Amsterdam Building Decree 2012 Fire Resistance Requirements for Glazed Partitions
The Bouwbesluit 2012 sets out clear fire resistance requirements for glazed partitions based on building function, height, and fire compartment size. For Amsterdam’s typical residential and commercial projects, the following ratings are most commonly specified:
- EW 30: Required for many internal escape route partitions where limiting radiant heat is critical, but full insulation is not mandatory. This is common in low-rise office floors and residential corridors.
- EI 30: Mandated for fire compartments in buildings up to 13 meters high, ensuring both integrity and thermal insulation to prevent fire spread through conduction.
- EI 60: Typically required for compartment walls in high-rise buildings (over 13 meters) and for separating larger fire zones in commercial complexes, such as those found in Amsterdam’s Zuidas district.
Antifires systems, such as the 28mm EI60 panel (tested to 66 minutes integrity and 64 minutes insulation), are engineered to meet these exact thresholds. The glass composition—multi-layer tempered glass with intumescent gel—activates under heat to form a rigid insulating barrier. This prevents the temperature on the unexposed side from exceeding the standard limits (average rise ≤140°C, maximum ≤180°C). For Amsterdam’s historic canal houses, where retrofit work is common, the use of fire rated glass in slim-profile steel frames allows for integration without altering original sightlines, provided the assembly is tested as a complete system.
Selecting EI 30 and EI 60 Fire Rated Glass for Amsterdam’s Historic and Modern Architecture
Amsterdam’s unique blend of historic canal houses and contemporary high-rises presents distinct challenges for fire safety design. In historic structures, the primary goal is to enhance fire resistance while preserving the character-defining timber frames and slender glazing profiles. Antifires addresses this with 6mm E90 integrity-only glass and 10mm FPOS systems (integrity 135 minutes, insulation 16 minutes), which can be installed within existing rebates using ceramic wool (3–6mm, density 210 kg/m³) and intumescent seals to maintain the original aesthetic. For modern developments, such as the office towers in Sloterdijk or mixed-use projects in Overhoeks, local zoning plans often demand extended insulation performance (EI) to prevent smoke migration between floors. The 50mm/54mm EI120 ultra-high-performance glass (integrity and insulation up to 120 minutes) is ideal for these applications, providing a transparent barrier that meets the strictest compartmentation requirements. Key material specifications for these installations include:
| Component | Specification | Application |
| Frame | G.M.S. hollow steel sections | Structural support for all glazing types |
| Fire seal | Intumescent strip (20mm × 4mm) | Seals gaps at frame-to-glass junction |
| Insulation board | 12mm – 15mm fire-rated board | Behind frame for additional thermal barrier |
| Expansion gap | 3mm – 5mm filled with ceramic fiber | Accommodates thermal movement during fire |
These engineered details ensure that the entire assembly—glass, frame, and seals—functions as a certified system, critical for passing the Omgevingsdienst approval process.
Fire Rated Glass Applications in Amsterdam’s Office Towers, Hotels, and Canal-Side Renovations
In Amsterdam’s dynamic commercial sectors, fire rated glass is deployed in several critical applications. In the Zuidas and Sloterdijk office districts, open-plan layouts require atrium smoke barriers and floor-to-ceiling compartment walls that maintain visibility while preventing fire and smoke spread across large floor plates. Antifires’ 21mm FPOS glass (integrity 120 minutes, insulation 30 minutes) is frequently specified for these vision panels, offering a balance of transparency and thermal performance. For hotel corridors and lobby areas, where guest safety and aesthetic appeal are paramount, 26mm door glass (integrity 89–90 minutes, insulation 68 minutes) provides reliable protection for escape routes. In canal-side renovations, where historic buildings are converted into boutique hotels or residential units, fire rated glass is used in internal partitions to create modern fire compartments without altering the external facade. The fire rated glass systems must be installed with M6/M8 anchor bolts at 300–600mm spacing and proper expansion gaps (3–5mm filled with ceramic fiber) to ensure the assembly performs as tested. Common project scenarios include:
- Office towers: EI 60 glazed partitions for core walls and stairwell enclosures.
- Hotels: EI 30 or EI 60 vision panels in guest room doors and corridor partitions.
- Retail units: EW 30 glazed shop fronts with fire-rated backing to compartmentalize from public areas.
Each application requires a system-level certification that includes the frame, glass, and seals—a standard Antifires meets with documented test data under EN 1634-1.
Why Amsterdam Architects and Contractors Trust Antifires for Fire Rated Glazing
Amsterdam architects and contractors choose Antifires for several verifiable reasons rooted in technical compliance and project support. First, all Antifires products carry EN 1634-1 and EN 16034 certifications, which are directly referenced by the Dutch Bouwbesluit 2012 for CE marking. This eliminates ambiguity during building permit applications. Second, the company provides localized technical support tailored to Amsterdam’s regulatory environment, including CAD drawings that detail frame profiles, fixing schedules, and sealant specifications. This documentation helps streamline approvals from the Omgevingsdienst. Third, Antifires offers on-site installation guidance for complex retrofits, such as integrating fire rated glass into historic canal house frames. The use of ceramic tape (3mm–6mm) and intumescent fire seals (20mm × 4mm) ensures that the assembly’s fire performance is not compromised by site conditions. For projects requiring the highest performance, the 50mm/54mm EI120 system provides verified integrity and insulation for up to 120 minutes, suitable for the most demanding compartmentation requirements. By combining certified test data with practical application expertise, Antifires reduces the risk of costly delays and ensures that Amsterdam’s built environment meets the highest standards of passive fire protection.
