ABSTRACT:
A thermally insulated and connected window frame construction including first and second frame members having interfitting spaced portions with voids therebetween. An initial web portion connects the first and second frame portions. The inner surfaces of the frame members are coated with a bond inhibitor such as talcum powder. A plastic resin is applied into the voids between the interfitting frame portions. The resin is then allowed to "set" and following that the initial web portion is removed with the sole connection of the frame members being the resinous material with the frame members freely slidable upon the bond inhibitor during expansion and construction of the frame members.
The frame construction may be given structural integrity by inserting an elongated strip of material which extends into the voids between the frame members prior to the applying the resin, the strip of material is also coated with a bond inhibitor prior to the application of the resin.
