Buy Rockwool Instead
This mineral wool is poorly made. some bats had large areas that were only 1/2" thick (if even). It falls apart when trying to install. I tried 3 bags but grew more and more frustrated. Finally rockwool was back in stock and it is a far superior product.

    Too flimsy
    I'm glad I bought only one pack to test it first. This product is too flimsy and falling apart in hands. It may work on supported walls if you'll hold it carefully, otherwise it's breaking into smaller pieces.

      This is a fibrous material shaped like fiberglass insulation. The similarity ends there people. Its more like dry sheet cake. I bought a cheap bread knife to cut it. Works better than a razor by far. We used this in new construction walls where bedroom walls were next to living spaces.

      Fairly easy to install. Tears easy enough, but what a difference. I installed in the ceiling of my basement office to try to cut down on the noise from the kitchen above. I would say it cut out 30% of the noise level. Going to add another layer to see much more I can improve it.

      The product was easy to install. I believe by its composition it will definitely make a difference in sound. However, my house is not yet competed so I have no actual use to comment on.

      full of tiny metal beads
      Easy enough to cut and install in walls. BUT be careful of tiny metal beads/particles that are all throughout the insulation if you’re working around anything important, like say a new porcelain tub...also it’s very itchy; not as bad as fiberglass insulation but still bad enough to irritate skin, nose, eyes.

        It Just WORKS
        I have no complaints about this product. It works! Recently installed this in a basement ceiling and its great! Renovated a bedroom in the basement and it helps with keeping out the people talking above the room. I love it.

          Over Priced, Poor Quality, Full of Rock, Falls Apart
          The quality was very disappointing for the price point. The very first bag I opened had Chunks of rocks falling out of the batting. Crumbling product. Was supposed to be 3 inches seemed like only 2 and half at most. Felt cheated.

            I"m using the product in a recording studio build. I'm using it to keep the outside noise out. So far it's been very easy to manage and install.
