Corridor Door - Gaps
Publish | January 01, 0001
What is the minimum gap requirement for smoke resistive corridor doors?
The Joint Commission allows gaps not exceeding 1/8 inch for meeting edges of door pairs as acceptable for a smoke resistive corridor door. Life Safety Code NFPA 101 (2000 edition) 18/19.3.6.3 simply requires that the door is smoke resistive. The 1/8 inch gap criteria is TJC criteria for uniform, consistent application to be used by surveyors and organizations when evaluating smoke resistive door assemblies. The door undercut is not to exceed 1 inch. Gasketing to reduce or close the gap can also be used if the door is not a fire rated door. Closing the gap with gasketing material would be prudent.
