Energy Efficient
CS77 is a thermally improved three-chamber system for windows and doors that uses fibreglass reinforced polyamide strips with ribs and/or hollow chambers to guarantee high insulation levels.
High Performance
A double butt strip between the frame and vent, and a lowered drainage, ensure superior wind and water tightness.
Versatile
CS77 is available in both Inward and Outward opening configurations, and different inner and outer colours are possible to match any environment. CS77 is also compatible with Ventalis – Reynaer’s innovative self-regulating ventilation system.
