Cortizo 70

COR70 is a window and door system with a large width of the frame profiles 70 mm. The 35mm wide thermal break applied in the profiles provides very good thermal insulation parameters with Uf coefficient from 1.2 W/m2K. Perfectly designed aluminum profiles, a wide polyamide thermal break, hermetic EPDM gaskets and polyolefin foams placed around the glass allow for perfect adaptation to changing climatic conditions and achieving significant energy efficiency. The system allows you to design modern window construction solutions in many variants – windows (unopened, turn, tilt and turn), external doors and various types of shop windows.
