The system is a unique patented method making use of a flexible cloth which is bonded both bodily and mechanically into the ductwork in the manufacture method.
Analyzed in horizontal as well as vertical orientation independently under cellulosic (regular time Vs. temperature curve) fire conditions and successfully accomplished above one hundred twenty minutes of fire resistance for integrity and balance of
Sometimes contractors wrap regular ventilation ducts with Rockwool or non-combustible insulation of any thickness/density.
Fundamental Traits of Fire Rated Ductwork Fire rated ductwork normally should pass through compartment walls or flooring that should have a prescribed fire resistance interval with regard to the load bearing capability, integrity and insulation requirements, for durations of thirty to 240 minutes. It is just a prerequisite that exactly where these compartment partitions/floors are penetrated by HVAC ducts or other building products and services, the fire functionality requirements for your penetrated wall or floor are preserved, this sort of that fire in a single compartment may not distribute to other places.
Of course - up to 10kN/m²Reduced blast rating of approximately 10kN/m² (10kPa, one.45psi) creating reasonable damage to homes (windows and doors blown out and critical harm to roofs) and injuries to individuals from flying glass and debris
Along with the ductwork we offer bespoke support systems and will almost always be accessible to response any inquiries that will come up.
Professional Oversight: We provide periodic on-web-site inspections and training by our specialized crew to be certain set up aligns with Qualified standards.
By insulating smoke extraction ducts, we are limiting the risk by preventing flashovers which can be prompted when transporting incredibly hot gases through the area of fire for read more the atmosphere. Virtually any secondary fire is often encountered by firefighters quickly on account of elimination of hot gases within the position of fire.

Air Grasp Fire Rated Ductwork assists sustain pressurization methods and ensures compartmentation. The integrity of your duct and its means to operate has to be maintained in the party of a fire.
Produced from excellent high-quality Galvanised metal, our Flamebar Fire Rated Ductwork solutions have already been formulated to fulfill the most stringent specifications and are becoming the preferred Resolution by quite a few 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 via holes, gaps, cracks or any other sorts of openings for that denoted length
Fire dampers are utilized to maintain compartmentation during the celebration of fire, to restrict distribute of fire from just one spot to another to circumvent migration of fire from the creating.
Kitchen extract ductwork poses a specific danger a result of the existence of combustible grease lining (cooking oil fumes develop into grease) In the ductwork.
