Cathedral ceiling insulation
A quick clarification needed to settle my mind, I am hoping I solved my condensation problem. I am redoing my leaking cathedral ceiling which had R30 Roxul, no vents and tongue and groove pine. I am in northern VT and as you can imagine I was getting condensation on the underside of my roof deck.
I removed my tongue and groove (easier than expected), pulled the insulation down flush to the rafters and vented behind my Roxul (2×12’s so I had room). I then added 2″ of felt faced Polyiso flush across my rafters, taped and foamed for a tight air seal. Next put up new strapping and reinstalled the tongue and groove. Soffit and ridge vent installed.
Should I be all set with this fix?
