What is Flamebar duct?
Flamebar® is a fire-rated duct system which utilizes pre-fabricated ductwork with a fire resistant coating, Flamebar® BW11, in lieu of typical fire wrap. This proprietary coating allows systems to meet and exceed two-hour and four-hour test standards.
What is fire rated ductwork?
Fire rated ductwork improves the safe operation of heating, ventilation and air conditioning (HVAC) systems by minimising the chance of fire spread. Effective fire resilient insulation acts as a barrier between ducts, to slow down or prevent the passage of flames and smoke around the building.
Where is fire-rated ductwork required?
Fire-rated ductworks are required to conduct the smoke outside the building, even using fan assisted systems. If a smoke extraction ductwork is wholly contained within a fire compartment, it must be capable of at least resisting the anticipated smoke temperatures generated during the development of a fire.
What is duct system?
What is a duct system? The ventilation system in a building consists of air moving devices such as fans and blowers and a network of ducts to exhaust the contaminated indoor air and to bring in air from the outside of the building. Ducts are channels, tubes, or pipes that carry moving air.
Does standard ductwork have a fire rating?
Regular ventilation ducts offer no fire protection, unless they have been designed and tested and classified to have achieved an E rating. It’s a system! And it works. It delivers the highest possible protection against fire.
Does smoke extract ductwork need to be fire rated?
A general rule, however, is that any ductwork system that is intended to operate, or has a special use, under a fire condition and therefore cannot use fire dampers, will require a fire resistance rating.
Which are the types of duct?
4 Types of Ducts for Central AC
- Fiberglass Lined Air Ducts. Whether on the interior or exterior of the system, a fiberglass lining insulates the ducts to prevent heat loss or condensation.
- Fiberboard Air Ducts.
- Sheet Metal Air Ducts.
- Flexible Air Ducts.
What are ducts used for?
Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, supply air, return air, and exhaust air. Ducts commonly also deliver ventilation air as part of the supply air.
What do you need to know about flamebar duct systems?
What is Flamebar®? Flamebar® is a fire-rated duct system which utilizes pre-fabricated ductwork with a fire resistant coating, Flamebar® BW11, in lieu of typical fire wrap. This proprietary coating allows systems to meet and exceed two-hour and four-hour test standards.
What kind of ductwork does BCH use?
Flamebar® duct systems satisfy all four requirements and have been incorporated into local high-rise projects by BCH. What is Flamebar®? Flamebar® is a fire-rated duct system which utilizes pre-fabricated ductwork with a fire resistant coating, Flamebar® BW11, in lieu of typical fire wrap.
What kind of binder is in flamebar firespray?
The premium coating contains selected mineral fillers in a low permeability elastomeric binder to a nominal thickness of 0.7mm to give a finished product, which has been successfully tested for international use under cellulosic fire conditions for up to and including 4 hours duration.
