Flamebar BW11: Advanced Fire-Rated Ductwork Solution for HVAC Safety

Flamebar BW11 is a lightweight, highly durable fire-rated ductwork system, engineered to meet the latest international fire safety standards. It features a specially developed water-based compound that is spray-applied onto metal duct surfaces. This premium coating contains mineral fillers within a low-permeability elastomeric binder, achieving a nominal thickness of 0.7mm. Designed to endure cellulosic fire conditions, the system offers proven fire resistance for up to 4 hours.

Ideal for various HVAC applications, Flamebar BW11 can safely handle internal gas temperatures up to 400°C, delivering up to 2 hours of fire resistance. Additionally, it enables reductions in duct gauge thickness without compromising safety or performance. The system has been tested and approved for both rectangular and circular ductwork designs, offering flexibility and compliance across diverse building layouts.

Flamebar BW11 is well-suited for smoke extraction, car park and kitchen exhaust systems, as well as stairwell pressurization.

At Rise and Shine, we further enhance duct protection with our specialized duct coatings, offering thermal insulation, condensation control, and corrosion resistance. These solutions improve energy efficiency, reduce operational costs, and ensure superior indoor air quality, all while extending the life of your HVAC systems. Learn more: rnsqatar.com
