The objective of this report is to communicate, in a very concise form, some of the accomplishments of the MEWS (Moisture Management for Exterior Wall Systems) project. This will be done in terms of the research methodology adopted, as well as the outcome of its application to the first type of walls analysed in the project - Stucco-clad exterior wood-frame wall assemblies. Only a few examples will be cited in this report. Many reports have been produced detailing the process followed and the results obtained. The interested reader is welcome to refer to these documents for a more detailed investigation of any selected topics.
