Cushion Acoustic Pro Underlay is 1m wide & comes in rolls of 15m 2. Our Simple to use acoustic underlay is perfect for use underneath any floating floor installation across all types of sub-floor. Our Cushion Acoustic Pro underlay is specialised for sound reduction as it is compressed into a high density foam which combats the sound transition to rooms below & also prevents drum sound bouncing back into the room. With an impressive 20d B sound rating it beats the market standard underlay, providing the added sound reduction that really makes a difference. Cushion Acoustic Pro underlay is also combined with a vapour barrier to help prevent any unwanted rising damp affecting the floor which means it can be used over concrete sub-floors. An underlay must be used when the floating method of installation is used as it supports the joints of the floor prolonging the life of your flooring.
