COR 80 Hidden Sash

Elegant straight-line design in which the sash is withcealed behind the frame, maximising the glazed surface and the entry of light. This is combined with high thermal and acoustic performance driven by a 45 mm thermal break and a glazing capacity of up to 51 mm, allowing the installation of triple glazing.
