Boa Vista Fire Rated Glass and Certified Passive Protection Systems for Roraima

In the capital of Roraima, Boa Vista, the enforcement of fire safety protocols by the Corpo de Bombeiros Militar de Roraima (CBMRR) mandates strict adherence to the ABNT NBR 11742 standard for fire-resistive glazing. This local regulation defines the required Fire Resistance Level (FRL) for egress routes, compartmentation, and building envelope systems in both high-rise residential towers and commercial plazas. Antifires supplies certified passive protection systems—including fire rated glass, doors, windows, and partitions—that are rigorously tested to meet these localized compliance requirements. By aligning product specifications with the CBMRR’s inspection criteria, Antifires ensures seamless project approval for developers and contractors operating in Boa Vista’s expanding urban landscape. For further reference on the national standard, consult the official ABNT NBR 11742 documentation.

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.

Frequently Asked Questions (FAQ)

For commercial buildings in Boa Vista, the Corpo de Bombeiros Militar de Roraima (CBMRR) mandates compliance with ABNT NBR 11742, which specifies minimum Fire Resistance Levels (FRL) based on building occupancy and height. Typically, egress routes and fire compartments require glazing with integrity (E) ratings of 30, 60, or 90 minutes, while areas like hotel corridors or hospital wards may demand insulation (I) ratings of 30 or 60 minutes. Antifires supplies certified systems—such as the 10mm FPOS with 135-minute integrity and the 28mm EI60 panel with 66-minute integrity and 64-minute insulation—that meet these mandatory ratings, ensuring full compliance with local fire codes.

Yes, Antifires provides comprehensive ABNT NBR 11742 certification documents for all fire doors, windows, and partitions used in Roraima government projects. These documents include detailed test reports from accredited laboratories, confirming that each system meets the required Fire Resistance Level (FRL) for integrity and insulation. For example, the 26mm glazed door glass is certified for 89–90 minutes of integrity and 68 minutes of insulation, while the 50mm EI120 glass delivers 120 minutes of both integrity and insulation. This documentation supports seamless approval by the CBMRR during project inspections.

Antifires ensures reliable performance under Boa Vista’s high humidity and UV exposure by using UV-stable intumescent interlayers and multi-layer laminated structures in its fire-rated glass. The 15mm FPOS and 21mm FPOS configurations incorporate tempered glass layers that resist thermal shock from intense solar radiation, while the intumescent gel remains stable under prolonged humidity. These systems are tested to maintain their integrity (E) and insulation (I) ratings—such as the 21mm FPOS achieving 120-minute integrity and 30-minute insulation—without delamination or degradation, even in Boa Vista’s challenging equatorial climate.
