Yes, it is possible to combine high-speed operation with fire resistance in a single door. High-speed fire doors are purpose-built products that operate at elevated speeds under normal conditions and automatically close to form a certified fire-resistant barrier when an alarm is triggered. They are not a compromise between two conflicting requirements — they are a distinct product category designed to meet both simultaneously. The sections below address the most common questions architects and specifiers raise when evaluating high-speed fire doors for industrial applications.
What makes a door both high-speed and fire-resistant?
A high-speed fire door achieves both functions through a combination of fire-rated materials and a drive mechanism engineered to operate at speeds that standard fire doors cannot reach. Under normal conditions, the door opens and closes rapidly to support internal traffic flow. In a fire scenario, the drive system disengages or overrides, and the door closes fully to form a certified fire-resistant barrier in accordance with EN 1634-1.
The key design challenge is that conventional high-speed doors use flexible curtains or lightweight materials optimised for speed, not thermal resistance. A high-speed fire door replaces those materials with fire-rated panels, seals, and frame assemblies that have been independently tested to withstand heat and flames for a defined period. The drive system must also be fail-safe: if power is lost or a fire signal is received, the door closes automatically without requiring manual intervention.
This combination demands rigorous engineering. The door must be fast enough to serve logistics or production environments without creating bottlenecks, and robust enough to pass standardised fire resistance testing. These two demands are reconciled through product-specific design, which is why high-speed fire doors are tested and classified as complete assemblies, not as individual components.
How do high-speed fire doors work in a fire?
When a fire is detected, a high-speed fire door receives a signal from the building’s fire alarm system and immediately initiates an automatic closing sequence. The drive mechanism releases or reverses, and the door descends or closes under gravity or spring tension to reach the fully closed position. Once closed, the fire-rated assembly provides resistance to flames, heat, and smoke for the duration of its classification.
Most high-speed fire doors are connected to the building’s fire detection network via a control unit that continuously monitors alarm signals. Some systems also incorporate local heat or smoke detectors at the door opening itself, providing a secondary trigger if the central alarm has not yet activated. Once the door has closed in response to an alarm, it remains closed until the alarm is reset by an authorised person — it does not reopen automatically.
The closing mechanism is typically gravity-assisted or spring-loaded to ensure closure even in the event of a power failure. This is a functional safety requirement: a fire door that depends on an active power supply to close is not considered reliable under fire conditions. The fail-safe behaviour of the closing system is verified as part of the product’s type testing and must be demonstrated before a CE marking can be issued.
What fire resistance classification can high-speed doors achieve?
High-speed fire doors are typically available in classifications ranging from EW 30 to EI2 60, depending on the product design and the results of independent type testing. The achievable classification depends on the specific product, its construction, and the test results documented in the classification report. Not all high-speed door products reach the same classification, and architects should verify the exact classification against the project’s fire safety requirements.
It is important to distinguish between classification types. EW classifications limit the passage of flames and hot gases, and restrict radiated heat to a defined threshold. EI1 and EI2 classifications additionally limit the temperature rise on the unexposed face of the door, with EI2 applying a stricter insulation criterion than EI1. A project’s fire safety calculation determines which classification is required for a given opening — no single classification is universally correct for all industrial applications.
In practice, many high-speed fire doors on the market are classified at EW 30 or EI2 30. Products achieving EI2 60 exist but are less common, and the construction requirements to reach that classification typically result in a heavier, more complex door. Architects specifying high-speed fire doors should request the full classification report — not just the classification code — to confirm the test conditions match the intended installation.
Metacon-Next manufactures fire-rated industrial doors across multiple product types, with classifications documented in publicly available classification reports and CE declarations. This level of documentation transparency is directly relevant when specifying products for permit-ready designs.
Where are high-speed fire doors typically installed?
High-speed fire doors are most commonly installed in openings where internal traffic is frequent and fire compartmentation is simultaneously required. Typical locations include logistics centres with intensive forklift movement between compartments, production halls where automated guided vehicles or conveyor systems cross compartment boundaries, and cold storage facilities where rapid door cycling is operationally necessary.
In these environments, a standard self-closing fire door creates an operational problem: it closes after every passage, slowing throughput and increasing wear. A high-speed fire door remains open or cycles rapidly during normal operations, then closes automatically when an alarm is triggered. This makes it suitable for openings that would otherwise represent a conflict between fire safety requirements and operational efficiency.
Other common installation locations include:
- Transition zones between production and warehouse areas in manufacturing facilities
- Loading dock connections to temperature-controlled storage zones
- Internal corridors in healthcare complexes handling large equipment or supply trolleys
- Openings in large commercial buildings where compartmentation is required but access frequency is high
The Metacon-Next product range covers several of these application types, with products designed for the dimensional and operational demands of industrial openings. Custom dimensions are available for openings that fall outside standard product ranges.
What certifications should a high-speed fire door have?
A high-speed fire door intended for use in the European market must carry a CE marking based on testing in accordance with EN 1634-1, the European standard for fire resistance and smoke control tests for door assemblies. The CE marking must be accompanied by a Declaration of Performance specifying the classification achieved, and a classification report from an accredited testing body documenting the test conditions and results.
Beyond CE marking, architects and specifiers should verify the following documentation before specifying a product:
- Classification report: The full test report from an accredited laboratory, confirming the classification under the conditions tested. This is distinct from a certificate summary and should be available on request or publicly accessible.
- Declaration of Performance (DoP): The manufacturer’s formal declaration of the product’s performance characteristics, required for CE marking under the Construction Products Regulation.
- Environmental Product Declaration (EPD): Increasingly required for BREEAM and LEED projects, an EPD documents the environmental impact of the product across its lifecycle. It is an information document, not an environmental award.
- Maintenance documentation: Fire doors are subject to periodic inspection requirements. The manufacturer should provide a maintenance schedule and documentation confirming the door’s performance is maintained over time.
Some countries apply additional national requirements beyond CE marking. Germany, France, Switzerland, and Austria, for example, have supplementary certification requirements that a CE-marked product does not automatically satisfy. Architects working on cross-border projects should confirm whether country-specific approvals are needed for the intended installation location. Metacon-Next has conducted additional testing for several of these markets — details are available through the Metacon-Next contact page or via the dealer network.
Independent testing by a recognised body such as Efectis adds a further layer of credibility. Products tested by an accredited third party provide stronger documentation support during permitting and fire safety reviews than products relying solely on manufacturer declarations.
What’s the difference between a high-speed fire door and a fire shutter?
A high-speed fire door and a fire shutter are both automatic fire-resistant closures, but they differ in construction, operation, and typical application. A fire shutter is a passive device that remains open under normal conditions and closes only when triggered by a fire alarm or heat detector, typically descending by gravity. A high-speed fire door actively cycles open and closed during normal operations at elevated speed, and closes automatically under fire conditions.
The practical distinction matters for specification. A fire shutter is designed for openings that do not require frequent passage during normal operations — it is essentially a dormant barrier that activates in an emergency. A high-speed fire door is designed for openings with continuous or frequent traffic, where the door must function as an operational element as well as a fire safety component.
From a structural standpoint, fire shutters are often used for larger openings, such as wide vehicle access points or openings between large production areas, where the scale of the opening makes a conventional door impractical. High-speed fire doors are more commonly used for openings in the range of standard to moderately large industrial dimensions, where the door’s operational cycling is a design requirement.
Both product types must carry appropriate CE markings and classification documentation. The classification criteria — EW or EI, and the duration in minutes — apply equally to both, and the selection between them should be driven by the operational requirements of the opening, not by a preference for one product type over another. Architects can review the full range of certified fire-rated door solutions available from Metacon-Next to compare product types across applications.
When evaluating either product type, the same documentation standards apply: classification report, Declaration of Performance, and EPD where required. A supplier that makes this documentation publicly available without requiring a formal request removes a significant friction point from the specification process. Metacon-Next publishes its certificates and classification reports openly — a practical advantage when closing a design file under time pressure.
