Abstract

A fenestration sealed frame insulating glazing panel has an integral planar frame formed by four rigid plastic profiles interconnected end-to-end to define corners, the profiles having a low heat conductivity. Two glazing sheets are arranged in a spaced parallel relationship attached on opposite sides of the frame in a rigid manner by thermosetting adhesive to form an integral structure having an insulating cavity enclosed by the frame. The front face of each frame profile facing towards the cavity is covered by a low permeability sealant. The sealed frame glazing panel can include a third glazing sheet positioned in parallel between the first two glazing sheets and likewise interconnected at its perimeter to the frame to divide the insulating cavity into two parallel coextensive sub-cavities. The profiles of the frame can be made from structural plastic foam material, glass fiber, oriented thermoplastic, or various other materials of low thermal conductivity.
