Tested in horizontal as well as vertical orientation individually beneath cellulosic (standard time Vs. temperature curve) fire conditions and properly reached more than a hundred and twenty minutes of fire resistance for integrity and stability of
Irrespective of whether it be the fire protection of existing metal ducting, or perhaps the forming of recent unbiased self-supporting fire rated ductwork, Thameside Fire Halting Ltd, provide an unparalleled provider in the development and array of available components to satisfy the superior requirements demanded, furnishing up to 4-hour fire rating and higher levels of pressurisation and insulation.
Any further providers connected to fire ductwork supports might include unidentified load bearing aspects, which in the event of fire may perhaps effects the stability in the ductwork just when it is required most.
We manufacture non-coated fire rated ductwork that has been tested to equally BS benchmarks and EN requirements.
Together with the ductwork we offer bespoke guidance units and will almost always be accessible to respond to any thoughts which will crop up.
Our motivation to safety is backed by constant fire resisting ductwork tests plus a proactive approach to on-web-site high quality Command.

As a totally dry set up consisting of angle framework with 9.5mm Durasteel sheets mounted to the surface, the techniques might be re-worked on internet site to support hard internet site ailments and present one of a kind flexibility that other prefabricated duct systems cannot.
Ducts have to be supported strictly According to producers technical specs and installation guidelines. Assist method evaluation should be dependant on check performance.
The approaches adopted for that fire resistance of partitions and flooring penetrated by air flow ducts in making regulatory requirements and underneath the guidance of BS 9999:
Indeed, we get the job done closely While using the BESA Advisory Panel who're responsible for planning and creating finest practice to the building expert services market.
This curve is based about the burning level from the components uncovered normally constructing materials and contents.
