No issues with product but would have been helpful to have measurements for this on ordering as it was not clear on area coverage per roll, had to buy extra elsewhere.

Can I use this on quarry tiles to fit vinyl click tiles?

Hi, The only underlay we suggest with click vinyl would be the prolay. Here is a link.

Can I use this underlay for underfloor heating? I have waterpipe heating running through both a concrete floor and floorboards?


The only underlays we supply for under floor heating is the heat therm plus for concrete subfloors


And for wooden subfloors you can use the normal heat therm

We live in a new build property currently with carpet would we need to screed before laying the laminate if we used this product?


a screed may not always be required, it depends on the subfloor. The subfloor should be as smooth as possible, clean dry and flat before installing the laminate on top. Please see the installation guide on the product page for more information. The underlay supreme with moisture barrier is fine to use with concrete subfloors.

I plan to use this underlay for engineered wood in my hall and dining room but have a small (2 sq mtrs) cloakroom off the hall where I want to use click vinyl tiles. Is this product suitable as an underlay for click vinyl tiles for this small area (on concrete)?

No, this is not possible as they are two completely different products and have different underlays, with click vinyl you require a very dense underlay for stability.
Please see our Prolay products which have been designed for this type of flooring.
