Hello, I have bought a house recently and I want to inprove the loft insulation. So far I've found all the information I need rgarding the loft floor insulation and boarding in the folum but I cant find anything regarding insulation attached to the roof itself. My property has had insulation, about 25mm deep, fitted under the roof slates in between the joists that run under the slates. Is this ok? and if so can I include that as part of my total loft insulation when trying to make up the 270mm?
There is still room between the surface of this insulation and the bottom of the joists (about 25mm). If I fitted plaster board to the joists would this be enough for a ventilation gap if I kept it all round?
thanks
