COR 70 Hidden sash TB

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 the drainage solution. Any element that breaks the visual harmony of the ensemble is discarded. Minimizes the aesthetic impact of the window components. Compatible with all the 70 mm frame depth systems. It features a gasket at the bottom of the frame to evacuate the water, replacing the face drainage. Facilitates window fabrication, Inward Opening allowing to place the base of the frame on the site itself.
