Thor Duct®
Fire Ductwork
Thor Duct® Fire Ductwork is suitable for applications where Integrity (E) is required for period of up to 120 minutes. For Insulation (I) requirements protection is also provided using the tested insulation package for periods up to 120 minutes. Thor Duct® is ideal for use in a pressurisation system, and where the use of fire dampers is not a viable option. Thor Duct® will maintain the compartmentation rating that fire dampers would otherwise provide.
Passive ducts, specified as fire ducts, are tested to EN1366-1. Thor Duct® Fire Ductwork meets all the current regulations and is the most suitable choice. Thor Duct® Fire Ductwork has been tested with insulation, and is classified to standard EN13501-3.
Where fire resisting ductwork is required, we recommend that both the (E) Integrity and (I) Insulation performance of a fire compartment barrier are maintained.
Thor Duct® is suitable for use in protected lobbies and escape routes meeting the requirements of BS9999:2017
Thor Duct® Fire Ductwork is a non-coated system, suitable for installation in multi-compartment, single compartment, stud wall, solid wall, and aerated concrete floors. A comprehensive set of support bracketry is provided. Penetration seals guidance is provided with detailed drawings. Thor Duct® is your sustainable partner, actively reducing the amount of energy required in construction, creating a low carbon footprint and a 99% recyclable product.
