Hi all,
we're in the process of purchasing a new house at the moment, but the roof felt has been exhibiting quite alot of condensation. I'd noticed this when viewing the house, but as all the visible timbers and panelling seemed dry and in good condition, didn't give it much thought.
The survey picked it up, though, and is suggesting "further investigation" with a view to increased ventilation.
At the same time, though, the roof joists have been insulated with 100mm of fibreglass and then boarded, the roof has a skylight in it, and shelving has been put all around, making the roofspace a very handy storage space.
I'm wondering if there's any reason why I shouldn't insulate the underside of the roof (between the rafters) to:
a) reduce the temperature gradient, and thereby reduce condensation
b) avoid having to bury the nice useful boarding under piles more insulation to bring it up to standard.
Everywhere I look, I see "cold roof" (ceiling level insulation) and "warm roof"(rafter level insulation) solutions discussed, but is there any middle ground where the loft is insulated at both levels to provide a "buffer zone" temperature-wise, whilst retaining maximum usability?
Thanks in advance for any thoughts.
