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 spaced parallel relationship attached on opposite sides of the frame in 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 presented 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. The glazing panel can be incorporated as a fixed window or as an operating window or door in an external building wall.

1. A fenestration sealed frame, insulating glazing panel having an integral generally planar frame that is formed by a number of rigid plastic framing profiles having interconnected ends that define corners of said frame, said plastic framing profiles being fabricated in a material that has a low heat conductivity compared to aluminum and a coefficient of expansion that is similar to that of glass;two glazing sheets arranged in spaced parallel relationship and attached to opposite sides of said frame to define therebetween a sealed insulating cavity; each said framing profile in section having an overlap portion that is overlapped by said sheets, said overlap portion of each said framing profile defining on opposite sides thereof an elongate seat to receive a marginal edge region of a corresponding one of said glazing sheets; each said framing profile having a front face that is located between said elongate seats thereof and is directed into said cavity; each said elongate seat being of L-shape in cross-section and having first and second sections that are parallel to a major surface and to an edge surface respectively, of an associated one of said glazing sheets, said glazing sheets being adhered to said first and second sections of each of said seats by a structural sealant material that exhibits thermosetting properties; and a cavity perimeter seal forming a continuous seal between said glazing sheets around the periphery of said cavity.
