Rockwool Insulation in Pocatello, ID

Rockwool, also called mineral wool, is made from stone fibers. It's naturally fire-resistant, doesn't absorb water the way fiberglass does, and is dense enough to noticeably cut sound between rooms and floors.

We install Rockwool batts in exterior walls, basement walls, interior walls for soundproofing, and around utility rooms and garages where fire resistance matters. It cuts cleanly and fits tightly, which means fewer gaps than standard fiberglass.

Rockwool doesn't air-seal on its own, so we often pair it with spray foam at the rim joists and air sealing at top plates for the best performance.
