◆2.2.3 SOUND INSULATING MATERIALS

Once installers have determined that compartments are 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 non-flam- mable type. One excellent insulating material is a 1 inch thick fiberglass having a 2-pound density. When fiberglass is used, its coated side should face toward the compartment interior.

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 COMPARTMENT FLOOR CUTOUTS

Provide openings in the generator compartment for the following items (Figure 2.7):

•Engine exhaust and cooling air outlets

•Generator cooling air inlet

•Four holes for passage of generator mounting bolts. See “Generator Restraint” on Page 19.
