Abstract

An insulated composite board includes a first composite board including a first layer including a plurality of cellulosic fragments and a plurality of plastic fragments and an insulation layer including a first face coupled to the first composite board, the insulation layer comprising a foam material.

Claims (17)

1 . An insulated composite board comprising:

a first composite board including a first layer comprising a plurality of cellulosic fragments and a plurality of plastic fragments; and

an insulation layer comprising a first face coupled to the first composite board, the insulation layer comprising a foam material.

2 . The insulated composite board of claim 1 , further comprising an adhesive coupling the insulation layer to the first composite board.

3 . The insulated composite board of claim 2 , wherein the adhesive is a solvent mastic adhesive.

4 . The insulated composite board of claim 1 , further comprising a second composite board including a second layer comprising a plurality of cellulosic fragments and a plurality of plastic fragments, wherein the second composite board is coupled to a second face of the insulation layer.

5 . The insulated composite board of claim 1 , wherein the foam material is polyisocyanurate.

6 . The insulated composite board of claim 1 , wherein the foam material is directly coupled to the first composite board without the use of an additional adhesive.

7 . The insulated composite board of claim 6 , wherein the foam material is directly coupled to the first layer of the first composite board.

8 . The insulated composite board of claim 7 , further comprising a second composite board including a second layer comprising a plurality of cellulosic fragments and a plurality of plastic fragments, wherein the second layer is directly coupled to a second face of the insulation layer without the use of an additional adhesive.

9 . The insulated composite board of claim 1 , wherein the first composite board comprises a first facer coupled to a first side the first layer, wherein the insulation layer is coupled to the first facer.

10 . The insulated composite board of claim 9 , wherein the first composite board comprises a second facer coupled to a second side of the first layer.

11 . The insulated composite board of claim 1 , wherein the composite board includes an outer surface layer defining an outer surface of the insulated composite board and coupled to the first layer by a reinforced bonding layer, the reinforced bonding layer comprising polypropylene with uninterrupted glass filaments or polyester filaments extending longitudinally through the polypropylene.

12 . The insulated composite board of claim 1 , wherein the composite board includes:

an outer surface layer defining an outer surface of the insulated composite board;

an adhesive layer coupled to the first layer of the composite board; and

a fiberglass roving positioned between the adhesive layer and the outer surface layer.
