ABNT NBR 11742 and PCM Fire Safety Code Compliance for Recife High-Rises
Recife’s high-rise commercial buildings, particularly those exceeding 12 stories, must comply with ABNT NBR 11742 for fire-resistant glazing assemblies and the local PCM code, which mandates passive protection in escape routes and facade openings. Antifires’ fire rated glass systems undergo third-party testing to meet these standards, ensuring that glazed elements in stairwells, corridors, and exterior walls maintain their barrier function during a fire event. The Corpo de Bombeiros Militar de Pernambuco requires documented proof of fire resistance, including integrity (E) and insulation (I) ratings, for all vertical and horizontal separations.
Our systems incorporate G.M.S. hollow steel frames with intumescent seals and ceramic wool packing, achieving tested performance such as 26mm door glass assemblies that deliver integrity for 89–90 minutes and insulation for 68 minutes. This data, verified under BS 476 Part 22 and BS EN 1634-1, provides the technical foundation for PCM submissions. For projects requiring both fire safety and natural light, consider our 60-minute fire rated glass solutions tailored for commercial interiors.
Key compliance features include:
- Third-party test reports aligned with NBR 9442 fire curve requirements.
- Certified integrity ratings from 60 to 120 minutes for critical egress paths.
- Documented insulation performance to prevent heat transfer in occupied zones.
Fire Rated Glass Grade Selection for Recife’s Tropical Climate and Thermal Stress
Recife’s tropical climate, with average relative humidity above 80% and temperatures reaching 35°C, imposes thermal stress on glazing systems that can compromise fire performance. Antifires recommends EI 60 and EI 120 rated glass with laminated intumescent interlayers designed to resist thermal shock and UV-induced degradation. The 28mm EI60 panel, for example, achieves integrity for 66 minutes and insulation for 64 minutes, making it suitable for internal compartment walls in shopping centers and hotels where temperature differentials are common.
Glass composition includes multi-layer tempered sheets bonded with fire-resistant gel that expands under heat, forming an opaque insulating barrier. For coastal projects, low-emissivity coatings reduce solar heat gain while maintaining the fire-rated assembly’s structural integrity. The 50mm EI120 ultra-high-performance glass provides both integrity and insulation for up to 120 minutes, ideal for large atrium enclosures exposed to direct sunlight. Explore our 90-minute fire rated glass for applications requiring extended protection with thermal management.
Performance considerations for Recife’s climate include:
- Resistance to salt spray corrosion through anodized or stainless steel frames.
- Expansion gap allowances (3–5 mm) filled with ceramic fiber to accommodate thermal movement.
- UV-stable interlayers that prevent yellowing and maintain optical clarity over time.
Application of Fire Rated Systems in Recife’s Mixed-Use Developments and Heritage Facades
Recife’s urban renewal projects, particularly in Boa Viagem and Recife Antigo, require fire rated glazing that balances modern safety standards with heritage preservation. Mixed-use developments combining residential towers with ground-floor retail demand systems that provide fire separation without disrupting sightlines or natural light. Antifires’ products are specified for atrium enclosures, stairwells, and historic facade retrofits, where narrow-profile fire doors and windows must meet strict fire separation distances while preserving architectural aesthetics.
For heritage facades, our 10mm FPOS glass (integrity 135 minutes, insulation 16 minutes) offers a slim profile that fits existing timber or steel frames, while 21mm FPOS assemblies (integrity 120 minutes, insulation 30 minutes) provide enhanced thermal performance for new construction. These systems use ceramic tape and intumescent seals to maintain fire resistance without bulky framing. For projects requiring both aesthetics and high insulation, review our fire rated glass doors designed for commercial and residential applications.
Application scenarios include:
- Atrium enclosures requiring EI 60 or EI 120 ratings for smoke management.
- Stairwell pressurization zones with glazed partitions that maintain compartmentation.
- Historic window retrofits using narrow-profile fire-rated assemblies that meet local preservation guidelines.
Why Recife Contractors Choose Antifires for Certified Fire Protection and Logistics
Recife-based project managers and contractors benefit from Antifires’ comprehensive support, including full ABNT certification documentation and localized technical assistance in Portuguese. Our direct import logistics through the Port of Suape reduce lead times by up to 30%, ensuring that fire-rated glass, doors, and partitions arrive on schedule for fast-track hotel and office projects. Each shipment includes test reports, installation manuals, and compliance certificates aligned with PCM inspection requirements.
Antifires offers on-site sample testing for EI ratings, allowing contractors to verify performance under local conditions before full-scale installation. Our technical team provides guidance on frame selection, sealant application, and anchor bolt spacing (M6/M8 at 300–600 mm intervals) to meet AS1530.4 and BS EN 1364-1 standards. For projects requiring both fire safety and logistical efficiency, explore our fire rated glass partitions designed for rapid deployment.
Key advantages for Recife contractors include:
- Portuguese-language documentation for seamless regulatory submissions.
- Reduced shipping times via Suape port compared to southern Brazilian terminals.
- Technical support for installation, including expansion gap management and ceramic wool packing.
