The engine enclosure shall be covered to reduce engine noise and reduce inside temperatures.
The under side of the engine enclosure shall be covered with a sandwiched material for interior cab noise and
heat rejection. This sandwiched acoustical material shall have one layer of 1/8" foam, a 3/16" single barrier
septum and a 7/8" layer of foam to provide on overall thickness of 1-3/16". The sandwich material shall be
chemically bonded to prevent layer separation. A finished surface treatment of metalized film shall be
provided on the engine side of the barrier. The acoustical barrier shall be held in place with mechanical

The front and rear floor areas of the cab shall be covered with sound barrier floormats. This floormat shall
be a three ply material with a 3/16" thick open cell isolation barrier of Polyurethane, a 3/32" thick closed cell
Nitrile mid barrier for section reinforcement, and a 1/16" thick embedded pebbled grain wear surface.
INTERIOR CAB STEP TRIM
The cab steps shall be completely enclosed behind each door. The toe kick surface shall be covered with
aluminum treadplate trim.
