Wall Liners
**************************************************************************
NOTE: Wall liners will be specified when necessary
to provide protection to the insulation and will be
the minimum height consistent with the use of the
building. When full-height liners are required,
they should be specified under this paragraph in
lieu of using factory insulated panels. Wall liners
of plywood, hardboard or other suitable materials
may be used when considered to be more appropriate
than sheet metal liners and when these materials
will meet the fire hazard classifications required
for the installation. If alternative liners are
used, omit the following paragraph and show the
