Re: Rock wool vs. Acoustic cotton vs. OC703


It's kind of a hobby for Bob. It's a nice reference when you want to compare things. Don't get too hung up on tiny differences as some were done in different labs and certainly on different days. They're also only as good as the manufacturers' specs.

In general, the JM814 is pretty much a direct replacement for OC703 inch for inch. When you're looking to buy, remember that while local is generally cheaper, sometimes the local guy wants a ton more - and local you have to pay sales tax. Just make sure to do all the homework to really compare total costs.
