The Fire-Storm® IMB is a combination of the features of Alpine's Redi-Storm® and Fire-Tite® IMB models. It is Dade County Approved for high windloads (up to 187 mph) as well as UL and MEA approved for fire protection. It comes in galvanized or stainless steel and in a variety of different finishes.

Fire-Storm® IMB curtains are constructed of insulated 7/8" thick slats, and can be finished with powder coating or baked enamel finishes. The metal on metal insulated slats have a 7/8" foamed-in-place urethane core which bonds the metal skin and strengthens the slat. Each door is equipped with a 22 gage steel hood formed to fit the contour of the end brackets and durable ductile iron windlocks with 1/4" semi-solid rivets. Our door supports and brackets are all steel plates no less than 1/4" thick. Alpine's Torsion Counterbalance Assembly is state of the art, providing maximum security and ease of use.
