Navigating Swedish Fire Safety Codes and BBR Compliance for Västerås Construction
Navigating the Swedish BBR regulations requires a precise understanding of how fire resistance classes apply to glazed construction. The BBR mandates that fire compartment walls and doors must achieve specific EI ratings, where "E" denotes integrity against flame penetration and "I" denotes thermal insulation. For Västerås projects, Antifires offers systems tested to SS-EN 13501-2, with certified ratings from EI 30 to EI 120. The technical foundation of these products lies in multi-layered glass structures incorporating intumescent interlayers. During a fire event, these interlayers expand to form an opaque thermal barrier, effectively limiting temperature rise on the unexposed side to an average of ≤140°C, as validated by furnace tests. This performance is critical for maintaining compartmentation integrity and protecting evacuation routes in commercial and residential buildings across Västerås. The following table summarizes key compliance parameters:
| BBR Requirement | Antifires Solution | Test Standard |
| EI 30 for escape routes | Multi-layer glazing with intumescent gel | BS EN 1364-1 |
| EI 60 for fire compartments | 28mm composite glass system | BS 476 Part 22 |
| EI 120 for high-risk zones | 50mm insulated fire-resistant glass | BS EN 1634-1 |
Selecting Fire Rated Glass Grades with Verified Technical Performance for Västerås Climates
Västerås experiences a variable Nordic climate, with significant temperature differentials between heated interiors and cold outdoor conditions. This places unique demands on fire rated glazing, particularly regarding thermal shock resistance and condensation prevention. Antifires addresses these challenges with multi-layered glass solutions that combine fire protection with enhanced thermal performance. Products such as the 21mm FPOS and 28mm EI60 panels are constructed with multiple glass layers and fire-resistant gels that provide tested insulation values while reducing heat transfer. For example, the 28mm EI60 panel has demonstrated integrity for 66 minutes and insulation for 64 minutes under standard furnace conditions, ensuring reliable performance during a fire event. Additionally, the use of advanced frame systems with thermal breaks and ceramic wool seals (density 210 kg/m³) minimizes condensation risk by maintaining consistent surface temperatures. When selecting fire rated glass for Västerås projects, professionals should consider the U-value of the complete assembly and the specific expansion gap requirements (3–5mm filled with ceramic fiber) to accommodate thermal movement without compromising the fire seal.
Addressing Fire Safety Demands in Västerås Historic Centres and New Industrial Zones
Västerås urban landscape presents a dual challenge: preserving historic structures near the Cathedral and supporting modern developments in areas like Mälardalen University campus and the Västerås Science Park. For heritage buildings, retrofitting fire rated glazing requires slim-profile systems that maintain architectural aesthetics while meeting modern safety codes. Antifires supplies custom-fit fire rated windows and doors with steel frames (G.M.S. hollow sections) that can be integrated into existing openings without altering the building’s character. These systems achieve integrity ratings of up to 90 minutes, as verified by BS 476 Part 22 tests, while preserving sightlines. In contrast, new industrial zones demand robust solutions for large-span curtain walls and partition systems. For these applications, Antifires offers 50mm and 54mm ultra-high-performance glass units that achieve EI 120 ratings (integrity and insulation up to 120 minutes). These systems are designed for steel-frame structures and can withstand the deflection forces (up to 152mm toward the furnace) typical of large-scale fire tests, ensuring reliable compartmentation in high-occupancy facilities.
Why Västerås Contractors Trust Antifires for Certified Fire Protection and Local Support
Västerås contractors and specifiers choose Antifires for a combination of certified product performance and localized support. Every fire rated glass assembly is supplied with full CE marking and a Declaration of Performance (DoP) in both Swedish and English, directly addressing the documentation requirements of local building inspectors. This traceability is essential for insurance approvals and regulatory sign-off. Antifires also maintains a dedicated logistics channel for Scandinavian orders, ensuring timely delivery to Västerås project sites. For on-site installation, regional partners provide guidance on critical details such as anchor bolt spacing (M6/M8, 300–600mm intervals) and the correct application of intumescent fire seals (20mm × 4mm) within frames. This reduces the risk of installation errors that could compromise fire performance. Furthermore, Antifires offers a comprehensive range of fire partition solutions, allowing contractors to source all glazed fire protection elements from a single certified supplier, streamlining procurement and ensuring system compatibility across the entire project.
