When you’re installing new flooring, underlay is often needed to offer stability, comfort and noise reduction. There are a number of things you need to consider before choosing the right type for your new floor. If you have underfloor heating for example, you need an underlay that can withstand high temperatures. The Heat Therm Plus Vapour underlay for underfloor heating is one of the best quality underlays designed specifically for use with underfloor heating systems and features a low tog rating of .304.

Made from Poly-Foam it’s guaranteed to last the life of your floor. It’s designed to be used with stone or concrete subfloors and each roll will cover up to 10m2. It measures 1000mm wide, 10m long and 2mm thick, the vapour barrier we recommend to be fitted down to the floor.

If you need any further information on this or any of our other underlay products, call our expert team today. We offer a 14-day money back guarantee and typically deliver within 48 hours.

Can you use this with vinyl click flooring?


No, we only recommend the prolay to use with click vinyl. You can use the prolay with underfloor heating too.

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.

Answered 5 years ago

Is this suitable for use on top of electric under floor heating mat for an engineered wood floor?


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

Bought this because on underfloor heating, some issues: one pack was no one solid piece so had to patch. Also the plastic overhang on one edge was no existent on one roll so had to use tape to ensure no vapour breach.
