Joint design
There are different options for the
jointing of Gypsum Fibreboards. Some
specific rules must be followed for fire
rated linings. The following details show
the different joint options available for
fermacell Gypsum Fibreboards or
Dry butt joint – Gap ≤ 1mm

fermacell Firepanels A1.
It is important to choose the appropriate
joint design early on in the design
process. The following joint options are
suitable for fire rated linings.
Note:
Dry butt joints for fire
rated linings are possible
if there are no requirements for the surface
finish. Butt joints will be

visible in some finishes.
The installation needs to
follow the instruction as
per approval.
1)
The differential movement of the material must be considered if the Fermacell boards are fixed directly on to the CLT. Joints can open up due to the
differential movement of the substrate. This must be specially considered if
a wet screed system is being installed or heaters are used for the drying
out process.
