Moisture Performance Comparison of Typical Residential Wall Assemblies

An independent 3rd party building products laboratory, a wholly owned subsidiary of the country's pre-eminent trade association for the housing industry has recently completed a year-long field moisture study entitled "Moisture Performance Comparison of Typical Residential Wall Assemblies." The project's objective was to determine how exterior cladding can impact the moisture content of the wooden components in the wall construction, and the research was funded by the Brick Industry Association, the U.S. Department of Agriculture's Forest Products Laboratory, and the U.S. Department of Housing and Urban Development. The results are in. Of the eight wall systems tested, which account for roughly 90% of the cladding systems used today, brick veneer wall assemblies performed the best overall in controlling moisture.
