The technique is a singular patented program making use of a flexible fabric that's bonded equally physically and mechanically towards the ductwork throughout the manufacture process.
Wall penetration design is strictly as per exam problems. Manufacturers’ will present needed coaching and guidelines to set up it.
From time to time contractors wrap regular air flow ducts with Rockwool or non-combustible insulation of any thickness/density.
Any added solutions connected to fire ductwork supports could insert unfamiliar load bearing variables, which in the event of fire may well impact The soundness with the ductwork just when it is necessary most.
We manufacture non-coated fire rated ductwork which has been examined to the two BS standards and EN expectations.
Having said that, if there is a proximity of sure expert services and tools mounted over the roof, then it is suggested.
