Thermofibra 2.0: a fully recyclable, more efficient PVC window frames

Replacing steel reinforcement in window profiles, Thermofibra 2.0 gets its extra strength and insulation from continuous glass fibres. They’re impregnated in a bath of PVC latex called Nanovin, later dried and gelated to create a tape which is introduced in a pultrusion die to reinforce the profiles. Thermofibra makes windows more sustainable by using up to 80% recycled PVC, making window frames with 18% better thermal insulation, and 25% lighter. And the profiles are fully recyclable.
