SELITBLOC®-underlays have been specially development for the requirements of vinyl and design flooring. Their pressure-resistant foam protects thin flooring from damage at the click connection and prevents the floor from becoming uneven. They also reduce impact sound. The slip-resistant surface (GripTec) prevents the boards from shifting out of place. Blauer Engel and TÜV certification prove that SELITBLOC is THE underlay for vinyl and design flooring.
