S80 Passive - PVC S Series

The perfect solution for saving energy

Thermal insulation Uf
> 0,89 W/(m2K)

The use of unique aluminium profile rolling technology makes S80 Passive windows a steel-free profile system with outstanding thermal insulation. One decisive advantage of the maximum insulation PVC-U system is the material on the inside of the profile system – a high-quality aluminium alloy. The polished surface reflects a large percentage of the thermal radiation.

> Window system to passive house level for Uf values as low as 0.79 W/(m²K)

> Centre gasket system with three continuous sealing levels for the best possible protection against wind, rain and the cold

> Increased basic depth for added security and burglar resistance

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.
The window made of Alu Inside profile, which is fitted with heavy triple glazing, has a comparable weight as a window with steel reinforcement, which is fitted with lighter double glaze.
