Coated ducts can qualify for Security & Integrity standards when exposed to full time-temperature curve however it doesn't qualify for insulation standards.
Employing point out-of-the-art computerized production amenities and specialized technological teams, we produce a product that balances uncompromising safety with simple discipline engineering:
A world solution evaluation and certification in the fire resistance performance for air flow and smoke extraction ducts is remaining performed by Applus+ Laboratories
It truly is most significant to select the most fitted fire resisting ductwork method for its meant software space making sure that the ductwork fire overall performance fulfills the requirements of your pertinent software.
We manufacture non-coated fire rated ductwork that's been examined to the two BS specifications and EN specifications.
Having said that, if there is a proximity of sure providers and machines mounted within the roof, then it is usually recommended.
When ductwork passes by way of various compartments, there is a threat from the fire in a very compartment outside the house the kitchen area. This may cause the grease Within the duct to ignite and unfold fire Within the ducts all over the setting up.
The systems are light-weight and Area-spacing, and give as many as 4 several hours fire rating in both Instructions (Kind A and kind B) in accordance with BS476: Element 24, to deliver normal ventilation or mechanically pressured air flow, like scorching smoke extraction during the function of the fire.
Response the five shorter concerns under to get your proposed Durasteel system specs. Hover in excess of the ? icons for a short rationalization.
Air Grasp Fire Rated Ductwork aids sustain pressurization methods and ensures compartmentation. The integrity of your duct and its means to operate has to be maintained during the celebration of a fire.
Ducts ought to be supported strictly as per brands requirements and set up tips. Support technique assessment has to be based on examination overall performance.
Duct employed for the extraction of smoke in case of fire and designed to give a degree of fire resistance
If you're linked to the provision of fire protection, at any degree, Then you definitely share legal responsibility and duty for its usefulness and Procedure when it’s necessary in fire. This is why you require to make certain that the ducting that you are fitting is approximately the job.
Integrity & Insulation (EI)Fire compartmentation to stop get more info the flames or scorching gases from physically passing in the fire side towards the non-fire side via holes, gaps, cracks or any other types of openings and Restrict the increase in floor temperature about the non-fire aspect for your denoted duration
