Two Hour Fire Doors
Design professionals occasionally request two hour fire rated doors. This often leaves distributors and manufacturers scratching their heads because there aren’t any US code requirements for a two hour door. We believe these requests may be due to a misunderstanding of the International Building Code® (IBC).
The IBC requires a higher fire rating for walls than for doors on the premise that combustible materials will be stored immediately adjacent to walls but not against operable doors. Doors located in stairwells or other enclosures of vertical passage through a building generally require 1 ½ hour door assemblies and 2 hour walls. This can be verified by referencing 2015 IBC® Table 716.5 or SDI-118 Table 1 (below).
Specifying a 1 ½ hour door rather than a 2 hour door is the way to go because it is an infinitely more common product.
New AIA Course on Security
The Steel Door Institute offers a number of free online courses that provide AIA or GBCI credit. We just published a new course that educates architects on the increasingly popular topic of building security.
Protect People and Property by Specifying Secure Doors and Frames
Every type of building requires protection against forced entry – and doors & frames are the first line of defense. Learn about finding the “just right” amount of security for your building projects and how to specify the doors and frames. This course covers:
