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.
