SELITPRO 2.2 mm AquaStop

The best underlay in terms of acoustics & compression strength!

With its unique TwinFoam TM technology, the innovative SELITPRO® 2.2 mm AquaStop installation underlay for parquet- and laminate floors combines ideal noise insulation in the footfall and impact range with reliable protection of the floor covering from loads, normal usage, and falling objects.

The AquaStopTM+ surface also delivers optimum protection against rising damp with an sd-value ≥ 200 m.
