Abstract

A material for covering a surface of a home or building is provided in the form of a flexible laminate having a fastening side comprising a sheet-form fastener component, and an opposite side formed by a sheet of paper laminated to the fastener component to increase the dimensional stability of the fastener component for covering and fastening over a wide area. The fastener component can have either hooks or loops. The laminate is particularly useful for laying flooring with low backlash between adjacent pieces.

Claims (62)

1. A flexible building construction laminate having

a fastening side comprising a sheet-form fastener component with hook-engageable loops defined by a knit or non-woven web material having a basis weight of less than about 4 ounces per square yard, and

an opposite side formed by a sheet of paper comprising a vapor barrier coating or resin film vapor barrier and adhesively laminated to the fastener component,

the paper significantly stiffening the web material against stretching in a plane of the laminate, the laminate having a Gurley stiffness of more than 500 milligrams, while

the paper is of such flexibility that it may be wound freely about a roll of less than one inch radius, such that the laminate remains sufficiently flexible to be rolled up for storage and transport.

2. The laminate of claim 1 wherein the sheet-form fastener component is in a laterally stretched condition as laminated to the paper.

3. The laminate of claim 1 wherein the paper has a lateral stiffness at least as great as that of 85 pound Kraft paper.

4. The laminate of claim 1 wherein the web material comprises a non-woven web of entangled fibers, the fibers forming a sheet-form web body stabilized in a condition of at least about 50 percent areal stretch.

5. The laminate of claim 1 wherein the web material comprises a non-woven web of entangled fibers, the fibers forming a sheet-form web body stabilized in a condition of at least about 20 percent areal stretch, in which hook-engageable loops extend in clusters from tightened entanglements within the web body, the entanglements being joined together by straightened fibers, at least some of the fibers having a fiber denier of less than 3.

6. The laminate of claim 1 wherein the web material comprises a non-woven web of entangled fibers and includes a binder resin anchoring hook-engageable fibers or yarns and constituting between about 20 percent and 40 percent of the weight of the material.

7. The laminate of claim 1 in roll form, with the fastening side directed inwardly.

8. The laminate of claim 1 wherein the paper has an exposed surface suitable for printing or writing thereupon.

9. The laminate of claim 1 wherein the knit or non-woven web material has a basis weight of less than about 2 ounces per square yard.

10. The laminate of claim 1 wherein the material comprises a lightweight knit.

11. The laminate of claim 1 having a Gurley stiffness of more than 750 milligrams.

12. The laminate of claim 1 having a Gurley stiffness of more than 1000 milligrams.

13. The laminate of claim 1 wherein the paper is of such flexibility that it may be wound freely about a roll of less than one-half inch radius.

14. The laminate of claim 1 wherein the paper is of such flexibility that it will droop at projection lengths of less than 6 inches in a free cantilever projection test.

15. The laminate of claim 1 wherein the paper is between 20 and 90 pound Kraft paper.

16. The laminate of claim 1 wherein the hook-engageable loops are nominally less than 0.075 inch high.

17. The laminate of claim 1 further comprising an insecticide.

18. The laminate of claim 1 further comprising a fungicide.

19. The laminate of claim 1 further comprising a rodent repellant.

20. The laminate of claim 1 wherein the paper comprises Glassine paper.

21. The laminate of claim 1 wherein the paper is coated with an antifriction coating.

22. A flexible building construction laminate having

a fastening side comprising a sheet-form fastener component with hook-engageable loops defined by a knit or non-woven web material having a basis weight of less than about 4 ounces per square yard,

an opposite side formed by a sheet of paper adhesively laminated to the fastener component,

the paper significantly stiffening the web material against stretching in a plane of the laminate, the laminate having a Gurley stiffness of more than 500 milligrams, while

the paper is of such flexibility that it may be wound freely about a roll of less than one inch radius, such that the laminate remains sufficiently flexible to be rolled up for storage and transport, and

an insecticide on one of the paper and the fastener component.

23. A flexible building construction laminate having

a fastening side comprising a sheet-form fastener component with hook-engageable loops defined by a knit or non-woven web material having a basis weight of less than about 4 ounces per square yard,

an opposite side formed by a sheet of paper adhesively laminated to the fastener component,

the paper significantly stiffening the web material against stretching in a plane of the laminate, the laminate having a Gurley stiffness of more than 500 milligrams, while

the paper is of such flexibility that it may be wound freely about a roll of less than one inch radius, such that the laminate remains sufficiently flexible to be rolled up for storage and transport, and

a fungicide on one of the paper and the fastener component.

24. A flexible building construction laminate having

a fastening side comprising a sheet-form fastener component with hook-engageable loops defined by a knit or non-woven web material having a basis weight of less than about 4 ounces per square yard,

an opposite side formed by a sheet of paper adhesively laminated to the fastener component,

the paper significantly stiffening the web material against stretching in a plane of the laminate, the laminate having a Gurley stiffness of more than 500 milligrams, while

the paper is of such flexibility that it may be wound freely about a roll of less than one inch radius, such that the laminate remains sufficiently flexible to be rolled up for storage and transport, and

a rodent repellant on one of the paper and the fastener component.

25. A flexible building construction laminate having

a fastening side comprising a sheet-form fastener component with hook-engageable loops defined by a knit or non-woven web material having a basis weight of less than about 4 ounces per square yard, and

an opposite side formed by a sheet of Glassine paper adhesively laminated to the fastener component,

the paper significantly stiffening the web material against stretching in a plane of the laminate, the laminate having a Gurley stiffness of more than 500 milligrams, while

the paper is of such flexibility that it may be wound freely about a roll of less than one inch radius, such that the laminate remains sufficiently flexible to be rolled up for storage and transport.

26. The laminate of claim 25 wherein the sheet-form fastener component is in a laterally stretched condition as laminated to the paper.

27. The laminate of claim 25 wherein the web material comprises a non-woven web of entangled fibers, the fibers forming a sheet-form web body stabilized in a condition of at least about 20 percent areal stretch.

28. The laminate of claim 27 , wherein hook-engageable loops extend in clusters from tightened entanglements within the web body, the entanglements being joined together by straightened fibers, at least some of the fibers having a fiber denier of less than 3.
