If this have been my home, and Should the fiberglass batts are obvious, I'd pull all of the insulation out of a few rafter bays to find out what is actually up there.
Your strategy to set up 8 inches of rigid foam is a great a person, however , you might be able to put in thinner foam if there is a powerful explanation to take action. Obviously, 8 inches of rigid foam has an increased R-benefit, and can execute superior, than a thinner layer.
Ken's detail (#ten) does a superb career of cold local weather security. It has what we are searhing for: Great airsealing at the interior, fluffy things in the center, and very good drying channels for h2o vapor at the best. By transforming from the very low permeability sheeting to the large permeability membrane (at prime) with venting above, there isn't any additional worry for roof rot when concurrently wind washing is prevented from the bays from the air & h2o limited membrane with taped edges and seams. It seems to me to generally be an exceedingly resilient assembly.
First, many thanks Martin to the wealth of information this Site has. I have been viewing it regularly for the previous couple of years, at any time because acquiring my initially dwelling. I'm also situated in northern VT, zone six but I believe we could be pushing 7 as a result of localized circumstances. I have recently had an Strength audit carried out and desired to validate one of several recommendations. We have now an area that has a cathedral ceiling, as well as a get rid of dormer constructed in to the cathedral. The cathedral ceiling is insulated with r38, along with the lose dormer with r19. Both are kraft faced fiberglass. The roof is 12/twelve on the cathedral, undecided but considerably less on the dormer, and it has snow coverage (frequently over eight") from the start of January till mid March.
I feel that most contractors would be worried about the buildability of one's approach. The Picture demonstrates a small-slope roof in excess of a flat ceiling; this allows workers to stand on the ceiling joists.
You aren't the one particular person using this type of worry. For individuals who (such as you) are concerned about The difficulty, There are 2 options:
Am i able to get some much more commentary to the "total roof" of Ice & Drinking water Shield? I believe this experienced hardly any to accomplish While using the failure. The key reason why why I ask is I've a similar "whole roof" structure coming up, Even so, the rafter bays are all straight runs with soffit vents, continuous vent baffles (1/two" plywood) and constant ridge vent. Dense pack cellulose, two" XPS underneath 2x10's, air tight drywall (XPS may be sealed up much too).
It is absolutely not restricted to an R 80 Passive House roof. Take out the parallel chord trusses and slim it up.
Next, could you be sure to affirm this: "If you would like use only one kind of insulation in unvented rafter bays, you might be restricted to spray polyurethane foam."
You don't describe irrespective of whether this is new development or perhaps the renovation of the existing building. I rather suspect it is a renovation -- or else one particular could feel that the designer from the constructing would even have provided a design to your roof.
I'm with Martin on this one particular, your depth is labor intensive for tiny if any gain for my part. The vent channels we explain can be achieved following the roof is on with the underside (dry side). For anyone of us building in a cold climate this is a big advantage, we shell out as very little time as is required within the roof.
I've a partial cathedral ceiling from the finished attic of my dwelling in zone 4 (TN). Every single slope in the roof is split roughly in thirds by three various cases: knee walls at the outer thirds, "cathedral" ceiling in the center see page thirds, and a vented "attic" in the middle 3rd having a ridge vent - a standard circumstance with concluded attics, no less than about in this article. I have a major difficulty in the summertime with overheating. The insulation is just not Doing work perfectly as it was badly insulated with just R-19 fiberglass batts between the rafters without having a ventilation baffle or sufficient soffit venting and only r-19 blown in the "attic space". Additionally, my upstairs HVAC ducts are operate from the Full Article really sizzling "attic" Place underneath the ridge. Based on what i haved discovered from numerous content right here, my prepared Remedy is usually to cathedralize all the roof, eave to ridge: set up continous air-tight website-designed two" vent channels utilizing foil-confronted polyiso board (as instructed in ), installing ongoing soffit vents to considerably Enhance the airflow from soffit to ridge, generating an air-tight ceiling under the rafters, and, most importantly, carry the ductwork inside the conditioned envelope.
The approach: Element A: I found one" Dow rigid foam backed five/8CDX for the same price tag as the bare CDX, and I decide to double it up just like a SIP, installing the bottom sheet foam facet up and another sheet on top rated (staggered needless to say) Along with the foam experiencing down, supplying me two" of insulation involving the plywood.
