ARRANGEMENT
The Scyon™ Matrix™ cladding panels must be fixed to the Scyon™ cavity trim. The Scyon™ Matrix™
cladding panels can be installed in a horizontal or vertical orientation. The panels are installed with a 10mm
expressed joint between adjacent panels, vertically and horizontally
VERTICAL JOINT
Join ScyonTM Matrix™ panels to James Hardie technical specification. (Refer to Figure 16, 17 and 18 of
the Scyon™ Matrix™ Installation instructions)
HORIZONTAL JOINT
At horizontal panel joints, the JH backing strip is bonded to the back of the Matrix panels to form a socket
to which the next course of panels are fixed over. The lower side of the JH backing strip can be bonded
using either James Hardie joint sealant or double sided backing tape, such as Henkel C3 12mm wide
double sided tape. (Refer to Figure 16, 17 and 18 of the Scyon™ Matrix™ Installation instructions for
details of construction of a horizontal joint)
