Casement Windows

A traditional and time proven window format, First casement or side-opening windows catch the breeze and direct air inwards. In exposed positions they may need to be secured with a restrictor. Shelter from above with projecting eaves or soffits will also provide further weather cover. First casements can be opened to 90 degrees with special window stays. Check out options for using hardware to create passive ventilation.
