MAXIMIZE SAFETY AND ENSURE COMPLIANCE WITH FLAMEBAR

Regulatory compliance is a critical concern in modern construction. Conquest is your trusted partner to assist in value engineering designs and provide a proven solution that meets the highest safety standards. By delivering superior fire resistance, Flamebar ensures that projects adhere to code requirements while enhancing overall building safety.
Regulatory compliance in fire safety isn’t just about checking boxes – it’s about ensuring real-world protection.
Flamebar goes beyond traditional solutions by providing up to 4 hours of fire resistance, both inside and outside the duct, meeting the most demanding safety requirements where other systems fall short. Superior to outside-only protection, this dual level of protection ensures that critical HVAC systems remain operational during a fire, enabling occupants to evacuate safely and limiting property damage.
Where Other Solutions Fall Short
Traditional solutions relying on fire wrap or built enclosures offer incomplete protection, with effective resistance only from the outside of the duct – not protection from both the inside and outside to meet building code symmetry requirements. They also require additional structural modifications to achieve similar fire ratings and are more complex and time-consuming to install, increasing costs and project timelines.
By contrast, Flamebar factory-applied coatings are laboratory tested and listed, creating a seamless protective barrier that meets stringent compliance standards like ASTM E119, ISO 6944, ASTM E2816, and ASTM E814.
With Flamebar, builders, engineers, and facility owners can be confident that fire-rated systems meet fire safety regulations and simplify installation, saving time and assuring compliant life safety systems.

TESTED FOR FIRE-RATED DUCT CONDITIONS
Flamebar is engineered to comply with the ASTM E119 standard, the widely recognized benchmark for fire resistance in architectural assemblies. ASTM E119 evaluates the ability of materials to withstand extreme heat and prevent fire penetration for a specified duration. Flamebar meets these requirements, ensuring it functions as an integral part of a building’s passive fire protection system.
In addition to ASTM E119, Flamebar undergoes rigorous testing for fire-rated duct applications, ensuring compliance with:
- ISO 6944 – A standard that assesses the fire resistance of ventilation ducts under realistic fire conditions. This ensures Flamebar maintains its integrity and performance in both fire-exposed and fire-protected scenarios.
- ASTM E2816 – A specialized test method that evaluates the fire resistance of HVAC duct enclosures, validating their ability to contain and prevent the spread of fire within duct systems.
By meeting these stringent standards, Flamebar provides reliable, tested fire protection that satisfies regulatory requirements while supporting a safer built environment.
