Method Two (alternative):
Install Nichiha Corners in sequence with
panels. Plan to work an entire corner section
at one time, using Vertical Control/Expansion
Joints, breaks, or other termination points as
starting and stopping locations.
During horizontal panel installation, when
reaching an outside corner, do not add the
last panel.
First, set a Nichiha Corner piece on the
Starter.
Measure and cut the last panel ¼” short of
the edge of the Nichiha Corner piece and
install it on the Starter.
Place the final Panel Clip so that it extends
toward the outside corner edge, spanning
over the ¼” gap and sitting on the top
shiplap of the Nichiha Corner.
On the other side of the corner, remove ship-
lapped edge of the first panel, seal the cut
edge, and install the panel ¼” away from the
edge of the Nichiha Corner.
Set a Panel Clip so that it covers the top edge
of the Nichiha Corner, spans the ¼” joint and
over to the top of the first panel.
Repeat as work progresses left to right and up
the wall.
After all panels have been installed, add ½”
closed-cell foam backer rod to the ¼” vertical
joints and apply sealant at 75% - 80% depth.
Sealant must be compliant with ASTM C-920.
