When masonry or wooden walls are insulated with hard-foam-slab insulation covered with plaster or mortar, reinforcement of the plaster or mortar can be omitted without incurring cracking if (a) the slabs are grooved, (b) the size and number of slab grooves have defined minimal values, depending on slab thickness, (c) the slabs have a residual shrinkage of at least 0.1 percent, (d) the plaster or mortar has a maximum plastic-resin content of 2.5 percent by weight and (e) the slab weight per cubic meter is, optionally, less than 20 kg per cubic meter.

One of a plurality of foam-plastic thermal-insulating slabs having: (a) a residual shrinkage capacity of from 1 to 4 millimeters per meter, (b) a finite thickness and (c) two major surfaces, one of which has rim portions and plural grooves of measurable and substantially uniform width and depth, the ratio of the slab thickness in millimeters to the product of the groove width in millimeters and the groove depth in millimeters being between 5:3 and 9:4, and being adapted for application to an outer wall of a building in juxtaposition to other similar slabs and for being secured to such similar slabs by a common unreinforced plaster coating covering their respective grooved surfaces and filling the grooves therein.
