CS 68 is a thermally improved three-chamber system for windows and doors that boasts the optimum combination of high insulation levels and optimal safety. The system is available in a variety of aesthetic shapes to match current architectural styles whilst offering all types of both inward and outward opening windows and doors. Double butt strips between the frame and sash and lowered drainage ensure superior wind and water tightness. Different inner and outer colours are possible.
