60-Minute vs 120-Minute Fire Rated Doors: Understanding the Key Differences
Fire safety is an essential consideration in the planning and construction of commercial, industrial and institutional buildings. From factories and office complexes to hospitals and shopping centers, selecting appropriate fire protection systems helps improve building safety.
Among these systems, fire rated doors play an important role in passive fire protection. They are designed to provide resistance against fire for a specified duration when installed as part of an approved and tested assembly.
Two commonly specified fire resistance durations are 60 minutes and 120 minutes. But what is the difference between these two options, and how can building owners select the right one?
Let's understand their features, applications and important selection factors.

What Are Fire Rated Doors?
Fire rated doors are specially designed door assemblies that undergo testing to evaluate their ability to resist fire under specified conditions.
Unlike conventional doors, these systems are designed to maintain a fire-resistant barrier for a defined period. Their performance depends on several elements, including the door leaf, frame, hardware, seals and installation arrangement.
Fire rated doors are commonly considered for buildings where fire compartmentation and protection of designated areas are important.
What Is a 60-Minute Fire Rated Door?
A 60-minute fire rated door is a door assembly designed and tested to provide the specified fire resistance performance for up to 60 minutes under the applicable test conditions.
These configurations may be considered for selected commercial, institutional and industrial applications, depending on the building's fire safety design.
Common considerations include:
Suitable tested door and frame configuration.
Compatible hinges, locks and latching hardware.
Appropriate intumescent sealing arrangements.
Correct installation according to approved specifications.
Supporting fire test documentation.
The actual suitability of a 60-minute fire door depends on the project's requirements and applicable regulations.
What Is a 120-Minute Fire Rated Door?
A 120-minute fire rated door is designed and tested for a specified fire resistance duration of up to 120 minutes under the applicable testing conditions.
These configurations may be specified in buildings or locations where a longer fire resistance duration is required by the approved fire safety strategy.
Important considerations include:
Tested door leaf and frame assembly.
Compatible fire-rated hardware.
Suitable sealing arrangements.
Installation in accordance with approved requirements.
Relevant testing and certification documents.
A higher fire resistance duration should not automatically be considered suitable for every location. The required rating must be determined through the building's fire safety design.
60-Minute vs 120-Minute Fire Rated Doors: Key Differences
60-Minute Fire Rated Door
Fire resistance duration: 60 minutes
Testing: Applicable 60-minute fire resistance testing
Selection: Based on building safety requirements
Components: Approved tested door assembly
Documentation: Relevant fire test reports
120-Minute Fire Rated Door
Fire resistance duration: 120 minutes
Testing: Applicable 120-minute fire resistance testing
Selection: Based on building safety requirements
Components: Approved tested door assembly
Documentation: Relevant fire test reports
The main difference between these two fire door configurations is their specified fire resistance duration. The final selection should always follow the building's fire safety design and applicable regulations.
Which Type of Fire Rated Door Is Right for Your Building?
Choosing between 60-minute and 120-minute fire rated doors requires an understanding of the building's design and fire protection requirements.
Consider the following factors:
1. Building Type and Occupancy: Different buildings have different occupancy patterns and safety requirements. Hospitals, industrial plants, commercial complexes and educational institutions may require different fire door specifications.
2. Fire Compartmentation Requirements: The building's fire safety plan determines where fire-resistant barriers and doors are required. The specified fire rating should match the approved design.
3. Door Location: The location of a door can influence its required fire resistance duration. Doors protecting designated escape routes, service areas or compartment boundaries may have different specifications.
4. Product Testing and Certification: Always verify that the manufacturer's fire test documentation covers the actual door configuration, including the frame and relevant hardware.
5. Installation and Maintenance: Even a tested fire door may not perform as intended if it is incorrectly installed, fitted with unsuitable components or poorly maintained.
Different Types of Fire Rated Doors Available
Fire rated doors are available in different materials and configurations to suit architectural and functional requirements.
1. Metal Fire Doors: Metal fire doors are commonly considered for factories, warehouses, commercial properties and industrial facilities. They provide a robust construction option for projects requiring documented fire resistance.
2. Wooden Fire Doors: Wooden fire doors can be suitable for selected offices, hotels and institutional interiors where appearance is an important consideration.
3. Glazed Fire Doors: Glazed fire doors are used in selected commercial environments where visibility and natural light are desirable alongside specified fire protection performance.
Each type must have suitable testing documentation for its intended fire rating and configuration.
