Questions & Answers


Is this product suitable for use with underfloor heating please?


Hi Susan,

Yes, this product is suitable to be used with underfloor heating. However, if you are screeding your floor, we recommend using ‘Underfloor Foil Insulation SFUF by SuperFOIL’ as it has a Polythene layer to protect it.

We hope this helps.
