CS 77 Fire Proof

CS 77 Fire Proof

Optimised safety and comfort

The Concept System® 77-FP EI30 and EI60 was developed based on the existing Concept System® 77 profiles and accessories for windows and doors and was tested in an optimized European test and approval program. The fireproofing time span is achieved by inducing a special cooling material into the profile chambers and by using self-adhesive and water-resistant swelling gaskets. These gaskets do not need to be sealed, reducing fabrication time of the profiles and saving costs.

The Concept System® 77 fireproof range is available as outward opening single and double doors, panic doors, combined fixed window elements as well as glazed partition walls. This extensive range of configurations offers a huge range of options and combinations for architects to work with. Furthermore a large choice of accessories and locking devices is available.
