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.

Thor Duct® is tested to EN1366-1, horizontal and vertical, fire types A and B, classified EN13501-3, product standard prEN15871. Thor Duct® has also tested to EN1366-1 under the standard EN15882-1, allowing for a maximum size of 2500x1250 mm.

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.
