NICHIHA INSTALLATION GUIDE FOR SIX-FOOT HORIZONTAL PANELS

SIX-FOOT HORIZONTAL PANEL
INSTALLATION
AWP installation proceeds by working
from left to right.
Wood, Metal, Concrete/Masonry
with Furring
For six-foot AWP, trim off the left side ship-
lapped edge so the panel will fit tightly
against an already installed inside corner
spacer, Sealant Backer, or outside corner trim.
If starting at an inside corner, predetermine
which wall will include the Single Flange
Sealant Backer for an inside corner detail.
Consider the location to minimize the visibility
of the sealant joint line. Clad the higher
visibility wall without the sealant joint first so
that the adjoining wall panels can terminate
to it with the Single Flange Sealant Backer
detail.
Set first panel into the Starter Track and
secure the top edge with a Panel Clip, placing
the first clip about one inch from the left edge
of the panel. Fasten clip at each stud location
the clip reaches. Every clip will cover 2-3
studs and must be fastened to each.
(Figure 31-32)
Proceed along the panel to the right, placing
another clip 3-4 inches from the end of the
previously installed clip so that the second
clip is roughly centered over the panel middle
but DO NOT skip any studs. Fasten clip at
each stud location.
Place the second panel next to the first,
making sure the shiplap joint fits tightly
together.
A rubber mallet or block of wood may be
used to seat the panels firmly in place and
tighten to the left. Do not hammer directly
anywhere on the panels as direct contact may
cause cracks, gouges, or chipping. (Figure 33)
Place a clip on top of this vertical joint.
Vertical joints should be spanned with a clip
covering the top edge of where the panels
meet. Fasten clip to each stud it reaches,
again not skipping any studs. Each long panel
edge should be supported by about 2.5 clips.
(Figure 34)
Verify the first course of panels is level. Large
commercial buildings require checking level
around the entire building.
Start the second row in the same fashion
as the first, but, in addition to the previous
steps, add the Vertical Joint Tab Attachment
against the bottom right hand corner each
panel. The Attachment seats inside the panel
clip, with tabs that fit on clip’s rainscreen
flange. Fasten the attachment to the panel
clip with the provided fastener. (Figure 35)
Fit panels tightly together on both horizontal
and vertical joints, ensuring the panel edges
are properly butted together.
Complete the second and remaining non-
terminal rows in the same way, with the Vertical
Joint Tab Attachments at the base of each
vertical joint. Terminal rows such as under
Compression Joints or at the Last Course are
covered in subsequent sections of this guide.
