Bob -
I recently purchased MLV to lay under the subfloor. (To refresh - I have to tear up my hardwood floor due to water damage, so I am repairing the subfloor, laying down the MLV, and putting the wood on top). We are starting in a few weeks. I read about the guy who is doing something similar. You mentioned to him that he could use a 'closed cell foam' product to reduce noise further. What is this, where do I get it, and can I simply place it between my subfloor and the downstair neighbors ceiling?
Thanks,
Josh
