I have recently increased the depth of my loft insulation and tacked insulation across my roof rafters, ( the thin silver stuff ). I now have moisture behind the roof insulation , not so much during this present cold snap, but a month ago. I have maintained the gap between insulation and eaves.
I have also maintained a flow from one soffit to the other, ( front to back ).
Tile vents have been suggested but because I have insulated right across the rafters doesnt this make a series of seperate voids or cells with one cell cut off from the next one?
One further question - what is the reason fro fitting a netting "hammock" under floor insulation?
I would be grateful for any help on any or all of these matters.
