Cornell Ironworks

Cornell Iron Works has been owned and managed by the Cornell family since 1828. In the 19th century, we were a manufacturer of specialty ironwork, grates, railings, stairs, vaults and structural and ornamental ironwork. The company originated in New York City serving a regional market then later New England and the middle Atlantic states.

Today, with manufacturing and corporate offices located in Mountaintop, Pennsylvania, we are a leading resource for rolling steel doors and grilles. We still serve the non-residential construction market, but now our customers and distribution covers North America and beyond. Today’s emphasis is not only on rolling doors and grilles, but also on product support and information services to assist professionals that design, build or manage industrial, institutional and commercial buildings. With our commitment to quality products, materials, design and construction methods that enhance security and life safety, we provide success opportunities for our distributor, architect and contractor customers.


Firemiser™ Insulated Fire Doors


One Door - Many Benefits

Provide UL rated fire protection plus security, sound attenuation, environmental separation and smoke control with the Firemiser insulated fire door from Cornell.

Achieve Rolling Steel Security with up to 4 hours of UL Classified Fire Protection, plus:

  • Sound Attenuation - A Sound Transmission Class rating of STC 27 (based on testing a complete, operable door assembly) makes Firemiser's mineral wool insulated curtain an excellent choice to maintain fire wall integrity and reduce decibel levels.
  • Climate Control - Firemiser's insulated curtain yields a 5.3 R-value that can be combined with full perimeter seals for use at exterior or interior openings whenever fire protection and environmental separation is required.
  • Smoke Control - Add optional UL classified smoke and draft control to 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.

Practical Design Applications

  • All fire wall openings where the door is to be closed regularly and a sound attenuation need exists. Exterior openings that require a fire rating due to the proximity of other structures or combustible materials.
  • Buildings designed for future expansion where current exterior wall openings are to become interior fire wall openings.
  • Interior fire wall openings where the door will be normally closed to control varying climatic conditions between two areas.

  • cooksonex2

    The Cookson Insulated Fire Door is used when an opening in a fire wall requires a door that will reduce energy costs as well as serve as a normal fire door. Cookson insulated fire doors have a 4 hour, 3 hour, 1 ½ hour and ¾ hour rating and can be mounted on concrete, masonry, structural steel and structural steel and gypsum board walls.

    Known for its contemporary styling and reliable performance, Cookson's rolling counter fire doors provide the same degree of fire protection as the full-sized rolling service fire door. As with Cookson standard counter doors, counter fire doors are engineered with properly sized components and trim.

  • cooksonex4

    Cookson's single unit frame and curtain counter fire door consists of a completely unitized frame, custom built for pass windows, ticket windows or counter openings. This unit need not be installed as the wall is erected, but may be installed after the wall construction is complete, thus eliminating scratches and dents resulting from other construction activity.

    When combined with either of Cookson's Fire Door Product Systems, the Counter Fire Door with Sill and Trim completes the fire protected installation. This cost-effective unit simplifies installation requirements and the need for additional trim to finish the opening is eliminated.

  • cooksonex5

    The compact Cookson Smoke Control Door is designed to obstruct the spread of smoke from one area of a building to another.
