Lighter weight compromise

In my small remote truck ( we used the following technique:

o Foam between the aluminum ribs (blown in in the ceiling and cut blocks on the sides.

o Butyl weatherstripping between the ribs and the plywood sides. I think we used 3/8" plywood.

This gets good isolation at high frequencies, but does very little to block low frequencies. Like I said, it's a compromise... The entire truck is under 10,000 lbs...
