Aligning with Caruaru’s Fire Safety Regulations Under Brazil’s NBR 11742 and State Codes
Caruaru’s building projects must align with ABNT NBR 11742, which specifies the fire resistance test method for construction elements, and NBR 15247, which governs fire door assemblies. These standards are enforced by the Pernambuco Fire Department (CBMPE), requiring that all glazed systems in commercial and institutional buildings achieve verified integrity and, where specified, insulation performance. Antifires products are engineered to meet these local classification requirements through precise structural composition. For instance, the 28mm EI60 panel—comprising a multi-layer tempered glass structure with intumescent gel—achieves an integrity rating of 66 minutes and an insulation rating of 64 minutes under BS EN 1364-1 test conditions. This performance ensures compliance with Caruaru’s fire safety regulations for high-occupancy zones, such as shopping centers and office towers. The systems utilize G.M.S. hollow steel frames with ceramic wool seals (density 210 kg/m³) and intumescent fire seals (20mm × 4mm), which are critical for maintaining compartmentation during a fire. For projects requiring detailed documentation, Antifires provides Portuguese-language technical reports that reference these NBR standards, facilitating smoother approval processes with local authorities.

Selecting Fire Rated Glass Grades for Caruaru’s Climate and NBR 11742 Performance Criteria
Selecting the appropriate fire rated glass grade for Caruaru requires careful consideration of the region’s climate conditions and the performance criteria defined by NBR 11742. Recent updates to Pernambuco’s state fire code mandate passive fire protection in high-occupancy commercial zones, particularly in Caruaru’s expanding shopping districts and mixed-use developments. Antifires offers graded solutions based on certified test data: for integrity-only applications, the 6mm E90 glass provides 90 minutes of fire resistance under BS 476 Part 22, suitable for internal partitions where insulation is not critical. For areas requiring both integrity and insulation—such as evacuation corridors near the BR-104 highway—the 50mm EI120 system delivers 120 minutes of both ratings, utilizing a multi-layer insulated fire-resistant structure. The table below summarizes key performance grades relevant to Caruaru projects:
| Glass Type | Integrity (Minutes) | Insulation (Minutes) | Typical Application |
| 6mm E90 | 90 | N/A | Internal partitions |
| 28mm EI60 | 66 | 64 | Door assemblies |
| 50mm EI120 | 120 | 120 | Stairwell enclosures |
These systems are tested under furnace conditions with type K thermocouples and controlled pressure differentials, ensuring reliable performance in Caruaru’s variable humidity (43%–90% RH during tests). Documentation is provided to support compliance with regional specifications.
Addressing Caruaru’s Building Application Scenarios in Commercial and Industrial Hubs
Caruaru’s growth in textile manufacturing and retail centers demands robust fire-rated partitions in warehouses and showrooms. Antifires systems provide effective compartmentation for stairwells and elevator lobbies in mixed-use developments near the BR-104 highway. In these scenarios, the 21mm FPOS glass—with an integrity rating of 120 minutes and insulation of 30 minutes—offers a balance of thermal protection and visual transparency for showroom environments. For industrial warehouses, the 15mm FPOS (integrity up to 132 minutes, insulation 33–34 minutes) is suitable for separating storage zones from office areas. These systems are installed using G.M.S. hollow steel frames with M6/M8 anchor bolts spaced at 300–600mm intervals, and expansion gaps of 3–5mm filled with ceramic fiber to accommodate thermal movement. In retail corridors, the 90-minute fire rated glass for windows and partitions ensures that escape routes remain smoke-free and structurally sound. The maximum deflection observed during testing—38mm to 152mm toward the furnace—is accounted for in frame design to prevent premature failure. These solutions integrate seamlessly with existing steel frames, making them ideal for retrofit projects in Caruaru’s older commercial districts.
Why Caruaru Contractors Choose Antifires for Certified Fire Protection and Supply Chain Reliability
Local hospitals and educational institutions in Caruaru’s Universitário district demand fire windows with 60-minute ratings for patient safety corridors and classroom egress paths. Antifires products, such as the 26mm door glass (integrity 89–90 minutes, insulation 68 minutes), are engineered to integrate with existing steel frames for retrofit projects, minimizing structural disruption. The systems utilize ceramic wool (3–6mm thickness) and intumescent seals to maintain fire resistance at frame interfaces. For supply chain reliability, Antifires maintains stock of certified glass units and frame components, ensuring timely delivery to Caruaru construction sites. The 8mm glass system (integrity 73 minutes) offers a cost-effective solution for secondary partitions where full insulation is not mandated. All products are accompanied by test reports from accredited laboratories, referencing BS 476 Part 22 and BS EN 1634-1 standards, which align with NBR 11742 requirements. Contractors benefit from Portuguese-language technical support and installation guidelines, reducing on-site errors. This combination of certified performance and logistical dependability makes Antifires a preferred partner for Caruaru’s healthcare and education projects, where fire safety compliance is non-negotiable.
