Hi,
Bought a house (victorian semi) with two loft/attic rooms. One was already converted, the other bare brick and pitched roof.
The rafters are about 70mm deep, with black bitumen-type felt which looks to be in fairly good condition. The previous owner had started putting in 80mm foil backed Kingspan between the rafters, and left me a few sheets.
So I've continued the job, used up the rest, with a view to building down the batons by a couple of centimetres and boarding the ceiling.
Started reading about it all, and it turns out I might need an air gap. At present there's no air gap at all. Just tiles on felt type stuff and then insulation filling the rafter gap.
Have pulled out a couple of the blocks of insulation, there's no sign of damp.
Do I rip it all out and start from scratch?
I need to do the other room at some point, the plan was to beef up the insulation in that one too. Not sure now, but I'm going to lose a lot of headroom if I have to insulate below the rafters.
