Shared walls, or party walls, between multifamily homes are an issue for builders and homeowners alike. They are more difficult to air seal effectively, leading to issues when trying to meet code.
Sealing party wall leaks is called compartmentalization. And research from the University of Toronto shows up to 20 percent of a neighbors’ air can transfer into a home through a shared wall. That’s why sounds and smells seem to infiltrate multifamily homes so easily.
Solution from AeroBarrier
The issue has been accepted as unavoidable, with no reliable solution, until AeroBarrier. By sealing the various gaps in shared walls, odors from air infiltration are stopped, and sounds are also mitigated. This issue isn’t always high on the builder’s or the homeowner’s list of concerns, if at all. But Josh Roy, Wasatch Group’s Vice President of Sustainability, has seen AeroBarrier’s sound mitigation improve the homebuying experience.
“Going into a fully-furnished unit with AeroBarrier, you notice the difference,” said Josh Roy, adding “It helps signal you’re in a well-built, quality home.”
