So, the fire resisting duct desires to keep up i.e., not compromise the fire resistance from the wall or ground through which it penetrates. The overall performance of the fire resisting duct which penetrates a fire resisting/separating factor demands careful thought by specifiers and controlling authorities. The typical intervals of steadiness and integrity need to in all instances be a minimum of equivalent to Individuals required for that penetrated element of development.
Using condition-of-the-artwork computerized producing facilities and specialized specialized teams, we supply an item that balances uncompromising safety with practical area engineering:
No matter if it's the fire protection of present metallic ducting, or the forming of new independent self-supporting fire rated ductwork, Thameside Fire Stopping Ltd, supply an unparalleled provider in the development and array of available supplies to meet the large requirements demanded, offering approximately four-hour fire score and substantial levels of pressurisation and insulation.
It is actually most significant to select the best suited fire resisting ductwork procedure for its intended software space to make certain that the ductwork fire functionality satisfies the requirements of your relevant application.
We manufacture non-coated fire rated ductwork that has been analyzed to both of those BS benchmarks and EN benchmarks.
Even so, when there is a proximity of specified services and products mounted over the roof, then it is recommended.
When ductwork passes by means of many compartments, there is a threat from the fire in a very compartment outside the house the kitchen area. This may cause the grease Within the duct to ignite and unfold fire Within the ducts all over the setting up.
Smoke extract ductwork can be an emergency procedure and insulation will be able to Command the exhaust temperatures. Nonetheless this needed to be confirmed in a fire test.
The techniques are made bespoke so that you can attain the necessary cross-sectional place of airflow at the required tension and will accommodate foot visitors inside to allow for maintenance accessibility.
Only company in the center-East with lightest smoke-extract duct examined beneath full time-temperature curve for 120min
This is completely Erroneous and is taken into account detrimental to setting up get more info safety. Should the ductwork loses security / integrity, Insulation will fall short as it is going to transfer Along with the collapse of ducts.
Integrity-only (E)Fire compartmentation to stop the flames or hot gases from bodily passing through the fire aspect towards the non-fire side as a result of holes, gaps, cracks or any other sorts of openings to the denoted duration
Fire dampers are applied to keep up compartmentation within the event of fire, to limit spread of fire from a person site to another to prevent migration of fire from the constructing.
Kitchen area extract ductwork poses a selected risk mainly because of the existence of combustible grease lining (cooking oil fumes turn into grease) Within the ductwork.
