danger



Do not install any flammable material directly

above or around the compartment. Heat,

transferred through the compartment structure,

may be sufficient to ignite, char or discolor

seat cushions, fiberboard and other flammable

materials. Use approved nonflammable insulat-

ing materials in high temperature areas.

2.2.3 sound InsulatIng MaterIals

Once installers have determined that a compartment

is properly constructed and metal lined, they can add

acoustical material. This may include additional seal-

ant or insulating material, to reflect noise away from

the vehicle interior.
Sound insulating materials should be of a nonflam-

mable type. One excellent insulating material is a 1-

inch (25 mm) thick fiberglass having a 2-pound den-

sity. When fiberglass is used, its coated side should

face toward the compartment interior.

danger



Do not install sound insulation or any absorbent

material on the compartment floor interior. Such

materials will become soaked with combustible

or explosive vapors and liquids and will become

a fire hazard.

Using a combination of sound insulating materials

can often reduce noise more effectively than a single

material. For example, a sheet of lead or visco-elastic

material, along with a layer of other acoustical mate-

rial, is more effective than when a single material is

used.

2.2.4 acoustIcs

For additional noise abatement, the installer may

wish to consider the following:
• Using special sound insulating materials.
• Construction of a special noise abatement

compartment.

NOTE:

Any method used to reduce noise must not

adversely affect the flow of cooling and ventilating

air into or out of the compartment.
In addition to the effective use of sound insulating

materials, construction of a special noise abatement

compartment might be considered to reduce noise

levels. Such a compartment might be constructed as

follows (Figure 2.6):
• Use 5/8-inch thick or 3/4-inch thick plywood in the

compartment.

• Construct the compartment floor of a double thick-

ness of 5/8-inch or 3/4-inch plywood.

• Line the compartment interior walls and floor, as

well as the underside of the floor, with 26-gauge

galvanized steel.

• Vapor seal all compartment seams and joints.
• Over the galvanized steel lining, install a combi-

nation of acoustical materials as mentioned in

Section 2.2.3.

danger



To prevent fire or explosion, do not install any

insulation or other absorbent materials on the

interior or underside of the compartment floor.

• Seal all compartment door edges to prevent noise

leakage around the door perimeter.

• Line the compartment door interior (except for air

openings) with suitable, fireproof sound insulation

(such as 1-inch (25 mm) thick fiberglass with a 2-

pound density).
