CS 77 Aluminium Windows and Doors
CS 77 is a thermally-broken, multi-chambered system for windows and doors that offers excellent levels of security, weather resistance and thermal insulation.
The CS 77 system offers a comprehensive range of inward- and outward-opening window and door designs that are available in a range of three different styles, making it ideal for both traditional and contemporary building designs.
Combined with a huge choice of colours and finishes, and the ability to specify a different colour inside and out, the CS 77 is a truly versatile system that can be specified to compliment almost any home.
The fibreglass-reinforced polyamide strips and weather gaskets are designed with ribs and hollow chambers to achieve superior thermal insulation levels. A variant of the CS 77 has been awarded the coveted Swiss Minergie accreditation.
