ABNT NBR 11711 Compliance for Fire Resistant Glazing in Parana State
Maringa’s growing portfolio of high-rise commercial and industrial buildings requires fire resistant glazing that complies strictly with ABNT NBR 11711 and local Parana fire brigade regulations. This standard specifies performance levels for fire-rated glass based on the required duration of resistance, typically ranging from 30 to 120 minutes for integrity. Antifires ensures that each glazing system, whether used in doors, windows, or partitions, is tested and certified to meet these regional benchmarks. The technical approach involves using multi-layer laminated glass constructions with intumescent interlayers that activate under heat to form an opaque, insulating barrier. For example, the 21mm FPOS composite structure, which combines multiple layers of tempered glass with fire-resistant gel, has demonstrated integrity for 120 minutes under BS 476 Part 22 test conditions, directly supporting compliance with local requirements for high-occupancy spaces. Key considerations for specifiers in Maringa include:
- Integrity (E) Rating: Ensuring the glass prevents flame and hot gas penetration for the required duration, typically 60 or 90 minutes for commercial egress routes.
- Insulation (I) Rating: Limiting temperature rise on the unexposed side to an average of 140°C and a maximum of 180°C, critical for protecting adjacent combustible materials.
- System Certification: Verifying that the complete assembly—including frame, sealant, and glazing—has been tested as a unit, as required by ABNT NBR 11711.
Antifires provides full technical documentation to support project approvals, including test reports that reference these specific performance criteria.
Selecting E120 Fire Rated Glass for Maringa’s High-Rise Facade Demands
For Maringa’s expanding skyline, particularly in buildings exceeding ten stories, the selection of E120 classification fire rated glass offers a robust solution for facade applications. This rating indicates a verified capability to maintain integrity for 120 minutes under standardized fire test conditions, such as those defined in BS 476 Part 22 or ASTM E119. The high-performance glazing recommended for these demanding scenarios typically employs a multi-layer laminated structure, such as the 50mm or 54mm ultra-high-performance glass, which combines multiple panes with intumescent interlayers. This design is critical for resisting the thermal shock that can occur during a fire, especially when combined with the intense solar radiation common in Maringa’s tropical climate. The intumescent layers, when exposed to fire temperatures, expand to create a stable, insulating barrier that prevents glass fall-out and maintains the compartment’s integrity. Additionally, the laminated construction provides inherent resistance to thermal stress from daily sun exposure, reducing the risk of spontaneous breakage. Key technical features of E120 systems include:
- Thermal Stability: The multi-layer design with intumescent gel (e.g., 6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) absorbs and dissipates heat, maintaining structural stability for up to 120 minutes.
- Optical Clarity: Despite the complex internal structure, the glass maintains high light transmission, essential for modern architectural aesthetics and daylighting strategies.
- System Integration: These glazing units are installed in G.M.S. hollow steel frames with ceramic wool and intumescent seals, ensuring the entire facade assembly performs as a certified unit.
Fire Rated Partition Systems for Maringa Shopping Centers and Warehouses
Local commercial hubs such as Maringa Park shopping center and the expanding logistics warehouse districts require robust compartmentation solutions to protect life and property. Antifires supplies fire rated glass doors and fixed windows specifically designed for these high-traffic environments, ensuring that escape routes remain tenable and smoke-free during a fire emergency. The systems are engineered to integrate seamlessly with building sprinkler and smoke management systems, providing a complete passive fire protection strategy. For shopping centers, where large open-plan areas must be subdivided, fire rated glass partitions with integrity ratings of 60 to 90 minutes are commonly specified. These partitions use certified glazing like the 26mm door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm), which has demonstrated integrity for 89–90 minutes and insulation for 68 minutes under test conditions. In warehouse applications, where fire loads can be high, the focus is on preventing fire spread across large floor areas. Antifires provides fixed glazed screens and doors that achieve EI60 or EI120 ratings, using systems such as the 28mm EI60 panel (integrity 66 min, insulation 64 min) or the 50mm EI120 assembly. These products are installed with fire-rated insulation boards (12mm–15mm) and ceramic fiber expansion gaps (3mm–5mm) to ensure a complete seal against smoke and flames.
Antifires Localized Stock and Technical Support for Maringa Contractors
To support Maringa contractors and project managers, Antifires maintains a strategic stock of pre-certified fire rated glass products at its distribution hub in Curitiba. This central location enables rapid delivery to construction sites throughout the Parana region, typically within 48 to 72 hours for standard product lines. The stocked inventory includes a range of integrity-only and combined integrity-insulation glass systems, from basic 6mm E90 glass to advanced 54mm EI120 assemblies, all accompanied by full Brazilian technical documentation. Beyond logistics, Antifires provides dedicated technical support to ensure correct specification and installation. This includes onsite guidance for frame preparation, sealant application, and anchoring systems (M6/M8 bolts at 300–600mm spacing), as well as assistance with local fire department approvals. The team can provide test reports and compliance certificates that directly reference ABNT NBR 11711 and international standards like BS EN 1634-1, streamlining the project approval timeline. For contractors working on complex facade or partition systems, access to 120-minute fire rated glass with integrity and insulation ensures that even the most demanding specifications are met with certified, ready-to-install products. This localized support model reduces the risk of installation errors and accelerates project completion, making Antifires a reliable partner for Maringa’s construction industry.
