Cavity Wall Insulation - CELLAR

fluffymuffin

We are converting our cellar into a kitchen - its kind of a cellar anyway - our house is on a slope so the cellar is actaully the ground floor at the back. Only three of the walls are actually below ground level and as we are in a terrance none of them actually retain the earth at the other side. We are studding out the walls with plasterboard (fire regs proof of course) and setting this on a wooden frame.

I just wondered if anyone could provide any advice on if we should put insulation between the plasterboard and the walls (which are tanked to prevent any damp). We have had conflicting advice - some people say yes for insulation and some say no as if the wall does get damp it will provide a pathway for the damp to get into the plasteboard/studded wall.

Anyone got any impartial advice?

Hope this makes sense - its a bit complicated to explain without being able to draw a picture! Thanks for looking - any help appreciated xx

i think i can picture what you are proposing, but the bottom line is - if your basement has been tanked then you have no worries (at least if you have probs with damp your worries are more about the internal render so a bit of plasterboard damage is insignificant)

a lot of work goes into a proper tanking job to ensure there is no damp penetration so build your studs as per usual

Thanks for the advice will get on with the studs as planend.
