Swiss Cantonal Fire Protection Regulations and Winterthur Building Code Compliance
Winterthur construction projects must comply with the VKF (Vereinigung Kantonaler Feuerversicherungen) standards, specifically the Swiss Fire Protection Norm (Brandschutznorm) and Technical Directives (Brandschutzrichtlinien). These regulations mandate that all glazed elements in escape routes, stairwells, and compartment walls achieve defined fire resistance classes, typically EI 30 or EI 60. Antifires ensures every fire-rated glass and door system is tested and certified to meet these requirements for public and commercial buildings in the canton of Zürich. The compliance process involves verifying that the glass composition, frame materials, and sealant systems—such as ceramic wool and intumescent seals—function as a unified barrier. For example, our 28mm EI60 panel delivers verified integrity and insulation performance, making it suitable for high-traffic corridors in Winterthur’s office towers. By aligning with the VKF’s technical directives, Antifires provides a streamlined path to building permit approval, reducing project delays and ensuring that all fire protection measures are legally sound.
Fire Rated Glass Performance Grades for Winterthur’s Architectural Specifications
Selecting fire-rated glazing for Winterthur projects requires a focus on certified integrity (E) and insulation (I) ratings, as defined by EN 13501-2 and VKF certification. Antifires offers a spectrum of fire-resistant glass solutions, from E30 to EI120, each tested under standardized furnace conditions to ensure reliable performance. Key technical parameters include low U-values for energy efficiency and compatibility with standard Swiss window frames, which is critical for retrofitting in historic buildings. The table below summarizes typical performance grades and their applications in Winterthur’s architectural specifications:
| Fire Resistance Class |

Additionally, our 60-minute fire-rated glass systems are designed to integrate seamlessly with aluminum or steel frames, ensuring thermal performance without compromising fire safety.
Application of Fire Rated Systems in Winterthur’s Commercial and Residential Complexes
Winterthur’s urban development projects, such as office towers in the Technorama district and mixed-use residential blocks in Oberwinterthur, require robust compartmentation solutions to manage fire spread and ensure safe evacuation. Antifires fire doors, glazed partitions, and fire windows are specified for critical areas including escape routes, stairwells, and atrium enclosures. In commercial complexes, our EI60-rated door glass (26mm structure) provides integrity for up to 90 minutes and insulation for 68 minutes, offering extended protection for high-occupancy floors. For residential blocks, E30 glazed partitions are often used in corridor separations, allowing natural light while maintaining fire barriers. In atrium enclosures, EI120 systems (50mm or 54mm glass) control both flame and heat transmission, preventing vertical fire spread. These applications are supported by detailed installation protocols, including the use of ceramic wool (3–6mm, density 210 kg/m³) and intumescent fire seals (20mm × 4mm) to ensure system integrity. By tailoring solutions to Winterthur’s specific building typologies, Antifires helps contractors achieve both aesthetic goals and strict fire safety compliance.
