Okay, so I'm a little fearful reading this thread. I've a fantastic home that is paneled in addition to the rafters, which are 4x8, and I put in sloped cans and was gonna insulate and complete ceilings. My Principal reason of undertaking That is that the roof is instantly within the beams and it will get really scorching in the summertime, winter not much of problem as I reside in San Diego and temps not often dip underneath freezing.
I have previously insulated the steep sides of my unvented mansard roof with six" fiberglass (And that i had it inspected), do you advise I rip that out and use spray or board foam? I have gotten conflicting information on no matter whether to take care of it to be a wall or a roof.
I am a homeowner in Seattle. Possess a freshly-framed, vented cathedral ceiling to insulate. Straight bays, 2x12, 24" o/c. The current plan is to use batts of some kind inside the bays, get care to air seal the inside area, stay clear of penetrations, air seal the vent channel too (bays fully sealed), double prime The within surface for vapor resistance. I've a few questions about baffling the vent channel: one. A lot of the building experts I am Doing the job with come to feel the jury continues to be out on baffles and they are recommending leaving the batts open to the channel other than near the vents, assuming the 1-two" air channel is usually maintained.

You don't explain regardless of whether This is certainly new construction or the renovation of an present constructing. I relatively suspect It's a renovation -- or else a person may possibly Assume that the designer with the creating would even have provided a design for the roof.
My perception is that if we have been worried about air leakage compromising the insulation's efficiency, vent channels are problematic.
So the problem is: seal the stucco vents and add the spray foam roof and Don't fret about condensation? You can find really little very low-hanging fruit in our sort of design, Primarily on current residences, Which is the reason individuals are being sucked in the spray foam roof rip-off.
