Fire rated doors are your building’s first line of defense when a fire breaks out. Think of them as strong, reliable guardians that compartmentalize a blaze, giving people precious time to escape and firefighters enough time to respond. These specially designed doors are tested under rigorous conditions to withstand high temperatures for a specified period—usually 20 to 180 minutes. Their main purpose? Preventing the spread of fire and smoke between compartments of a building.
