7-CHAMBER WINDOW SYSTEM WITH EXCELLENT THERMAL INSULATION
The seven closed air chambers inside the frame profile ensure maximum thermal insulation efficiency, which was previously unthinkable without costly additional measures. The patented, combined construction of plastic and aluminum reinforces the profiles so effectively that the steel reinforcements used in conventional profiles can be completely omitted. The removal of these “thermal bridges” significantly increases the insulation performance of these frame profiles.
● Uw value = 0.12 Btu/(h⋅ft2⋅°F)
● Patented plastic and aluminum construction
● Three levels of sealing
● Passive house certificate according to the ift Rosenheim testing laboratory
● High soundproofing and resistance to crosswinds and rain
● Suitable for low-energy and passive houses
