the translucent structure. Details such as constipation, clamp, scissors, handle, bar are responsible for the possibility of opening the sashes in different ways.
There are several basic modifications of seals that differ in some properties and, of course, in price. The most common are: Thermoplastic (TPE). Thermopolymer (EPDM). Rubber. Silicone. Let's consider them in more detail.
Good installation Consider, even if you have purchased a window with a bunch of bells and whistles, you may install it incorrectly, as a result of which all the saved heat will go into the gap between the profile and the wall. Specify the qualifications and experience of the installation team, as well as the measurer.
If you see that the glasses in the double-glazed window are not parallel to each other, you can no longer buy a window. The same applies to all kinds of seals: they should fit snugly against the glass, there should not be any gaps. Sometimes the distance bar inside is designed for three glasses, although there are only two of them in a double-glazed window - this also worsens the characteristics of the double-glazed window and reduces all heat retention by the window to zero.
Replacing a double-glazed window with an energy-saving one Why choose KORSA Windows? The main requirements for the windows of apartment buildings are high noise insulation, safety and the possibility of ventilation of the premises. An important factor is the choice of components. Their quality affects the tightness of the doors and the operation of the fittings. Residents of the lower floors should choose plastic windows equipped with protective elements. If small children live in the apartment, it is necessary to have blocking elements from the inside.
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.
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.
What does a plastic window consist of? Profile is the main element of a window block. Its purpose is to combine other components into a whole structure.
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.
The system width of exprof profiles is 58, 60 or 70 mm, depending on the type of window and the number of chambers. The manufacturer's profile systems allow installing a double-glazed window up to 36 mm thick in a 58 mm profile, and up to 44 mm thick in a 70 mm one.
