Damp Proof Membrane Polythene Underlay Assist CWA11
While concrete subfloors are common, they do sometimes pose a moisture risk. If you’re fitting a wooden floor, the damp from the subfloor could potentially cause serious damage over time. That’s where the damp proof membrane polythene underlay assist comes in. This great product is designed to be used underneath the underlay. 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.

Bought this along with engineered wood flooring. Great communication, delivery to suit me (order held for at least 5 weeks for me), nice product at best price on internet......would give 5 star but only 4 so far as floor not fitted yet.

We plan to buy an oak engineered floor from you for our dining area and kitchen. It is 14mm thick from the manor collection. I need underlay. You advertise a budget underlay for £15.95 and a polyethylene DPM for £18. Do I need both - one on top of the other or will one of them do, in which case which one. Many thanks.
If you are installing onto a wooden subfloor then there is no need for a moisture barrier or DPM. The budget underlay is only suitable to use on wooden subfloors. If you are installing onto a concrete subfloor then underlays such as the underlay supreme with moisture barrier or the pro gold will be fine.

I would like to know if this would be suitable to use on top of a cement screed with a wet system underfloor heating. If so, wether I were to use another underlay as well under suitable laminate flooring?
The best underlay to use for this would be the heat therm plus - The DPM sheet is not designed for underfloor heating systems.
