Day 62 - (7/8/05) Here are my 6 cases of Green Glue. This stuff will be sandwiched between 2 layers of drywall on all of the theater walls and ceiling. It works to dampen sound and vibration and should give me an STC value in the mid 50's which should keep most sound in the theater as well as noise and footsteps out.
