Reply To: Is rockwool dangerous?

[JJ WrightParticipant]

My understanding is that rockwool is generally considered very safe (certainly moreso than fiberglass insulation), though there is some minority disagreement on that. Here's one study which concluded it's safe on at least a short term basis: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2711883/

In any case, even if there is a long term risk, that risk is going to come from breathing in loose airborne fibers. As long as your panels are wrapped in an outer fabric, I wouldn't imagine that to be a serious concern since the wrap should keep the fibers from becoming airborne.
