Building Science: Research Monitors Double-Stud Wall Moisture Conditions in the Northeast

January 26, 2015

Double stud walls reportedly have higher risks of interior-sourced wintertime condensation damage, and the Building Science Corporation went on to prove it.
“Field monitoring was installed in a Zone 5A climate house with 12” thick double stud walls,” Kohta Ueno of BSC wrote. “Assemblies included 12” open cell polyurethane spray foam, 12” netted and blown cellulose, and 5-½” open cell spray foam at the exterior of the stud bay.”
Data were collected for three winters. The first winter was mild (warm), and interior relative humidity levels were very low (unoccupied conditions).
