It can be non-faced or faced from one or both sides with reflective vapor retarder reinforced aluminum foil; it meets the technical requirements of ASTM C 553 (Specification for Mineral Fiber Blanket Thermal Insulation for Commercial and Industrial Applications).

Application It is designed for high thermal resistance applications for the cold and hot services such as cold stores, storage tanks, boilers, ovens, chimney walls and heated ducts etc.
Storage It must be stored in an area where it is protected from water exposure and physical damage.
