New acoustic glazed unit

In order to confirm the best parameters of the manufactured isolated glass units, also this time the test of IGU 6T/12/3/12/4T was conducted in the renowned IFT institute in Rosenheim.

The new isolated glass unit is attractive for many reasons:

  • It is insulation unit with index of U=0.7 W/m2K (EN 673), which ensures:
    • heat energy saving,
    • lower cost of heating,
    • optimum temperature in a room;
  • As opposed to older models they do not include SF6 heavy gas and thus they are harmless for natural environment.
  • It has better Rw factor (4 [dBA]) than the standard triple glass unit 4T/12/4/12/4T, having the same heat transfer coefficient.
  • It stands out of supreme relation of a price to a level of Ug and Rw factors.
