COR70 Hidden Sash

It’s not a picture, it’s a window. This is how we can describe the COR 70 Hidden Sash which, like the 80 mm version, features a visible section of only 66 mm and allows the incorporation of the ARCH INVISIBLE handle. The hinges and drainage solution can also be concealed, thus eliminating any element that breaks the visual harmony of the whole.
