What Are Fire Door Ratings?
Fire doors are tested and rated based on how long they can withstand the spread of fire. The rating is measured in minutes or hours, indicating how long the door can resist fire and heat before it fails.
Common fire door ratings include:
-
20-minute fire doors
-
30-minute fire doors
-
60-minute fire doors
-
90-minute fire doors
-
3-hour fire doors
Each rating offers different levels of protection, and understanding these ratings is essential for ensuring the right level of safety for your property.
Why Fire Door Ratings Matter
The fire door rating you choose will depend on several factors, including the location, purpose of the building, and local building codes. Here’s why choosing the right fire door is so crucial:
-
Prevention of fire spread: Fire doors help prevent fires from spreading from one area to another, giving occupants more time to escape.
-
Property protection: They protect the building’s structure, reducing the risk of costly fire damage.
-
Life safety: Fire doors are an essential part of building safety, helping save lives by containing fires to one area.

Fire Door Ratings: From 20-Minute to 3-Hour Protection
20-Minute Fire Doors: The Basic Protection
A 20-minute fire door is typically used in areas where fire risks are minimal, and the primary goal is to slow down the spread of fire and smoke. These doors are often used in:
-
Internal applications: Such as corridors or office spaces where the fire risk is lower.
-
Low-risk areas: Like residential buildings, especially in parts that are not near kitchens or other high-risk zones.
While they offer basic protection, 20-minute fire doors are not suitable for high-risk or high-traffic areas. They are ideal for ensuring home fire doors comply with safety standards without the added cost of higher-rated doors.
60-Minute Fire Doors: Standard Protection for Commercial Properties
For commercial fire doors or more risk-prone environments, a 60-minute fire door provides a solid level of protection. This rating is often required in places such as:
-
Offices: Where larger numbers of people work and where more time may be needed to evacuate.
-
Retail spaces: Particularly those with high foot traffic or storage areas containing flammable materials.
If you're looking for a door to protect valuable goods or assets, a commercial fire door installation with a 60-minute rating will give you the reassurance you need.
When You Need Higher Protection: 90-Minute and 3-Hour Fire Doors
90-Minute Fire Doors: Increased Protection for High-Risk Areas
A 90-minute fire door is commonly used in more hazardous areas. They are ideal for:
-
Areas with high fire loads: Such as kitchens, storage rooms, or places with significant electrical equipment.
-
Buildings with large open spaces: Where additional time is needed to evacuate or control the fire.
While 90-minute fire doors provide additional protection, they are still not as robust as 3-hour fire doors and are generally used in conjunction with other fire protection systems.
3-Hour Fire Doors: Maximum Protection for Critical Areas
For the highest level of fire protection, 3-hour fire doors offer unmatched performance. These doors are typically used in:
-
Fire separation walls: These walls divide large buildings into sections, slowing the spread of fire for hours.
-
Data centres: Where the cost of damage to equipment is very high.
-
Industrial sites: Where hazardous materials and machinery require the highest level of safety.
If you’re operating in an environment with substantial fire risks, it’s crucial to invest in bespoke fire doors with a 3-hour rating. These doors can mean the difference between catastrophic loss and minimal damage.

Choosing the Right Fire Door for Your Property
Commercial Fire Doors vs. Home Fire Doors
When selecting fire doors, it's important to consider whether the door is for a commercial or residential application.
-
Home fire doors: Typically, residential buildings require internal fire doors that offer protection for specific rooms, such as kitchens or garages. They are generally rated at 30 minutes or 60 minutes.
-
Commercial fire doors: Commercial buildings often need higher-rated doors, such as commercial external fire doors for flats or large office blocks, which can handle the intense demands of business operations.
Fire Door Range provides both bespoke fire doors and commercial fire door installations tailored to your specific needs.
External vs. Internal Fire Doors
There is a significant difference between internal fire doors and external fire doors for flats or other buildings.
-
Internal fire doors: These are typically used within the building to compartmentalise spaces and slow the spread of fire. They can be part of fire-rated partitions.
-
External fire doors for flats: These are designed to withstand extreme weather conditions while also offering robust fire protection. They are used in external walls of buildings, especially in flats or apartments.

The Role of Glass in Fire Doors
Many commercial fire doors are available with double fire doors with glass panels. This design is perfect for situations where visibility is required, such as:
-
Office buildings: Allowing people to see through doors for added security.
-
Retail spaces: Providing an open, welcoming environment while still offering fire protection.
However, it’s important to ensure the glass used in fire doors is fire-rated to prevent it from breaking or shattering during a fire.
