Floor/side wall foam

[Pat Stewart]

In several pictures I have noticed foam placed between the ribs in the floor prior to installing the top floor skin. I am assuming this is for noice reduction and would like to do the same. What foam is available and where can I get it.

We use super soundproofing which is water proof. We get the self stick type.
We purchase it at a/c spruce. The company that manufactures it sells it in 25 ft sections as well (which may be cheaper). For the rv10 we used 21ft of 1/4 inch on the floor , baggage bulkhead and sidewalls. We used 1/2 inch for the firewall. The manufacturer's website is www.soundproofing.org. Click on planes and you can find more info.
