Insulating-slabs and their use

Abstract

Freshly-formed hard-foam plastic slabs which are preferably susceptible to maximum shrinkage are used as a base for insulating masonry structures. Each slab is grooved and has raised portions (lands) between adjacent grooves. Fastening elements (pins) are dispersed over the grooved surface to secure a reinforcing web to the slab and maintain it at a substantially uniform distance therefrom. To insulate a masonry structure, such as a wall, the face of the wall is covered with such slabs, which are secured to the wall. The exposed surface of the slabs is then plastered with a material which permits the passage of water vapor therethrough. The applied coating of plaster fills the grooves on the slab surface and is thick enough to cover the reinforcing web. A suitable finish coat of plaster or paint is optionally placed over the initial reinforced plaster coating.
