Which list correctly identifies the four mineral wool insulation types?

• A. Pipe, Board, Batt, Block Insulation
• B. Board, Pipe, Foam, Block Insulation
• C. Pipe, Batt, Block, Foam Insulation
• D. Pipe, Board, Foam, Block Insulation

Answer: (A)

Mineral wool insulation is produced in several form factors to fit different installation needs. The four common types are pipe insulation, board insulation, batt insulation, and block insulation. Pipe insulation coats plumbing and piping runs to cut heat loss and prevent condensation. Board insulation uses rigid panels for walls, ceilings, and other flat surfaces where a solid, continuous layer is helpful. Batt insulation comes as flexible blankets that fit into framed cavities between studs or joists for thermal resistance with good fit and compression resistance. Block insulation consists of dense rigid blocks used for larger sections or specific applications like fire resistance or infill where a monolithic piece is desirable.

Other options bring in foam, which is a different category of insulation material (such as spray foams or foam boards made from polyurethane or polyiso), so they don’t count as mineral wool product forms.
