CS 86-HI is a multi-chamber system for windows and doors that combines aesthetic design, optimal stability and high thermal comfort. Due to the insulating skeleton strips, CS 86-HI achieves Uf-values down to 1.2 W/m²K, making this a highly energy efficient system. Flexible expansion strips in the door vents ensure stability in all conditions.

The system provides inside opening windows and inside & outside opening flush doors (up to 3 metres). Furthermore, CS 86-HI doors offer different types of floor connections to meet acoustic, thermal and water requirements.
