CS 77 is a thermally improved three-chamber system for windows and doors that boasts the optimum combination of safety and comfort. Fibreglass reinforced polyamide strips with ribs and/or hollow chambers guarantee high thermal insulation levels.
The system is available in a variety of aesthetic shapes to match the current architectural trends whilst offering all types of both inward and outward opening windows and doors. A double butt strip between the frame and vent and a lowered drainage ensure superior wind and water tightness.
Different inner and outer colours are possible.
