Coated ducts can qualify for Steadiness & Integrity criteria when exposed to full time-temperature curve however it does not qualify for insulation conditions.
Using condition-of-the-artwork computerized manufacturing facilities and specialised technical teams, we deliver a product that balances uncompromising safety with simple field engineering:
Occasionally contractors wrap typical ventilation ducts with Rockwool or non-combustible insulation of any thickness/density.
Essential Properties of Fire Rated Ductwork Fire rated ductwork generally should go through compartment partitions or floors that should have a prescribed fire resistance period regarding the load bearing ability, integrity and insulation standards, for durations of thirty to 240 minutes. This is a prerequisite that where by these compartment partitions/flooring are penetrated by HVAC ducts or other making companies, the fire overall performance conditions to the penetrated wall or floor are maintained, this kind of that fire in one compartment may well not unfold to other places.
Ductform is among the United kingdom’s foremost producers of fire rated ductwork for any tasks and from several fire resistances for as much as 2 hrs.
Our method option of FIREMAC 120 is usually a fresh idea for fire rated ductwork which satisfies all the factors to satisfy all the current Building Polices (England, Scotland and Wales) for fire resistance.
Our motivation to safety is backed by ongoing testing in addition to a proactive approach to on-internet site quality Management.
By insulating smoke extraction ducts, we have been restricting the danger by avoiding flashovers which may be induced when transporting scorching gases in the spot of fire to your ambiance. Any type of secondary fire can be encountered by firefighters effortlessly on account of elimination of incredibly hot gases from the location of fire.
Solution the five quick concerns underneath to receive your advisable Durasteel system specifications. Hover in excess of the ? icons for a short rationalization.
Within the roof, the smoke extract ductwork terminates towards the ambiance, as well as flashover possibility no more exists typically.
This is completely Mistaken and is considered harmful to constructing safety. In the event the ductwork loses stability / integrity, Insulation will are unsuccessful as it's going to go While using the collapse of ducts.
Duct employed for the extraction of smoke in the event of fire and built to give a degree of fire resistance
Should you be linked to the provision of fire protection, at any amount, then you share liability and responsibility for its usefulness and operation when it’s essential in fire. This is often why you need to be sure that the ducting that you are fitting is nearly The work.
This curve is predicated within the burning level on the supplies observed check here generally constructing supplies and contents.
