The Passive Fire Protection Handbook: Chapter 6 - Fire Rated Ductwork
Technical data sheet
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.
