Have you used it? the toolstation blurb seems a bit odd using bricks and concrete as a comparison rather than other insulation products. And the reviews aren't available at the moment. But thanks for taking the time

I think they use those materials as a comparison as they have terrible insulation properties!

I read this a while ago, it has some figures and may be interesting.

“Are better methods available?
There are much thinner methods of carrying out IWI using insulating paint, or Aerogel mixed with plaster (1 to 3mm thick). However, these have dramatically lower insulating performance (thermal resistance of 0.8 or 0.9 m2K/W, or around a tenth of the improvement of 60mm of polyurethane). There are also insulating wallpapers like Sempatap (10mm thick), but this also has much lower insulating performance (thermal resistance of 0.98 m2K/W, or about a fifth as good as PUR). The thin insulation methods are cheaper and easier to install than conventional methods, but neither interviewees nor literature sources advocated them.”

I'm not saying if its good or bad. Something is better than nothing. I have stripped acres of the polystyrene off the walls of my new (very old) house before decorating. I have a new found hatred of it.

Oh I'm sure compared with all other insulating methods, its by far the worst, but as you say better than nothing.

Yeah, and if you use orange insulation paint its even warmer.

Thanks for the tip

Put it on with a half inch brush the effort keeps you warmer for a while anyway ??
