Fire safety requirements for industrial buildings differ from those for offices and residential properties in both scale and complexity. Industrial buildings typically involve larger fire compartments, heavier process loads, and more demanding operational conditions, which means the applicable classifications, compartmentation rules, and documentation requirements are more stringent. The sections below address the most common questions architects and specifiers encounter when working on industrial projects in the Netherlands and beyond.<\/p>\n
Fire resistance classifications for industrial buildings are expressed in terms of the door or partition’s ability to contain a fire for a defined period, measured in minutes. The two primary classification families relevant to industrial openings are EW<\/strong> and EI<\/strong>, each with a time suffix: for example, EW 60, EI1 60, or EI2 90. These classifications are defined under EN 13501-2, the European standard for fire resistance of construction products, including doors and shutters.<\/p>\n EW<\/strong> is the baseline criterion in the Dutch regulatory framework. A door classified as EW limits the transmission of flames and hot gases but permits limited radiant heat to pass through. EI<\/strong> classifications add a stricter insulation requirement on top of that: the unexposed face of the door must remain below a defined temperature threshold. EI1 and EI2 differ in how that temperature is measured, with EI2 representing the stricter criterion. Neither should be used interchangeably, and the correct classification for a given opening is always determined by the project-specific fire safety calculation, not by a blanket rule.<\/p>\n For industrial applications, the most commonly specified classes are EI1 60, EI2 60, and EI2 90, though projects with specific sector regulations, such as PGS15 for hazardous substances storage, may require higher ratings. Metacon-Next’s fire-rated industrial doors<\/a> are available in EI30, EI60, and EI90 classifications, covering the full range of typical industrial requirements.<\/p>\n The Dutch Building Decree (Besluit bouwwerken leefomgeving, or Bbl) establishes the minimum<\/em> fire safety requirements for new construction and significant renovation in the Netherlands. It sets baseline values for fire resistance duration and compartmentation, but it does not prescribe a single fixed classification per building type. The minimum requirements in the Bbl represent a floor, not a ceiling.<\/p>\n In practice, the actual requirements for a specific industrial project are often higher than the Bbl minimum. Three factors commonly push requirements upward:<\/p>\n Architects working on permit-ready designs need to account for all three layers, not just the Bbl baseline. The Bbl provides the legal minimum; the fire safety calculation provides the project-specific answer. For questions about how these layers interact for a specific project, contact Metacon-Next<\/a> for technical guidance.<\/p>\n Industrial buildings require higher fire ratings than offices because the fire load, compartment size, and operational conditions are fundamentally different. A production hall or logistics warehouse contains significantly more combustible material per square metre, and the people inside may be operating machinery or handling goods rather than sitting at desks, which affects both evacuation speed and fire development.<\/p>\n Several structural factors compound this:<\/p>\n These factors together mean that a fire-rated door specified for an industrial opening must not only carry the correct classification but also be built to withstand the physical demands of the environment.<\/p>\n A standard fire door is designed for pedestrian use in commercial or residential buildings: it is typically single-leaf, manually operated, and sized for a person walking through. A fire-rated industrial door is engineered for large, high-traffic openings in production and logistics environments, where the door may need to accommodate forklifts, automated guided vehicles, or wide goods flows while still meeting the same fire resistance classification requirements.<\/p>\n The distinction matters for specification because the performance criteria are the same – both must comply with EN 1634-1 and carry a CE marking – but the engineering challenges are different. Industrial fire doors must maintain their classification across much larger opening widths, withstand mechanical impact from vehicles, and in many cases operate automatically in response to a fire alarm signal. They may take the form of roller shutters, fire curtains, sliding doors, or sectional overhead doors rather than the hinged leaf format of a standard fire door.<\/p>\n Choosing the wrong product category for an industrial opening is a common specification error. A door that passes its fire resistance test in a standard configuration may not maintain that classification if it is installed in an oversized or mechanically demanding opening without the appropriate engineering. This is why working with a manufacturer that has in-house R&D and tests products across the full range of industrial configurations matters. Metacon-Next<\/a> designs and tests its industrial fire doors specifically for these demanding conditions.<\/p>\n The correct fire resistance class for an industrial opening is determined by a project-specific fire safety calculation, carried out by a qualified fire safety engineer. There is no universal table that maps building type to required classification. The calculation takes into account the fire compartment size, the occupancy type, the fire load, the evacuation scenario, and any applicable sector regulations.<\/p>\n As an architect, your role in this process is to define the opening dimensions and the performance criteria in the specification, then confirm that the product you select carries the required classification with independent test evidence. The steps in practice are:<\/p>\n If the fire safety calculation has not yet been completed at specification stage, specify the most likely classification based on the building type and flag it for confirmation. Do not assume that a lower classification will be acceptable without evidence from the calculation. You can request a quotation<\/a> from Metacon-Next once the classification is confirmed, including custom dimensions where standard products do not fit.<\/p>\n A fire-rated industrial door must come with a complete documentation package that allows you to demonstrate compliance at every stage of the project, from permit application through to building inspection and ongoing maintenance. Incomplete documentation is one of the most common causes of delays during fire safety reviews, and it is a risk that sits with the specifying architect if the product was not verified at specification stage.<\/p>\n The minimum documentation set for a compliant fire-rated industrial door includes:<\/p>\n Metacon-Next publishes its certificates, classification reports, and EPDs openly, without requiring a request or a signed NDA. This reflects a straightforward position: a specifier should be able to verify compliance before committing to a product, not after. If a supplier cannot provide the full documentation set at specification stage, that is a relevant factor in the selection decision.
