Often the floor level of two rooms is different. This difference in height can be a few millimetres, but sometimes more than a centimetre. In this case, you either need special adapter profiles to bridge the gap between the two rooms or you make do with lift-up blocks. Lift-up blocks are one way of compensating different levels between two rooms. As the name suggests, these installation aids are small blocks that fit into each other, usually made of fibreglass-reinforced plastic.  LOGOCLIC also has so-called Champion-flex profiles in its range – these allow a height difference between two floor coverings or rooms of up to 23 mm.
