LIGNMENT
Before panel installation begins, the wall structural support framing must be checked for straightness
and alignment, and must be checked to verify that the wall panels can be installed without interference.
Intermediate framing member’s alignment tolerances are as specified below:
zero to
1
“ outward of the structural support line for members spaced at 10’-0” or greater
zero to
1
“ outward of the structural support line for members spaced between 5’-0” and 10’ -0”
zero to
1
1
“ outward of the structural support line for members spaced at less than 5’-0”
Wall framing alignment error and interference must be corrected prior to the start of panel installation.
The manufacturer is not responsible for difficult panel joint assembly and panel face rippling or
buckling resulting from misaligned wall framing.

Panel side joints are a modified tongue and groove assembly. Every panel joint must be fully engaged.
Due to normal fabrication and field tolerances, the actual panel coverage may vary between plus
1
”to
minus
1
1
” when panel joints are fully engaged. The joint gap is the visible vertical space between the
edges of the exterior faces on the adjacent panels. When panels are fully engaged, the width of the joint
gap is typically plus
1
1
” to plus
1
”.

If installed correctly, the combination of sealants and insulated panels forms the buildings vapor
barrier. Because of increased thermal efficiency of insulated panel walls over other typical cladding
products, there is a potentially greater vapor pressure differential between the exterior and the interior
side of the wall. This higher vapor drive requires tremendous attention to detail regarding the
application of sealants. Because of the critical requirements of the weather and vapor seals, the installer
should understand the principles of vapor drive and water migration and must understand the
requirements for the effective moisture and vapor control.
