Your caveat is suitable and conservative. For your overwhelming majority of builders, however, the code requirements will retain roofs free of challenges.

Ken's depth (#ten) does an excellent career of chilly local climate safety. It's got what we are searhing for: Superior airsealing at the inside, fluffy things in the middle, and superior drying channels for h2o vapor at the very best. By changing from a small permeability sheeting to your high permeability membrane (at best) with venting previously mentioned, there isn't any more problem for roof rot although at the same time wind washing is prevented from the bays from the air & water restricted membrane with taped edges and seams. It seems to me for being a very durable assembly.

Q. "For an unvented building with no insulation over the sheathing, how about using Wooden fibreboard involving the rafters right underneath and involved with the sheathing?"

If you'd like to develop an unvented insulated roof assembly, you may have two decisions: (a) You may insert rigid foam to the exterior aspect within your roof sheathing, accompanied by a 2nd layer of roof sheathing and new roofing, or (b) It is possible to insulate the underside of the roof sheathing with spray polyurethane foam.

The plan: Component A: I came upon 1" Dow rigid foam backed five/8CDX for a similar cost as being the bare CDX, and I plan to double it up similar to a SIP, putting in the bottom sheet foam aspect up and the following sheet on major (staggered not surprisingly) with the foam facing down, giving me 2" of insulation among the plywood.

Indeed a cathedral ceiling depth will be quite similar though the challenge of numerous cathedral ceilings would be the included structural aspects, electrical containers, and the need for wood board ceilings all which start compromising the drywall layer which in your element is employed on the air barrier.

I think that you'll want to article a sketch. I am unable to visualize what you're talking about out of your description. In order to set up an HRV in your attic, How come you must install a waterproof stucco roof more than some sort of EPS box? Is not your attic previously dry? Most attics have roofs.

Set up a layer of closed-mobile spray foam in opposition Resources to the underside of your roof sheathing, and fill the rest of the rafter cavity with an air-permeable insulation. Again, this kind of assembly is designed to dry to the interior, And so the assembly really should by no means involve an interior polyethylene vapor barrier.

We experienced a Zip Roof installed and a metallic Roof placed about try these out it. The roof assembly is just not vented and taped all around the soffits. Ideally I might like to pack the complete cavity with blown cellulose. This string of discussions is giving me pause for considered.

Are you wondering the 'flat' vented cavities won't supply the assembly with an exhaust route for moisture?

We plan to transform to an improperly vented cathedral ceiling to an unvented a single. Sealing up the soffit vents is often a no-brainer. What is the best solution to deal with the ridge vent? index Thanks!

"Each and every household is unique. The elements that might have saved the roof sheathing of the home you explain could consist of:

I have crafted log homes while in the Yukon Territory in northern Canada for 30 yrs. Most log structures have cathedral ceilings. Most of the roofs We've got designed are as follows (from The underside up): log purloins, nominal two" (2x6) t&g decking, 6mil poly, 1 one/two" extruded polystyrene foam, 2x10 rafters on 24" facilities, seven" fiberglass, 2x4 strapping, 7/sixteen OSB, underlayment (fifteen lb paper, 30lb felt, or now we'd even use ice and h2o shield). There could well be about an inch of air space beneath the strapping for both equally vertical and horizontal air move. All roofs are vented with strip vents at the eaves and vents inside the soffit (2x6 t&g) at the height at both of those ends. I would disagree that venting is just not wanted should you end the airflow on The nice and cozy side, for 2 good reasons. First it is actually quite challenging to halt all airflow, Particularly with traditional regular procedures (ie chimney and plumbing vent penetrations through the roof) We've got a number of approaches formulated over the years to seal the vb within the eaves and gables, but there are still nail penetrations with the vb. In general I believe we experienced extremely limited seals but 1 could by no means say airtight.
