Commercial Doors 2023

Fire Ratings

Fire doors and their respective frames and hardware are rated by the amount of time, in minutes or hours, that a door can withstand fire in test conditions. Laws and regulations can vary widely between states, cities, townships and municipalities. Always be sure to check with all regulating authorities to ensure the door units you order and install comply with all applicable laws. Reeb’s commercial doors are stocked as Category “B” doors meaning they do not have a built-in system to comply with the positive pressure requirements. Therefore, all commercial doors are neutral pressure rated. Reeb can offer the Hollow Metal doors as positive pressure rated by supplying an intumescent strip that must be applied after installation and finishing. An architectural wood flush commercial door must be special ordered to have a positive pressure rating.

For more information on neutral and positive pressure rated doors please see page 25.
