Aligning with Maceió’s Building Fire Safety Codes and NBR 14432 Standards
Maceió’s building fire safety framework is primarily governed by NBR 14432, which establishes the fire resistance requirements for structural elements, and NBR 11742, which specifies the performance criteria for doors and windows. For glazed systems, compliance demands that products provide verified Integrity (E) and Insulation (I) ratings to contain fire and limit heat transfer. Antifires’ systems are engineered to integrate seamlessly with these local codes, offering assemblies that have been tested to maintain their fire-resisting properties under standard furnace conditions, including pressure differentials of 0 ±2Pa. This ensures that in the event of a fire, the glazing will not permit the passage of flames or hot gases for the required duration.
For high-rises in the Pajuçara district, where compartmentation is critical, specifying a 28mm EI60 panel—comprising multiple layers of tempered glass and intumescent gel—provides both structural integrity and thermal insulation. The use of G.M.S. hollow steel frames and ceramic wool (density 210 kg/m³) in the perimeter seals ensures that the entire assembly performs as a unified barrier. By providing detailed test reports that correlate directly with NBR 14432’s time-based classifications, Antifires enables local engineers to confidently design passive fire protection strategies that meet the stringent requirements of the Maceió Fire Department (CBM-AL).
Selecting EI and EW Fire Rated Glass Grades for Maceió’s Tropical Climate
Selecting the appropriate fire-rated glass grade for Maceió’s tropical climate requires balancing thermal performance with environmental resilience. The high humidity and coastal salt air can affect standard materials, but Antifires’ systems are designed for durability. For projects requiring both fire safety and occupant evacuation time, EW120 (Integrity + Radiation Control) glass is ideal for corridors and lobbies, as it limits radiant heat transfer to safe levels. In contrast, EI60 or EI120 classifications are necessary for walls and doors that must prevent heat conduction, such as those enclosing stairwells or server rooms. The 10mm FPOS glass, with an Integrity of 135 minutes, is a robust choice for internal partitions where insulation is less critical, while the 26mm door glass (Integrity 89-90 min, Insulation 68 min) is specifically engineered for high-traffic door assemblies.
Technical documentation for CBM-AL inspections must demonstrate that the selected glass can maintain its rating under local conditions. Antifires provides complete assembly specifications, including the use of intumescent fire seals (20mm × 4mm) and 3-5mm expansion gaps filled with ceramic fiber, which accommodate thermal movement without compromising the seal. This ensures that the glazing system not only passes the standard fire test but also performs reliably in Maceió’s specific coastal environment, where temperature and humidity fluctuations are common.

Fire Rated Glass Applications in Maceió’s Coastal Hotels and Commercial Towers
The hospitality and commercial sectors in Maceió present unique fire safety challenges, particularly in coastal hotels and high-rise office towers. Atriums, glass facades, and interior partitions must provide fire compartmentation without obstructing views or natural light. Antifires’ 21mm FPOS glass, offering 120 minutes of integrity and 30 minutes of insulation, is an excellent choice for large-span partitions in hotel lobbies and conference centers. For external facades exposed to wind and rain, the 50mm/54mm ultra-high-performance EI120 glass provides superior thermal insulation and structural stability, tested with maximum deflection of up to 152mm toward the furnace during standard fire tests. This ensures that even under extreme thermal stress, the glass remains in place and prevents fire spread.
In commercial towers, fire-rated doors and windows must integrate with the building’s overall passive fire protection strategy. The 26mm glazed door glass is specifically designed for high-frequency use, combining a multi-layer structure (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm) to achieve both integrity and insulation. For escape routes, specifying E90 or E120 integrity-only glass in non-critical areas can provide cost-effective solutions without sacrificing safety. Antifires supports these applications with certified test data, including furnace thermocouple monitoring (Type K, 9-12 channels) and unexposed surface temperature analysis (10-55 thermocouples), ensuring that every product meets the required performance criteria for Maceió’s demanding building projects. Review the 120-minute fire-rated glass with integrity and insulation for high-performance applications.
Antifires’ Local Support and UL Certification for Maceió Building Professionals
Antifires offers comprehensive local support for Maceió building professionals, from specification guidance to project completion. All products are tested and certified to international standards, including BS 476 Part 22 and BS EN 1364-1, ensuring that the provided documentation satisfies the requirements of local fire authorities. The UL certification for key product lines, such as the EI60 and EI120 glass systems, provides an additional layer of credibility and global recognition. For Maceió-based architects, engineers, and contractors, this means access to a verified product portfolio that can be confidently specified for any project, from boutique hotels in Jaraguá to large commercial developments in Cruz das Almas.
Antifires’ technical team assists with system selection, providing detailed installation guidelines that cover frame fixing (M6/M8 anchor bolts at 300-600mm spacing), sealant application, and expansion gap management. This hands-on approach ensures that the fire-rated assemblies perform as intended, even in Maceió’s challenging coastal environment. By offering both integrity-only (E60, E90, E120) and insulation-rated (EI30, EI60, EI120) solutions, Antifires enables specifiers to tailor fire protection to the exact needs of each project.
