## Questions & Answers

**Q: Sfufs outermost surfaces are polythene and foam, so its thermal value is from its core value only what's that mean in plain language please**
A: The efficiency of the foil is the filler material sandwiched between these out skins. The surface materials have small thermal value themselves but keep the foil compacted together more than anything else I'd guess!

**Q: Is it specific for "underfloor"? Can I use it for loft insulation? What R value it will be?**
A: SuperFOIL SFUF is created for Underfloor use, and built to sit under screed directly among other things. Sometimes we have recommended this product to be used for other uses when space is tight. If you are desperate for the space this will provide some insulation, however it would certainly not perform as well as, for example, SF19+, SF40, or SF60 when all installed correctly, as those are designed for this purpose.

**Q: Is this safe to use with electric heating Matson it's own or say 6mm xps or equivalent boards underneath**
A: To late now for the op who hopefully house hasn’t burnt down but this is not to be used with electric ufh as it melts

**Q: Doesn't foil insulation need space around it to work effectively, if so how can this work under Carpets?**
A: Most multifoil insulation products have a reflective outer surface which boosts the thermal value of a sealed airspace, SFUFs outermost surfaces are polythene and foam, so its thermal value is from its core value only.

I used this product under my downstairs floors, stop the drafts and rebounds the heat from our central heating system.

*by M***  on Reviewed in the United Kingdom on 12 August 2021*

Cold concrete floorsTook Carpets up took skirting boards off, laid sfuf lapped up walls, taped joins and edges, refitted skirting and then laid carpet grippers,Refitted carpets,No noise(was worried about foil crunchy noise)It just feels like a thicker underlay, but I think if you have a longer pile you won't even notice it's there.Job done warmer room!If you cannot fit Kingspan etc due to lack of room this is a good place to start,It's definitely made the room retain heat more and hopefully in winter will cut down our bills,With gas prices continuing to rise it's a must to insulate where ever you can, this should pay for itself within the year.Update December 2021:the room temperature is definitely higher it's definitely working, ,only grumble is you can feel the joins under the carpet and underlay, but we do have a flat carpet, I'd say if it was a longer pile maybe you wouldn't,Thinking about trying laminate flooring over it and see if that's better, spoken to manufacturer and they're advice is it's fine for laminate flooring.But it's definitely working with heat retention,Definitely Recommended
