NICHIHA INSTALLATION GUIDE FOR SIX-FOOT HORIZONTAL PANELS
10
PLANNING & PANEL LAYOUT
To ensure a successful installation, it is
important to first plan how the panels will be
laid out, where compression and control joints
will be located, and line of sight regarding
inside corners decided.
Reminder: Six-foot AWP actual dimensions
are metric: 455mm (h) x 1,818mm (l).
Layout: Six-foot AWP can be installed
in a stacked bond or a staggered bond
application.
Vertical Control/Expansion Joints: 10mm
(3/8”) sealant joints account for thermal
expansion in the lateral dimension. These are
often, where possible, aligned with window
or door jambs, downspouts, or other features
in order to minimize their appearance.
Depending on sheathing type, additional
framing, furring, or blocking may be required.
Horizontal/Compression Joints: ½” (min.)
horizontal, flashed break detail to allow for
building compression at floor lines.
Inside Corner Line of Sight: Sealant joints at
inside corners can be placed out of view from
the primary line of sight of a wall. Place the
sealant joint on the less-viewed corner wall.
CUT PANELS: In general, it is best to avoid
cutting AWP to short or narrow strips and
segments of less than 9”. Specifically, when
an individual panel is wider than a window
or other opening and is used over the head
or under the sill, do not cut it to less than
9” in height. (see image A)
When an opening is wider than an individual
panel and two or more are needed to cap
over the header or cup the sill, do not cut
the panel to less than 4” in height.
