The owners of this Bangor nightclub had been the target of noise complaints for months. They were re-issued a special permit to stay in business, but only under the condition that they take steps to significantly increase the soundproofing.
A single wall was the weakest link. Three walls were concrete, but the fourth was a standard single stud wall. It was recommended to completely remove the old wood wall and replace it with a standard double stud wall using standard R13 fiberglass batts. On the inside they used three layers of standard 5/8” drywall and two tubes of Green Glue per 4’x8’sheet. On the outside they used three sheets of standard “T-111” exterior siding and and two tubes of Green Glue per 4’x8’sheet.
To attempt to correct this problem a new wall was built in front of the original. This proved to offer no improvement over the original wall. It was considered “a serious problem”.
To finally solve the sound problem once and for all, a layer of Green Glue was added to one side of the wall only, with an additional sheet of drywall.
Final Upgrade with 4 Layers of Green Glue
- Outside: Add two sheets of OSB with 2 tubes of Green Glue
Inside: Add two sheet of 5/8” drywall with 2 tubes of Green Glue.
- Sealed perimeter of walls and caulk around outlets.

“The sound problem has been completely eliminated.” “We hosted the City Council to demonstrate the effectiveness of the new wall.” A report of the meeting appeared in the Bangor Daily News.
“We really turned up the volume to give the council an idea of the sound levels inside during operation. Then everyone went out into the parking lot.” From the newspaper article: When councilors and residents stepped out into the parking lot for the sound demonstration, many commented on the positive effects of the wall.
“There is a ‘wow’ factor as everyone comes out,” council member Gerry Palmer noted.
“The sound from the mercury vapor lights was louder than what was coming out of the building when standing 15 feet away.”
“We hired local labor to construct the wall. The biggest pain was removing the old wall.”
