Wind Load and Air Barrier Performance Levels
Construction Specifier, July 2014, by Maria Spinu, Benjamin Meyer and Andrew Miles.
"Continuous air barriers have become mandatory for the building envelope, with energy codes recognizing the importance of air leakage control. However, simple inclusion of an air barrier requirement does not guarantee the desired performance in the field. These systems must be properly installed, meet the building envelope structural wind loads, and maintain their function over time.
