Abstract: A method of controlling hazardous particulate material during the demolition of buildings containing such material in the form of a friable layer of paint applied to the surfaces thereof. The method includes coating the friable layer with a water-based, pressure-sensitive adhesive which penetrates into the friable layer and bonds with the hazardous material contained therein forming a substantially homogeneous mass which is non-friable. Subsequently, the building is demolished without removing the hazardous material, and the remains of the building are disposed of in any conventional landfill not restricted to hazardous material disposal.

Abstract: A prefabricated insulated panel includes a sheet-like face member and an insulating mat extending along one surface of the face member. Complementary male and female formations extend along opposed edges of the face member and are adapted to matingly couple adjacent panels to form a contiguously extending insulated wall structure. The face member has an upstanding flange which is offset from one of the edges of the face member and which cooperates with such edge to define a recess adapted to receive the insulating mat of the next adjacent panel therein. The flange is adapted to facilitate attachment of the panel to a support and in a manner aiding in preventing heat flow through the panel. Each panel has a side edge structure which is constructed and arranged to minimize heat transmission through abutting side joints of adjacent panels while, at the same time, allowing for expansion and contraction of the panels.
