Conventional building practice consists of single functional materials combined to serve the building design needs. For example, an air barrier is a distinct and separate layer, and water resistive barrier is often a separate layer. New designs concepts where multiple functionality, such as air and water barriers, can be met at the same layer per building code will be discussed. In particular, if insulated foam sheathing is used, appropriate joint treatment can enable compliance as air, water, and thermal barriers. Both conventional solid (peel and stick), and new fluid applied flashing and barriers will be discussed. Participants will also gain an understanding of material options and impact of application techniques on long term building performance.
