DAMTEC® system
Premium insulating padding for concrete or wooden subfloors
DAMTEC® system is the premium insulating padding for concrete or wooden subfloors. It provides outstanding impact sound deadening properties under screed or rigid floor elements. DAMTEC® system is characterized by a very low dynamic stiffness. Its special design and granular-textured surface ensure superior acoustic insulation especially in the low frequency range, the most difficult part of impact sound insulation. DAMTEC® system is ideal for use on wooden subfloors in combination with flooring of various types, generating high market demand particularly in the refurbishment sector.
