Barrier Plus Underlay

Barrier plus underlay combines all the great features of our barrier underlay, along with a sealing strip to make installation simple. Sold in a 1m wide x 15m long roll. The underlay measures a generous 3mm thick for good noise insulation properties.

As DPM underlays must be sealed together with a waterproof joint, this integrated sealing strip makes for a much more rapid installation and gives you peace of mind knowing that your moisture barrier is properly jointed.
