The program is a unique patented method applying a versatile material that's bonded the two physically and mechanically towards the ductwork throughout the manufacture method.
Examined in horizontal as well as vertical orientation independently below cellulosic (standard time Vs. temperature curve) fire problems and effectively obtained in excess of 120 minutes of fire resistance for integrity and security of
A global solution assessment and certification in the fire resistance functionality for ventilation and smoke extraction ducts is becoming completed by Applus+ Laboratories
Fundamental Properties of Fire Rated Ductwork Fire rated ductwork commonly has to go through compartment walls or flooring that can have a prescribed fire resistance period with regard to the load bearing capability, integrity and insulation conditions, for durations of 30 to 240 minutes. It is just a requirement that wherever these compartment walls/flooring are penetrated by HVAC ducts or other building expert services, the fire overall performance conditions for the penetrated wall or flooring are managed, this sort of that fire in a single compartment may not unfold to other parts.
Sure - approximately 10kN/m²Very low blast ranking of nearly 10kN/m² (10kPa, one.45psi) producing average harm to residences (Home windows and doorways blown out and critical harm to roofs) and accidents to men and women from traveling glass and debris
Our procedure decision of FIREMAC one hundred twenty is really a new notion for fire rated ductwork which satisfies all the factors to fulfill all the current Setting up Rules (England, Scotland and Wales) for fire resistance.
While we provide numerous typical options in the Flamebar Ductwork range, our specialist structure group can get the job done closely with you to find out the ideal Alternative which maximises protection in vital zones although making sure the project comes in on funds.
The devices are lightweight and House-spacing, and present around four hrs fire rating in both directions (Variety A and kind B) in accordance with BS476: Part 24, to deliver purely natural air flow or mechanically pressured ventilation, including warm smoke extraction from the function of a fire.
Respond to the 5 quick issues below to obtain your encouraged Durasteel method technical specs. Hover around the ? icons for a short explanation.
About the roof, the smoke extract ductwork terminates for the atmosphere, and the flashover hazard no more exists usually.
Created from exceptional top quality Galvanised steel, our Flamebar Fire Rated Ductwork remedies are actually developed to meet essentially the most stringent requirements and became the popular Option by lots of specifiers and builders.
Integrity-only (E)Fire compartmentation to stop the flames or hot gases from bodily passing with the fire aspect for the non-fire side as a result of holes, gaps, cracks or any other sorts of openings to the denoted duration
When you are associated with the provision of fire protection, at any level, Then you definately share liability and obligation for its usefulness and operation when it’s desired in fire. That is why you'll need to ensure that the ducting you might be fitting is nearly The task.
Integrity & Insulation (EI)Fire compartmentation to stop the flames or scorching gases from fire resisting ductwork physically passing in the fire side to the non-fire side via holes, gaps, cracks or any other types of openings and limit the increase in floor temperature to the non-fire aspect to the denoted duration
