Fire-Rated and Smoke-Rated Products



Cornell offers many types of fire door closures and solutions including fire-rated doors, fire rated shutters, rolling fire doors and more. Combined with our AlarmGard or FireGard advanced fire closing systems, we have all the products you need to help protect lives and save property.


Our Fire-rated doors are custom built to your specifications. Designed for fire rated openings, our steel fire doors provide security and access control and are for use in openings that are not part of a required means of egress. Factory Mutual Approved and listed with the California Office of the State Fire Marshall. UL listed for fire protection ratings of ¾, 1½, 3 and 4 hours. Our advanced Fire Door Systems offer industry-leading, intelligent operation and will:


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



Our Firemiser insulated fire door provides energy savings, sound attenuation and climate control with an STC rating of up to 32, and a flame spread and smoke development index of 0.

Fire-rated rolling counter shutters, also known as fire-rated counter doors, secure openings using smaller (and more aesthetically pleasing) guides, slats, brackets and hoods than traditional rolling fire doors. Rated counter shutters protect interior corridors and create barriers for openings where life safety is a priority and can fully close to the floor when compact door components are desired.


SmokeShield® Counter Fire Shutters: Add optional UL Classified smoke and draft control to counter fire doors. Containing smoke saves lives and building property and also aids in fire containment by slowing oxygen flow to the fire source. It's simple to double up on the protection of your building and may be required by your local building code.
