OK, possibly a slightly stupid question (My speciality!)
I'm in the middle of redoing my loft to give me a basic floor and stuff sufficient for model railway use, nothing fancy.
I've now been insulating right up to the eaves over the last couple of days, and I've discovered there is *no* air gap at all there. It's very difficult to get under there, but after digging out the original Victorian ash insulation, I haven't got any sort of air gap.
(FWIW, I can see daylight at the top of the roof where I join the terraces on either side. No leaks mind)
The roof was replaced sometime in the 80s, and has a plastic membrane under the tiles.
No current condensation problems that I've ever seen.
My intention is to add insulation under the roof as well as the floor to try and keep the temperatures a little more in check, but I'd appreciate any thoughts on the ventilation or lack of it?
