• the maintenance effort is high and the useful life is low.
• the extruded panels of a mixture of natural fibers and a polymer material are resiliently mounted on the substructure, so that the floor structure can also be used as a sports floor.

• the travel of the panels at a load of 80 kg is at least 2 mm, preferably at least 3 mm.
• a sufficient elasticity is provided in order to use the floor structure as a sports floor, for example, for ball sports, such as handball, basketball or other sports that otherwise take place only in sports halls.
• the panels preferably have a flat surface.
• the distance between two panels is at least on the long sides between 1 and 4 mm, in particular 2 to 3.5 mm in size. This ensures that in the event of rain, the water can drain between the panels and no larger puddles form.
• the gap between the panels is preferably set to less than 3 mm, since then a risk of injury from pinched fingers on the columns can be excluded.
• the advantageous effect is utilized that the extruded panels of a mixture of natural fibers and a polymer material expand after installation by absorbing moisture at most slightly, but otherwise remain dimensionally stable and not aufschdorfln, as is the case with wood-based materials.
• Each panel preferably has a groove on the longitudinal sides, to which at least one clip is inserted for attachment to the substructure. This allows the panels to be laid so that no fasteners protrude from the top.
