How to Select the Right Fire Door for Your Building
When it comes to protecting lives and property during a fire, one decision that shouldn’t be taken lightly is choosing the right fire door for your building. Selecting the right fire rated door is essential for protecting lives and ensuring compliance with fire safety regulations. To make an informed choice, you must consider fire door ratings, the door’s materials and design, compliance standards, installation practices, maintenance needs, and more. Whether you’re a property owner, facility manager, or contractor, understanding the different types of fire doors and where to use them is crucial for safety and legal compliance.

Understanding Fire Door Ratings
Fire door ratings indicate how long a door can withstand exposure to fire and smoke, typically ranging from 20 to 90 minutes. These ratings are established through standardized testing in certified labs and are crucial for compliance with local and national building codes.
Common Fire Door Ratings:
20-minute rating: Ideal for low-risk areas.
45-minute rating: Suitable for stairwells and corridors.
60-minute rating: Used in higher-risk zones or between compartments.
90-minute rating: Required in high-risk zones needing maximum protection.
Evaluating Building Type and Usage
Understanding the specific needs of your building is the foundation of choosing the right fire rated door.
Hospitals & Schools: Require high-rated fire doors to protect vulnerable individuals.
Hotels & Residential Complexes: Need doors that balance safety and aesthetic appeal.
Factories & Warehouses: Benefit from industrial-grade fire shutters or steel doors for robust protection.
Choosing the Right Materials
The choice of materials affects both the door’s durability and aesthetics. Some common options include:
Steel: Strong, durable, and ideal for industrial applications.
Timber: Provides a traditional aesthetic; available with fire-resistant cores.
Glass Panels: Suitable for visibility while maintaining compliance (fire-rated glass only).
Balance durability and cost: Steel may offer better long-term performance, while timber may better suit commercial interiors.
Fire Door Certification and Regulations
Before choosing the right fire door, ensure it’s certified — indicating how long it can resist fire (e.g., FD30, FD60, or FD240).
Regulatory compliance is mandatory, and fire doors must align with:
Approved Document B (new builds or extensions)
Regulatory Reform (Fire Safety) Order: 2005 (RRO) (existing buildings)
Ignoring these regulations can result in legal penalties, fines, and increased risk during emergencies.
Fire-Rated Ironmongery:
Hinges, locks, closers, and panic bars must be certified fire-rated too.
Installing uncertified hardware can void certification.
Types of Fire Doors to Consider
Choosing the right fire door means evaluating your building’s layout, use, and the potential fire risks within it. Here are the main types you should know about:
I. Internal Fire Doors
These are designed to compartmentalise fire within sections of a building. Commonly used in hallways, communal spaces, or between rooms, internal fire doors must:
Be self-closing
Remain shut at all times (never propped open)
Match your interior aesthetic without compromising safety
Fire-rated options like FD30 (30-minute protection) or FD60 (60-minute protection) are standard for internal use.
II. External Fire Doors
External fire doors are typically used as part of fire exits. Often made with reinforced glass and self-closing mechanisms, these doors:
Provide safe building egress
Withstand exposure to weather and external threats
Must remain unlocked or be fitted with "push bar" systems for quick escape
They are ideal for commercial buildings where emergency exits are critical.
III. Communal Fire Doors and Screens
In multi-occupancy structures such as flats, hotels, schools, or nursing homes, communal fire doors:
Break up long corridors to limit fire spread
Are usually double doors with glass panels for visibility
Can be automated to close during a fire alarm
These are essential for safe evacuation in densely occupied environments.
IV. Steel Reinforced Fire Doors
If your property stores valuable inventory, uses high-powered equipment, or is in a high-crime area, steel fire doors offer unmatched security and fire protection. Key features include:
Resistance to wear and extreme weather
Hygiene suitability for medical and food-grade environments
Extended fire resistance — up to 3–4 hours (FD240 rating)
Despite their heavy-duty nature, many steel doors are available in attractive finishes like woodgrain or PVC.
Considering Aesthetic Requirements
Fire doors should complement your building’s design without compromising safety. Today, many manufacturers offer doors in a variety of finishes including wood grain, metal, or glass to match your aesthetic preferences.
After-Sales Support & Warranty
While selecting supplier ask about:
Warranty period (usually 1–5 years)
Spare part availability
Maintenance/repair services: Crucial for schools, hospitals, or multi-building facilities.
