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.

It can confidently be specified and installed for:

• Smoke extract
• Car park extract
• Kitchen extract
• Stair pressurisation systems
