How to insulate and soundproof with least emissions/toxicity?
We live in zone 3C, and we’re thinking of putting Roxul between studs of interior walls we want sound-proofed along with double sheetrock and Green Glue to bind staggered sheetrock panels together. For external walls we’re trying to decide between a denim insulation or Roxul. The house originally had a moisture barrier on the outer side of the studs on the exterior walls and close to the house side in the attic.
My husband and kids have allergies, and my husband is very sensitive to smells. My kids both have larger health conditions as well, so we’d really like to avoid anything that may continue to emit gases or reduce the air quality inside the house. At the same time, sound-proofing interior walls is a priority, and we’ve gotten mixed and possibly out-dated messages about how or if to insulate the exterior walls.
Are the above good products to consider? Should we move or remove this vapor barrier? Will it be better for us to insulate the exterior walls or not? If using Roxul, is Safe n Sound the cleaner option and a better choice than the other Roxul for both interior and exterior walls?
Thanks so much for any advice or information you can share.
