So we bought a house last month, it's an old 1930's built art deco style house with solid walls so we are finding in one of the bedrooms the exterior wall is prone to having condensation on it. The previous owners had painted some latex'y paint on some lining paper which was just holding the water causing small damp spots and meant there was a constant smell of wall paper paste.
I think its only bad as its the only exterior wall in the room and considerably colder than the others. So I spent last Sunday stripping the paper, the paint on the top was horrific and made the job 50 times harder than it should have been. I've left it this week with a window open and there are no signs the plaster is damp so now i'm looking to tidy the wall up and insulate it to hopefully stop the issue. As its the box bedroom I think the other half has plans for it to become a nursery so want to make sure it's done right.
I've been told before I put anything on top to PVA the plaster (or to use a Ronseal Damp Seal) to help but skeptical as to whether its needed.
I've seen 2mm and 4mm thick polystyrene backed wallpaper which is meant to be reasonably good but I'm a little unsure as can't see how it'll do anything - http://www.wallpaperdirect.com/products/wallrock/insulating-lining-graphite-4mm/97025
Don't really want to stud the wall out as the room is only about 8x8
Any other ideas/things I should do or use ?

Hadn't thought of that Gary. Seems to be quite expensive though ? http://www.condell-ltd.com/ProductDetails.aspx?ProductID=3905&gclid=CMf__d2TqcoCFcgYGwodMRMF6Q
Whilst I was looking I found this which has good reviews and is significantly cheaper -

Have you had experience with the Kingspan stuff ? Is it worth just taking the hit and going for it ? With the jablite stuff I'd almost be tempted to do our guest bedroom aswell as its so cheap.

I've worked in houses that were don't with that stuff and they were incredibly warm. If i were to do up a house I'd use it.
