Fire Protection of Ductworks


Self-supporting Ducts

The relative complexity of any ductwork system passing through different fire compartments and the relevance of the system’s function in ambient as well as fire conditions can make the selection of a suitable ductwork system difficult.

Promat provides guidance on fire performance requirements and a wide range of solutions for protecting ductwork and other self supporting systems.

The following points are some of the factors which should be considered when determining the correct specification to ensure a ductwork system will provide the required fire performance.

  • Required fire exposure
  • Required fire performance
  • Supporting structure
  • Hanger support
  • Steel ductwork
  • Penetrations through walls & floors
  • Movement joints
  • Air flow & leakage
  • Ductwork functions
  • Other requirements
