Conference on Moisture Problems in Residential Construction: Separating Myth From Reality, October 17-18, 1985, Seattle, Washington. Sponsored by Washington Energy Extension Service, Oregon State University Extension Energy Program and Puget Power

Test structures were constructed near Madison, Wis, USA and Gulfport, Miss, USA for exposure of eight types of insulated wall panels at controlled indoor conditions and typical outdoor weather conditions. Panels were instrumented with moisture sensors and tested without and with penetrations (electrical outlets) in the indoor surface. Continuous internal vapour barriers effectively prevented cold weather condensation in all panels. Installation of an electrical outlet changed moisture patterns in both the cold winter climate and the hot, humid summer climate. Although condensation occurred for limitedtime periods in some panels at both test sites, the moisture content of framing did not rise to critical levels.
