Grandismo® Underfloor Heating Underlay/Underlayment for Vinyl - Wood - Laminate Flooring/Floors

great quality! It covers uneven surfaces perfectly and provides a soft, balanced floor.

Worked great under my vinyl floor easy to fit ands tape together

Tried to find this product in every DIY shop where I live and none of them had it. And I couldn't lay laminate flooring straight on top of underfloor heating. This was perfect for the job and reasonably priced too

Very easy to use and simply does what it’s supposed to.

I covered the whole extension with this to go under my wooden floor and on top of floor heating. It's ok. I don't actually know what it does in terms of thermal flow. In terms of softness, it's fine. It is a bit easy to rip, and it stretches a bit as you roll it out. If not careful as you lay the floor on top of it it will move and stretch. But overall, happy with it.

Absolute must for electric heated foil matting when using wooden of LVT laminate.Can be a bit 'fiddly' when initially rolled out, but settles flat over time.Would be really useful to have printed cut guidelines to help cutting straight at the 'punched' holes are not square to roll!

I am a flooring installer, this underlay is designed to allow heat to permeate equally without reducing heat loss.Easy to use does not move around during fitting.

Very happy with this. Nice and thick. Exactly the quality I wanted. Would buy again. 👍
