Thanks to thermal cutting, typical of composite materials, the pultruded fiberglass profiles are broadly applied in Klimahouse. They are used as thresholds for lift-slide fixtures and structural parts of doors and windows.
The Lambda value of glass fiber profiles is equivalent to 0.25-0.29. This makes it possible to produce structural and thermally insulated profiles in smaller sizes compared to aluminium profiles. The pultruded profile is thermally insulated and, therefore, a double or triple chamber is not necessary, as it happens with aluminium profiles.
A simplified design without polyamide inserts and the final profile appears to be more competitive.
