Firespray manufactures the Flamebar range of passive fire-resistant products, including the highly successful Flamebar BW11 fire-resistant ductwork system.
FLAMEBAR BW11 fire-duct is constructed from galvanized sheet steel, manufactured to the SMACNA standard, then degreased and factory fire sprayed with FLAMEBAR BW11, a specially formulated water-based compound. The finished product contains selected mineral filters in a low permeability elastomeric binder, to a thickness of approximately 1mm, and has been successfully tested for international use under cellulosic fire conditions - in excess of four hours duration. FLAMEBAR BW11 ductwork is produced in sections and assembled on site utilizing tested fireproof gaskets/sealants.
The unique properties of FLAMEBAR BW11 has enabled the design of a low density, highly durable material, which accommodates induced stress arising from extreme and varying conditions; including climatic moisture, structural loading variations and the effect of thermal-shock during a fire.
The systems have been tested and accredited by UL, Intertek, ULC, Southwest Research Institute and Grease Duct, listed in accordance with ASTM E-2336 and also classified by UL to ISO 6944 (1985) up to a temperature of 2,071°F (1,133°C.)
