I have a stone built Victorian house which has had substantial alteration on the ground floor elevation. It is not viable to repair the existing stonework so, rather than render the stone wall, I thought it would look nicer with a skin of red bricks to match the existing Victorian wirecut bricks around the upper floor windows.
I would like to install insulation between the existing stone wall and the new brick skin, effectively creating a cavity wall on the ground floor.
Has anyone done something similar and, if so, what were the issues?
Do I need breathable insulation?
Do I need cavity trays and weepholes in the brickwork?
Does the brick wall need to be constructed in lime mortar to allow the stone wall and cavity to breathe?
How deep a foundation would you suggest for the brick skin which is only supporting its own weight and tied to the stone wall?
Thank you in advance.
