Abstract

A multipane window unit is provided in which a sash frame is formed having an integral spacing structure upon which glazing panes are directly affixed. The spacing structure is formed integrally with the sash frame at internal glazing surfaces. Adhesive can be affixed to the internal glazing surfaces to attach the glazing panes. In this manner, a rigid, structural sash frame can be formed prior to attachment of the glazing panes, thereby eliminating the need for using separately manufactured insulating glass units while obtaining similar and improved benefits.
