New acoustic glazed units

/in

In order to confirm the best parameters of the manufactured isolated glass units, also this time the tests were conducted in the renowned IFT institute in Rosenheim.

The new isolated glass unit are attractive for many reasons:

  • They are insulation units with index of U=1.1 W/m2K (EN 6743), 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.
  • Thanks to the use of laminated glass:
    • hey are safe for users ? after they are broken they remain within their frames and thus they do not hurt people in the vicinity of the window,
    • They can temporarily prevent burglary,
    • They ensure efficient reduction of UV radiation and thus protect furniture and the interior walls from accelerated colour fading. At the same time they let inside the part of radiation which is responsible for the growth of plants and they do not cause their withering.

Currently the Company has 25 types of glass units on offer.
They provide weighted reduction index within the range of 31 and 51 dBA.
