Coated ducts can qualify for Stability & Integrity criteria when subjected to full time-temperature curve even so it does not qualify for insulation criteria.
Tested in horizontal and vertical orientation separately less than cellulosic (normal time Vs. temperature curve) fire disorders and efficiently achieved in excess of a hundred and twenty minutes of fire resistance for integrity and balance of
A global item assessment and certification from the fire resistance efficiency for ventilation and smoke extraction ducts is remaining finished by Applus+ Laboratories
Any supplemental expert services connected to fire ductwork supports might add not known load bearing variables, which in case of fire may perhaps impression the stability of the ductwork just when it is required most.
Ductform has become the United kingdom’s major companies of fire rated ductwork for just about any projects and from many fire resistances for nearly two hours.
Together with the ductwork we offer bespoke help methods and will almost always be accessible to reply any questions which will occur.
Our motivation to safety is backed by continual testing and also a proactive approach to on-internet site top quality control.
Metallic clad methods provide some protection from blast hurt or vandalism, and the ability to be accessed for foreseeable future solutions alterations.
The methods are made bespoke in order to accomplish the expected cross-sectional space of airflow at the required pressure and may accommodate foot targeted traffic within to permit for servicing obtain.
Only company in the center-East with lightest smoke-extract duct tested less than full time-temperature curve for 120min
Manufactured from outstanding excellent Galvanised metal, our Flamebar Fire Rated Ductwork alternatives have been created to satisfy probably the most stringent specs and became the popular Option by lots of specifiers and developers.
Insulation within the ducts while in the kitchen supply no protection. A fire within a industrial kitchen will probably be subject to the kitchen area suppression units and compartmentation framework.
In truth, we perform intently Together read more with the BESA Advisory Panel who are accountable for coming up with and creating finest apply to the building companies industry.
Integrity & Insulation (EI)Fire compartmentation to prevent the flames or very hot gases from bodily passing through the fire aspect on the non-fire aspect by way of holes, gaps, cracks or any other kinds of openings and limit the rise in surface temperature around the non-fire side with the denoted period
