Thanks for the replies!
If i used the polysyrene method then I can paper over the top?
Would having cavity wall insualtion fitted be ok?
The gable is a double brick wall with a 30ish mm gap in between the courses.
Cheers
Bugger, thought you might say that. So its all back to brick again?
What insulation would be best to use?
Would cavity wall insulation help in any way?
Im quite a novice to building so all your info is greatly recieved.
EDIT:
Just found this...
After finishing the renovation of my end terrace, strange spots have appeared along the gable wall about 3 foot from the floor.
The spots have appeared where the plasterboard has been dabbed to the wall.
I need them gone now but I firstly need to know what is causing them and what I can do...
