Coated ducts can qualify for Security & Integrity requirements when subjected to full-time-temperature curve on the other hand it does not qualify for insulation criteria.
Utilizing point out-of-the-art computerized producing facilities and specialized complex teams, we provide an item that balances uncompromising safety with sensible subject engineering:
Irrespective of whether or not it's the fire protection of existing metallic ducting, or even the forming of recent independent self-supporting fire rated ductwork, Thameside Fire Halting Ltd, supply an unparalleled support in the development and choice of offered elements to fulfill the high requirements demanded, supplying around 4-hour fire score and substantial amounts of pressurisation and insulation.
Any supplemental solutions connected to fire ductwork supports could incorporate unfamiliar load bearing elements, which in the event of fire may perhaps effects The steadiness on the ductwork just when it is required most.
We manufacture non-coated fire rated ductwork which has been examined to equally BS expectations and EN expectations.
However, if there is a proximity of sure companies and equipment mounted to the roof, then it is recommended.
When ductwork passes via several compartments, You will find a risk from a fire within a compartment exterior the kitchen area. This could potentially cause the grease inside the duct to ignite and spread fire inside the ducts all through the making.
