The Passive Fire Protection Handbook: Chapter 6 - Fire Rated Ductwork

The relative complexity of any ductwork system which is passing through different fire compartments and the relevance of the system’s function in ambient and fire conditions can make the selection of a suitable ductwork system difficult. This section of the handbook aims to give guidance on the fire performance requirements of ductwork and offers a wide range of solutions for proprietary “off the shelf” fire rated ductwork, the protection of steel ductwork and for self-supporting systems using Promat PROMATECT®-L500.
