Learn about fire door specifications and ratings, including 30, 60, 90 & 120-minute fire doors, frames, hardware, glazing and testing with THE INGRESS.

A fire door is more than a metal or wooden door. Its fire performance depends on the complete tested door assembly, which can include the door leaf, frame, hardware, seals, glazing, closing mechanism, and installation details. The required specification should be determined by the project's approved fire and life-safety design and applicable codes.

What Is a Fire-Rated Door?

A fire-rated door is a door assembly designed and tested to resist fire for a specified period under defined test conditions. Its purpose is generally to help maintain fire compartmentation and restrict the spread of fire through protected openings.

A complete fire door assembly may include the door leaf, frame, hinges, door closer, latch or lock, intumescent or smoke seals where required, compatible glazing, panic hardware where applicable, and other tested components.

Simply using a steel door does not automatically make it a fire-rated door.

Understanding Fire Door Ratings

Fire door ratings are commonly expressed in minutes. Depending on the applicable standard, building design, and tested product configuration, projects may specify ratings such as:

A higher numerical rating should not automatically be selected for every opening. The required rating depends on the fire strategy, wall or partition rating, occupancy, opening location, and applicable regulatory requirements.

THE INGRESS can be contacted to discuss available fire door ratings and configurations for specific projects.

Important Fire Door Specifications

When selecting a fire door, buyers and project consultants should review more than the fire-rating duration.

1. Door Material

Fire-rated doors can be manufactured using different construction systems, including steel and timber-based assemblies.

The material alone does not establish the rating. The complete construction must correspond with the tested or assessed configuration.

2. Door Leaf Construction

Important parameters can include leaf thickness, internal construction, edge details, reinforcement, and other design characteristics.

These specifications vary according to the manufacturer's tested system.

3. Fire Door Frame

The frame is an integral part of the assembly.

Frame profile, material, dimensions, anchors, clearances, and installation method should comply with the approved configuration.

4. Single-Leaf & Double-Leaf Fire Doors

Fire doors may be available as:

• Single-leaf fire doors
• Double-leaf fire doors

Double-leaf assemblies require particular attention to meeting stiles, sequencing, latching, seals, and hardware where applicable.

5. Fire-Rated Vision Panel

Some fire doors can incorporate a glazed vision panel.

The glass cannot simply be ordinary architectural glass. The glazing type, dimensions, fixing system, and location must be appropriate for the tested fire door assembly.

6. Intumescent Seals

Intumescent materials are designed to expand when exposed to elevated temperatures and may form part of a tested fire door system.

Their dimensions and positioning should follow the applicable door specification.

7. Smoke Seals

Where smoke-control performance is required, suitable seals and an appropriately tested/classified assembly may be necessary.

A fire-resistance rating alone should not automatically be interpreted as a smoke-leakage rating.

8. Fire Door Hardware

Hardware can influence the performance of a fire door.

Depending on the assembly and application, hardware may include hinges, door closers, locks, latches, panic exit devices, coordinators, flush bolts, and other components.

Only hardware compatible with the specified fire door system should be used.

Fire Door Testing & Certification

One of the most important factors when procuring a fire door is the supporting test and certification documentation.

Depending on the project and jurisdiction, different standards or certification schemes may apply. Buyers should request documentation relevant to the exact product being proposed rather than relying only on marketing terms such as “fireproof door.”

Before approval, verify:

• Applicable fire-test standard
• Test report or certification details
• Tested fire-resistance duration
• Door construction covered by the report
• Maximum/minimum permitted dimensions
• Single/double-leaf applicability
• Frame construction
• Glazing limitations
• Hardware requirements
• Installation details
• Any field of application or permitted variations

THE INGRESS can provide information about documentation applicable to its available fire door systems. Exact certifications should be verified against current product documents.
