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.

Regards Sean


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.
