The program is a unique patented system using a versatile material which can be bonded both equally physically and mechanically towards the ductwork throughout the manufacture process.
Analyzed in horizontal and also vertical orientation separately under cellulosic (standard time Vs. temperature curve) fire conditions and correctly reached above 120 minutes of fire resistance for integrity and steadiness of
A world product or service evaluation and certification with the fire resistance general performance for air flow and smoke extraction ducts is remaining finished by Applus+ Laboratories
Any extra services connected to fire ductwork supports may possibly insert mysterious load bearing aspects, which in case of fire may perhaps impression The soundness from the ductwork just when it is necessary most.
We manufacture non-coated fire rated ductwork that has been tested to both BS requirements and EN specifications.
Having said that, if there is a proximity of selected companies and devices mounted over the roof, then it is recommended.
When ductwork passes by means of many compartments, there is a danger from a fire in the compartment exterior the kitchen area. This can cause the grease inside the duct to ignite and spread fire inside the ducts all through the constructing.
Smoke extract ductwork is really an emergency process and insulation will be able to Regulate the exhaust temperatures. Nevertheless this needed to be proven in the fire test.
Remedy the five short queries underneath to acquire your proposed Durasteel method specs. Hover in excess of the ? icons for a quick rationalization.
Around the roof, the smoke extract ductwork terminates to the ambiance, along with the flashover threat no longer exists commonly.
Smoke is acknowledged as the foremost killer in the course of fire outbreaks. It may possibly spread speedily to close by buildings which might be pretty remote from the initial flash, threatening lifetime and damaging home. Stairwells and elevator shafts commonly become smoke logged, blocking evacuation routes and avoiding firefighters and various rescue groups from performing their essential Work opportunities.
The techniques followed for the fire resistance of walls and flooring penetrated by air flow ducts in setting up regulatory requirements and underneath the steering of BS 9999:
In truth, we perform intently With all the BESA Advisory Panel who will be liable for building and building finest apply for that building companies field.
Integrity & Insulation (EI)Fire compartmentation to halt the flames or incredibly hot gases from bodily passing with the fire facet to your non-fire side fire safety ductwork via holes, gaps, cracks or any other types of openings and Restrict the increase in floor temperature about the non-fire aspect to the denoted duration
