Ask a question

Our experts will answer it

If i'm putting down 10mm of XPS sheeting on top of a screeded floor and then my electric foil matt underfloor heating, do I need, or would I gain anything but adding this underlay on top of the electric underfloor under the laminate floor or would it not be required?

The main reason is that it allows the flow of heat to be more controlled and we do not suggest having any underfloor heating in direct contact with the floor.

Yes this underlay is suitable to use over under floor heating.
