What is ROCK WOOL insulation used for?

Common Applications

Rock wool is very effective for use as insulation behind and around electrical boxes, wires and pipes. It can fill most wall cavities, leaving virtually no voids. It is also used as spray-on fireproofing material.

What happens if ROCK WOOL insulation gets wet? ROCK WOOL stone wool insulation is moisture resistant yet vapor permeable. This means that in the event the insulation becomes damp or wet, the insulation can be allowed to dry out.

Rock wool insulation can last 50+ years while maintaining its thermal and acoustic performance. Unlike some other insulation types, it does not degrade, settle, or lose effectiveness over time. Maintains its structure indefinitely—does not sag, settle, or shrink.
