Adapting Fire Resistance Requirements for Sevilla’s Historic and Modern Building Stock Under CTE DB SI
Sevilla’s building landscape presents a unique challenge for fire protection engineers. The CTE DB SI requires different fire resistance ratings depending on whether a project involves a historic rehabilitation or a new commercial tower. For example, in the Santa Cruz district, where many structures feature timber floors and narrow staircases, upgrading compartmentation often requires EI 30 or EI 60 rated glazed partitions that offer both integrity and insulation without compromising aesthetic continuity. In contrast, the high-rise office towers on the Isla de la Cartuja demand higher ratings, such as EI 90 or EI 120, to ensure safe evacuation and limit fire spread between floors. Antifires’ product range addresses both scenarios:
- Historic rehabilitation: Thin-profile fire rated glass systems (e.g., 10mm FPOS) that fit existing frames while providing up to 135 minutes of integrity.
- New construction: Multi-layer insulated glass (e.g., 50mm EI120) that combines fire resistance with thermal and acoustic performance.
Each assembly is designed to accommodate the movement and deflection typical of Sevilla’s older masonry walls, using intumescent seals and ceramic wool to maintain a fire-tight barrier. This localized engineering approach ensures compliance without requiring structural overhauls.
Selecting Fire Rated Glass Grades for Sevilla’s Climate: Solar Control and EI Integrity Performance
Sevilla’s hot Mediterranean climate, with summer temperatures often exceeding 40°C, adds a layer of complexity to fire-rated glazing selection. Architects and specifiers must balance EI integrity and insulation performance with solar control to maintain occupant comfort and energy efficiency. Antifires addresses this by offering fire-rated glass units that incorporate low-emissivity coatings and solar control interlayers within the certified assembly. For instance, the 21mm FPOS glass provides 120 minutes of integrity and 30 minutes of insulation while reducing solar heat gain, making it suitable for curtain walls in commercial plazas. For door applications, the 26mm glazed door glass achieves 89–90 minutes of integrity and 68 minutes of insulation, with a structure that minimizes thermal bridging. All products are tested under EN 1634-1 and classified per EN 13501-2, ensuring that the solar control features do not compromise the fire resistance rating. This dual functionality allows Sevilla’s buildings to meet both safety and sustainability goals without requiring separate shading systems.
Engineering Fire Protection for Sevilla’s Key Sectors: Hotels, Hospitals and Commercial Plazas
In Sevilla’s key sectors—hotels, hospitals, and commercial plazas—fire protection requirements are particularly stringent due to high occupant loads and vulnerable populations. The CTE DB SI mandates that escape routes and compartment walls in these buildings achieve specific EI ratings, often EI 60 or higher. Antifires provides tailored solutions for each sector:
- Hotels: Corridor partitions and lobby glazing using fire door systems with EI 60 ratings, tested to EN 1634-1, ensuring safe egress from guest rooms.
- Hospitals: Radiation-control (W) glass for ICU and operating room viewing panels, limiting heat transfer to protect sensitive equipment and patients.
- Commercial plazas: Large-span curtain walls using 50mm EI120 insulated glass, providing both fire compartmentation and thermal comfort for retail spaces.
Each installation is supported by detailed fire engineering reports and on-site technical guidance from Antifires’ Andalucía-based team, ensuring that the final assembly meets both the letter and spirit of local regulations.
Antifires’ Track Record in Andalucía: Local Stock, Technical Support and EN-Certified Quality
Antifires has established a strong track record across Andalucía, including in Sevilla, by maintaining local stock and providing direct technical support. The company’s commitment to quality is evident in its use of third-party accredited test laboratories for all products, ensuring compliance with EN 1634-1, EN 1364-1, and BS 476 Part 22. For Sevilla contractors, this means access to certified fire rated glass and fire partition solutions that are ready for immediate delivery and installation. Antifires also offers installation training sessions covering proper frame integration, sealant application, and expansion gap management—critical factors for achieving the rated performance in the field. With a warehouse in the region, the company can supply both standard and custom sizes for projects ranging from small boutique renovations to large-scale commercial developments. This localized infrastructure, combined with European-certified quality, makes Antifires a trusted partner for fire safety in Sevilla.
