What Are 2 Hour Fire Doors?

A 2 hour fire door can seem confusing, especially if you are familiar with the common fire door ranges. The most common fire doors can range from 20 minutes for interior wood fire doors, 90 minutes for interior steel fire doors, and 3 hours for exterior steel fire exit doors. Many walls are fire rated for 2 hours. 2 hour fire rated walls require 1-1/2 hour or 90 minute fire rated doors. Any fire rated wall will require a fire rated door. These fire rated doors are often located in stair wells, boiler rooms, or exterior walls that may have the potential for fire exposure from the outside of the building. A fire rated door such as a 90 minute fire door means that the door is rated to withstand fire for up to 90 minutes.
