Local Fire Safety Codes and ABNT NBR 11742 Compliance for Mogi das Cruzes
Building projects in Mogi das Cruzes must adhere to the technical fire safety regulations established by the São Paulo State Civil Defense, which mandate that all glazed assemblies in critical egress paths and industrial partitions comply with ABNT NBR 11742. This standard specifies the fire resistance requirements for glass and framing components used in doors, windows, and curtain walls. For example, a commercial building in the city center, such as a school or shopping mall, typically requires a minimum of 60 minutes of fire integrity (E60) for internal glazed partitions. Antifires addresses this with systems like the 6mm E90 glass, which provides 90 minutes of integrity, exceeding the basic requirement and offering a safety margin for high-occupancy environments.
Key compliance considerations for local projects include:
- Egress Path Protection: Glazed doors and sidelights must maintain fire integrity to prevent smoke and flame spread, with tested systems like the 26mm door glass (Integrity: 89–90 min; Insulation: 68 min) ensuring safe evacuation routes.
- Industrial Partitioning: For warehouses and factories, assemblies must resist fire for longer durations (e.g., 120 minutes). Antifires’ 50mm EI120 system provides both integrity and thermal insulation, meeting the demands of large open-plan spaces.
- Frame and Sealant Standards: All installations use G.M.S. hollow steel frames, ceramic wool (density 210 kg/m³), and intumescent seals (20mm × 4mm) to ensure the entire assembly, not just the glass, meets the fire-resistance rating.
These technical specifications align directly with the São Paulo state code updates, which increasingly require third-party certification for all passive fire protection products. Antifires provides full documentation linking each system to its tested performance, simplifying the approval process with local fire marshals.
Fire Rated Glass Integrity Ratings and Thermal Insulation Parameters for Local Projects
Antifires provides a diverse range of fire rated glass and door systems that deliver verified integrity (E) and thermal insulation (I) performance, critical for meeting the specific fire resistance levels required by Mogi das Cruzes building codes. For projects demanding basic life safety, such as corridor doors in residential towers, the 6mm E90 glass offers 90 minutes of integrity without insulation. This is ideal for areas where preventing flame passage is the primary concern, and the unexposed side temperature rise is not critical. In contrast, for applications like fire-rated partitions in hospital stairwells or school assembly areas, thermal insulation is essential to protect occupants and allow safe passage.
The table below summarizes key performance parameters for common project scenarios in Mogi das Cruzes:

For high-occupancy structures like shopping centers in the city center, where fire loads are high and evacuation times are longer, the 26mm door glass (Integrity: 89–90 min; Insulation: 68 min) provides an excellent balance of performance. It ensures that in the event of a fire, the unexposed side remains below the critical 140°C average temperature rise for over an hour, allowing firefighters and occupants to move safely through the compartment. Antifires’ engineering team can help specify the correct insulation rating (EI30, EI60, or EI120) based on the building’s fire load and occupancy classification, ensuring full compliance with updated local codes.
Industrial Warehouses and Commercial Facades Demanding Fire Partition Systems in Mogi das Cruzes
Mogi das Cruzes’ industrial warehouses and commercial facades present unique fire safety challenges due to large open spaces, high fire loads, and the need for natural light. Antifires addresses these demands with fire partition solutions that combine structural integrity with thermal insulation, ensuring that fire compartments remain intact for up to 120 minutes. For example, a logistics warehouse in the city’s industrial district may require a 120-minute fire-rated curtain wall to separate storage areas from office spaces. The 50mm EI120 system, with its multi-layer insulated structure, provides both integrity and insulation for the full duration, preventing heat transfer that could ignite adjacent materials.
Key systems for these demanding environments include:
- Industrial Partitioning: The 28mm EI60 panel (Integrity: 66 min; Insulation: 64 min) is ideal for separating production zones from storage, offering a cost-effective solution for 60-minute compartments.
- Commercial Facades: For shopping centers and office buildings, the 21mm FPOS (Integrity: 120 min; Insulation: 30 min) allows large glazed areas without compromising fire safety, supporting modern architectural aesthetics.
- High-Performance Glazing: The 50mm / 54mm ultra-high-performance glass is engineered for extreme conditions, such as in chemical storage warehouses, where both fire and thermal shock resistance are critical.
Installation in these scenarios requires precise engineering to manage expansion and deflection. Antifires uses G.M.S. hollow steel frames with 3mm–5mm expansion gaps filled with ceramic fiber, and anchor bolts spaced at 300–600mm intervals to ensure the assembly withstands furnace pressures of 0 ±2Pa. This level of detail ensures that the entire system, from the fire partition solutions to the framing, performs as tested, providing reliable protection for Mogi das Cruzes’ most critical industrial and commercial assets.
Antifires Localized Engineering Support and ABNT-Certified Product Assurance for Mogi das Cruzes
Antifires offers comprehensive localized engineering support for projects in Mogi das Cruzes, ensuring that every fire rated glass and door system is not only ABNT-certified but also optimized for local installation conditions. The company’s technical team works directly with architects, contractors, and fire safety consultants to provide system-specific shop drawings, load calculations, and installation guidelines that align with the São Paulo State Civil Defense requirements. This includes verifying that all assemblies—such as fire door systems—are installed with the correct intumescent seals, ceramic wool packing, and anchor bolt spacing as per the original test reports.
Key aspects of Antifires’ localized support include:
- Pre-Installation Audits: Review of site conditions (ambient temperature, humidity, and substrate) to ensure they match the test conditions (27°C–36°C, 43%–90% RH) documented in the certification.
- Certification Documentation: Provision of full test reports (e.g., BS 476 Part 22, BS EN 1634-1) that directly correlate to the ABNT NBR 11742 requirements, simplifying local fire marshal approvals.
- On-Site Training: For large projects like the new shopping center in the city center, Antifires provides on-site training for installation crews, covering proper sealant application, frame alignment, and expansion gap management.
This engineering assurance is backed by a rigorous quality control process. Every system is traceable to its original test data, ensuring that the fire partition solutions delivered to Mogi das Cruzes projects perform exactly as certified. By combining global testing standards with local regulatory expertise, Antifires eliminates the risk of non-compliance, providing peace of mind for developers and building owners.
