Abstract: In the floor tile for double floor installations, the tile core has a floor covering on its top side, a metal plate on its underside and a lipping on its peripheral edge. The peripheral edge is here provided with a groove (9) which is to receive hot-melt adhesive (3), and the metal plate (8) has an upward edge (4) which grips around the peripheral edge, reaches up to the lower rim of the groove (9) and is flush with a first lipping (7). A second lipping (2), which covers the groove (9) and a part of the upward edge (4) of the metal plate (8), is located on top of the first lipping (7).
