My barn again
Could we paint 4 coats of bitumen on the walls of the barn, before putting insulation in (& then either a stud wall or a block wall) to act as a bit of damp-proofing?
How much of a gap can we leave to put cavity wall insulation in?
Is there any benefit in putting an extra thickness of insulation?
Will this cause problems when fitting the windows if the cavity is extra wide?
Thanks
