Abstract

A hermetically sealed multiple glazed window unit containing an air space dehydrator element comprising a desiccant material dispersed in a matrix of moisture vapor transmittable material.

Claims

2. The multiple glazed unit of claim 1 wherein at least one of said rigid sheets is comprised of glass.

3. The multiple glazed unit of claim 1 wherein both of said rigid sheets are comprised of glass.

4. The multiple glazed unit of claim 1 wherein the spacer-dehydrator element comprises separate spacer and dehydrator elements, the dehydrator element comprising said desiccant dispersed in said matrix.

5. The multiple glazed unit of claim 1 wherein the matrix is an elastomer.

6. The multiple glazed unit of claim 1 wherein the matrix is an elastomer and the desiccant is a powder which is dispersed in the elastomer.

7. The multiple glazed unit of clAim 1 wherein said moisture vapor transmittable material has a water vapor transmission of above about 15 gm./24 hr./1 sq. meter/mil at 100*F., 90% R.H.

8. The multiple glazed unit of claim 1 wherein said moisture vapor transmittable material has a water vapor transmission of above about 40 gm./24 hr./1 sq. meter/mil at 100*F., 90% R.H.

9. The multiple glazed unit of claim 1 wherein said moisture vapor transmittable material has a water vapor transmission of above about 50 gm./24 hr./1 sq. meter/mil at 100*F., 90% R.H.

10. The multiple glazed unit of claim 1 wherein said moisture vapor transmittable material comprises a flexible material.

11. The multiple glazed unit of claim 1 wherein said desiccant material comprises an adsorbent material.

12. The multiple glazed unit of claim 1 wherein said moisture vapor transmittable material comprises a block copolymer of styrene-butadiene rubber.

13. The multiple glazed unit of claim 11 wherein said adsorbent material comprises a zeolite.

14. The multiple glazed unit of claim 13 wherein said zeolite comprises a crystalline metal aluminosilicate.

15. The multiple glazed unit of claim 14 wherein said moisture vapor transmittable material comprises a block copolymer of styrene-butadiene rubber.

16. The multiple glazed unit of claim 1 wherein said moisture-resistant material is air impermeable.

17. The multiple glazed unit of claim 1 which further includes a moisture-resistant material extending between said opposing surfaces and said spacer-dehydrator element.

18. The multiple glazed unit of claim 1 wherein said moisture-resistant material extends across the adjacent peripheral edges of said rigid sheets.

19. The multiple glazed unit of claim 1 wherein said moisture-resistant material is a thermoplastic material.

20. The multiple glazed unit of claim 1 wherein said moisture-resistant material is a curable material.

21. The multiple glazed unit of claim 1 which further includes a metallic member extending in circumscribing relation about the periphery of said unit.

22. The multiple glazed unit of claim 1 which further includes a synthetic plastic member extending in circumscribing relation about the periphery of said unit.
