CLAIMS
1. A building block having cavities (12, 13) therein which contain a heat insulating plastics
material (14), c h a r a c t e r i z e d in that one side (11) of the block (10), wherein the cavities (12, 13) open, is partly covered by a panel (15) of a heat-insulating plastics material having a width which is less than the width of the building block to leave a region (18) for joint material (20) between the edge of the panel and the edge of the building block (10) extending in parallel therewith, and that the panel (15) is made integral with cores (16, 17) each of which is inserted into and substantially fills a cavity in the block.
2. A method of manufacturing a building block according to claim 1 having cavities (12, 13) which open in one side (11) of the block and contain a heat- insulating plastics material (14), c h a r a c t e r i z e d in that a unitary body of the plastics material forming a number of cores (16, 17) and a panel (15) interconnecting said cores which projects from the panel is inserted with said cores into the cavities in the block by exerting a pressure on the panel the width of said panel being adjusted to the width of the building block to leave a region (18) for joint material (20) between the edge of the panel and the edge of the build ing block (10) extending in parallel therewith.
3. A method according to claim 2, c h a r a c t e r i z e d in that the plastics material of the panel (15) of the unitary body (14) is removed along said surface to provide said regions (18).
