ALT W72 CW Windows
The ALT W72 CW window system is an outward opening casement window based on the standard W72 frame and transom profile. In the event of strong wind pressure to the window, the window sash is compressed against the frame. The system is internally beaded for security. The handle, lock and lock counterparts are in the “warm” zone of the window (from the internal of the building); the hinges (stays/scissors) are located in the “cold” zone of the window (from the external of the building).
