Constructive width: 70 mm.
Number of chambers: 5 pcs.
Windows, produced with the new VIVAPLAST 5-chamber system, may reduce the energy loss in a premise up to 47 % which makes them the perfect solution for both an entrepreneur and an end consumer.
After tests done on heat-exchange coefficient in their capacity of independent laboratory, the high heat insulation capacity of the 5-chamber PVC profile, produced by VIAS Ltd. was confirmed one more time, as it includes:
- heat insulation: Uf = 1.2-1.3 W/m2K (standard reinforcement )
- heat insulation: reinforcement with thermal break: Uf = 1.2W/m2K
- water tightness – 6A class
- resistance to wind load – C1 class
- air permeability – 4 class
- sound transmission class: Rw(C:Ctr) = 32 (-2; -5) dB
- burglar-proof: to class of resistance 3 (DIN V ENV 1627)
