Insulating Panel and Door Systems
INSULROCK® brand insulating panels are stressed skin sandwich panels consisting of steel, aluminum, or fiberglass reinforced polyester facings permanently bonded to a ConRock™ brand structural mineral fiber core with a heat polymerizing adhesive.
INSULROCK® panels look like ISOWALL™ brand insulating panels and can have similar facings and joint treatment so they can be used together when appropriate. The difference is the core. INSULROCK® has an inorganic core consisting of fibers of volcanic rock. INSULROCK® panels have achieved up to a Three Hour Fire Resistance Rating when tested by ASTM E119 (UL263).
Unlike plastic foams such as expanded polystyrene, polyurethane foam, or cellular modified isocyanurate to polyisocyanurate, ConRock does not burn. In fact, mineral wool is often used for fire protection of steel. An INSULROCK®
panel with steel or aluminum facings is almost entirely inorganic. The only organic materials in a typical wall assembly are a small amount of binder in the mineral wool, the panel laminating adhesive, and any joint sealant used.
