Abstract:
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.
