HMMA FAQs - Fire-Rated Doors and Frames
Why is only a 1.5 hour rated door and frame required in a 2 hour rated wall?
Pierced walls (i.e. prepared to install door and frame) has a reduced fire rating.
Are gaskets required on fire doors?
Generally they are not, however, they may be required in smoke and draft control areas if such a requirement is adopted by local authority having jurisdiction.
How can I label existing doors and frames in the field?
Only by third party certification after field inspection. An inspector has the right and authority to request that frames be broken out of walls or doors and be cut open to expose their contents.
What are the basic hardware requirements for fire door assemblies?
They must have a minimum of approved hinges, a listed and labeled self-latching device and a labeled self closing device.
If hardware is labeled, does it mean it can go on any labeled door?
No, labeled hardware cannot go on ANY labeled door. For instance, an opening with VR x VR exit devices must use doors that were tested for this hardware configuration. Therefore, even though the exit device is fire tested, it cannot be used on doors that are designed for 8" Panic x VR.
