cor 80 hidden sash
thermally broken
Elegant design in which the sash is concealed behind the frame, thus maximising the glazed surface and the entry of light. Added to all of this is the great thermal and acoustic performance prompted by the 45 mm thermal break and a glazing capacity of up to 51 mm that allows the installation of triple glazing.

cor 70 hidden sash
thermally broken
It could be a painting, but is a window. This is how we can describe the COR 70 Hidden Sash which, like the 80 mm version, has a sightline of only 66 mm and allows the incorporation of the ARCH INVISIBLE handle, concealed hinges and a drainage solution. Any element that breaks the visual harmony of the ensemble is discarded.
