NICHIHA INSTALLATION GUIDE FOR SIX-FOOT HORIZONTAL PANELS
28
LAST COURSE
ALL APPLICATIONS
Fasten Spacer (FS 1010) to studs at the top
of the last panel course. This is needed to
maintain the rainscreen without using the
clips. Cut panels (horizontally) to properly fit
at the roof line (or at the proper transition
point). Face-fasten panels at the studs and
through the green Spacer (FS 1010) all along
the top. Apply low adhesive tape to panel
face at face fastening locations and remove
only after applying patch and touch up paint.
Pre-drill panels 1” from the top (cut) edge.
Fill counter-sunk fastener holes with exterior
cementitious filler, such as MH Ready Patch®
and paint to match panel with a high grade
exterior latex paint.
Alternatively, utilize the Finish Clip instead
of face fastening. Cut panels horizontally to
properly align with the roof line or transition
point height. Use biscuit joiner to route
notches into this cut edge, spaced to coincide
with stud locations. Add 5mm corrugated
Spacer (FS 1005) at Finish Clip fastening/stud
locations prior to fastening clips. Set panels
into place and seat/fasten a clip at each stud
location.
Cover top panel row edge with roof cap/
coping, where applicable. (Figure 55)
GABLE & OVERHANG
Allow a minimum of 1” clearance (as per local
building codes) for AWP above a roof line.
At top, cut the panel to follow the slope of
the gable. (Figure 56)
When installing soffit, the wall panels should
be installed first, with the soffit installed over
the panels.
Panels installed along gable edges must be
face fastened. When adding face screws,
apply fasteners at least 1” from any panel
edge. This will avoid cracking or breaking of
the panel.
All face-fastened panels must be shimmed out
with FS 1010 Spacer.
Seal all cut panel edges with 100% acrylic
primer or paint. Do not leave any panel edges
exposed. Clean any cut panels to remove
dust.
Essential Overhang Flashing may be used at the
base of overhangs/bump-outs or porte-cocheres.
Prior to panel installation, fasten Overhang
Flashing at each stud location, beginning with
corner segments. Main segments will slide
under/overlap corner segments.
