ABSTRACT:
An improved tip-in casement window has an outer frame, an inner sash, and elongated gasket strips. When the sash is assembled in the outer frame, an operatively continuous seal around the sash is created through the use of a downward facing gasket strip, thereby greatly increasing the insulative capability of a tip-in casement window.
