Coated ducts can qualify for Security & Integrity criteria when subjected to full-time-temperature curve having said that it doesn't qualify for insulation standards.
Employing state-of-the-artwork computerized manufacturing services and specialized complex teams, we supply an item that balances uncompromising safety with functional field engineering:
A worldwide products evaluation and certification of your fire resistance performance for ventilation and smoke extraction ducts is being done by Applus+ Laboratories
It is primary to choose the most fitted fire resisting ductwork technique for its supposed application place to make certain that the ductwork fire general performance meets the requirements with the pertinent software.
We manufacture non-coated fire rated ductwork that has been examined to both of those BS specifications and EN benchmarks.
Nonetheless, if there is a proximity of particular companies and equipment mounted to the roof, then it is usually recommended.
Although we offer several regular methods in the Flamebar Ductwork range, our qualified design and style group can get the job done intently along with you to ascertain the optimum Alternative which maximises protection in important zones even though ensuring the challenge is available in on budget.
The devices are lightweight and space-spacing, and give as many as 4 several hours fire score in both Instructions (Kind A and kind B) in accordance with BS476: Portion 24, to provide purely natural ventilation or mechanically compelled ventilation, together with very click here hot smoke extraction within the celebration of a fire.
Remedy the five brief queries underneath to acquire your suggested Durasteel program requirements. Hover around the ? icons for a brief explanation.
Air Grasp Fire Rated Ductwork aids sustain pressurization methods and ensures compartmentation. The integrity of the duct and its means to operate have to be taken care of inside the occasion of the fire.
Smoke is regarded as the main killer all through fire outbreaks. It may distribute quickly to nearby structures that are really distant from the first flash, threatening lifestyle and detrimental assets. Stairwells and elevator shafts often develop into smoke logged, blocking evacuation routes and blocking firefighters along with other rescue teams from executing their critical Employment.
