**************************************************************************

2.1.1
Vinyl Wallcovering [Type [A] [_____]]
**************************************************************************
NOTE: Select the appropriate vinyl Type designation
for each wallcovering specified and delete
inapplicable Types. Type selection should be based
on abuse conditions and the following
recommendations:
Type I (Light Duty) is satisfactory for use on
ceilings and light duty walls not subjected to
scuffing and abrasion. This type is rarely used.
Type II (Medium Duty) is satisfactory for areas
subject to average traffic wear and scuffing. It
may be used full height on walls or as a wainscot.
Type II should be used for most vinyl wallcovering
installations.
Type III (Heavy Duty) is slightly more resistant to
scuffing than Type II but is difficult to install
and clean, and is not available from most
manufacturers. Type III wallcovering is expensive
and should be used only where specifically requested.
Some manufacturer's Type I, Type II and/or Type III
wallcovering will overlap or vary slightly from the
weights shown in the following paragraphs.
