Abstract
A structural panel includes a rigid foam core, a spray foam on an exterior surface of the rigid foam core, and a first outer skin on the spray foam. The rigid foam core includes a tongue portion along a first longitudinal side face and a groove portion along a second longitudinal side face. A second outer skin is also on the spray foam.
Claims11
A structural panel, including:
- a rigid foam core;
- a first spray foam on a first exterior surface of the rigid foam core;
- a second spray foam on a second exterior surface of the rigid foam core;
- a first outer skin on the first spray foam;
- and
- a second outer skin on the second spray foam;
- wherein the rigid foam core includes a tapered tongue portion along a first side face and the first spray foam and the second spray foam form a tapered groove portion along a second side face of the rigid foam core that is configured to accept the tapered tongue portion, and an entirety of the second side face of the rigid foam core is planar;
- further wherein the rigid foam core is exposed for a length of the first side face and for a length of the second face of the rigid foam core.
