Review: Good floor insulation - These insulation boards were just the right size to fit in my kitchen with minimal cutting required. Besides that the floor is now warm enough to walk on without shoes. You have to be careful not to crush it with chair legs etc but so far it's working fine for me.
Review: Used this to line my pond's walls. - I used this to line the walls of the pond that I have constructed over the present virus period. The item was easy to use and cut and did an excellent job of covering the rougher surfaces of the wall that I had constructed prior to placing the underlay (pond liner) down. It did an excellent job and I was pleased with the results. Would recommend for people who are willing to think outside the box for solutions that they may find in projects that they have.

## Questions & Answers

**Q: Can it be used as insulation for walls**
A: I used the product for my walls as we have an older property we don’t have the option for an alternative wall insulation. I applied using coving adhesive directly onto my walls they have made a HUGE difference... what was once a cold and sim room is now the warmest room in the house... we don’t even need the heating on in December. I want to wrap all my walls now....And say goodbye to my huge heating bills.

**Q: Can they used for keeping interor wall cooler in summer,ie reduce thermal radition from outer wall warming up interior say bedroom.?**
A: They are insulation boards. They are blue. They are easily dented if not protected from knocks.

**Q: My house and floor are freezing in the winter, would these boards under my laminate help much with this issue**
A: We laid in a staggered formation on floorboards in hallway and then placed laminate on top. We also added skirting boards after,  which kept everything in place. However butting up to existing floorboards should work.
We also laid on top of tiled floor in conservatory and laid laminate which has helped keep it warmer under foot.

**Q: Could I use these (cut to size and wedged) between roof beams in a currently uninsulated garage as a cheaper alternative to Kingspan?**
A: Hi, this is exactly what I have used it for. I have clad my shed in the foam to insulate against the wet and the heat. It is easy to cut and fit. Cheers

### ⭐⭐⭐⭐⭐ Good floor insulation
*by D***D on 7 November 2023*

### ⭐⭐⭐⭐⭐ Used this to line my pond's walls.
*by A***B on 16 November 2020*

I used this to line the walls of the pond that I have constructed over the present virus period. The item was easy to use and cut and did an excellent job of covering the rougher surfaces of the wall that I had constructed prior to placing the underlay (pond liner) down.

### ⭐⭐⭐⭐ Arrived damaged
*by P***N on 23 January 2025*

Arrived with damaged packaging to one edge, funnily enough, it's on a protected side, not the unprotected ends, I'd suggest better protection for transit, oh, and it was delivered to No.15, not number 11! Apart from that, it looks perfect for the job in hand, which is to insulate the walls in a built in wardrobe, to stop condensation mould. I can get around the slight damage when cutting to fit, which I'm sure I'll have to. The sheets are larger than I expected, even though it does give dimensions, so will cover areas pretty quickly. The blue will stand out a bit in the wardrobe, so I may paint it in the future. I've treated the walls twice, I'm waiting for the mould block paint, coming tomorrow, then the glue on Tuesday, I'll report back once the job is done. It looks good value for money, it's thicker than foil, should insulate better, should save on heating, protect clothes and cut easily. Update It cuts really easy with a craft knife and straight edge. It's stuck really well with a water based adhesive, fits really flat to the wall. So I can't really fault this product. Warning, make sure that you buy enough, I'm a sheet short I think, although I may be able to patch an inconspicuous part with the odds and sods of offcuts, which unfortunately there's not a lot of, as you can only order a minimum of 10 sheets!
