Hi,
I've purchased a 1915 house and look at insulation. I've already started to replace the loft insulation but I was wondering about spray foam insulation on the inside of the roof but not sure what needs to be done first.
I've attached a couple of pictures showing the make up of it, not sure if it needs a breathable membrane before the spray foam and whether it's better for me to do this or the insulation company.
Many thanks
Mark
