COR 70 Hidden Sash: A Window That Feels Like Art
The COR 70 Hidden Sash has a sleek 66 mm sightline, like the 80 mm version.
It integrates the ARCH INVISIBLE handle, concealed hinges, and a drainage solution.
Elements that disrupt visual harmony are eliminated for a clean, modern design.
This system minimizes the aesthetic impact of window components for a seamless appearance.
It is compatible with all 70 mm frame depth systems for added flexibility.
A gasket at the frame's bottom replaces face drainage, ensuring efficient water evacuation.
The inward opening design simplifies fabrication and allows site-based frame installation.
