NICHIHA INSTALLATION GUIDE FOR SIX-FOOT HORIZONTAL PANELS
26
HORIZONTAL/COMPRESSION JOINTS
ALL APPLICATIONS
For any buildings of three or more stories
or 45 feet, horizontal compression joints
are required.
For metal framing, add a joint every 25 feet
for projects of more than three stories. For
wood framing, a joint is required at each oor
for projects of three stories or more. Avoid
spanning oor lines with panels at joints.
Please contact the Nichiha Technical
Department for assistance.
INSTALLING A HORIZONTAL
COMPRESSION JOINT
Install Essential Compression Joint Flashing
or a heavier gauge z-shaped metal flashing
or drip cap over the top edge of the course
of panels terminating under the horizontal
compression joint location. Fasten Flashing at
each stud location. A best practice is to add
flashing tape to cover the top edge of the
flashing and its fasteners.
The top ship-lapped edge of the bottom
panel is cut and secured by face fastening (1”
below panel cut edge) or use of the Finish Clip
(JE310) with the appropriate Spacer behind:
10mm for face fastening, 5mm for Finish Clip.
Install Starter Track above trim or z-flashing
such that the next course of panels sit at
least 1/2 inch above the course below it.
Remember the bottom ship-lapped edge
of panels extend 3/4” below Starter, so the
Starter will need to be installed at least 1-1/4”
above the edge of the panel course below the
joint.
Check for level.

Continue to install panels according to these
guidelines with compression joints at the
appropriate elevation(s).
