Then we get to the NRC rating. That rating is about absorption, so I see it generally within the context of acoustic control in lieu of sound attenuation/blocking. It really is, indeed, widespread to make use of mineral wool batts to build affordable acoustic Command panels.
Thanks for that reply. Your home quality is higher plenty of which the water desk is down below the footing and would even be below the sump. There’s a decent hill in my again garden sloping all the way down to the swampy spot. I’d say probably twenty ft elevation variance. That’s a very good question on The location of your insulation. I’ll take a look at that a lot more but creating a couple of assumptions. The way in which the insulation is normally installed is by taking pictures a nail and plastic procedure in the board and in the wall.
That may indicate 1” polyiso on the attic side with the studs, then mineral wool within the wall (I’m assuming 2x4 partitions here, When you have 2x6s you would like thicker foam to keep up the same ratio of batts to foam and also the ratio will be the essential aspect) and also you’re fantastic to go. Should you don’t choose to use rigid foam around the attic facet in the walls, then I’d tack up some breathable housewrap (don’t use poly in this article!), then batts, And that i’d use a wise vapor retarder like MemBrain on the interior under the drywall. If this doesn’t sound like Whatever you’re wanting to do, article a drawing exhibiting wherever you want to insulate to help you Absolutely everyone below know what we must know to have the ability to help you.

Discourage it's possible, but rock wool would not halt rodents. I've discovered nests in remaining in excess of batts I'd piled up inside of a crawlspace.
Would these walls also take advantage of a variant of a soffit vent at their foundation, a 1” baffle on their own “outer”area to allow pure ventilation plus some form of ventilation tie-in to allow air to vent out from the attic’s ridge vent.

Thanks for offering the knowledge during the report and the element drawings and photos. Nice final result.
Since both heating and cooling arise for extended periods in mixed-humid climates, it might be difficult to figure out the correct technique for moisture Regulate. To include to your confusion, The American Culture for Heating, Refrigeration and air Conditioning engineers (aSHrae) and also the energy and environmental Developing Affiliation (eeBa) recommend that wall systems be permitted to dry towards the interior or exterior setting in mixed-humid climates and, if at all possible, make it possible for some drying in equally directions." Can they ever fail on account of unique RH conditions than Individuals described ?
This is able to puncture the vapor barrier and permit humidity to penetrate. Also putting the vapor barrier before the insulation might lead to condensation forming on the inside floor with the barrier In case the dehumidifier have been to fail. Perhaps not a huge danger but 1 The professionals give thought to? I could see they there would be gaps among the insulation and barrier leaving a surface for that condensation to kind. Do they make rigid foam with a decent fireplace rating? I’ve not observed that and would remove considered one of my more substantial concerns.
It seems like There's some kind of adhered flashing terminating the WRB that is in line with the element.
and spoke to Rockwool Customer support technological Division to verify this software for Climate zone 3a. In keeping with them they advised this assembly for my walkout basement.

Overall guess here, using rigid foam which has an approved fireplace rating could be a much simpler task.
