A block (10) of non-capillary and insulation material has grooves (101-103) cut in its top side for receiving support planks (11-13) held in place by adhesive, so that a mass of insulation material (104-106) is formed beneath the planks in the block bottom region. For a large width block the supports (14) for it extend at right angles to the planks and are received by grooves cut in the bottom side of the block. |
