Waiting to see results.
Bought to insulate a cold utility & hopefully prevent condensation. Put wood panelling over and then painted. Hopefully the coming winter will be better.

Good value insulation
Used to insulate the back of some wardrobes. Easy to use although found cutting with scissors' better than using a knife. Good value for money

Why not 10mm to go with the timber, also bought.
I have not yet used the boards as the projects in progest. Question for B&Q? Why did I have to visit four stoes whom all claimedf to have the product and correct amount in stock but could not find it when I mvisited them. A real run around, rubbish stock control.

Easy to use and fix
Quick and easy to use; l used PVA applied with a gloss roller to both wall and sheets. So easy and quick to do. Because the sheets are only 3mm, care must be taken when handling.

Standard insulation, good consistency
Good insulation in tight spaces, nice and cheap but does a decent job. Easy to cut, consistent grain and easy to stick on.

No. Information on what adhesive for use
EI found polystyrene covering adhesive did the job to stick it to the wall ,it says it’s suitable for wallpapering but despite a very helpful member of staff going on line no information could be found on what adhesive to use I tried extra strong wallpaper adhesive, primed with PVA and used the same adhesive,then tried PVA all failed still none the wiser
