Aligning with Boa Vista’s State Fire Code and ABNT NBR 11742 Compliance Requirements
Boa Vista’s building code, enforced by the CBMRR, requires that all glazed elements in fire-rated assemblies achieve a minimum Fire Resistance Level (FRL) as specified in ABNT NBR 11742. This standard classifies fire-resistive glazing based on integrity (E) and insulation (I) performance. Antifires offers a comprehensive range of products that meet these criteria, including 30-, 60-, 90-, and 120-minute rated systems. For example, the 10mm FPOS configuration—comprising 3mm float glass + 4mm fire gel + 3mm float glass—achieves integrity for 135 minutes, while the 28mm EI60 panel delivers 66 minutes of integrity and 64 minutes of insulation. These certified ratings directly support compliance with the CBMRR’s requirements for egress corridors and fire compartments in Boa Vista’s commercial and residential towers. Contractors can confidently specify fire rated glass solutions that align with both national standards and local inspection protocols.
Specifying Fire Rated Glass Integrity and Insulation Ratings for Boa Vista’s Tropical Climate
Boa Vista’s equatorial climate, characterized by intense solar radiation and frequent thunderstorms, presents unique challenges for fire-rated glazing systems. Antifires addresses these conditions with laminated fire rated glass that carries E (integrity) and EW (integrity with limited radiation) classifications per NBR 11742. The 15mm FPOS structure, featuring multi-layer tempered glass with intumescent gel, provides integrity up to 132 minutes and insulation for 33–34 minutes, while resisting thermal shock from rapid temperature changes. For applications requiring enhanced radiation control, the 21mm FPOS composite insulated glass offers 120 minutes of integrity and 30 minutes of insulation. These systems incorporate UV-stable interlayers that prevent delamination under prolonged sun exposure, making them ideal for curtain walls and storefronts in Boa Vista’s mixed-use developments. The 50mm and 54mm ultra-high-performance glass units deliver EI120 ratings, ensuring reliable performance in the region’s demanding environmental conditions.
Addressing Fireproofing Needs in Boa Vista’s Government Buildings and Hotel Construction Sector
Boa Vista’s expanding administrative district and tourism-driven hotel construction sector demand fire-rated assemblies that comply with CBMRR exit width and smoke containment rules. Antifires supplies 60-minute EI-rated fire windows for hotel corridors and fire-rated glass walls for public agency lobbies, effectively reducing passive fire spread while maintaining daylighting in the equatorial climate. The 26mm glazed door glass—a 5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm configuration—achieves 89–90 minutes of integrity and 68 minutes of insulation, meeting the stringent requirements for egress doors in government buildings. These systems are installed using G.M.S. hollow steel frames with 3mm–6mm ceramic wool and 20mm × 4mm intumescent fire seals, ensuring smoke-tight performance that aligns with CBMRR’s compartmentation standards. Antifires also provides fire rated glass solutions for large-scale lobby areas, combining fire safety with architectural transparency.
