No matter if you own an individual home or an apartment, no one is completely protected from the risk of a possible fire. Residential fire-rated doors, however, can bring an added level of safety by protecting both occupants and material goods. In this article, we will explain in greater detail how these doors work and the different options available on the market.
What is a Fire-Rated Door?
By definition, a fire-proof door has a safety feature that is designed to help prevent fire and smoke from spreading from one space to another. It protects from flames, but also from smoke and toxic gases. This type of door stands out by its structural integrity. Moreover, it is generally recessed and insulated with an airtight fire-retardant product.
How the Door Works, in the Event of a Fire
When a fire starts to spread, the interior fire-rated door acts as a protection barrier. It generally has an automatic-close mechanism, that shuts the door to prevent flames from spreading. You will be able to cross the door, but it will quickly close to prevent the flames from spreading.
Use and Advantages of Residential Fire-Rated Doors
Although they are very popular in commercial buildings, a residential fire-proof door also offers several advantages. The first is, of course, saving lives. By slowing down the fire from spreading, these doors provide occupants with more time to evacuate their home.
It can also help limit material losses by insulating the rooms more efficiently. Even though they only slow down the flames from spreading temporarily, this added delay gives firefighters more time to intervene.
Fire-Rated Doors, Certifications and Standards
Fire-rated doors must comply with specific standards. The manufacturer must obtain a certification like, for example, from the ULC, ensuring that the doors comply with these standards. They are rigorously tested through fire simulations and different constraints.
There are different grades of fire-retardant doors that are established according to how long they can withstand fire. A residential fire-rated door must be able to withstand fire for at least 20 minutes in order to receive the certification.
Different Types of Fire-Rated Doors

Metal Fire-Retardant Doors
Steel or aluminum doors are very common in high-risk zones given their superior resistance when it comes to fire safety. They generally protect over a longer period of time. They are often preferred in commercial buildings.
Other Fire-Resistant Materials
As a general rule, fire-resistant materials include glass and fiberglass, ceramic and gypsum, among others. At Dörr Industries, our 20 minutes approved custom-made fire-rated doors are both esthetically pleasing and functional.
Installation and Maintenance
Proper Installation of a Fire-Proof Door
The efficiency of a fire-rated door when it comes to protection mostly depends on its installation. The door must be perfectly adjusted within the frame and openings must be sealed. Our doors are easier to assemble than traditional models, making the whole process much easier for you. If you need extra help, don’t hesitate to call on professionals.
Regular Inspection and Maintenance
To ensure that your fire-retardant door is working properly when you need it most, inspect your doors regularly by double-checking the auto-closing mechanism, the integrity of the joints and by making sure there are no visible signs of damages.
Replacing Used Fire-Rated or Non-Compliant Doors
Fire-proof doors can become less efficient over time. As soon as they begin showing signs of wear or no longer comply with the necessary standards, it is important to replace them.
