Medallion 450 Fire Doors
Classified for openings rated up to 1-1/2 hours (90 minute) which have 450˚F temperature rise restrictions.
A temperature rise rating is not a requirement for qualification as a labeled fire door, but, when required, doors are built to meet this criteria Ceco manufactures two types of temperature-rise rated fire doors.
Medallion 450 is a temperature-rise rated door which allows the unexposed side of the door to reach a maximum of 450˚F during the first 30 minutes of testing.
Temperature-rise rated Fire Doors allow people to pass by the door safely when fire is on the other side. When an opening is required to retard the transmission of heat from one area to an adjacent area, a temperature-rise rated door is required. These doors are typically required in locations such as stairwell access doors, electrical control rooms, paint storage, etc. Temperature-rise designations indicate the maximum rise in temperature above ambient on the non-fire side of the door during the first 30 minutes of exposure in a standard fire test.
