Abstract
An insulating spacer for use in glazing assemblies is provided. The spacer comprises a foamed insulating body and further includes a second sealant material. The insulating body partially contacts the substrates as does the sealant to provide a double seal when used in a glazing assembly. In other embodiments the spacer is a composite of foam, sealant material, rigid plastics and desiccated matrices. A further embodiment discloses an undulating foam spacer body for easy manipulation about the corner in glazing assemblies. The result of incorporation of the foam is a substantially energy efficient spacer and assembly.
Claims5
A composite spacer for spacing substrates, said spacer having opposed substrate engaging surfaces, comprising:
- a foam body, said foam body having a pair of first surfaces, each said first surface adapted for sealing engagement with a substrate;
- a pair of second substrate engaging surfaces of a layer of a second material different from said foam, said second surfaces being coplanar with said first surfaces of said foam body;
- and
- a pair of third substrate-engaging surfaces of a layer of a third material different from said foam material, said third surfaces being coplanar with said first and second surfaces and, whereby said spacer provides a pair of opposed substrate engaging surfaces each having a plurality of discrete component surfaces adapted to seal with said substrates and with said first surfaces in a position to be non-adjacent the space enclosed by the substrates on assembly, and with one of said layers extending in the plane of the assembled substrates.
