Our take on the UniTherm Mineral Wool Insulation, Gray, 24 ft, IR-3X24

The UniTherm IceRock IR-3X24 is a 3 ft by 24 ft roll of raw, non-combustible basalt mineral wool used for thermal and acoustic insulation. It is made from bio-soluble Icelandic basalt, which UniTherm says gives consistent density and performance. The roll is flexible and easy to cut, so it wraps pipes, ducts and irregular cavities better than rigid board. It suits industrial and commercial work where fire resistance matters; for a simple attic job, common fiberglass batts are cheaper and easier to find.

Pros
  • Non-combustible basalt mineral wool
  • Flexible roll handles curves and odd shapes
  • Good thermal and acoustic performance
  • Holds up in high-temperature settings
  • Bio-soluble fiber, lower irritation than older mineral wools
Cons
  • Raw roll, no facing or vapor barrier
  • Fibers still irritate skin and lungs; wear PPE
  • Heavier and denser than fiberglass batts
  • Needs cutting tools and careful fitting
  • Less common in retail stores than fiberglass

Questions and answers

Is this the same as fiberglass insulation?
No. It is stone wool spun from basalt, so it resists fire and higher heat than fiberglass and absorbs sound better. It is denser and heavier, and it costs more than basic fiberglass batts.
Can I use it in a house attic?
Yes, but it is a raw unfaced roll, so you would add your own vapor barrier in most climates. For flat attic floors, standard batts are easier to fit and cheaper.
Does it need a vapor barrier?
The roll has no facing. In walls and ceilings, add a separate vapor retarder per your local code. On pipes and ducts, wrap with a jacket suited to the surface.
How do I cut it?
Use a serrated insulation knife or a fine-tooth saw blade and compress the roll slightly while cutting. Wear gloves, long sleeves and a respirator.
Is it fire rated?
The wool itself is non-combustible. The fire rating of a finished assembly depends on how it is installed, so check the assembly listing for your application.
