Q. "For an unvented design with no insulation above the sheathing, how about using wood fibreboard between the rafters directly underneath and in contact with the sheathing?"

I've developed dense-packed unventilated roof assemblies many moments without dilemma. Obviously I haven't torn into them possibly. I wish to see far more samples of failures in these kinds of assemblies if they're in existence.

Don't make any hasty choices that you'll regret. If needed, notify your roofer to stop all Focus on this venture right until this concern is resolved (assuming, needless to say, that your roof sheathing is protected by asphalt felt or an analogous underlayment.)

Many thanks for your personal response Martin. Would you continue to be joyful to implement that unvented process for any renovation scenario in which There exists non-breathable membrane (eg bitumous 'felt') earlier mentioned strong board sheathing?

I do think that you should publish a sketch. I can not visualize what you are speaking about out of your description.

Q. "If I execute the unvented roof as designed and set 4 inches click here to read of polysio over the roof deck, can I then use open up-mobile foam among the rafters?"

Your assembly calls for about 5 inches of XPS, for a total R-price of only R-twenty five. That's not Substantially. For those who will all that difficulty to construct a sophisticated roof assembly, it is best to intention higher.

In accordance with segment R806.five of your 2012 IRC, “Unvented attic assemblies (spaces concerning the very best-Tale ceiling joists as well as roof rafters) and unvented enclosed rafter assemblies (Areas right here amongst ceilings that are used straight to the underside of roof framing members/rafters and also the structural roof sheathing at the top in the roof framing members/rafters) shall be permitted” as long as several conditions are fulfilled.

Hello Every person. I see I am a little late into the bash on this thread but I hope somebody can even now enable me. From my matter line you can see I've fairly the home. I am the house owner and discouraged with my leaky roof. I reside in WI and my roof More Info has asphalt shingles.

In some cases, these ventilation channels are set up earlier mentioned a layer or two of rigid foam. It’s also possible to purchase nailbase (a style of SIP with OSB on one side rather than two) that features built-in air flow channels amongst the OSB as well as the rigid foam; one particular manufacturer of those panels is Interesting-Vent from Hunter Panels.
