Our Flamebar systems address complex design challenges in high-rise residential, hospitality, healthcare, and industrial projects, with solutions tested to 4 hours at 2000F for fire safety compliance. We specialize in horizontal and vertical fire-rated duct systems, grease ducts, and A2L refrigerant enclosures, offering value-engineered designs that reduce installation costs by up to 40% while minimizing spatial requirements. Our team provides technical support from schematic design through final inspection, ensuring code compliance and operational efficiency. Headquartered in Warren, Michigan, we deliver nationwide with just-in-time logistics and field expertise in fire safety engineering.

With over 1,000 completed projects spanning millions of square feet, we combine rigorous laboratory testing with practical construction knowledge to simplify coordination and reduce project timelines. Our commitment to innovation is demonstrated through patented system designs that maximize gross leasable area while maintaining structural integrity during fire events. We maintain direct relationships with AHJs to ensure local jurisdiction acceptance and provide training programs for proper installation techniques. Our process controls guarantee material consistency, and our technical staff collaborates on budget guidance, detailing, and post-installation verification.
