High insulation thermal break window system, with total face width of 110mm. The casement features an additional three-level thermal insulation zone, with a foam core of i2 technology that magnifies the isothermal curves at the casement’s profile and minimises heat transfer, while it also meets the requirements for maximum thermal insulation, soundproofing, security and impeccable sealing.

Concept System® 77 is a high insulating window system that meets elevated requirements regarding thermal insulation, stability and security. Anticipating on the thermal requirements, the insulation value (Uf) for the HI+ variant of this system goes down to 1.7 W/m²K for a standard opening window. The unique concept of the system makes it perfectly suitable for triple glazing and CS 77 even achieved the Swiss Minergie® component label.

The system’s performance regarding acoustics, water- and air tightness, but also for specific applications like Bullet – and Fire Resistance, meets the most severe European standards. Moreover, CS 77 windows are available in different burglar resistance levels (class 2 & 3) making it an extremely secure system.
