insulating old plaster and lath exterior wall

Insulating old plaster and lath exterior wall windows#

built with lime not cement) were built to different concepts compared to modern houses, and modern solutions often do not mix with the old. If you are going to treat your old house as it deserves, you MUST please take the long term view it's been there for over 100 years and it can do another 100 or 200 if you treat it right. Too often they will do their modern solution and not be around in 5 or 10 years time when things go wrong. Please do not let the fact that he has been employed as a builder for 30 years persuade you that he knows everything!IMHO, the vast majority of modern builders have absolutely no concept of lime mortar or breathability of old buildings, and will say things like 'you don't believe that, do you?' and 'a bit of cement will fix it' etc. However, the statement above leapt out at me and I think it's worthy of an urgent separate reply.

I'll do a fuller reply to your post a bit later, when I have digested it. I will add pictures when i work out how toĬlick to expand.Hi A.jones, welcome to the forum. Obviously he is the builder so knows more than me, he is the go to guy in this area and has been for over 30 years and said hes never had a problem I asked him if we could dot and dab the boards directly onto the stone so the walls could still breathe behind the boards ? Would that work? he said that would cause bad damp issues but i cant see how as the walls are bone dry and surely its better than cement plaster? I like the idea of insulating plasterboards but not keen on the cement plaster I didnt know anything about lime/cement until i started reading up about it. Now then, my builder who has been my landlord for the last 11 years wanted me to take the walls back to stone so he can then cement plaster and dot and dab on insulated plasterboards. Couple stud walls and roof insulation are being done this week.

So we are back to a shell !įloor insulation and under floor heating have been fitted, double glazed windows fitted throughout. It was all original with lathe and plaster ceilings and lime rendered walls, however the ceilings were sagging in a couple places after a previous water leak so we decided to pull them all down, then went onto remove all plaster off the walls and dug up the soil/stone floor. I recently managed to buy our first home which is an early 1900 stone house.
