Using condition-of-the-artwork computerized producing amenities and specialised technical teams, we provide a product that balances uncompromising safety with realistic industry engineering:
A global merchandise assessment and certification on the fire resistance general performance for air flow and smoke extraction ducts is remaining accomplished by Applus+ Laboratories
It truly is most important to choose the best suited fire resisting ductwork process for its supposed software area to make certain the ductwork fire general performance satisfies the requirements of the pertinent application.
We manufacture non-coated fire rated ductwork that has been analyzed to both equally BS criteria and EN criteria.
Nevertheless, if there is a proximity of selected providers and machines mounted within the roof, then it is usually recommended.
When ductwork passes by multiple compartments, There's a possibility from the fire inside of a compartment outside the kitchen. This could cause the grease Within get more info the duct to ignite and unfold fire Within the ducts through the building.
Smoke extract ductwork is surely an crisis program and insulation should be able to Handle the exhaust temperatures. Having said that this had to be demonstrated inside a fire take a look at.
Reply the five small questions beneath to get your encouraged Durasteel system specifications. Hover above the ? icons for a short clarification.
About the roof, the smoke extract ductwork terminates for the atmosphere, as well as flashover possibility not exists generally.
Smoke is regarded as the major killer through fire outbreaks. It could unfold immediately to nearby structures which have been fairly distant from the first flash, threatening everyday living and detrimental assets. Stairwells and elevator shafts often turn into smoke logged, blocking evacuation routes and blocking firefighters as well as other rescue teams from accomplishing their crucial Employment.
The solutions adopted with the fire resistance of partitions and flooring penetrated by air flow ducts in making regulatory requirements and beneath the steering of BS 9999:
In truth, we get the job done carefully Using the BESA Advisory Panel who're responsible for designing and establishing greatest observe to the building products and services market.
This curve is based over the burning fee of the materials located generally constructing products and contents.
