I'm hoping we don’t must tear down all of the exterior wall drywall to re-insulate the house if an interior vapor barrier is required …. (Spray foam is not really a choice as a consequence of chemical sensitivities in the house) – and would appreciate any thoughts.
If it DID get put in at The situation revealed within the depth (at the best from the bracket) what was it meant to accomplish?
We however necessary to determine ways to mechanically fasten six inches of rock wool to the outside of the house. We wanted a procedure that will assist the vertical load in the insulation along with the siding as well as horizontal lateral masses exerted by wind forces.
The institution of The brand new Rockwool plant in a very coal Electrical power sourced location is disappointing: ideally they can strengthen their course of action to reduce their use.

When the Home windows are shut within our property, we don't listen to rain storms, superior winds, cars driving by, or coyotes howling through the street. It is really rather darn wonderful how mineral wool (and I'd guess DP cellulose in addition) can quiet the inside living Room. So for people living in a metropolis, on the hectic suburban street, within an apartment intricate, or inside a rural ecosystem like mine, mineral wool will always be our selection more than fiberglass.
The designer of a deep Electricity retrofit job in Massachusetts specified six inches of mineral wool insulation for the exterior side of your walls
You typically need a non-vapor permeable insulation exactly where there are actually moisture problems. Rigid foam is actually the best choice in this article. You do not mention what your certain problems are, but you will find 3 major types of rigid foam: EPS, XPS, and Polyiso. EPS and Polyiso are almost certainly the safest with regard to any outgassing, so perhaps a kind of would work for you?
I don't think the latex paint are going to be a problem in reasonable thicknesses. "Acceptable" listed here would be a quick spray used coating to act as a binder. I do not really Assume you'll have any issues with shedding though.
You would not want to do this over a roof, but I'd consider using some kind of air flow baffles, both internet site designed (1/2" polyiso works perfect for that), or a thing premade like Duravent.
Mineral wool Evidently has a lot of powerful Gains but with all that it's got, I am baffled why they conquer the drum of its acoustic Gains so tricky as though its special or so far better compared to the Level of competition.
Intumescent paints and sealants expand when heated, and are used for fire blocks. I would NOT use such a paint around the mineral wool. It is not essential for hearth proofing either, the mineral wool itself is currently basically fire evidence (which is employed for hearth stopping). There's no advantage to putting intumescent coatings on wires and pipes.
Even though we uncovered examples of identical click here installations in Europe, our constructing science consultants (Cathy Gates and Ken Neuhauser) were involved that wind-washing with the fewer-dense batts would degrade the thermal functionality of the insulation.
Rockwool can be a multi-countrywide foreign Company that places their manufacturing services in the poorest States Together with the the very least stringent pollution controls. Their latest plant in West Virginia is slated to burn off eighty+ plenty of coal and one.
