Economy building panel
First Claim
1. An improved insulating building panel comprising an expanded cellular core with substantially parallel front and back faces,said core having first and second side edges with complementary stepped configurations with a first edge having a wider step than the second edge, andthin reinforcing strips bonded to the front face of said core adjacent said side edges with the strip on the first edge extending along the lateral step surface a distance substantially equal to the difference in width of said steps at said first and second edges.

Abstract
A low cost insulating panel for covering walls of existing structures has an expanded cellular core having complementary stepped side edges of differing width to define depressions in a combination of two panels. The panel has thin flat reinforcing strips along side edges extending upon a front face of the panel and therefrom into the stepped configurations at most to come in contact in the depression formed by two mating panels without extending to a back face of any panel.

- 4. The combination of two building panels with each having an expanded cellular core with front and back faces and first and second side edges, said side edges of each panel having complementary stepped configurations with the step of the first edge being wider than the step of the second edge, said panels being disposed in side-by-side relation with a first edge of one panel abutting a second edge of the other panel to define a single trough therebetween from the front faces of said panels, and reinforcing strips bonded to said panels along the first and second edges on the front face of each panel and together extending upon said edges no further than the depth and width of said trough.
