The SI82 Alu Inside TOP ALU vinyl/aluminium window features energy-saving 7-chamber profiles that support the insertion of PUR insulation foam. The outside aluminium cladding completely matches the design of the vinyl profile and protects the window against weather and damage. The products boast superior thermal performance and can be installed in better low-energy and even passive buildings (window Uw value up to 0.66 W/m2K).
Aluminium reinforcing profiles give the product structural stability and positively impact its thermal characteristics.
