Firemiser™ Insulated Fire Doors

Model ERD20

Firemiser Insulated Fire Doors 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: Buildings with planned expansion that will require the opening to be fire rated in the future, for exterior openings with building code required fire protection due to proximity of other structures or for interior fire doors where sound control is desired.
