An insulating element for use in building walls comprises two rigid slabs preferably of brick, and interposed insulating material preferably of expanded polyurethane. The interposed insulation projects out along the periphery of the slabs and is embedded in a complementary recessed part in the insulation of the adjacent element, leaving an interval between the slabs which is filled with mortar in order to unite the slabs. Adjacent elements are pressed against each other during installation in order to reciprocally compress the insulation along the separation plane. The slabs are fed continuously, on edge, in spaced relation, between superposed conveyor belts, thereby to form a tunnel into which the polyurethane is fed and fills by expansion. The slabs are then cut apart by grinding and the insulation is cut along the midline of the slot thus produced, after which the elements are packaged.

Element for insulation of the external walls of a building, comprising two rigid slabs, and expanded polyurethane insulating material between the slabs which unites the slabs; the insulating material between the two slabs projecting out from between both of the two rigid slabs of the element along one edge of the element and being recessed between both of the two rigid slabs of the element along the opposite edge of the element in such a manner as to leave an interspace on each side of the element between the periphery of the rigid slabs of one element and the periphery of the rigid slabs of the adjacent elements when the insulating material of said one element abuts the insulating material of said adjacent elements, so as to receive mortar to connect the rigid slabs together, said insulating material being laterally outwardly exposed to said mortar in said interspace.
