Selitbloc 1.5 mm GripTec is the ideal insulating underlay for modern vinyl and design floors. Its pressure-stable foam core provides reliable protection for the floor covering against damage. In addition, the innovative GripTec surface prevents the individual floorboards from slipping. Thanks to the exceptional noise insulation characteristics, particularly for impact noise, Selitbloc improves living comfort by creating pleasant room acoustics. Selitbloc is suitable for all floating vinyl and design floors with a minimum thickness of 4 mm. It can be used both in damp rooms as well as over underfloor heating systems.
