<p>The panel is made of insulating foam covered by stronger plastics material. It is for flat, or convex and concave, tiles, having locking portions along the sides and suspension lugs for the tiles at the side towards the latter. In addition to this row of lugs (4a), a further row of protruding ones (4b) is provided for the tiles (5) at the drainage side of the panel. The intervals between the lugs in the latter row are greater than or a multiple of those between the lugs in the first row. At the drainage side, there can be overlapping protrusions (40) on the panels, containing grooves by which they fit over lugs on the adjacent panel. <IMAGE></p> |
