More info

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.

Frame: 68 mm
Vent: 77 mm (window), 68 mm (flush door)
