The CT70 vinyl windows with aluminium cladding on the outside include 70 mm thick 5-chamber profiles by the renowned German manufacturer Schüco. The outside aluminium cladding completely matches the design of the vinyl profile and protects the window against weather and damage. The windows are suitable for use in new construction and renovated buildings. The energy efficiency of the profiles is medium class, but by installing better insulated glazing, the windows can also be used in low-energy buildings (window Uw value up to 1.0 W/m2K).
