NICHIHA INSTALLATION GUIDE FOR SIX-FOOT HORIZONTAL PANELS
6
CONTINUOUS INSULATION
Where exterior/continuous insulation is used,
AWP may be installed directly over up to
1” of foam plastic insulation, depending on
sheathing type. Amounts greater than one
inch require a structural solution to provide
attachment points for the AWP system such
as a furring grid or third-party specialized
system. Please contact Nichiha technical
department for further assistance.
WEATHER RESISTIVE BARRIERS
A weather resistive barrier (WRB) is required
when installing Nichiha panels. Use an
approved WRB as defined by the 2015 IRC.
Refer to local building codes.
A breathable WRB is highly recommended
when installing Nichiha panels for residential
applications.
Breathable WRB is required for all commercial
applications. However, fluid applied WRB is
acceptable.
All openings must have appropriate flashing
to prevent moisture penetration.
Follow manufacturer’s guidelines and all local
building codes.
PRODUCT INSPECTION
Inspect all products thoroughly prior to
installation. Do not install any product which
may have been damaged in shipment or
appears to have a damaged or irregular
finish. Should you have a question or problem
with your order, contact your local dealer
or Nichiha Customer Service, toll-free, at
1.866.424.4421.
STORAGE AND HANDLING
Panels must be stored flat and kept dry before
installation. Refer to storage information
included on product pallets.
If panels are exposed to water or water vapor
prior to installation, allow to completely dry
before installing.
Panels MUST be carried on edge. Do not
carry or lift panels flat. Improper handling may
cause cracking or panel damage.
Direct contact between the panels and
the ground must be avoided at all times.
It is necessary to keep panels clean during
installation process.
The custom color finish of Illumination Series
panels requires 30 days to fully cure and
extra care must be taken to avoid damage
to the paint during the installation process.
Cut the panels with the face down. Always
clean panels with a clean, soft, dry cloth after
cutting as dust may bind to finish.
