Pultruded window profiles for best thermal properties
Stable, weather-resistant window and door profiles with lowest U-values made of maintenance-free GRP (glass-fiber reinforced plastic) individually manufactured for you in the pultrusion process according to your specifications


In the renovation of older buildings, GRP profiles serve as reveals in window recesses to compensate for unevenness and facilitate the installation of new windows.

Patio doors

Window profiles made of GRP are particularly suitable for large patio doors and windows. We see the production of profiles according to customer requirements as a special challenge.

The window profile

Excellent thermal insulation leads to a low U-value and often even a steel profile inside can be omitted: Thus, less heat escapes through the frame.
