Abstract

Building materials such as structural panels, beams, roof decking, and flooring panels, are packaged within a protective layer including a sublayer of a polymeric material that can be applied at the factory. The protective layer protects the underlying building materials from exposure to weather and potential damage due to handling during shipping, at a job site, and which can be left in place during construction, thus eliminating the need for temporary protective measures covering the building materials. The protective layer may have additional properties such as breathability, fire resistance, and sound absorption. The protective layer also may provide an underlayment such as for flooring and roofing.

First claim

The invention claimed is:

1. A package comprising:
a plurality of building materials;
wherein each of the plurality of building materials comprises:
a core of a laminate or extrudate,

wherein the core has a first surface and a second surface; and

a plurality of protective layers;
wherein each of the plurality of protective layers comprises:
a polymeric sublayer and an adhesive sublayer;
wherein the polymeric sublayer comprises a film configured to encapsulate the core of each of the plurality of building materials, and includes at least one overlap portion that projects past at least one side edge of the core;
wherein the adhesive sublayer of each of the plurality of protective layers is in contact with the first surface of the core of each of the plurality of building materials;

wherein a peel strength of each of the plurality of protective layers in contact with the core of each of the plurality of building materials is 1 lb/in to 12 lb/in when tested according to ASTM D903,
wherein each of the plurality of protective layers is configured to remain in place after each of the plurality of building materials is installed in a building structure.

2. The package of claim 1 , wherein at least some of the plurality of building materials comprise roofing panels.

3. The package of claim 2 , wherein the polymeric sublayer comprises a thermoplastic polyolefin membrane.

4. The package of claim 1 , wherein at least some of the plurality of building materials comprise flooring panels.

5. The package of claim 1 , wherein the core of each of the plurality of building materials comprises a pre-fabricated laminate wood, a cross-laminated timber, or combination thereof.

6. The package of claim 1 , wherein the polymeric sublayer comprises a film comprising polyolefin, acrylic, thermoplastic, elastomer, polyester, cellular foam, aerogel foam, or a combination thereof.

7. The package of claim 1 , wherein the polymeric sublayer comprises a film having at least one property including fire resistance, insulation, impact resistance, breathability, ultraviolet resistance, water resistance, sound dampening, or combinations thereof.

8. The package of claim 1 , wherein at least some of the plurality of building materials comprise a tile or cement backing panel.

9. The package of claim 1 , wherein at least some of the plurality of building materials comprise a structural support, and wherein the protective layer further comprises a vapor permeable film material.

10. A package, comprising:
a plurality of building materials, each including a core having a plurality of side edges, a first surface, and a second surface;
a plurality of protective layers applied over the core of each of the plurality of building materials, each of the plurality of protective layers comprising a plurality of sublayers, including:
at least one polymeric sublayer; and
at least one adhesive sublayer;

wherein the at least one polymeric sublayer comprises a film configured to encapsulate the core of each of the plurality of building materials, and includes at least one overlap portion that projects past at least one side edge of the core;
wherein the at least one adhesive sublayer of each of the plurality of protective layers is in contact with the first surface of the core of each of the plurality of building materials;
wherein each of the plurality of protective layers is configured to remain in place after installation of each of the plurality of building materials in a building structure; and
wherein a peel strength of each of the plurality of protective layers in contact with the core of each of the plurality of building materials is 1 lb/in to 12 lb/in when tested according to ASTM D903.

11. The package of claim 10 , wherein each of the plurality of building materials comprise at least one of a roof deck panel, flooring panel, wall panel, and a structural support.

12. The package of claim 10 , wherein the core comprises a cross-laminated timber material, a laminated wood material, an extruded polymeric material, a cement-based material, or combinations thereof.

13. The package of claim 10 , wherein the at least one polymeric sublayer comprises a thermoplastic polymer membrane.

14. The package of claim 10 , wherein the at least one polymeric sublayer comprises a film having at least one property including fire resistance, insulation, impact resistance, breathability, ultraviolet resistance, water resistance, sound dampening, or combinations thereof.

15. The package of claim 10 , wherein the polymeric sublayer comprises a polyolefin, acrylic, thermoplastic, elastomer, polyester, cellular foam, aerogel foam, or a combination thereof.

16. The package of claim 10 , wherein each of the plurality of protective layers further comprises a fire resistant coating, a sound damping coating, a smart coating of an adaptive vapor control material, or combination thereof.

17. A roofing system, comprising:
a substrate;
a plurality of building materials positioned on the substrate;
wherein each of the plurality of building materials comprises:
a core comprising a laminate or extrudate and having a first surface and a second surface; and

a plurality of protective layers applied to the plurality of building materials;
wherein each of the plurality of protective layers comprises:
a polymeric sublayer; and
an adhesive sublayer;

wherein the polymeric sublayer comprises a film configured to encapsulate the core of each of the plurality of building materials, and includes at least one overlap portion that projects past at least one side edge of the core;
wherein the adhesive sublayer of each of the plurality of protective layers is in contact with the first surface of the core of each of the plurality of building materials;
wherein a peel strength of each of the plurality of protective layers on the core of each of the plurality of building materials is 1 lb/in to 12 lb/in when tested according to ASTM D903; and
wherein each of the plurality of protective layers is configured to remain in place after each of the plurality of building materials are installed on the substrate to form a roof.

18. The roofing system of claim 17 , wherein each of the plurality of protective layers further comprises a plurality of polymeric sublayers, each of the plurality of polymeric sublayers having at least one property including fire resistance, insulation, impact resistance, breathability, ultraviolet resistance, water resistance, sound dampening, or combinations thereof.

19. The roofing system of claim 17 , wherein each of the plurality of protective layers further comprises a fire resistant coating, a sound damping coating, a smart coating of an adaptive vapor control material, or combination thereof.
