Auto Fire-Tite® IMB Coiling Fire Door

Quality Fire Rated Doors

Alpine’s Auto Fire-Tite® IMB is a coiling fire door that has the same features as the Auto-Fire Tite® with the addition of IMB V7 slats for sound and thermal insulation. The Redi-Reset feature of this door eliminates the complication of a manual reset after drop testing or activation. The counterbalance assembly is state of the art, which allows for ease of use as well as maximum security. This high quality fire rated door is designed to prevent the spread of fire or smoke between compartments. They are meant to enable safe egress from a building, structure or ship. See the fire door photo below.

These Fire Rated Doors, Coiling Fire Doors and rolling fire doors are built for performance, especially for applications where fire protection is of primary concern. Alpine’s fire rated door undergoes several fire tests (see test below in the fire door photo)  in order to ensure reliability during extended periods of exposure to fire. The coiling fire door is built to meet or exceed industry standards and is built in accordance with requirements specified by Underwriters Laboratories Inc. The Auto Fire-Tite IMB is labeled for up  to 4 hours of fire protection by UL.

Above you will find a fire door photo gallery that showcases examples of the automatic Fire Rated Door, Coiling Fire Door, and rolling fire door. Alpine has manufactured and installed the fire rated door in a wide array of industrial and commercial applications.
