Chart of Door Fire Ratings and Labels

As previously indicated, doors are branded according to how long (in hours or minutes) they are anticipated to offer protection. A letter-rating that correlates to the time-based ratings may be seen on certain extremely ancient doors. We have included the letters in our chart below for reference, but current projects should utilize time-based ratings.

“Limited to the maximum area tested.”

Additionally, doors may have a temperature rise rating in degrees. This displays the anticipated surface temperature on the door’s inside after 30 minutes of exposure to fire. This will be labelled as being 250°, 450°, or 650°. Any glass that is a part of the door must also meet the standards for temperature increase.


S-Label or “Smoke Rating”

S-Labels are required by several regulations for specific doors in particular occupancies. For instance, smoke protection is frequently needed for corridor doors to stop smoke from entering or escaping from an occupied location.

A “smoke rating” is not exactly what an S-label is. The S-label instead certifies that the door passes the air leakage testing required by UL 1784: Standard for Air Leakage Tests of Door Assemblies and Other Opening Protectives. But if air cannot seep through the door assembly, smoke cannot travel through. Installing UL-certified gasketing is typically how an S-label is obtained.

Required Door Ratings Based on Partition Rating

Based on the rating of the barrier or partition that the door is in, the required door rating is determined. The building code should be consulted owing to the difficulty in calculating the rating of the partition and the permitted kind of opening; however, the table below offers an overview. 


The International Building Code has a comprehensive list of standards in Table 716.5. Local laws may differ.

There are several benefits of fire-rated doors

Safety: Fire-rated doors provide an additional layer of protection in the event of a fire, slowing the spread of smoke and flames and giving occupants more time to evacuate

Compliance: Many buildings are required by code to have fire-rated doors, so installing them can ensure compliance with local building codes and regulations.

Having fire-rated doors can potentially lower insurance premiums, as they can reduce the risk of damage and liability in the event of a fire.
Durability: Many fire-rated doors are also equipped with weather stripping and thresholds to improve the insulation of your home and reduce energy costs.

Where you Need Metal Hollow Fire-Rated Door Repair Or installation?


Fire Doors can help in preventing the fire’s spread. Despite what you have heard, not all doors are fire doors. Fire doors, however, are specifically designed doors that allow blocking access to some areas of a building from people in the case of a fire.

This might appear strange. However, fire doors are made specifically to be able to endure extreme heat. A fire door’s purpose is to compartmentalize a building’s areas so that, in case of fire, the room it is in will prevent the fire from spreading quickly. Fire doors are essential safety features.

Fire doors are smart technological devices. They use the fire against itself in this way. Fire doors are usually composed of solid wood and have a fire-resistant coating applied.

A fire door is a specific kind of door designed to stop a fire from spreading throughout a building. The door acts as a physical barrier against the fire. Fire doors are made up of fire-resistant metals because they must be extremely strong and fire-resistant to work effectively.

Checking the certification label is one of the most authentic ways to check if the door is a fire door or not. All fire doors must have a certification label because it verifies whether the doors have undergone sufficient testing to determine their level of fire resistance. The top edge of the door leaf is  usually where you’ll find these labels.

Your company’s management will have designated a “responsible person” to make sure that they check all equipment. There will be a lot of employees in your company who are qualified to perform this, but only one person should be in charge of inspecting the doors and handling any other fire responsibilities every six months (at least).

The FD30 and FD60 are the two primary fire door types. The letter FD stands for “fire door,” and the number that follows indicates how many minutes it can withstand a fire. As an illustration, FD60 withstands fire for 60 minutes.

The government has its own recommendations on the number you should have. They recommend having one fire door for a maximum of 60 persons. They recommend two fire doors once there are 600 employees. If you feel comfortable with more, you can have more also.

The door’s thickness and intumescent seal enable it to hold fire for long enough for people to exit the building safely.

Yes, you can use any high-quality product to paint or varnish your fire door.

Realistically, it would depend on the degree of the door’s damage, which can only be determined by a qualified person. To be on the safe side, we suggest buying a new fire door if the damage to the door is visible.
