For general ventilation use, ductwork needs different fire rated requirements.

This ductwork can either be used for air supply or extraction and it must be fire rated between where it passes through a fire compartment through an escape corridor. There are also requirements that the ductwork meets type A fire outside and type B fire criteria.

Flameshield Fireduct satisfies all of the above with full compliance and without the need for an outer coating, which can be damaged in transit.
