Abstract (en)
[origin: EP0522549A1] In the case of a building block, preferably a brick (1-4) with vertical perforation, and preferably for masonry without cross-joint mortaring, the heat and/or sound insulation can be improved by providing at least one longitudinal groove (7) on both bearing faces at the same distances from one side face. The longitudinal grooves preferably have a rectangular cross-section and are arranged off-centre in the width direction. They may be filled with an insulating material, for example Styropor, or with concrete. <IMAGE>
