N14 800

Casement System for Refurbishment

Developed for urban refurbishment projects, the N14 800 is particularly suited to historic centres, respecting traditional architectural styles. Its profile design allows solutions where the sash is flush with the frame on the interior side, while maintaining a more traditional appearance from the exterior.

Designed to preserve the architectural identity of buildings, the system simultaneously delivers high thermal and acoustic performance.
