Thermopanel6mm Lite Single Sided Floor Tile Backer Board Insulation - Waterproof Insulated Thermal Barrier for Underfloor Heating (1250mm x 600mm) - Pack of 10

Our tiler recommended theses, we were going to use plywood so glad we didn’t. These are so much better for isolation and sound proofing and give a great surface for tiling. Highly recommend these boards

I used these thermopanels to add insulation to the main door of the house. Cutting and fitting was a breeze. Hopefully they will help reduce the amount of cooling the hallway receives from the thin wood panels on the door. They should also reduce the transmitted noise from out side.

Easy to use and install. Good layer of insulation prior to laying tiles.

I’m a DIY novice, but these panels solved the cold wall in my kitchen. Easy to cut and install. Saved me £200 -£300, as quoted by my builder.

a light weight, concrete solution for condensation!

The actual product is fine, just what we needed as a lining behind some shower panels, but the problem is really, as others have said, with the delivery.It just isn't adequately packaged to prevent damage to the corners and edges. Sticking 'Fragile' tape on the package will, quite honestly, make absolutely no difference to the way the package will be thrown around whilst in transit.It did have some plastic corner pieces, presumable to try and protect it, but they are woefully inadequate.Luckily, we were able to work around the damaged pieces but that's not going to be the case for everyone.It's a shame because the product is good, it's just let down by skimping on the packaging when they deliver it.It didn't look waterproof, it has to be said, but after pouring some water on a spare (broken) piece of panel the water just sat there and evaporated eventually. So, no worries there. Just beef up the packaging a bit, please.

Easy to handle, cuts no bother and installation takes no time.

Tiler refused to fit tiles to them as they were too flimsy to hold tiles.
