Helping Builders Meet Sound Control Code Requirements for Multifamily Walls

Homasote 440 SoundBarrier® offers an opportunity to reduce noise pollution and transmission for multifamily projects while requiring less labor and creating less waste.


For multifamily residents, noise is a critical issue. From music to voices, annoyances carrying through walls can quickly turn into major life disruptions that spill over to landlords and even back to the builder and designer. In fact, noise is the second biggest contributor to construction lawsuits, according to the American Institute of Architects (AIA), and is the biggest complaint of hotel guests, according to JD Power and Associates.

To help combat these issues, code requires multifamily buildings to meet minimum Sound Transmission Class (STC) ratings of 50. But going above that minimum threshold can make a significant difference in the comfort of residents and guests.

Using Homasote 440 SoundBarrier®, distributed by Weyerhaeuser, for multifamily walls offers an opportunity to meet these needs with less labor and less waste versus resilient channel or specialty sound-resistant drywall. Contractors can pull and install the same board for multiple applications and in the same space for maximum efficiency. For affordable applications, one layer of Homasote 440 SoundBarrier meets the requirements typically achieved with a double-stud wall, though a higher STC rating will be desired for higher-end applications.

Here’s a look at three methods for achieving STC ratings of 53 and 60 using Homasote 440 SoundBarrier with wood-frame construction:
