INSULATED ROLL UP FIRE DOOR SYSTEMS
Our Firemiser Insulated Fire door combines the functionality of the rolling fire door with the benefits of an insulated service door.
In the event of a fire, the fire door functionality of this door allows it to save lives and protect property. The fire door works to compartmentalize a building to eliminate the spread of smoke flames, keeping the fire isolated.
The mineral wool used to insulate this door, helps to control sound transmission – featuring an R value of 5.3 and a U Value of .189 based on the ASHRAE Handbook of Fundamentals. The insulation also helps in a climate controlled environment by helping to maintain a different temperature on the interior and exterior of the door.
A Firemiser insulated fire door is perfect for an application that is currently exterior, but there is a planned expansion that will require the opening to be fire rated in the future.
Our insulated rolling fire door is UL listed, Factory Mutual Approved and listed with the California Office of the State Fire Marshall. It is listed with a protection ratings of 45 minutes, 90 minutes, 3 and 4 hours.
Our fire rated insulated rolling doors are also available with a SmokeShield® seal package. This optional package controls smoke and drafts while conforming to UL1784. This seal package will ensure that the smoke will also compartmentalized with the flames.
A standard UL labeled door is available up to 13.5’ wide by 12’ high.

"We are very pleased with the performance of the Cornell doors. Throughout the area, doors are blown out everywhere and the building we just moved from was destroyed. Here, our $2.3 million of inventory was saved. Being satisfied with the Cornelldoors is an understatement!"
ROGER WEIR, OPERATIONS MANAGER AT LEWIS BEAR COMPANY
"CornellCookson had installed a rolling door for us in our old building. We used it all the time and it’s held up really well over the years. Calling them in again made perfect sense. We are thrilled with how this door looks. The level of detail that’s been captured so clearly on this large door is incredible. It’s exceeded our expectations by far and will definitely do its job as a focal point in our new building."
MARK WORMAN, OWNER OF GRAVEYARD CARZ
"The existing grilles we had installed prior could not stand up to the cycle usage, and they needed a lot of maintenance. Cornell's Extreme Performance 324 grille is the right product, far superior to the other grilles we had in this opening before. We are really happy with the performance and will definitely purchase this product going forward, when the next opportunity arises."
MARK ARGABRIGHT, FACILITY MANAGER AT YOHN PROPERTY MANAGEMENT
"Not only was functionality a major concern, but we also needed a custom closure solution that worked with the overall exterior aesthetic of the building which is rooted in neighborhood context. We collaborated with CornellCookson to develop a solution that is both functional and architecturally sensitive."
EUGENE FLOTTERON, CETRARUDDY ARCHITECTURE
"The SteelWeave Metal Mesh Grille was the perfect solution to meet all of our needs. It complimented the design of the bar and lobby while adding some elegance. We could not be happier with the look and function of our CornellCookson SteelWeave Metal Mesh Grille and custom sliding panel."
