WH 1 Hr Temperature Rise metal Doors Brief Introduction
A temperature rise metal door is a fire-rated door that limits the heat transfer through the door for a period of 30 minutes.
Temperature rise ratings indicate the maximum rise above ambient temperature on the non-fire side of the door, and will be either 250°, 450°, or 650° F.
The 250° door is the most restrictive because it limits the heat transfer to only 250° for a 30-minute period.
