Murcia Fire Rated Glass Certified for CTE DB-SI and EN 1364 Compliance

In the evolving landscape of building safety within the Region of Murcia, compliance with the Spanish Código Técnico de la Edificación (CTE), specifically Documento Básico de Seguridad en Caso de Incendio (DB-SI), is non-negotiable. For architects, contractors, and facility managers operating in cities like Murcia, Cartagena, and Lorca, selecting certified fire rated glass is critical to meeting compartmentation and evacuation requirements. Antifires provides fully tested glazing systems that align with both the CTE DB-SI and European standards (EN 1364, EN 1634), ensuring that projects—from historic Casco Antiguo renovations to modern Polígono Industrial developments—achieve the required fire resistance levels without compromising design integrity. The CTE DB-SI mandates specific EI (Integrity and Insulation) ratings for elements such as stairwell enclosures and facades, often requiring EI 60 or EI 120 performance. Antifires’ product range, including 28mm EI60 and 50mm EI120 systems, has been verified under rigorous furnace conditions (BS EN 1364-1 and BS EN 1634-1) to deliver these exact classifications. For localized regulatory guidance, professionals can reference the official CTE documentation on the Spanish Ministry of Transport, Mobility and Urban Agenda website. By integrating third-party certified data with localized application knowledge, Antifires ensures that Murcia’s buildings achieve both aesthetic continuity and uncompromised passive fire protection.

Spanish CTE DB-SI Fire Safety Requirements for Murcia’s Building Renovation Projects

Murcia’s historic city center, particularly the Casco Antiguo district, presents unique challenges for fire safety upgrades. Renovation projects in these heritage zones must comply with CTE DB-SI Section 4, which governs compartmentation and fire spread prevention. This section often requires EI 60 or EI 120 rated glazing in critical locations such as stairwells, atrium enclosures, and corridor separations. The difficulty lies in integrating modern fire-resistant materials without altering the visual character of historic facades and interiors. Antifires addresses this with advanced fire partition solutions that combine slim-profile steel frames with high-performance glass, such as the 21mm FPOS (Integrity 120 min, Insulation 30 min) or the 28mm EI60 panel (Integrity 66 min, Insulation 64 min). These systems allow for large, transparent openings that maintain sightlines and natural light, essential for preserving the openness of historic courtyards and stairwells. Furthermore, the installation methodology—using ceramic wool (3mm–6mm, density 210 kg/m³) and intumescent seals (20mm × 4mm)—ensures that the glazing unit expands under heat to seal gaps, preventing smoke and flame passage while respecting the original building fabric. This technical approach enables compliance with local heritage regulations without compromising life safety.

Fire Rated Glass Grade Selection for Murcia’s Mediterranean Climate and Seismic Zone

New commercial developments in Murcia’s expanding Polígono Industrial Oeste require glazing systems that can withstand both the region’s Mediterranean climate (high humidity, temperature swings) and its seismic activity (Zone 3 per Spanish seismic standard NCSE-02). For these environments, the selection of fire rated glass must consider thermal expansion, moisture resistance, and structural integrity under dynamic loads. Antifires provides systems tested under EN 1363-1 furnace conditions and EN 1634-1 door certification, ensuring performance in real-world scenarios. The recommended grades for high-traffic retail units and office spaces are as follows:

ApplicationRecommended GlassFire RatingKey Feature

Office Partitions28mm EI60Integrity 66 min / Insulation 64 minHigh insulation for evacuation routes
Atrium Enclosures50mm EI120Integrity 120 min / Insulation 120 minStructural stability under seismic deflection

These systems utilize multi-layer tempered glass with intumescent gel layers (e.g., 6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm for 28mm EI60), which provide both fire resistance and impact safety. The frames are anchored with M6/M8 bolts at 300–600mm spacing, ensuring the assembly remains intact during seismic events while maintaining the required fire separation.

Fire Rated Glass Applications in Murcia’s Healthcare and Educational Infrastructure

Murcia’s healthcare and educational infrastructure, including hospitals like Hospital Clínico Universitario Virgen de la Arrixaca and new school campuses, demands the highest levels of passive fire protection. These facilities require EI 60 or EI 120 rated glazing in corridors, waiting areas, and classroom separations to ensure safe evacuation of vulnerable occupants. Antifires provides certified solutions that meet these stringent requirements without sacrificing natural light or visibility, which are critical for patient well-being and learning environments. For example, the 26mm door glass system (Integrity 89–90 min, Insulation 68 min) is ideal for fire-rated doors in hospital wards, offering a balance of transparency and thermal protection. In educational settings, the 21mm FPOS glass (Integrity 120 min, Insulation 30 min) can be used in partition walls to create safe zones while allowing supervision of students. All systems are tested with furnace thermocouples (Type K, 9–12 channels) and unexposed surface monitoring (10–55 thermocouples) to verify that the average temperature rise on the unexposed side remains below 140°C, and the maximum below 180°C, as per EN 1364-1. This data-driven assurance is vital for project specifications in Murcia’s public sector tenders, where compliance with CTE DB-SI and regional safety directives is mandatory. Antifires also provides detailed test reports and installation guidelines, enabling seamless integration into existing building management systems.
