FIN-Project Step-line Cristal

The Step-line Cristal semicomplanar (on the outside) variant of aluminum window, with PVC insulated core, wooden on the inside offers an entirely glazed surface and frameless shutter. Characterized by high thermal insulation, central profiles in multi-chamber PVC with median seal and optimized glass spacers, with triple glazing it reaches a thermal insulation Uw 0.84 W / m²K, and, with special elastic and heavy glass, Rw 42dB acoustic insulation. Finstral's intuition to use PVC in the central profile, not only thermo-acoustically insulating, but also recyclable, means true eco-sustainability! This window has the thinnest profiles in its category, permitting to have more natural light and a wider view, with an outstanding insulation.
