Claim 0:
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.
