Which type of insulation is MOST likely to absorb and hold water?

• A. Mineral Wool
• B. Cellular Glass
• C. Calcium Silicate
• D. Fiberglass

Answer: (A)

Mineral wool insulation is most likely to absorb and hold water due to its fibrous composition and porous nature. It is made from natural or synthetic materials that can trap moisture, making it susceptible to water absorption. When mineral wool insulation becomes wet, it can lose its insulating effectiveness and may lead to issues such as mold growth or corrosion if used in applications exposed to moisture. Cellular glass, on the other hand, is a closed-cell insulation that is water-resistant and does not absorb water. Calcium silicate insulation, while it can retain some moisture, is designed to be more resistant to water than mineral wool. Fiberglass insulation is also less likely to absorb water effectively because it has a lower moisture-retention capacity compared to mineral wool. Thus, mineral wool is the best choice among the options for insulation that holds water.
