I just wanted to let everyone know that I finished a home theatre recently and I disregarded all the so-called evidence and "independant" lab results citing that Green Glue is the best thing since man discovered fire. Yes, that's right. Even after the controversial post a little while back, as well as my own so-what results using Green Glue in the past... and after reading, well trudging through really 45 pages of song and praise for the almighty Green Glue... I did the unthinkable. I used a drywall sandwich technique using... gasp. SILICONE!
Ok, I gotta be honest. I started out with 100% silicone, which is a huge saving over green glue. Still, silicone is the most expensive caulk at the *gasp again* big box Home Depot / Lowes store. I later switched to some silicone/latex type of caulk that was really, really cheap. I did all of this and disregarded all the internet experts saying how great and mighty green glue is, and how bad silicone is. Haha! Silicone not viscoelastic?! Whatever, rocket scientists.
I'm sticking to my belief. You stick to yours. I'm rubber, your "green glue", whatever you say bounces off of me and sticks to you! OK, that was just a joke. Anyway, good luck to all you super rich contractors out there who like to use "real" soundproofing products. For the cheapskate in me, I wish you well.
