FEATURES + BENEFITS
OUTSTANDING THERMAL INSULATION
Uf : 1.1 – 1.4 W/m2K
Uw* : 1.3 W/m2K with double glazing (Ug: 1.0)
Uw* : 1.0 W/m2K with triple glazing (Ug: 0.6)
Uw** : 0.78 W/m2K with triple glazing (Ug: 0.5)
Three insulation levels:
• Optimized foam-filled insulation zone (ELVIAL I2 Technology) that ensures excellent isothermal flow of the window.
• Multi-chamber polyamide bars 34mm with glass fibers reinforcement 25%, (PA6.6 25 GF), for excellent insulation and extra rigidity.
• Specially designed central gasket with 5 cavities that covers all the polyamide surface, glazing gaskets with fins and perimetrical insulation with low density polyethylene, for effective heat transfer minimization.
