The 15m² roll is ideal for rooms of all sizes and makes installation straightforward — simply unroll, cut to fit, and lay your laminate on top.

This premium acoustic underlay features a reflective gold foil moisture membrane on the upper surface, acting as a vapour barrier to prevent moisture from subfloor concrete penetrating your new floor.
