Because of my silly oversight in booking the screeders at work I have a young and talented plasterer to find work for. I also have my solid wall to insulate. The plan is to rapidly remove the existing plaster and dot and dab 50mm celotex type insulation and 12mm plasterboard.
When this was previously discussed a plastic insert, like a frame fixing with a large head was mentioned and a foam rather than dot and dab adhesive, can anyone let me have some links?

Do you mean these:
not wishing to be a smartass, but AIUI if you strip off the old plaster (more than 25% of the area) you will tecnically have "interfered with a thermal unit". then you have to insulate it up to today's building regs which needs more than 50mm celotex.

and you'll make a huge mess to save an inch- why not glue onto the existing wall?
[g]
The house had a fire somewhen in the 40s and much of the sand cement has failed so the plaster has spalled in places. I expect they skimped on cement for the rebuild due to rationing.
Thanks all for all the links.
Robert what would be the depth of celotex on a 9" brick wall be to meet building regs?
AJH
IIRC, about 70mm.
only if you tell the BCO... ;-)
(in fact insulating alone probably becomes notifiable after a certain area is reached)
So they should be notified whether I strip plaster or not?
I may stretch to 60mm of insulation but it's already a small house and I'll do one room at a time.
One of the things about LA cutbacks is that the policing of planning and building regs has gone out the window.
AJH
Never does any harm to hang a dustsheet at the window to avoid prying eyes and don't have a skip outside if not notifying.
People occasionally get caught if a BCO happens to pass on the way to work and gets curious.
There;s a nice calculator on the celotex (or was it the Kingspan) website, but I remember it being 100mmm for the current wall U value requirement.
