Figure 2.5 – Typical Compartment Construction

NOTE:

Caulking must be done so that the caulking material will stay in

place permanently. Pressing such materials as putty tape onto

joints and seams is not acceptable. A high quality silicone rub-

ber base sealant is recommended.

Holes and openings made in the compartment walls to allow for

•

the passage of electrical conduit, conductors, hoses, cables,

etc., into the vehicle living area must be sealed vapor tight with

silicone rubber base sealant.

If flexible metal conduit is used, it must be sealed internally at

•

the end where it terminates inside the compartment’s electrical

junction box.

NOTE:

Flexible metal conduit, due to its unique construction, is NOT

vapor tight along its entire length.

Seams and joints of the galvanized steel (whether used as a liner

•

or for the compartment itself) must be lapped and mechanically

secured. Such seams may be manufactured, welded, bolted,

riveted or screwed. Manufactured lock seams are shown in

Figure 2.6. Installer constructed compartments typically utilize

a standard lap joint.

After the compartment has been metal lined and vapor

•

sealed, line the compartment interior walls and ceiling with an

approved, nonflammable sound insulating material. See "Sound

Insulating Materials".



Do not install any flammable material directly

above or around the compartment. Heat,

transferred through the compartment struc-

ture, may be sufficient to ignite, char or dis-

color seat cushions, fiberboard and other

flammable materials. Use approved nonflam-

mable insulating materials in high tempera-

ture 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 sealant or insulating material, to reflect

noise away from the vehicle interior.
Sound insulating materials should be of a nonflammable type. One

excellent insulating material is a 1-inch (25 mm) thick fiberglass

having a 2-pound density. When fiberglass is used, its coated side

should face toward the compartment interior.



Do not install sound insulation or any absor-

bent material on the compartment floor inte-

rior. 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 material, is more effective than when a single material

is used.
