Bilbao Fire Rated Glass Certified for CTE DB-SI and EN 13501 Compliance

Bilbao’s construction sector, from the revitalized Zorrotzaurre peninsula to the commercial corridors of Abando, operates under the stringent fire safety framework of Spain’s Código Técnico de la Edificación (CTE), specifically the Documento Básico de Seguridad en caso de Incendio (DB-SI). This national standard mandates that all glazed elements used for building compartmentation, escape route protection, and fire-resisting enclosures must achieve verified performance classifications. Antifires supplies certified fire rated glass and door systems that are fully tested to European standards, including EN 13501-2 and EN 1634-1, ensuring seamless alignment with CTE DB-SI requirements. For specifiers in Bilbao, compliance begins with selecting products that carry CE marking under the Construction Products Regulation (CPR) and demonstrate proven EI (Integrity and Insulation) ratings. The CTE DB-SI, accessible via the official Spanish Ministry of Transport, Mobility and Urban Agenda official CTE website, provides the baseline for fire resistance in terms of minutes (30, 60, 90, 120) and reaction-to-fire classes (A1, A2, B-s1, d0). Antifires’ technical documentation, available in both Spanish and Basque, directly supports permit submissions by local architects and building control officers, reducing approval timelines for Bilbao’s diverse projects.

Adapting to Bilbao’s CTE DB-SI Fire Safety Requirements for Building Compartmentation

Bilbao’s building projects, whether new commercial towers or refurbished public facilities, must strictly adhere to the CTE DB-SI sections on compartmentation and evacuation. This regulation defines fire resistance requirements based on building use, height, and occupancy load. For example, a glazed partition separating two fire compartments in a Bilbao office building typically demands an EI 60 classification, meaning the system must prevent flame penetration (Integrity) and limit heat transfer (Insulation) for 60 minutes. Antifires provides 60 minute fire rated glass systems that meet these exact criteria, tested under BS EN 1364-1 for non-loadbearing walls and EN 1634-1 for door assemblies. The localized approach involves analyzing the building’s sectorization plan and evacuation route design, ensuring that each glazed element—from lobby screens to corridor doors—achieves the required EI rating without compromising architectural transparency. Antifires’ technical team in the Basque Country can provide pre-compliance calculations and system specifications that directly reference CTE DB-SI tables, facilitating faster approval from Bilbao’s municipal building departments.

Selecting EI 30 to EI 120 Fire Rated Glass for Bilbao’s Coastal Humidity Conditions

Bilbao’s coastal location, with its high relative humidity and temperature fluctuations, presents unique challenges for fire-rated glazing systems. The CTE DB-SI requires that all fire-resisting elements maintain their performance over the building’s lifespan, which is particularly critical for glazed assemblies exposed to moisture ingress. Antifires offers a range of EI 30, EI 60, and EI 120 fire-rated glass units specifically designed to resist delamination and seal degradation in such environments. These systems utilize multi-layer tempered glass with intumescent interlayers, such as the 28mm EI60 panel (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) and the 50mm EI120 ultra-high-performance glass, which are tested under ambient conditions of 27°C–36°C and humidity up to 90%. For Bilbao’s mixed-use developments in areas like Deusto and Indautxu, where high-traffic commercial zones require both fire safety and thermal comfort, Antifires provides solutions that also meet the reaction-to-fire class A2-s1, d0 as per EN 13501-1. This ensures that the glass contributes minimally to fire spread while maintaining insulation performance. All systems are supplied with ceramic wool (density 210 kg/m³) and intumescent fire seals (20mm × 4mm) to guarantee a robust, moisture-resistant perimeter seal.

Addressing Fire Protection Needs in Bilbao’s Historic Renovations and Industrial Estates

Bilbao’s urban fabric includes historic buildings in the Casco Viejo and large-scale industrial estates in the Port of Bilbao and Zorrotzaurre. These projects often require fire-rated glazing that integrates with existing steel or concrete structures without extensive modification. Antifires’ systems are designed for both new builds and retrofits, using G.M.S. hollow steel frames and fire-rated insulation boards (12mm–15mm) that can be adapted to non-standard openings. For the Zorrotzaurre regeneration zone, where former industrial warehouses are being converted into mixed-use spaces, the demand is for EI 60 to EI 120 glazed partitions that provide compartmentation while preserving the open-plan aesthetic. In the Port of Bilbao’s logistics zones, factory partition walls and warehouse doors require integrity-only (E) ratings up to 120 minutes to contain potential fire loads. Antifires supplies 90 minute fire rated glass and 120 minute fire rated glass systems that are fully tested to BS 476 Part 22 and AS1530.4, ensuring compatibility with both European and international standards. The installation process uses M6/M8 anchor bolts at 300–600mm spacing and 3mm–5mm expansion gaps filled with ceramic fiber, accommodating structural movement while maintaining fire integrity.

Why Bilbao Specifiers Choose Antifires for Certified Fire Rated Glass and Doors

Bilbao specifiers—including architects, fire consultants, and main contractors—choose Antifires for a combination of technical reliability and localized service. All products carry CE marking under EN 16034 and are tested to EN 1634-1 and BS EN 1364-1, providing auditable certification for every project.

Frequently Asked Questions (FAQ)

For a commercial building in Bilbao, the CTE DB-SI requires fire-rated glass to meet specific EI (Integrity and Insulation) classifications based on the building’s use and compartment size. Typically, glazed partitions separating fire compartments must achieve EI 60 (60 minutes) for most commercial applications, while escape route enclosures may require EI 30 or EI 60 depending on travel distance and building height. The glass must also comply with reaction-to-fire class A2-s1, d0 as per EN 13501-1, meaning it does not contribute to fire spread. Antifires provides certified systems that meet these classifications, with test reports aligned to EN 1634-1 and EN 1364-1, ensuring full compliance with Bilbao’s local building permit requirements.

Yes, Antifires supplies fire-rated glass with both integrity (E) and insulation (I) ratings, specifically designed for Bilbao’s coastal climate. These systems, such as the 28mm EI60 panel and 50mm EI120 units, use multi-layer tempered glass with intumescent interlayers that resist moisture-induced delamination. They are tested under high-humidity conditions (up to 90% relative humidity) and maintain their performance over time. The ceramic wool and intumescent seals used in the perimeter frames provide additional protection against moisture ingress. All products carry CE marking and are compliant with EN 13501-2, making them suitable for Bilbao’s mixed-use developments in areas like Abando and Deusto.
