7mm Gold High Density Foam Acoustic DPM Underlay – 7.5m² Roll

The 7mm Gold High Density Foam Acoustic DPM Underlay is a premium all-in-one solution for noise reduction, thermal insulation, and moisture protection. Designed for use under laminate and engineered wood flooring, it combines dense foam with a gold foil vapour barrier to deliver superior performance across the board. Each roll measures 1m x 7.5m, covering 7.5m².

With an impressive acoustic reduction of up to 37dB, this underlay is ideal for flats, upstairs rooms, and busy households where impact sound needs to be controlled. The high density of 110kg/m³ provides excellent support underfoot, helping to stabilise the floor while reducing sound transmission between levels. The built-in DPM (Damp Proof Membrane) layer helps protect against rising moisture — making it particularly useful when laying wood or laminate flooring over concrete subfloors.

The 7mm thickness also adds a layer of thermal insulation, helping to retain warmth and improve overall comfort underfoot. Quick and easy to roll out and cut, this underlay is a smart upgrade that enhances the performance of your floor while extending its lifespan.

Whether you're installing new flooring in a living space, bedroom or apartment, this gold acoustic underlay provides reliable, high-spec protection in a single, easy-to-use roll.
