A self-levelling acoustic underlay with a built-in DPM, Cushion Ultra Silver Underlay is made from 3mm thick high-density foam with a vapour barrier to keep moisture at bay. Suitable for DIY use with all click-together wood and laminate flooring, the underlay reduces impact sound by up to 19dB and can help to eliminate minor subfloor irregularities. 
 
The underlay is ready for use with underfloor heating and can be used in conjunction with Lumberjack M.B Primer. Seams should be taped and each 1m wide roll covers approximately 15m2.
