One of the only installers in California
Rockwool is very similar in performance to Cellulose, with two primary distinctions: flame-proof rather than flame-resistant (Cellulose), and able to soundproof airborne and vibrational sounds rather than exclusively airborne (Cellulose). Both are excellent products that you can’t go wrong with, but because Rockwool is priced at a premium rate, we recommend it primarily to homeowners who want to prioritize fireproofing or soundproofing. See more info on our ‘soundproofing’ page.
