We prepare to transform to an improperly vented cathedral ceiling to an unvented just one. Sealing up the soffit vents is usually a no-brainer. What is the best way to manage the ridge vent? Thanks!
My property built in 63 below in Ohio includes a cathedral ceiling without ventilation. In truth there many cross-supports functioning perpendicular to the main joists and various framing aspects that may make this unfeasible. So I intend to make it a successful unvented roof. 50 percent of your roof has 2x8 joists and the opposite fifty percent has 2x12s. At the moment there is a membrane covering (rubber) that's labored very well for over 20 years but is displaying indications of deterioration and might need to have replacing quickly. Obtaining completed transforming on the inside and strolling within the roof I are aware that loads of the sheeting really should get replaced combined with the very little insulation that's there now. We've had condensation problems previously so I now you can find air infiltration and bridging problems.
Sure It really is loads of hassle. It seems like fewer difficulty the depth posted as example while in the web site higher than and works by using no foam... Which happens to be a "biggie" for me.

You wrote, "the rafters are still exposed," but I'm unsure Everything you suggest by that. Do you have got kraft-confronted batts between the rafters, With all the kraft experiencing continue to obvious?

A whole new standalone direct vent fuel stove goes in in the far conclusion in the area under the steel box. I figure if we use XPS board, it would have to be pulled back various inches from all over that place, but I did not Assume it could reduce me from applying XPS solely. Seems like Roxul is significantly less of a difficulty with regards to warmth/fireplace.
The system: Portion A: I stumbled on one" Dow rigid foam backed 5/8CDX for a similar selling price since the bare CDX, and I decide to double it up just like a SIP, installing The underside sheet foam aspect up and the subsequent sheet on best (staggered obviously) with the foam experiencing down, providing me two" of insulation between the plywood.
