Insulated wallpaper any experiences?

[Grouperandoctopus]

I’m keen for any insulation at all, I think walls are single skin. Cannot currently afford to do anything external.
The room is too small to lose space to eg kingspan, so I was considering thermal wallpaper on the external wall.
Any experiences of hanging it and whether ut made any difference? It will be a pretty small area, so expense isn’t too much of an issue. I mean unless it’s a million pounds per sq ft.
Thanks for any opinions.

Bumping this in hope :)

I'm hoping someone replies too! Following with interest!

I’m sorry I don’t have any experience with insulated wallpaper but I would be surprised if it made any difference. If it even has an R value, you could compare it to other insulation to get an idea.

Have you considered getting the wall overboarded with insulated plasterboard? It will probably make a noticeable difference and could be as little as 27mm. Materials would only cost a few hundred and it would most likely only take a day To board and skim it.

We have it in one or two rooms here (I'm stripping it off as we renovate because it's wrong for the type of wall we have).
It definitely makes the walls feel warmer when you touch them, but where I have taken it off it doesn't seem to make much difference to the temp of the room. But we have cavity walls.
The one thing that made a room feel a lot warmer was plasterboard backed with insulation, stood off the walls by wooden battens. You do lose a fair bit of space, but it makes a huge difference. We just used it on the outside walls.
Is this a garage or outbuilding? It's odd that it is single skin otherwise.

It might not be, it’s a 1960s house. The room is very small, almost every cm counts sort of small.
It’s difficult to know who to trust with the reviews. Apart from the ones that say it’s a total nightmare to put up. Those I believe.
Also many are several years old, so I’d hoped there would be a bit more info/opinion about.
Making the wall feel warmer might be enough tbh. It’s a south facing room.

@Grouperandoctopus we just had this stuff put up along the inside of our external wall. Builder promises it will help warmth:

Master bedroom PL4000 Thermal Laminate Insulated Plasterboard

We're also redoing the heating and windows, but fingers crossed this helps too

Hm. Could maybe consider the 27mm…

There's a product called aerogel which has amazing insulation benefits and can be used in very thin layers but it is expensive. Here is the aerogel backed plasterboard price list to give you an idea - as you can see, you could get 27mm or thinner including the plasterboard - worth investigating?

Consider that an insulated cavity wall has between 50mm and 100mm of insulation.

EWI uses foam boards of equivalent insulation.

What's this wallpaper stuff? 4mm thick?

Trivial.
