Abstract
An insulating spacer (10) 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 (14) the substrates (40, 42) as does the sealant (26) 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 (32). 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.
Claims
AMENDED CLAIMS
[received by the International Bureau on 2 May 1997 (02.05.97);
original claims 1-30 replaced by new claims 1-23 and 27-30 (5 pages)]
1. A composite spacer for spacing substrates in a glazing assembly comprising:
an insulating body having spaced apart sides, a front face and a rear face, each side including a recess therein open to said rear face, said rear face being adapted to face the enclosed space in the assembly, each said side having a first substrate engaging surface; and sealant material in each said recess forming a second substrate engaging surface coplanar with said first substrate engaging surface said sealant being in a form selected from:
i) a C-shape, the C-shape including both said recesses and extending over said rear face of said body, and
ii) recess-filling strips extending past said rear face of said body to cover the ends of a further layer, said further layer comprising at least one of a fluid barrier, and a desiccant-containing matrix
2. The composite spacer as set forth in claim 1, characterized in that said sealant is a C-shape and includes desiccant therein.
3. The composite spacer as set forth in claim 1 , characterized in that said sealant is in form ii) and said rear face is covered by a desiccant containing matrix.
4. The composite spacer as set forth in claim 2, further including fluid barrier means between said rear face and said sealant.
5. The composite spacer as set forth in claim 3, further including fluid barrier means between said rear face and said desiccant.
6. The composite spacer as set forth in claim 1 , characterized in that said body comprises foam.
7. The composite spacer as set forth in claim 6, characterized in that said foam comprises polyurethane foam or polysilicone foam.
8. The composite spacer as set forth in claim 1 , characterized in that said insulating body is selected from the group comprising EPDM and cork.
9. The composite spacer as set forth in claim 1 , characterized in that said front face is covered with a sealant layer.
10. The composite spacer as set forth in claim 1 , characterized in that said sealant comprises a butyl sealant.
11. The composite spacer as set forth in claim 10, characterized in that said sealant is a C-shape of butyl material.
12. The composite spacer as set forth in claim 1 , characterized in that said body comprises a T-shape with the arms of the T being adapted to proximate the outer edge of the assembly.
13. An insulated glazing assembly set forth in that said assembly includes a pair of substrates engaged with the spacer as characterized in claim 1.
14. A composite integral pre-formed spacer for use in an insulated glazing assembly, comprising:
a body of insulating material having opposed sides and opposed faces, each side having a portion of material removed therefrom
to provide a recess and projection, each said projection being adapted for sealing a respective substrate;
sealant material in each said recess coplanar with each said projection for sealing a respective substrate said sealant and recess being proximate the face of said body adapted to face the enclosed space of said assembly; and
a desiccant matrix separate from and positioned against said body and said sealant.
15. The composite spacer as set forth in claim 14, characterized in that said body comprises a foam material.
16. The composite spacer as set forth in claim 14, characterized in that said spacer is an integral, one-piece spacer.
17. The composite spacer as set forth in claim 14, characterized in that each said projection includes means for adhesively engaging a substrate.

19. The composite spacer as set forth in claim 17, characterized in that said means for adhesively engaging a substrate comprises pressure sensitive adhesive.
20. The composite spacer as set forth in claim 17, characterized in that said means for adhesively engaging a substrate comprises uncured material capable of adhesively engaging a substrate.
21. The composite spacer as set forth in claim 20, characterized in that said uncured material comprises uncured silicone.
22 The composite spacer as set forth in claim 20, characterized in that said uncured material comprises uncured foam.
23. A glazing assembly set forth in that said assembly comprises a pair of substrates engaged with the spacer of claim 14.
27. A one-piece 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.
28. A composite spacer as set forth in claim 27, including at least one additional layer selected from a fluid barrier and a desiccant- containing matrix.
29. A composite spacer as set forth in claim 27, characterized in that said foam body comprises an ultra-violet curable foam.
30. A composite spacer as set forth in claim 27, characterized in that said second material and said third material are selected from a group comprising polyurethane, butyl, polyisobutylene or mixtures thereof.
