Hello
Looking for some opinions I am Building an extension at the moment and I was considering filling the space between Roof rafters with spray foam insulation before slabbing ceilings with insulated slab
I think the spray foam will fill roof cavity completely avoiding ventilation Problems etc
I cant fit insulation on outside of roof ie warm roof as I am tight for slope on roof
any advise welcome please
thx
