Temperature Rise Doors

Temperature Rise Door Applications

In the event of a fire, temperature rise doors minimize the heat transfer to the non-fire side of the door. This allows people to safely pass below the floor of fire origin in a burning building.

Temperature rise doors are commonly found in the stairwells of high-rise buildings such as offices, hotels, school dormitories and apartment buildings.

Temperature rise ratings are 250°F, 450°F, and 650°F, which indicates the non-fire side of the door will not exceed that temperature for 30 minutes. The 250°F temperature rise designation is the most stringent rating of the three because it allows for the least transfer of heat.
