Our take on the UniTherm Mineral Wool Insulation

UniTherm IceRock is a 3 ft x 6 ft roll of raw basalt mineral wool for thermal and acoustic insulation. It is non-combustible and bio-soluble, made from high-purity Icelandic basalt, and stays effective in hot industrial and commercial settings. The flexible roll is easy to cut and wrap around pipes, ducts and irregular cavities. It is a bare material, not a finished batt with a facer, so it suits builders and fabricators who add their own facing or cladding. Against glass wool it holds up better to heat and moisture; against foam boards it wins on fire resistance but is heavier and needs skin and lung protection when handled.

Questions and answers

Is this mineral wool fire rated?
The wool itself is non-combustible basalt mineral fiber, so it will not add fuel to a fire. The fire rating of the finished assembly depends on how you face and install it.
Can I use it for soundproofing a room?
Yes. It absorbs sound well when packed into stud cavities, ceilings or machine enclosures. Seal gaps and add mass layers for the best result.
Does it need a vapor barrier?
The roll is bare wool with no facer. In walls and roofs, add a suitable vapor barrier or facing on the warm side to control moisture.
Is it safe to handle without gear?
Wear gloves, long sleeves, eye protection and a dust mask. The fiber is bio-soluble, but it still irritates skin and airways during handling.
How do I cut it to size?
Use a sharp insulation knife or serrated blade against a straight edge. Compress the roll slightly as you cut for a clean edge.
Can it insulate hot pipes and ducts?
Yes, it suits hot-service pipes, ducts and tanks in industrial and commercial settings. Wrap it and cover with cladding or jacketing.
