Frequently Asked Questions (FAQs) About Fire Rated Doors
Fire-rated doors are critical components in any building’s passive fire protection system. As a fire rated door supplier, we know that these doors are engineered to contain and prevent the spread of fire and smoke, providing an essential barrier that allows safe evacuation and minimizes property damage. In this article, we’ll address frequently asked questions about fire rated doors and fire resistance doors, ensuring you understand their importance, regulations, and the necessary precautions for proper use.
What is a Fire Rated Door and Why is It Important?
A fire rated door is a door designed to prevent the spread of fire within a building. These doors are tested to withstand the heat and smoke from a fire for a specified period (e.g., 30 minutes, 60 minutes, or 90 minutes), and they help to compartmentalize the fire, keeping it contained in one area and allowing safe evacuation of people from the building.
Fire rated doors are a vital part of a building’s fire protection system, reducing the likelihood of widespread fire damage. By creating fire-resistant barriers, these doors provide an additional layer of safety and ensure compliance with building codes, especially for high-risk areas such as stairwells, corridors, and mechanical rooms.
How Long is the Certification of a Fire Rated Door Valid?
The certification of a fire resistance door depends on the third-party certifier’s standards. Typically, fire rated doors are certified for a period of 3 to 5 years. After this period, the door must be re-certified to maintain compliance with the relevant fire safety standards and regulations.
If a fire rated door’s certification expires, it means that the door no longer meets the prescribed standards, and authorities or project consultants will not accept it for use. In this case, delays or stoppages in construction projects may occur, as non-compliant doors would need to be replaced to meet project specifications.

Why Can’t You Change Single Components of a Fire Rated Door System?
Changing any component of a certified fire rated door system, even something as small as replacing a hinge or lock, can undermine its effectiveness. When a fire rated door is certified, it is tested as a complete system, including the door leaf, frame, seals, hardware, and glazing (if applicable). All components are chosen and tested together to ensure they provide the intended fire protection.
Replacing any component without specific testing and certification for that part can compromise the fire door’s integrity and reduce its ability to withstand fire. If modifications are needed, it’s crucial to consult with the third-party certifier to assess whether re-testing is required to maintain the door’s fire resistance rating.
Can a Fire Rated Single Door Certificate Be Obtained by Testing a Double Door?
This is a common question we hear as a fire rated door supplier. If a double fire rated door system is tested and certified for a specific fire rating, it’s possible for a single door with the same design and components to meet the same fire rating. However, this is not automatic.
The third-party certifier must evaluate the single door’s design and construction to ensure it matches the double door’s specifications. In most cases, re-testing is required to issue a separate certificate of conformity for the single door. Always consult with the certifier to ensure compliance with fire safety standards.
Can Fire Rated Doors Be Modified After Installation?
Once a fire rated door is installed, any modifications made without the approval of a third-party certification body (CAB) can render the door non-compliant with fire safety standards. This includes altering or replacing door components, such as drilling holes or changing the door’s locking mechanism.
If modifications are necessary, it is crucial to consult with the third-party certifier before proceeding. Depending on the scope of the changes, additional testing and re-certification may be required to ensure that the modified door continues to meet fire resistance requirements. Without certification, the door may no longer function as intended, jeopardizing safety and legal compliance.
Can a Small Glazing Element Be Added to a Certified Fire Rated Door?
Adding a glazing element, such as a vision panel, to a fire rated door can impact its performance. Before making any modifications, it’s essential to consult with the third-party certifier.
In most cases, the third-party certifier will require fire-test evidence that includes the same door design with the added glazing element. Fire testing with the new glazing installation will help assess whether the modified door meets the required fire resistance standards. If the addition meets fire safety standards, the certifier will issue a new certificate for the modified door.
Can the Thickness of a Certified Fire Rated Door Be Increased?
Increasing the thickness of a fire rated door to meet project specifications can invalidate the door’s existing certification. Fire resistance is a result of the careful combination of various components, including the door core, seals, glazing, and hardware. If the thickness is increased, these components may no longer work together as intended, potentially compromising the door’s ability to resist fire.
Before making any changes to the thickness of a fire rated door, it’s essential to consult with a third-party certifier. They will assess whether the changes require re-testing and re-certification to ensure the door continues to meet fire resistance standards.
