The shortage of tumble protection in image #six is somewhat alarming. OSHA has actually been building the rounds in Massachusetts even on compact assignments such as this.
Does “breathable property wrap” go in between the baffles as well as the Rockwool? As soon as which is comprehensive supplemental Rockwool are going to be placed on top in the detachable pieces of sheetrock. Does your “intelligent vapor retarder like Membrane” go above the sheetrock and down below the Rockwool? I never expect this to generally be a fairly easy procedure, but when it might operate I’m up for it. The first objective is to take care of the challenging-earned all-natural air circulation resulting from now-Functioning soffit vents and the re-founded ridge vent.
Additionally, there are Exclusive sheet products which may be used that functionality just like a rain monitor. Benjamin Obdyke is a great case in point:
With appropriate organizing, the set up on the assembly was systematic. As soon as all of the exterior finishes had been stripped down to the original sheathing, we transferred the wall stud locations to marks on the muse, taken out the roof eaves by using a chainsaw, after which you can wrapped the building shell in Tyvek like a large birthday current, meticulously taping seams and button caps, with careful attention to penetrations and drinking water management particulars at doorway and window openings.
Nevertheless, we preferred solution that was easier, more affordable, and would stay away from the need to notch the insulation boards around the fiberglass clips.
Concern one: Soffit baffles seem to be needed for spray-foam, blown-in and in some cases overly fluffy fiberglass batts. On the other hand, if we’re using rigid batts are soffit baffles even required? My only considered is they help have the cold air up and more than the ceiling, making a guided route with the air to movement. Problem two: Because the joists are 2×6 inches I wished to take care of a similar peak for crawling over the joists for visual inspection, repairs or modifications.
Insulation does not warm just about anything; it prevents heat transfer. Most builders choose rigid foam for interior basement insulation. Here are some posts that ought to be useful:
in just one local weather space. That’s because the ambient air in blended-humid climates has a tendency to have substantial amounts of dampness most of the yr. Additionally, considering the fact that air conditioning is put in for most new properties, chilly surfaces are present on which condensation can happen.
We very first considered employing rock wool batts, as they typically have the exact same thermal value for every inch since the denser board items, while getting cheaper plus much more readily available.
As an instance, Clark refers Wiscoguy into a bulletin from the Making America Alternative Heart. A “Grade one” installation signifies that the insulation, whatever variety, ought to fill wall cavities uniformly, filling Every bay aspect to side and major to base “without the need of substantial gaps or voids all around obstructions.”
RE seem attenuation, Johns Manville manufactures fiberglass and rock wool batts -- and states "...the real difference in acoustical general performance is so negligible that human beings would not have the ability to differentiate a distinction between The 2 supplies inside of a wall cavity." See: Be aware, however, that JM did not specify whether or not dense or regular fiberglass batts had been utilized During this comparison, and seem reduction is far more sophisticated than only which sort of batt you employ in the wall.

You Plainly know a LOT about this insulation/vapor barrier challenge, And that i Evidently know not a great deal. click here But I’ve now seemed into your polyiso reference, and Assume it might be dominated out for this unique challenge. The provider to the Rockwool insulation I am checking out tells me it does not are available in a “faced” Edition.
You don’t need a vapor barrier when insulating a ceiling concerning conditioned Area plus a vented attic. You from time to time need a vapor retarder (you always don’t want a vapor barrier) in certain forms of walls. I think what you have is something like the “Devil’s Triangle” region of Tale in addition to a 50 percent variety properties. If that’s the situation, you should protect the attic side of your wall insulation to forestall convection currents from cutting down your insulation’s efficiency. Occasionally house wrap is employed, but I choose to use polyiso. If you use polyiso exactly the same thickness as is needed within your local climate zone (more than likely R5), You then don’t need an interior facet vapor barrier.
