Shortly after buying our '87 Westy on '06 I pulled everything behind the front seats to inspect for rust. �Found none and decided while there to soundproof. �I purchased B-Quiet from a company in Lethbridge AB Canada, eventually three of the 50' x 12" rolls of their product, a foil-backed asphalt type stuff about 3mm thick.

After running out of that I did the front doors and used stuff you'll no doubt be warned against, a peel & stick roofing material from the local home improvement store that looks identical and costs about half per square foot what the BQ did. �Despite dire warnings about offgassing and the like I could detect no difference in performance and effect between the two products and you can have a vanload of the P&S stuff in an hour rather than awaiting shipment from the Far North. �

I'll dig up a link to pix and post that also. �I also used normal wall insulation that seems to help quell the noise, but it's actually hard to tell when underway in a Westy since I'm sure the open hole for the poptop, the roof itself and the luggage rack all contribute to the noise level. �All that work might have greater benefit in a hardtop, but you sure can tell the difference when shutting the front doors, slider or hatch. �They now give a solid thump on closing rather than the customary clang. �

There are numerous Samba threads on this topic and I think someone even instrumented the noise levels before and after, but I forget the result. �Whatever, it's a bonding experience to crawl around in your van trying to improve it and it's like chicken soup; doesn't hurt and it might help. �Good luck!
