CS 86-HI

Concept System 86 'High Insulated' aluminium window

Highly energy efficient

Concept System® 86-HI is a highly insulated inward opening aluminium window, which meets the highest requirements concerning safety and stability. The windows unique insulation concept not only ensures the extreme stability and elevated water- and air tightness, but also makes it perfectly suitable for triple glass applications.

The HI+ window variant can achieve an overall insulation value (Uf) of 1.0 W/m²K, making it one of the most energy-efficient windows available. CS 86 also achieved the Swiss Minergie® and Minergie-P® component label. 

With regard to safety, the CS 86-HI window can comply with burglar resistance classes 2 and 3, offering an ultimate level of security.

With a variety of possible combinations, CS 86-Hi is also compatible with CS 86 doors, CP 155 sliding system and CF 77 folding doors, making CS 86 aluminium window extremely suitable for all building types. 

Secured by Design option available 



Between countries, there are differences in how a window is placed into the wall. For more information on the usage of Reynaers BIM models, download the BIM guidelines.
