Casement Windows
Full ventilation and the tightest seal you can get.
Casement windows are hinged on one side and swing outward with a crank handle. When closed, the sash presses tightly against the frame for one of the best air-and-weather seals of any operable window type. When open, the entire sash acts like a scoop to catch passing breezes.
How casement windows work
A crank mechanism at the base of the frame swings the sash outward on a hinge. The compression seal engages as the crank tightens, creating an exceptionally tight closure.
