Can this be use for External Wall and Sound proofing both?

Asked by: Nik Patel
We used this product in our garage that had 2x4 construction. We used on the whole outside walls. We had a very cold winter and are really happy with it.

Can this product be used as a sound proofing

Asked by: Dannoooooooooooo
Yes, although a proper insulated wall would also use resilient channels and a sound insulation. Still, just insulated an interior wall with it and it does muffle the sound effectively.

Fiberglass Insulation R14 - 78,33 sq.ft. is rated 4.0 out of 5 by 2.
Rated 3 out of 5 by from It's ok but quality isn't great. Bought two packs and both had some weird mold like substance growing on some of the pieces. I was in the middle of insulation and didn't want to go through the hassle of returning it. Luckily I could afford to cut off pieces with the mold. Don't think I would use this again.

Rated 5 out of 5 by from Great insulation product Easy to cut and install. It does not fall apart when being cut. We also wanted a product that had a higher R-rating than just R12 (to fit between 2’x4’s) and this product comes in R14.
