GRP window and door profiles

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

Why you should choose a window profile from Fibrolux:

Can also be used in very cold or hot regions
due to the similar coefficient of thermal expansion as the glass pane, the profile can be used even in countries with large temperature differences between inside and outside. The high heat resistance ensures that the material retains its shape even at high temperatures.
Optimal thermal properties
the excellent thermal insulation leads to a low U-value and often even a stabilizing steel profile inside can be omitted: As a result, less heat escapes to the outside via the frame.
More light in the interior
the highly rigid material enables more filigree profiles and thus larger window areas: More light in the interior.
Low maintenance costs
GRP does not rot or corrode: no need for costly annual protective coating!
Durable investment
Due to good UV and weather resistance, the material has a long service life.

Fibrolux window profiles are ideal for:
Architects, window manufacturers, carpenters and joiners

Redevelopment

When renovating older buildings, GRP profiles are used as reveals in window recesses to compensate for unevenness and facilitate the installation of new windows.

Patio doors

GRP for window and door profiles - Fibrolux GmbH

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.
