First Claim
1. In combination, a rigid structural board, a foamed-in-place layer of rigid plastic insulating foam adhered to one face of said board and an elongate thin fastener-retaining strip disposed along the interface of said board and said rigid foam, said strip being substantially thinner than said foam layer, said board having a sufficient degree of porosity at said interface whereby said foam, being foamed-in-place, has portions extending into the pores of said board, and an elongate thin ridge formed in the outer surface of said foam directly outward from the location of said fastener-retaining strip.
