- EntryDefender™ High-Security Door: The EntryDefender™ Door meets the U.S. Department of State Standard for forced entry for a five-, 15- and 60-minute mob-style attack.
FIRE-RATED ROLLUP SERVICE DOORS
Rollup fire doors are rated structural fire barriers that help block the spreading of hazardous fire and smoke by compartmentalizing a building space and keeping the event isolated. Many buildings today mandate the placement of rolling steel fire doors as a standard safety precaution.
The Firemiser Insulated Rolling Fire Door is perfect for an exterior application and reduces sound transfer thanks to mineral wool insulation. Mineral wool insulation also minimizes thermal transfer, which can help you with temperature control inside your building. Opt for the SmokeShield™ seal package for your fire-rated door if you’re required to conform to UL 1784 or want an additional barrier to eliminate smoke migration throughout your building.
