Fire and smoke must be stopped in their tracks to save property and, more importantly, protect lives.  Our advanced fire rated door systems compartmentalize a fire event quickly allowing adequate time for egress from the building. 

Our rolling fire rated doors have become the clear and reliable choice for building owners and designers who demand the highest level of life safety and fire protection available with the lowest cost of ownership in a modern, easily integrated package.  

All fire proof doors are custom built for everyday use. Designed for fire rated openings, our fire doors provide security and access control and are for use in openings that are not part of a required means of egress. Available with several optional materials and finishes, our fire proof doors have many ways to be customized to meet your fire solutions needs.

Our advanced Fire Door Closure Systems offer industry-leading, intelligent operation that:

  • Activate thermally or electrically to contain fire and smoke spread.
  • Easily - or even automatically - reset or auto open after a fire event or power outage

Optional SmokeShield® smoke and draft control conforms to UL1784 and assures that smoke will be compartmentalized with the fire and not spread quickly throughout the facility, allowing safe egress for occupants.

Our fire proof doors are Factory Mutual Approved, listed with the California Office of the State Fire Marshal, and are UL Listed for ¾, 1 ½, 3 and 4 hours of fire protection. These doors are designed for daily use to provide security and access control, and are approved for openings that are not required means of egress.

Our overhead rolling fire doors are custom built to your specifications in our standard service door configuration or in our Firemiser™  insulated rolling fire door version for climate control solutions. See how Cornell can help you with your fire rated garage door needs today.
