Raising a floor 80 mm before vinyl? Compare LIGHTHERM Drymix 250 with AAC block infill on weight, insulation, joints and site fit, with a worked 100 m² example.

Compare the conventional XPS board and pour-in approach against Vodapruf's simplified LIGHTHERM Drymix Plaster method, which eliminates board handling, avoids upper-slab filling holes, and allows progressive inspection during placement.
