We recently moved into a new house and to get some more storage space I have moved the secondary layer of insulation from over the top of the joists to between the rafters.
I am now concerned that I should have left a gap between the insulation and the felt. Do I need to take it down and redo it?
The house is a 1930s semi. The felt looks to have a transparent plastic backing I assume to prevent water ingress. There are no vents at the top of the roof, but there are a row about 1.5 ft from where the roof meets the joists (eaves?). The insulation is plastic wrapped glass fibre I think. Orange on one side and silver on the other.
Can anyone help? I have seen corrugated "baffles" which can be installed between the roof and the insulation, but these seem to be mostly on American videos and sites so I don't know if they are available. I'll try to add some photos.
