Abstract
An integrated multipane window sash is fabricated from a sash frame having an inside perimeter. An adhesive material is applied to the inside perimeter. The adhesive material has sufficient stiffness to function as a mounting structure for glazing panes, and may also function as a spacing structure. A first glazing pane is mounted to a first side of the adhesive mounting structure. A second glazing pane is mounted to a second side of the adhesive mounting structure or to a separate adhesive mounting structure. The adhesive mounting structure can be applied by co-extrusion with the sash profile, by post-extrusion, manually or automatically and can comprise, for example, at least one of a bead of adhesive, a preformed adhesive foam, a preformed adhesive tape, or a chemical sealant. The adhesive mounting structure can be combined with a desiccant.
