A floor slab (10) comprises a bottom layer (18) in the form of an insulating layer, a middle layer (16) and a top layer (14) forming a covering capable of being walked on. The middle layer (16) comprises webs (24) for supporting the top layer, and channels (26) through which a heat-transmitting medium, for example warm air, can be conducted. With the slabs according to the invention, it is possible to install in a simple way a floor air-heating system in which the warm air is distributed and passed directly through the channels (26) of the floor slabs. <IMAGE>
