I am converting a single storey flat roof extension to a pitched (slanting from house) roof.
I plan to use celotex insulation between the joists and then screw plasterboards into the joists.
Is there such thing as hot/cold roofing systems with a pitched roof and with vaulted ceilings?
I have concerned myself because with the plasterboard screwed to the joists and the gap between joists filled with celotex, where will warm air escape to? Surely there needs to be a void?
I will be using the recently favoured membrane under the tiles rather than traditional felt. I understand this helps with ventilation to an extent.
