Patent ID: 8028353

Claim:
A swimming pool foam interlining device for use in a swimming pool structure having a backup wall about the perimeter thereof and a liner disposed thereon, said foam interlining device comprising: a foam web having two major surfaces, said foam web being an elongated web of polymeric foam material selected from a group consisting of an open cell foam structure, a closed cell foam structure, and a foam structure of open and closed cells, said foam web adapted for disposition between the uppermost portion of said backup wall and said liner; a mounting adhesive layer disposed on one of said two major surfaces of said foam web, said mounting adhesive being a high-strength pressure activated adhesive having sufficient tack to vertically adhere upon pressure activation to said backup wall, said mounting adhesive layer being an admixture of a thermoplastic elastomer, a tackifier resin and an amorphous diluent proportioned to provide, upon pressure activation, adequate adhesion, and wherein said mounting adhesive layer comprises about 10 to 50 percent by weight of a thermoplastic elastomer; about 5.5 to 10 percent by weight selected from a group consisting of ethylene, propylene, styrene, and mixtures thereof; about 20 to 50 percent of a tackifier resin; 15 to 50 percent by weight of an amorphous diluent; and, 0 to 2 percent by weight of a stabilizer; a self-skinned layer disposed on said major surface of said foam web opposite said mounting adhesive layer, said self-skinned layer releasably adherable to said adhesive layer enabling said foam interlining device to be rolled upon itself without a release sheet therebetween; and, said foam interlining device, upon installation on said backup wall, providing protection for said liner and thermal insulation for said swimming pool.
