Recently, TROCAL engineers and technicians have developed the TROCAL 76 center seal, a modern, refined PVC-U window system with a depth of 76 mm. Yet, not only does its technical performance reach the highest points in thermal and sound insulation, but its appearance is a compelling argument. The slim profile of the sash and outer frame promote the growth of impressively large glazed surfaces. Not only is your entire living space filled with sunlight, it also conveys a wonderful sense of warmth. The gains from the sun’s heat help reduce heating costs.


The result of the perfect design is a PVC-U window system with significant thermal insulation. Even the heat transfer coefficient in the standard version is an optimal Uf value of 1.0 W (m²K). The TROCAL 76 also has an impressive 48 dB sound insulation when fitted with triple insulation glazing. Special functional glazing up to a glass thickness of 50 mm can also be installed.


Design your PVC-U window profiles the way you want. You have the choice between classic white PVC, our TROCAL DecoStyle laminate range and proCoverTec.


The TROCAL 76 offers you the maximum flexibility you need for your ideas, while delivering convincingly high cost-effectiveness.

Our green principle: energy-efficient windows, lead-free stabilizers in source material, and intelligent recycling concepts add extra sustainability.
