Panel Truck Insulation

[CMCamp]

I am looking to insulate the walls of my '62 K1001 Panel truck. I'm curious if anyone has come up with a way to get insulation into the lower half of the rear walls. In the panel truck these walls have a inner and outer wall with a void in between. What immediately comes to mind is to fill it with expanding foam, but putting that stuff into a constrained space could be risky. The foam can exert a pretty powerful force and bulging out the wall is possible. Does anyone have experience insulating a panel truck?

I'm guessing I might be the only on on our forum with exactly that kind of experience. I helped my Dad insulate the cavities of his new one ton panel which we converted into a Suburban in 1965. We used loose fill styrofoam beads poured in through the taillight openings. Dad made a pusher with a disc screwed onto the end of a long dowel to push the beads to the front of the cavities. A little messy, but it worked. I think you'd be asking for trouble using expanding foam.

Ed,

That sounds like a perfect solution! When I posted my question I was hoping at least one person had been through this. Thanks for your response.

Let us know how it works out for you.

By the way, Dad was from East Syracuse, not too far from you.

The beads are on order! I’ll let you know how it goes.
