Selecting the fire protection duct
5 Selecting the fire protection duct
Depending on the required classification, fire protection ducts with differ-
ent wall thicknesses and mounting systems are used.
5 1
Fire protection duct for direct wall/ceiling mounting
Direct wall and ceiling mounting is particularly appropriate when no
pipes need to be refitted, buildings refurbished or surface refinement is
required, in order to integrate the duct visually into the appearance of the
room. The duct covers are screwed to the duct trough.

Fire protection duct for mounting with a support system
Mounting with a support system is particularly useful if obstacles such as
heating, ventilation or water pipes or joists must be refitted. The support
system can consist of
– wall supports,
– suspended supports with support brackets and threaded rods
– or threaded rods and support rails.
With wall supports, it is possible to compensate for larger unevenness-
es in walls or avoid vertical cables or pipelines. Support systems with a
suspended support and support bracket are easier to fill with cables. If
suspended with threaded rods, a smaller mounting area under the ceil-
ing is required. The selection of the support system is aligned to the local
conditions.
The duct covers are not screwed to the duct trough, thus allowing rapid
inspection and refilling.
