It provides a fantastic moisture barrier and makes the subfloor easier to install too.

Constructed from polythene, you could also use this underlay assist between screed and concrete. While it is primarily designed to prevent moisture from damaging the floor, it also offers additional comfort. When combined with a good quality underlay, your new wooden floor will feel incredibly comfortable underfoot.

The damp proof membrane polythene underlay assist comes in 20m2 packs. It measures 5000mm long, 4000mm wide and 1mm thick. Not sure whether you need it? Call us now and one of our staff will be happy to assist.
