Dynill barrier vs 2 layers of sheetrock, hat channel, and green glue
I'm working with a home theater contractor and discussing the construction of my dedicated room. In the past, I have used the hat channel, sheet rock, and green glue, and have been very pleased with the results. However, this contractor is advocating for the use of dynill, and says that for a very similar cost, could achieve superior sound isolation. I've only really seen the green glue and hat channel discussed primarily here, so I was curious of the opinions on dynill and if that would truly give me better results.
