Fire Rated Ductwork

All of our engineers are trained in the manufacture and installation of Firemac fire rated ductwork.

Firemac FM Fire Ducts are manufactured using Firemac FM Fabric, a specially woven glass fibre cloth, produced in the UK, which is applied to steel ductwork at the point of fabrication. Firemac FM Fire Ducts are tested to British and European Standards and provide fire resistance of up to four hours, with all test evidence independently assessed by BRE and covered by Third Party Certification.

As kitchen extract ductwork should not be provided with fire dampers, fire rated ductwork should be used when immediate discharge to the outside of the building is not possible. This is because greasy deposits in extract ductwork are a fire hazard, meaning any fire can spread easily if the length of ductwork to reach the outside of the building is excessive.

Contact us if you have a project that you think might require fire rated ductwork so we can discuss your options.
