Compliance with ABNT NBR 11742 and SCDF Standards for Betim Projects
Betim's building sector, particularly in its expanding industrial zones, mandates fire-rated materials that strictly comply with ABNT NBR 11742 and local fire safety codes. Antifires' fire-rated glazing systems are engineered to meet these specifications, providing verified integrity (E) and insulation (I) performance that satisfies both national and international approval processes. The products undergo testing under conditions that simulate real-world fire scenarios, including furnace pressure control and thermocouple monitoring, ensuring reliable behavior during emergencies. Key compliance features include:
- Certified test reports aligned with ABNT NBR 11742 and SCDF-equivalent standards.
- Multi-layer glass compositions (e.g., 10mm FPOS, 21mm FPOS) that provide up to 120 minutes of integrity and insulation.
- Fire-rated frames and sealants using G.M.S. hollow steel sections, ceramic wool (density 210 kg/m³), and intumescent seals (20mm × 4mm).
- Installation protocols specifying expansion gaps (3–5mm) filled with ceramic fiber to maintain structural stability under heat.
These elements ensure that Betim's high-risk facilities, such as chemical plants and automotive assembly lines, achieve the required fire compartmentation without compromising design flexibility.

Selecting Fire Rated Glass EI and EW Classes for Betim’s Climate Conditions
Betim's tropical climate presents unique challenges for fire-rated glazing, as thermal stress from high ambient temperatures and humidity can affect glass integrity over time. Antifires addresses this by offering EI (integrity and insulation) and EW (integrity and radiation control) classes with tested ratings from 30 to 120 minutes, validated under ABNT NBR test conditions. The selection process for Betim projects considers:
| Class | Performance Criteria | Typical Application |
| EI30 | Integrity + Insulation (max avg. temp rise ≤140°C) | Internal partitions in climate-controlled offices |
| EI60 | Integrity + Insulation (tested up to 66 min integrity, 64 min insulation) | Warehouse compartment walls near steel mills |
| EW120 | Integrity + Radiation control | Glazed facades in high-heat industrial zones |
For Betim's steel mills and chemical plants, EI60 or EI120 rated glass (e.g., 28mm or 50mm multi-layer structures) is recommended to withstand local temperature fluctuations while maintaining fire separation. The multi-layer tempered glass with intumescent gel absorbs thermal expansion, preventing premature failure. To explore specific product configurations, review 60-minute fire-rated glass with insulation for tropical climate resilience.
Fire Rated Applications in Betim’s Petrochemical and Automotive Hubs
Betim hosts major automotive and petrochemical facilities where fire compartmentation is critical in warehouses, production lines, and high-storage rack zones. Antifires provides specialized fire rated glass partitions and doors that deliver 60-minute fire separation, reducing the risk of fire spread in open-plan assembly areas. These systems are engineered to withstand the dynamic loads and thermal stresses typical of industrial environments. Key applications include:
- Automotive assembly lines: Glazed partitions with EI60 ratings allow visual monitoring while containing fire within designated zones.
- Petrochemical storage areas: EW120 rated glass doors control radiant heat transmission, protecting adjacent high-storage rack zones.
- Warehouse compartment walls: Multi-layer glass (e.g., 21mm FPOS) with 120-minute integrity ensures structural stability in large-span areas.
The installation uses G.M.S. hollow steel frames with ceramic wool and intumescent seals to maintain fire resistance at joints. For Betim's industrial hubs, these systems are tested under conditions simulating real fire exposure, including furnace pressure of 0±2Pa and thermocouple monitoring. To see how these systems integrate into production lines, explore fire-rated glass partitions designed for industrial compartmentation.
Antifires Localized Engineering Support and Certified Product Traceability
Antifires delivers factory-traceable fire rated glass with comprehensive test reports compliant to ABNT NBR and international standards such as BS 476 Part 22 and BS EN 1634-1. For Betim projects, the company offers localized engineering support, including on-site technical audits to verify correct installation and long-term certification validity. Key support services include:
- Pre-installation audits: Review of frame specifications, expansion gaps (3–5mm), and sealant types (e.g., ceramic fiber, intumescent tape).
- Installation supervision: Ensuring anchor bolt spacing (300–600mm), ceramic wool density (210 kg/m³), and pressure conditions align with test protocols.
- Documentation traceability: Providing certified test reports with furnace thermocouple data and unexposed surface monitoring (10–55 channels).
This localized approach ensures that Betim's building inspectors receive verifiable evidence of compliance, reducing approval delays. For projects requiring specific door systems, Antifires offers fire-rated glass doors with full traceability to certified test data.
