Before a building permit is issued in the Netherlands, the competent authority checks whether the design meets the fire safety requirements set out in the Besluit bouwwerken leefomgeving (BBL) — the Dutch Building Decree. This means verifying that the building’s compartmentation layout, fire resistance classifications, and product certifications are all documented and demonstrably compliant. The sections below answer the specific questions architects and specifiers most often face when preparing a permit-ready fire safety file.
What documents does a fire safety review examine at permit stage?
A fire safety review at permit stage examines the fire safety drawings, the fire compartmentation plan, the fire resistance classifications specified for each separation, and the product documentation proving those classifications can actually be achieved. Without complete, consistent documentation across all of these, a permit application is likely to receive objections or be returned for revision.
In practice, the reviewing authority checks whether the design drawings clearly identify each fire compartment boundary, label the required fire resistance duration, and reference the products or constructions that will deliver that resistance. For fire-rated doors and closures specifically, this means the application file needs to include CE declarations of performance, classification reports from an accredited test body, and any product-specific technical data sheets.
Architects who specify products before full documentation is available risk delays at the permit stage. The most defensible approach is to select products whose complete technical file — including classification reports and environmental product declarations — is available at the specification stage rather than after order placement. Metacon-Next’s fire-rated door range is supplied with full documentation, including CE declarations, Efectis classification reports, and EPDs, making it straightforward to close a permit file without chasing the manufacturer for missing certificates.
What fire resistance classifications are relevant under the Dutch Building Decree (BBL)?
Under the BBL, fire resistance for separating constructions is expressed using the European classification system defined in EN 13501-2. The classifications most relevant to industrial doors and closures are EW (integrity and radiation reduction — the Dutch standard baseline criterion), EI1 (integrity and insulation, stricter temperature rise criterion), and EI2 (integrity and insulation, less strict temperature rise criterion). The BBL sets only the absolute minimum requirement; project-specific fire safety calculations, sector regulations, or client and insurer requirements can raise those minimums above the baseline.
What does EW mean for a fire door?
EW is the Dutch standard baseline criterion. A door classified EW provides integrity — it prevents flames and hot gases from passing through — and limits radiant heat transfer through the door. It does not provide full thermal insulation. EW is not simply “heat is limited”: it is the Dutch standard baseline classification under EN 13501-2, meaning the door meets the minimum radiation reduction criterion required in the Netherlands. However, people or materials on the non-fire side may still be exposed to significant heat over extended periods, which is why heavier classifications may be required depending on the specific fire safety calculation for a project.
What is the difference between EI1 and EI2?
Both EI1 and EI2 add a thermal insulation criterion on top of integrity. The distinction lies in strictness: EI1 applies a stricter temperature rise limit on the unexposed face of the door, meaning the cold side stays cooler for longer. EI2 permits a higher temperature rise on the unexposed side and is therefore the less strict of the two insulation criteria. Never use “EI” without specifying which variant applies — EI1 and EI2 represent meaningfully different performance levels and are not interchangeable in a specification.
The required classification for any specific opening is determined by the project’s fire safety calculation, not by a blanket rule tied to building type. The BBL sets only the absolute minimum; sector regulations such as PGS 15 for hazardous substances storage, insurer requirements, or the client’s programme of requirements can all impose higher classifications than that minimum. Architects should confirm the applicable requirements with the fire safety engineer before finalising the specification.
How does compartmentation affect permit approval for industrial buildings?
Compartmentation is one of the primary fire safety requirements for industrial buildings, and it directly affects whether a permit is approved. The BBL requires large buildings to be divided into fire compartments of a maximum size, limiting the area over which a fire can spread uncontrolled. If the compartmentation layout in the submitted drawings does not comply with those size limits, or if the separating constructions are not specified with the correct fire resistance classification, the permit will not be granted without revision.
For logistics centres, production halls, and warehouses, compartmentation presents a practical challenge: the operational logic of the building — large open floor plates, forklift routes, and continuous material flow — often conflicts with the need to insert fire-resistant barriers. The solution is not to eliminate compartment boundaries but to specify fire-rated closures that maintain the required separation while allowing operational continuity. Fire-rated roller doors, sliding doors, and automatic fire doors can all be integrated into a compartment boundary without permanently blocking internal transport routes.
When a building changes use — for example when a warehouse is converted to a production facility or a logistics function changes intensity — the compartmentation requirements may change as well. A change of use that triggers a new fire safety calculation can require retrofitting additional compartment boundaries or upgrading existing closures to a higher fire resistance classification. The specific classification required depends on that project-specific calculation, and a qualified fire safety engineer or the local authority should be consulted to determine the applicable requirement. This is a common source of permit complications in renovation projects and should be assessed at the earliest design stage.
Which product certifications satisfy fire safety requirements at permit stage?
For fire-rated doors and closures in the Netherlands, the certifications that satisfy fire safety requirements at permit stage are CE marking under the Construction Products Regulation (CPR), supported by a declaration of performance and an independent classification report in accordance with EN 13501-2. The classification report must come from an accredited test body; Efectis is a recognised body for this purpose. Products that carry CE marking but cannot provide an underlying classification report from an accredited laboratory do not meet the evidentiary standard for permit submission.
It is also worth noting that for industrial fire doors, CE marking obligations arise from two standards simultaneously: EN 16034, which covers fire- and smoke-resisting closing elements, and EN 13241, which applies to industrial doors generally regardless of fire rating. Both are relevant and should not be treated as interchangeable or as alternatives to one another.
Beyond the classification report and CE declaration, architects increasingly need environmental product declarations for BREEAM- and LEED-rated projects. An EPD is an information document, not an environmental award or sustainability label, but it provides the verified lifecycle data that green building assessment schemes require. Specifying products that already carry EPDs avoids a separate documentation request later in the project.
ISO 9001 and ISO 14001 certification of the manufacturer provides additional assurance that the production process is controlled and audited, but these management system certificates do not substitute for product-level fire resistance classification. Both types of certification serve different purposes, and both are relevant to a complete specification file. Metacon-Next holds ISO 9001 and ISO 14001 certification, renewed in April 2025, alongside CE certification and Efectis classification reports for its fire-rated product range.
What causes fire safety objections during the permit review process?
The most common causes of fire safety objections during permit review are incomplete product documentation, inconsistencies between the compartmentation plan and the fire resistance classifications specified, and missing or incorrect CE declarations. Reviewers compare what the drawings show against what the product documentation proves, and any gap between the two results in a formal objection that must be resolved before the permit can proceed.
Specific issues that repeatedly cause delays include:
- Specifying a fire resistance classification without providing the classification report that demonstrates the product achieves it
- Writing “EI” without specifying EI1 or EI2, which leaves the classification ambiguous and unverifiable
- Compartment boundaries shown on drawings that are not carried through consistently to all openings, including service penetrations and ventilation ducts
- Products listed in the specification that carry CE marking for a different performance characteristic than the one required
- EPDs missing from the file when the project is subject to a green building assessment scheme
The most effective way to avoid objections is to build the specification around products whose complete technical file is publicly available and consistent. When a manufacturer publishes all classification reports, CE declarations, and EPDs openly, the architect can verify compliance at the specification stage rather than discovering a gap during permit review. Metacon-Next publishes its full technical documentation openly, including Efectis classification reports and EPDs, so specifiers can confirm the relevant details without waiting for information to be supplied on request.
For architects working on industrial construction or renovation projects where fire safety documentation needs to be watertight from the outset, contacting Metacon-Next directly or requesting a quotation provides access to the full technical file alongside the product range, supporting a permit application that is complete on first submission.
