This acoustic floating flooring underlayment is designed for use with laminate flooring, floating engineered wood, floating bamboo, floating rigid PVC core vinyl planks, and wood/plastic composite (WPC 5mm or thicker) floors. This laminate flooring underlayment is even approved to use with in-floor heating systems, as it allows heat to permeate evenly while helping to protect the floor covering material from thermal shock. This interlocking floor mat underlayment helps to absorb and dampen sounds. The floating floor underlayment prevents sound from travelling to other rooms, making click-together floating floors sound solid underfoot. This convenient sound-muffling floor underlayment also wicks moisture away from your flooring and subfloor. The moisture-wicking underlayment uses DriWick technology to wick away harmful moisture from the subfloor while the attached vapor barrier protects the overlying flooring from moisture.
