Thermal Proofing

Table 3 of DIN 4108, part 4 /Arrangement of window frames in frame groups/…

Group 1: Window frames of wood, plastic and combination with wood, without special certification, where heat transfer factor of the frame is К< 2,0 W/(m2.K).

Group 2.1: Window frames of thermally isolated metal or concrete profiles, where where heat transfer factor of the frame is test-certified as 2,0 < К <2,8 W/(m2.K).

Group 2.2: Window frames of thermally isolated metal or concrete profiles, where where heat transfer factor of the frame is test-certified as 2,8 < К < 3,5 W/(m2.K).

Soundproofing according to DIN 4109

Depending on type of profile systems and glazing, soundproofing class 5 /45-49 db/ may be achieved.
