Thermal insulation

Thermal insulation of windows is quantitatively defined by the heat transfer coefficient U(k) (W/m2K). This coefficient represents the amount of heat that is transferred through 1m2 of a building element in one hour.

Soundproofing

The sound insulation of the window is determined by the insulation power R, which is shown by a diagram depending on the frequency in the range from 100 to 3150 Hz in one-third octave steps. Weighted sound insulation Rw in db is used for expression.

Security

In order to ensure maximum safety from external factors, safety fittings and triple-layer glass are required. On the other hand, protection against glass breakage or cracking is achieved by using a special type of laminated glass that remains in the frame when broken and does not fall apart.
