Wall paper type thermal insulation

[Scarletpimpofnel]

Anyone tried anything like this? Any good?

I have an external wall behind a wardrobe that gets cold and thought this would keep it warmer.

I used it.
Without a heat source it still slowly cools to the wall behind it, leading to condensation and mould still.
It did work on the visible bits of the wall, but not behind furniture.

It’s 3mm and conspicuously lacking any thermal performance figures in the Amazon listing…. Can’t help but suspect it’d be a waste of money.

It does !

"remarkable thermal insulation properties"

I would be concerned that putting an impermeable layer on a cold wall will be a recipe for damp.

I've used wall rock thermal liner a couple of times, I've currently got some in our bedroom behind a wardrobe on an exposed wall which used to get cold and attract condensation. The wall with it on is noticeably warmer to the touch than the wall directly next to it.

Very good point thank you.

Yes the impermeable layer is a problem waiting to happen I agree, thanks for pointing it out.

I was originally looking at white cork tiles, but with the correct adhersive that works out at about £100/square metre. The stuff you recommend is similarly expensive.

I was hoping for something half that price or less! I might just have to bite the bullet though and pay what I don't want to!

Very happy customer of Wallrock KV600 thermal stuff - yes, it is not cheap, but man it made a huge difference behind the bed. Extra bonus of being really tough to help the crumbling lath and plaster.

Yeah I've looking at that. The adhesive is expensive! I assume standard wall paper paste won't do the job?

The adhesive is pricey agreed! - it is really thick and gloopy, not like wallpaper paste, more akin to a resin version of PVA. - it does roll onto the wall nicely, it allows you to adjust the thermal paper nicely to line things up - worked very well.

Note, I just checked, I installed it in 2016... where does time go?! - You can order small sample pieces, or if you are NE Scotland I have half a roll left over.

Thanks for your time in replying. A couple of further questions:

1 - My house is old, the plaster is ok but does this adhesive bond so well that my old plaster will come off if I ever want to remove it?

2 - The spec for Wallrock thermal stuff says it "must be wallpapered" after setting. Why is that? I was assuming I could just leave it as is? Does the additional wall paper layer seal the fibres in the wallrock thus creating air filled pockets? (I'm putting it on a ceiling in a built in wardrobe so don't care about aesthetics.

No worries!

My flat had crumbling lath and plaster walls - I am guessing that if I ever come to take it off I would simply grab and pull - and expect all the plaster to land on the floor in a pile of dust. I would then clean up and stick on some insulated plasterboard - I very much doubt I would get the thermal paper to come off the plaster. (Also being rented, time would be a larger thought, so get a tradie in, get it cleaned, plaster fixed, skim the joints, and allow tennant back in ASAP - if it was my own house then I could possibly spend more time trying to patch things.)

I did go for their wallpaper ontop of the insulated stuff, the place where it is can be rubbed against with shoulders etc, and the insulation left a slightly rough and soft finish. Add on the fact that the walls were not the best condition to start with so not the most even. For purely insulative properties and not worried about abrasion / looks, I would not bother with papering it.

I had ordered a few sample patches, unsure if they still do those, but it was good to feel the stuff before spending a fortune on it. I decided against the polystyrene ball type insulation as that one was much stronger, unsure of U values.
