Abstract (en)

[origin: EP0909857A1] Holes (6,7) form channels through the brick, between which are connecting webs (8) The ratio between the width of the webs measured in the direction of the outside walls (2,3) and the width of the channels, measured in the same direction, is 1:1.3 to 1:1.8. Width of the webs is preferably 3.5 - 4.1 mm and the channels take up 55-60% of the brick cross section.
