High R-value insulated building panel with integrated weather resistant barrier

1. An energy efficient insulated building panel comprising:

an insulation layer;

a rigid sheathing material; and

a weather resistant barrier;

wherein the panel includes a drainage plane;

wherein the insulation layer includes a foam insulator wherein the foam insulator includes polyurethane;

wherein the polyurethane foam insulator is self-adhered to the sheathing material;

wherein the panel does not include a separate adhesive bonding the polyurethane foam insulator to the sheathing material;

wherein the panel does not include a stud;

wherein the panel includes a corrugated, ridged, or grooved surface;

wherein the weather resistant barrier is wrapped or layered on the corrugated, ridged, or grooved surface;

wherein a gap between the weather resistant barrier and the corrugated, ridged, or grooved surface defines the drainage plane; and

wherein the polyurethane foam insulator has a flame spread value between about 0 and about 25 as determined by the ASTM E84 procedure and a smoke developed value between about 0 and about 450 as determined by the ASTM E84 procedure.

2. The panel of claim 1 , wherein the polyurethane foam insulator includes an R value between about R15 to about R72.

3. The panel of claim 1 , wherein the polyurethane foam insulator includes an R value between about R25 to about R72.

4. The panel of claim 1 , wherein the sheathing material includes at least one of a gypsum material, a magnesium oxide material, or a cementitious material.

5. The panel of claim 1 , wherein the sheathing material includes gypsum, wherein the panel further includes a fluid air barrier membrane.

6. The panel of claim 1 , further including a gypsum sheathing board, wherein the gypsum sheathing board further includes an ultraviolet resistant membrane.

7. The panel of claim 1 , further including at least one multi-laminar edge, wherein the at least one multi-laminar edge includes a male joint and a female joint, wherein the male joint is configured to connect to a female joint of a second insulated building panel.

8. The panel of claim 1 , further including a reinforcing member, wherein the reinforcing member includes a multiplicity of holes to receive the polyurethane foam insulator, wherein the reinforcing member is embedded in the polyurethane foam insulator.

9. The panel of claim 1 , further including a reinforcing member, wherein the reinforcing member includes a plurality of channels, wherein the plurality of channels includes at least one of a thread rod channel, a slotted channel or a framing channel.

10. The panel of claim 1 , wherein the panel is a seamless corner wall panel, wherein the corner wall panel includes a continuously insulated seamless corner and a double rail mating alignment component.

11. The panel of claim 1 , wherein the sheathing material and the weather resistant barrier are a single layer, wherein the weather resistant sheathing layer includes a fiber-reinforced plastic.

12. The panel of claim 1 , wherein the polyurethane foam insulator further includes a refrigerant, wherein the refrigerant includes a hydrofluoroolefin.

13. The panel of claim 1 , further including cross-laminated timber, wherein the sheathing is configured to attach to the cross-laminated timber.

14. The panel of claim 1 , wherein the panel includes a roof panel, a skylight panel, a bead panel, or a ridge panel.

15. The panel of claim 1 , wherein the corrugated, ridged, or grooved surface is a surface of the sheathing material.
