What should the door assembly rating be for a wall rated at 1.5 hours?

In fire-rated construction, the door assembly rating should match the rating of the wall in which it is located to ensure that it provides a similar level of protection and containment during a fire. Since the wall in question is rated at 1.5 hours, the door assembly must also be rated for at least 1.5 hours. This alignment is critical not only for code compliance but also for safety, ensuring that both the wall and door can withstand fire exposure for the same duration. Therefore, a door assembly rated for 1.5 hours is necessary to maintain the overall integrity of the fire-resistance-rated wall, ensuring that both components work together effectively to protect the space from fire spread.
