Mineral Wool IMPs: Sustainable Fire-Resistant Construction

Mineral wool core panels provide an excellent alternative to foam core insulated metal panels and other traditional materials where the wall assembly need to be fire resistive. Ratings of up to three hours can be achieved by this product. These panels also provide all necessary control layers in a single component: air, vapor, water and thermal. Acoustic properties of the product are also evaluated. Product configurations including sizes, profiles and metal facings are studied. Code compliance and generic details are reviewed. Mineral wool core panels and their contribution to LEED credits are also studied.
