Any advice would be greatly appreciated.
I have spent quite some time googling but can't seem to find a straight answer.
I have a fairly unusual house construction that has what I've been told is an early cavity wall with snapped headers to look like a solid "Flemish bond" also the leafs of brick are tied together by bricks bridging the cavities rather than metal wall ties. The bricks are soft reds with lime mortar and the internal plaster is lime. The cavity is approx 70mm & the bricks 110mm to each leaf.
Some areas need re plastering and I wondered if there are any options for insulating.
From the research I have done any solid wall needs lime plaster to be breathable but is that the case for the type of cavity wall I have?
Is it ok to insulate or plaster with non breathable materials since it has a cavity.
Thanks
