Condensation control in newly built loft conversion
by Lee Ray
I have my new floor down and I am now cutting the insulation between the sloping ceiling joists (rafters) and have found my existing felt is saturated.
Although there are no leaks as such, i know once i have battened over the cut insulation with full boards of insulation, taped and masti sealed at the edges, i'm wondering will this be enough to stop any penetrating water or would it be advised to use a dpm or vapour barrier as well?
Don't want to have moisture problems later on..!
