About Fire Rated Doors


Fire Doors are doors with fire-resistance rating and play an important role in fire protection and loss prevention. They are used as part of a passive fire protection system to reduce the spread of fire or smoke between compartments. Fire Doors enable safe escape from a building or structure during events like fire, earthquake, etc. Since Fire Doors have a distinct purpose, they have additional special characteristics than those of ordinary doors.

Ease of Access

Since fire doors are meant to be the safest exit points in cases of fire, they are usually painted with bright red color to be visible during emergency, and are often attached with push bars for ease of opening during fire panicking.


In interior application to separate compartment zones, Fire Doors are most of the times required to be fitted with vision panels so that flames or smoke may be seen and collisions avoided.

Fire Rating

The most important attribute of Fire Doors is its fire rating. Fire rating is the door’s capability to withstand fire and remain intact for the duration. Fire rating is measured in minutes (sometimes hours) the fire door was able to maintain integrity while subjected to fire.

Air Tightness

Fire Doors serve as the access between the safe egress and a burning compartment, it is therefore important that fire doors do not permit smoke to the safe side. Fire doors are fitted with smoke seals to address this factor.


Although not as important as the other attributes, fire doors that reduce sound levels are sometimes requested. Acoustic fire doors are usually installed in schools, theaters, studios, etc.
