Building science is a complex topic. Managing the transmission of heat, air, and moisture means considering many factors within a single assembly. Some of these factors are out of the building designer's hands, such as climate zone, building occupancy, and local code jurisdiction. Others need to be determined based on sound science, practicality, and value. A building envelope that includes foam sheathing continuous insulation can check off serveral boxes simultaneously, potentially reducing the amount of labor required in construction. Always verify material properties and code compliance with the manufacturer.
