Moisture Study

Moisture Performance Monitoring of High-R Wall Systems

Moisture Study

Moisture Study Home Innovation Research Labs is soliciting qualified builders of new homes (no remodels or additions) to participate in a field monitoring study designed to better understand moisture performance of high-R wall systems. As part this study, sensors will be installed in walls to measure moisture content of wood frame materials, relative humidity, and temperature. The results of the study will provide valuable real-life data on long-term performance of walls constructed using energy efficient practices. The focus of the study is on wall systems with R-value of 20 and higher in airtight, high performance homes located in climate zone 4 or higher.

There is no cost to participate, all instrumentation will be provided, and builder names will not be disclosed in the final report (all sites will be reported only by general geographical location). Participating builders can submit multiple homes for participation in the study. Instrumentation will take place in the spring and summer of 2016; monitoring will continue at least into the summer of 2017.
