ARC-C70 / C80 Thermal
C70 and C80 are three-gasket, multi-chamber casement and tilt-turn windows. Wide PA66 thermal breaks and foam-filled chambers deliver Uw values down to 0.9 W/m²K — enough for Passive House components in Europe and ENERGY STAR Northern Zone in North America.
One profile family covers inward tilt-turn, outward casement, awning and fixed lights, so a single shop drawing set covers a full building.
