I didn’t know that rockwool was still manufactured. Last time I saw it was over 30 years ago pulling it out of the walls of a 50 year old house for a remodel.

The new form of mineral wool or rockwool is Roxul and other brands. It is not asbestos and I have not heard any health problems. It comes in 4-foot batts, rigid boards, or loose that can be blown in. Fireproof, holds its shape if it gets wet, good sound absorber, as insulation it is 3.8-4.3 R per inch.

We put it in the interior walls of our bathroom and you can barely hear the toilet flush or the shower on full blast. Easy to install. Home Depot usually caries it in single packs of 12 batts, enough to do a 8x8 area.

Still available and very good insulation. Roxsul is one brand name. The material has better soundproofing quality than fiberglass and it is both water repellent and fireproof.
