This text was quite instructive and appeared to provide a whole lot of advice on cathedral ceilings. But what what my perfect storm? Your home is thirty years previous (80's) and im positive the ceiling will not be air restricted. I choose to do anything this summer/drop to test to fix these leaks but I am fearful that whichever I do wont operate and can be a waste of cash, Particularly due to the fact I havent heard of a sound Resolution.
Code does not look to use as it's grandfathered in. It looks like I should redo the corridor ceiling.
My guidance will be to seal the existing vents. If insulation contractors inside your area are setting up 3 to four inches of closed-cell spray foam previously mentioned the roof sheathing, it's not necessary to get worried about condensation or dampness accumulation in the sheathing.
So a hybrid strategy really should be investigated. Dense packed cathedrals with warmside ridged foam to include R, taped, no recessed lighting or other air paths after which you can belt and suspenders... Include venting While there isn't any normal 1" vent path.
A. Either tactic will function, as long as you obtain at least the minimal code R-price on your roof, and as long as you employ building approaches that listen to airtightness.
Dan Reams, many thanks for your personal feedback. I also are now living in snow country near Yellowstone National Park. I normally have properly around 3 feet of snow on my cathedral roof. I feel the dew level is frequently from the snow rather then during the roof. The R value of the snow is frequently near the R worth of the roof. This may lead to significant ice dams. An easy thermal Investigation reveals that you cannot put a useful amount of insulation inside the roof to prevent the ice dams and transfer roofing company atlanta the dew position in the roof.
Initial, many thanks Martin for that prosperity of knowledge this website has. I've been checking out it regularly for the previous few decades, ever considering the fact that obtaining my to start with home. I'm also situated in northern VT, zone 6 but I do think we may be pushing seven resulting from localized ailments. I've recently had an Vitality audit carried out and desired to confirm one of several recommendations. We now have an area with a cathedral ceiling, and in addition a lose dormer designed into the cathedral. The cathedral ceiling is insulated with r38, plus the get rid of dormer with r19. Both are kraft confronted fiberglass. The roof is 12/12 over the cathedral, not sure but less within the dormer, and has snow coverage (often more than 8") from the start of January until finally mid March.
That seems really interesting: go with R-30 about the underside from the deck at our property using a mix of fiberglass batts and XPS as I described earlier mentioned, after which incorporate an extra R-10 (two" read XPS) on the top side once we tear down and re-roof? Unfortunately that feels like It is too effortless.
Could it be all right so as to add peel-and-stick membrane to choose areas on the roof and continue to keep The remainder breathable with tar paper?
In a phrase, no — the code explicitly forbids this technique. Cellulose can only be Employed in an unvented roof assembly if there is an suitable layer of rigid foam earlier mentioned the roof sheathing or an sufficient layer of shut-cell spray foam beneath the roof sheathing. Cellulose by itself received’t get the job done.
Next, can you please confirm this: "If you need to use only one type of insulation in unvented rafter bays, that you are restricted to spray polyurethane foam."
Insulated cathedral ceilings are a comparatively recent phenomenon. The trend for insulated cathedral ceilings (and excellent rooms) seriously took off from the seventies and nineteen eighties, when illustrations commenced popping up like mushrooms after a warm rain.
You might skip page the tape on the highest layer of plywood to exact some time and cash. That's likely what I might do if I were being you. That stated, there isn't a harm in taping the seams of the very best layer of plywood.
With this system , there isn't any challenges with an entire peel-adhere roof underlayment along with the deck is there? I've a steel roof on this undertaking along with the underlayment will likely be absolutely adhered towards the roof sheathing.
