It’s worth the extra cost

 Would Recommend

Good for soundproofing. Easily cuts with a serrated knife. I used for attic insulation on 5-1/2” rafters. More expensive than the pink stuff but significantly less skin irritation.

Rock Wool insulation

While rockwood is expensive, I do like installing it better than regular insulation
