Abstract

A multi-layer building material comprising a fibrous layer and a macroporous shielding layer affixed to the fibrous layer for mitigating abrasion of the fibrous layer. The invention envisages use of the building material to provide a breathable membrane in the vicinity of a bat roost.

Claims (36)

1. A multi-layer building material comprising a fibrous layer and a macroporous shielding layer affixed to the fibrous layer for mitigating abrasion of the fibrous layer.
2. The building material of claim 1 , wherein the fibrous layer comprises continuous fibres, optionally polymeric continuous fibres.
3. The building material of claim 1 or claim 2, wherein the fibrous layer comprises a spunbond material, optionally a polypropylene spunbond material.
4. The building material of any preceding claim, wherein fibres of the fibrous layer have a thickness of about 50 Î1⁄4ηι or less.
5. The building material of any preceding claim, wherein the material is liquid water impermeable and water vapour permeable.
6. The building material of claim 5, comprising a liquid water impermeable, water vapour permeable membrane supported or protected by the fibrous layer.
7. The building material of claim 5 or claim 6 having a hydrostatic head of at least 200cm and/or a moisture vapour transmission rate of at least 500g/m224hr.
8. The building material of any preceding claim, wherein the macropores of the macroporous shielding layer have a maximum dimension of about 20 mm or less, optionally about 15 mm or less, about 6 mm or less, about 4 mm or less, or about 2 mm or less.
9. The building material of any preceding claim, comprising an adhesive mesh layer bonding the shielding layer to the fibrous layer.
10. The building material of any preceding claim, wherein the shielding layer is an outermost layer.
11. The building material of any preceding claim, wherein the shielding layer comprises macropores defined by an exposed structure standing proud of the fibrous layer.
12. The building material of claim 10, wherein the structure covers less than 90% of a shielded area of the fibrous layer, with the rest of the shielded area being exposed through the macropores.
13. The building material of claim 11 or claim 12, wherein the structure comprises interlaced threads or strands.
14. The building material of any of claims 11 to 13, wherein the structure comprises a net defining a regular array of macropores.
15. The building material of claim 14, wherein the net defines macropores having a width of at most about 20 mm, optionally in the range of from about 0.1 mm to about 15 mm or in the range of from 0.5 to 6 mm.
16. The building material of any preceding claim, wherein the shielding layer has a thickness standing proud of the fibrous layer of in the range of from about 0.1 to about 3 mm, optionally in the range of from about 0.5 to about 2 mm.
17. The building material of any preceding claim, wherein the shielding layer comprises a polymeric material.
18. The building material of any preceding claim, wherein the shielding layer comprises one or more polymers selected from the group of: polypropylene, polyethelene, polyethylene terephthalate, polyester, polyvinylidene chloride, or a combination thereof.
19. The building material or any preceding claim, wherein the shielding layer is flexible so as to be capable of forming a roll.
20. The building material of any preceding claim, wherein the fibrous layer is prone to linting or fluffing on abrasion.
21. The building material of any preceding claim, wherein the fibrous layer is polymeric.
22. The building material of any preceding claim, wherein the fibrous layer comprises a non- woven material.
23. The building material of any preceding claim, wherein the macroporous shielding layer is affixed to the fibrous layer by adhesive bonding.
24. The building material of any preceding claim, wherein the macroporous shielding layer is affixed to the fibrous layer by intermittent bonding.
25. The building material of any preceding claim, being flexible so as to be capable of forming a roll.
26. The building material of any preceding claim, wherein the material is a roofing underlay.
27. The building material of any preceding claim comprising first and second ones of said shielding layer affixed on opposed exposed faces of the material.
28. The building material of any preceding claim comprising first and second fibrous layers sandwiching a microporous membrane.
29. Use of a building material according to any one of claims 1 to 28 to provide a breathable membrane in the vicinity of a bat roost.
30. A method of providing a breathable membrane in a roof or wall, the method comprising installing a building material according to any preceding claim in a roof or wall.
31. The method of claim 30, wherein the roof or wall comprises a bat roost.
32. The method of claim 30 or claim 31 wherein the building material is installed in a warm roof application or a cold roof application.
33. A method of mitigating abrasion in a fibrous layer of a building material, the method comprising: affixing a macroporous shielding layer to the fibrous layer.
34. The method of claim 33, wherein the abrasion is bat claw abrasion.
35. The method of claim 33 or claim 34 wherein the building material, fibrous layer and/or shielding layer is/are as defined in any of claims 1 to 28.
36. The method of any of claims 33 to 35, comprising providing an adhesive mesh layer between the macroporous shielding layer and the fibrous layer, and applying heat and/or pressure to the adhesive mesh layer to affix the macroporous shielding layer to the fibrous layer.
