A coupled underlay roll composed of a blend of granules and selected fibers in SBR rubber bound with polyurethane resins (MDI), continuously thermobonded to cross-linked polyethylene. The uniqueness of the material stems from its incorporation of the advantages of SBR rubber, such as elasticity and long-term durability, along with those of polyethylene, including ease of adhesive adherence and the waterproofing of SBR rubber.
As a result of the upper presence of polyethylene, the product does not require an additional layer of waterproofing before the screed is laid. Material joints can be easily sealed using dBred adhesive tapes.
Reduction of footstep noises on floors with a floating screed system or as a resilient layer under low-thickness floorings.
