Abstract

A thermally insulative and waterproof barrier for protecting an exterior surface includes a plurality of generally rectangular flexible blankets in overlapping disposition. Each blanket defines a body and a peripheral margin about edges of the body, edges of the bodies of adjacent blankets (including the base layer) overlapping. Each body includes at least one base layer of thermal insulation and two cover layers of waterproof material. The cover layers are sealed together peripherally about the base layer to form the peripheral margin and exclude water from the base layer.

Claims

1. A seriatim assembly comprising:

(A) a substrate defining an exposed exterior surface;

(B) an intermediate layer of a thermally insulative and waterproof barrier for protecting said exterior surface, said barrier being disposed over said exterior surface and comprising;

a plurality of generally rectangular flexible blankets, each said blanket defining a central body and a peripheral margin about edges of said body, edges of said bodies of adjacent blankets overlapping, each said body including at least one base layer of thermal insulation and two cover layers of waterproof material, said cover layers being sealed together peripherally about said base layer in a substantially gas-tight relationship to form said peripheral margin and to exclude water and water vapor from said base layer; and

(C) an outer layer disposed over said intermediate layer and comprising a concrete slab.

2. The assembly of claim 1 wherein said blankets are disposed with adjacent blankets forming only a single pair of mutually overlapping edges.

3. The assembly of claim 1 wherein at least one of said blankets has all four edges overlapping the edges of other blankets.

4. The assembly of claim 1 wherein said peripheral margin of each said blanket is heat-sealed.

5. The assembly of claim 1 wherein said overlapping edges overlap by at least 1.5 inches.

6. The assembly of claim 1 wherein said overlapping edges overlap by not more than 4.0 inches.

7. The assembly of claim 1 additionally including grommets extending through said peripheral margin of each blanket, and securing means extending through at least some of said grommets for securing each said blanket to one of a substrate, said structural frame and another of said blankets.

8. The assembly of claim 1 wherein each said blanket is sufficiently flexible to be rollable into a generally cylindrical configuration.

9. The assembly of claim 1 wherein each said blanket has a thickness of not more than 1.5 inches.

10. The assembly of claim 1 wherein said thermal insulation includes at least one metallized surface of at least one cover layer.

11. The assembly of claim 1 wherein said waterproof material is sheet-like.

12. The assembly of claim 1 wherein said waterproof material is moisture-proof.

13. The assembly of claim 1 wherein said waterproof material is impervious to soil gas.

14. The assembly of claim 1 additionally including a plurality of fixation means extending through each said blanket body to fix the relative position of said base layer relative to said cover layers.

15. A seriatim assembly comprising:

(A) a substrate defining an exposed exterior surface;

(B) an intermediate layer of a thermally insulative and waterproof barrier for protecting said exterior surface, said barrier being disposed over said exterior surface and comprising;

a plurality of generally rectangular flexible blankets, each said blanket defining a central body and a peripheral margin about edges of said body, edges of said bodies of adjacent blankets overlapping, each said body including at least one base layer of substantially non-compressible thermal insulation and two cover layers of waterproof material, said cover layers being heat-sealed together peripherally about said base layer in a substantially gas-tight relationship to form said peripheral margin and to exclude water and water vapor from said base layer;

each said blanket being sufficiently flexible to be rollable into a generally cylindrical configuration and having a thickness of not more than 1.5 inches;

said blankets being disposed with adjacent blankets forming only a single pair of mutually overlapping edges, and at least one of said blankets having all four edges overlapping the edges of other blankets, overlapping edges overlapping by at least 1.5 inches and not more than 4.0 inches;

a plurality of fixation means extending through each said blanket body to fix the relative position of said base layer relative to said cover layers; and

grommets extending through said peripheral margin of each blanket, and adapted to receive securing means extending through at least some of said grommets for securing each said blanket to one of said substrate, a structural frame and another of said blankets; and

(C) an outer layer disposed over said intermediate layer and comprising a concrete slab.
