COR 70 Hidden Sash

It is not a painting, it is a window. This is how COR 70 Hidden Sash can be described: like the 80 mm version, it has a visible section of only 66 mm and allows the ARCH INVISIBLE handle to be incorporated, while the hinges and drainage solution can also be withcealed. In this way, any element that could disrupt the visual harmony of the whole is removed.
