Campinas Fire Safety Codes: Adapting to NBR 11742 and Regional Building Regulations
Campinas’ building codes are heavily influenced by the São Paulo State Fire Department (CBPMESP) Technical Instructions, which mandate specific fire resistance ratings (TRRF) based on building height, occupancy, and risk classification. The primary standard governing glazed fire door assemblies is ABNT NBR 11742, which defines requirements for integrity (E) and insulation (I) performance. For non-loadbearing glazed partitions and walls, NBR 15247 outlines the test methodology, closely aligned with international norms like BS EN 1364-1. Antifires’ engineered systems are tested to these principles, ensuring that assemblies maintain their fire-separating function under standard fire curves. In high-density commercial zones such as the Cambuí district, egress corridors and stairwell enclosures often require EI 60 or EI 120 ratings. The company’s 28mm EI60 panel, for example, demonstrates 66 minutes of integrity and 64 minutes of insulation, providing a compliant solution for these demanding applications. The use of intumescent interlayers and ceramic wool edge seals (density 210 kg/m³) ensures that the glass assembly expands under heat, maintaining the barrier against smoke and flame.
Selecting Fire Rated Glass Grades for Campinas: Technical Parameters for EI and EW Classifications
Selecting the correct fire-rated glass grade for Campinas projects requires a clear understanding of EI (Integrity + Insulation) versus EW (Integrity + Radiation Control) classifications. For internal stairwells and escape routes where occupants are in close proximity to the glazing, EI-rated glass is essential to limit surface temperature rise to a maximum of 180°C (average 140°C). Antifires offers a range of certified products tailored to these needs. For instance, the 26mm door glass achieves 89–90 minutes integrity and 68 minutes insulation, making it suitable for high-traffic egress doors. In contrast, EW 120 systems, such as the 50mm or 54mm ultra-high-performance glass, control radiant heat flux while providing 120 minutes of integrity, ideal for large atrium partitions where visual transparency is prioritized. The table below summarizes key performance grades for typical Campinas applications:
| Product Thickness |
Rating |
Typical Application |
| 10mm FPOS |
E 135 / I 16 |
Small vision panels in fire doors |
| 26mm Door Glass |
E 90 / I 68 |
Egress door assemblies |
| 28mm EI60 Panel |
E 66 / I 64 |
Corridor partitions |
| 50mm EI120 |
E 120 / I 120 |
Large atrium walls |
All products are tested with G.M.S. hollow steel frames and intumescent fire seals (20mm x 4mm), ensuring system-level certification.
Building Application Scenarios: Campinas Industrial Warehouses and Commercial Mall Projects
Campinas’ diverse building typologies—from industrial warehouses in the Distrito Industrial to commercial malls in the Centro—demand versatile fire-rated glazing solutions. For industrial warehouses housing flammable materials, the 21mm FPOS glass (120 minutes integrity, 30 minutes insulation) provides a robust barrier for internal fire compartments and mezzanine enclosures. Its multi-layer composite structure, incorporating tempered glass and intumescent gel, maintains stability under high thermal loads. In commercial mall projects, such as those along Avenida José de Souza Campos, large-span glazed partitions are often required to separate retail units from common corridors. Here, the 50mm EI120 system offers full insulation performance for 120 minutes, allowing for uninterrupted visual sightlines while meeting CBPMESP’s strict TRRF requirements. For retrofit projects in older buildings, the 8mm glass system (73 minutes integrity) can be installed into existing steel frames using ceramic tape edge seals (3mm–6mm thickness) and M6 anchor bolts spaced at 300mm intervals, minimizing structural modifications. Each installation follows a standardized protocol: maintaining a 3mm–5mm expansion gap filled with ceramic fiber to accommodate thermal movement without compromising the fire seal.
Antifires Brand Advantages: Localized Technical Support and NBR-Certified Product Traceability
Antifires distinguishes itself in the Campinas market through localized technical support and full NBR-certified product traceability. Every glazing assembly is accompanied by a detailed test report referencing BS 476 Part 22 and BS EN 1634-1 methodologies, which are accepted by CBPMESP as equivalent evidence of compliance with NBR 15247. The company maintains a dedicated team of fire protection engineers who assist with project-specific calculations, including glass thickness selection and frame integration. The 120 minute fire rated glass product line, for example, provides documented performance data for both integrity and insulation, enabling specifiers to confidently meet the highest TRRF levels. Additionally, all products are manufactured with fire-rated insulation boards (12mm–15mm) and ceramic wool ensuring consistent quality across every order. For projects requiring rapid delivery, the company offers expedited lead times for standard sizes, with custom dimensions fabricated within 10–15 working days. This combination of certified performance, technical expertise, and supply chain reliability makes Antifires a trusted partner for Campinas’ evolving construction sector.
