The method is a unique patented system using a versatile material that's bonded equally physically and mechanically for the ductwork throughout the manufacture procedure.
Examined in horizontal as well as vertical orientation individually less than cellulosic (common time Vs. temperature curve) fire conditions and productively accomplished in excess of 120 minutes of fire resistance for integrity and balance of
Occasionally contractors wrap regular ventilation ducts with Rockwool or non-combustible insulation of any thickness/density.
Any extra services linked to fire ductwork supports may possibly include unknown load bearing components, which in case of fire may effects The soundness from the ductwork just when it is necessary most.
We manufacture non-coated fire rated ductwork which has been examined to the two BS expectations and EN expectations.
Nevertheless, when there is a proximity of certain expert services and gear mounted to the roof, then it is recommended.
Although we provide several conventional options in the Flamebar Ductwork range, our skilled structure group can get the job done closely with you to find out the ideal solution which maximises protection in vital zones although making sure the project comes in on funds.
The techniques are light-weight and Place-spacing, and provide up to four hours fire score in both equally directions (Style A and sort B) in accordance with BS476: Part 24, to offer organic air flow or mechanically forced air flow, such as warm smoke extraction while in the event of a fire.
The units are designed bespoke to be able to accomplish the essential cross-sectional place of airflow at the required tension and will accommodate foot targeted visitors inside of to permit for routine maintenance obtain.
Around the roof, the smoke extract ductwork terminates to the ambiance, as well as the flashover danger now not exists commonly.
Smoke is regarded as the main killer through fire outbreaks. It could unfold immediately to nearby structures that happen to be fairly remote from the initial flash, threatening everyday living and damaging house. Stairwells and elevator shafts routinely turn out to be smoke logged, blocking evacuation routes and avoiding firefighters and various rescue teams from carrying out their essential Careers.
The solutions adopted with the fire resistance of partitions and flooring penetrated by ventilation ducts in constructing regulatory requirements and beneath the assistance of BS 9999:
Air get more info Master Smoke Extract ductwork is actually a vital element of a fire approach, by properly channeling smoke out from the constructing.
This curve is predicated on the burning charge with the products discovered on the whole setting up materials and contents.
