Boardwalk Condos Case Study

The original 1892 building was a furniture manufacturing plant located in downtown Grand Rapids, MI. Then in 2000 the
The original wall between units was considered very inadequate for sound isolation. Casual voices were easily audible as well as television and light music.building received a complete urban makeover converting the building into apartments. During 2002 an attempt was made to correct the poor sound isolation performance of the original wall. In 2007 the building received extensive remodeling including adequate soundproofing on the common walls between condominium units.

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.

“The results are amazing. Since installing the Green Glue, we have not received a single noise complaint. We are very pleased with the results.” “We placed a very loud air compressor in a bedroom as a test. This was much louder than a typical condo owner would play music. In the room next door we heard nothing. It was unreal.” “Our installers found the Green Glue tubes to be extremely fast and easy to work with.” “We tried other methods of soundproofing such as soundboard or resilient channel, and found Green Glue to be the least expensive and clearly the best performance.”
