Taking Sound Attenuation to another LEVEL

I share some tips on sound attenuation—how to lessen or diminish the sounds that inherently travel through the walls in multifamily housing. Because quiet neighbors make the best neighbors!


NS Builders is known for going the extra mile—really listening to our clients and finding out what is important to them. At our Cambridge project, the homeowner expressed concerns about wanting a “quiet” apartment and what steps could be taken to reduce the sound filtering in from the neighboring units through shared walls. So, we got to work on finding practical solutions to make this request a reality.

We’ve upgraded from fiberglass insulation to mineral wool insulation. Mineral wool batts are designed to provide acoustical control and fire protection. It’s easy to install and makes a world of difference. In fact, it’s so quiet in this space today that it’s almost eerie—but in a good way!


In conjunction with the mineral wall, we’re using putty pads. Putty pads are made from intumescent putty and are sized to fit around a standard electrical box. They are used as a fire-stopping product and also to block sound transmission. Sound waves that enter a wall can make their way through the metal or plastic electrical boxes. For example, we’re looking at the backside of the neighbor’s wallboard and one of their receptacles. Sound from their unit is going to flow right on into this unit. Putty pads are simple to install, and we secured permission from the neighbor to wrap these boxes. It’s a win-win for everyone in creating a much quieter environment.

It’s time to discover what NS Builders can intentionally craft for you! Contact us today to get started on your custom dream home. Together, we can make it happen.
