Hi,
I have read lots of threads and the recent advice posting on this subject but I am not sure they have answered my problem.
Our loft has been recently converted. We have continuous vapour barriers in the ceiling and walls on the warm side. I cannot see any damage or holes. We have 300mm of insulation throughout. We have a mechanical heat recovery ventilation. The loft hatch is sealed and insulated.
There remains a small vaulted loft space and the roofing felt now has what looks like beads of condensation that are dripping onto the insulation in several areas, but not everywhere.
I am pretty sure it is not a roof leak.
I would really be grateful for advice on how the water vapour is getting into the loft given the vapour barrier and what can I do about it?
Cheers!
