Flamebar BW11

Flamebar BW11

Flamebar BW11 fire rated ductwork is fabricated from galvanised sheet steel to an enhanced standard. It is then degreased and sprayed with a coating using a specially formulated water based compound. The coating contains selected mineral filters in a low permeablility elastomeric binder to a thickness of 0.7mm minimum to give a finished product which has been successfully tested for international use under Cellulosic Fire Conditions for 4 hours duration.

The unique BW11 coating has a number of distinct benefits:

The provision of in excess of 2 hours insulation when handling internal gas temperatures of 400°C

A reduction in base duct construction thickness or gauge

Reduction in duct reinforcement

The system has been successfully tested for international use, under cellulosic fire conditions, to give in excess of four hours fire resistance in the event of a fire.
