Looking for insulation backed board to put between bed and cold external wall

[johnnybuoy]

My daughters bed is up against a cold external wall so I was looking to but some sort of board with insulation at the back between her bed and the the wall.
It doesn't have to be very big ..say 2 feet by 3 feet by 1/2 inches thick.
I don't want to dryline the wall because that would take a couple of inches away from what is already a very small .
Any suggestions appreciated.

What about maybe using wood flooring underlay. Has the advantage of a damp proof membrane too. Not sure if it would work but is a lot thinner than board. We have half a roll spare in the garage if your in South Wales. Something like this

I should have said I want something solid that I can paint the same colour as the wall as it will be visible.

A rug might work well.

Wall rock thermal liner? It's like an insulating wallpaper between 3 & 4 mm deep that can be painted over. Not quite as effective as plasterboard with insulation bonded to it but you should get a warmer room without losing space?

B&Q sell insulation board in varying sizes. I can't remember if it has a plasterboard finish. You could make a feature pin board of it if it can't be painted.

I they the key would be the opposite, rather than trying to blen in make a contrast like a soft headboard (the are all kind of DIY tutorials) to be used for the length of the bed, it could double as a comfy seating during the day .

I like the rug idea too, and there are sum fun textures out there like this: www.ultimatehomeideas.com/wp-content/uploads/2014/09/Textured-rug-headboard-ideas-for-bedroom.jpg

a thin one will not be effective.

Consider that CWI is between 2 and 4 inches thick, and loft insulation is between 6 and 10. The products that are basically high-priced wallpaper are no good, they feel warm to your finger because you are touching a less conductive surface and you are feeling your finger warmth.

You could screw a rigid foam-backed insulating plasterboard to the wall if you wanted, but less than an inch of foam will not be worth the trouble.

Hi,
Did you ever solve this issue? I would be very interested in the solution you used as I have a similar issue.
