A fire resistant, or fire rated door is a door that is specifically manufactured to help prevent the spread of fire and smoke during a fire outbreak or incident. Made out of usually metal, fire-rated doors are more common in commercial settings but are also present in residential buildings.

Fire rated doors will help slow down the spread of fire and smoke, although they are not completely invulnerable to fires. Fire rated doors can still combust, under recurring pressure of fire elements that might compromise its molecular integrity. Overall, fire rated doors can help reduce the endangerment of lives and damage to property.

Nevertheless, fire rated doors are not supposed to combust during a certain time frame, in an average fire. While timings may vary, fire doors contain standardised ratings in intervals of 30mins. For example, a 2-hr fire rated door can withstand heat, flames and burning down for at least two hours. Ratings run from 45min to 3hours of fire resistance.

In Singapore, fire rated doors cost an average of $900-$1100 to manufacture and install, depending on the grade of the fire rating.

Some building codes require a fire-rated door between working areas (like a garage) and office space.
