Our take on the UniTherm Mineral Wool Insulation, Gray, 27 ft, IR-3X27

UniTherm IceRock is a 3 ft by 27 ft roll of raw, non-combustible basalt mineral wool used for thermal and acoustic insulation. It is flexible, easy to cut and handle, and holds up in high-heat industrial and commercial settings where foam or fiberglass would fail. It is a bare roll with no facing or vapor barrier, so it suits people wrapping pipes, ducts, tanks or framing cavities who will add their own jacketing. Compared with faced fiberglass batts it resists fire and heat far better but is heavier, itchier to install and needs a separate air and moisture barrier.

Questions and answers

Does this roll include a vapor barrier or facing?
No. It is raw mineral wool with no facing, so you add your own jacketing, foil or membrane where a vapor or air barrier is required.
Can it be used around a wood stove or chimney?
Mineral wool is non-combustible and handles high heat, but clearances to combustibles are set by your stove and chimney maker and local code. Follow those listings and use the correct listed shield or wrap.
How do I cut it?
A serrated insulation knife or bread knife slices it cleanly. Compress the roll slightly and cut to width; it springs back to fill gaps.
Is it safe to handle without gear?
Wear gloves, long sleeves, eye protection and a respirator. The fibers irritate skin and lungs, and dust should be kept out of living spaces.
Will it work for soundproofing a wall?
Yes, it absorbs sound well inside stud cavities, but it does not replace mass or decoupling. Pair it with added drywall layers or resilient channels for real noise reduction.
How much area does one roll cover?
The roll is 3 ft wide and 27 ft long, about 81 square feet at its stated thickness.
