Discuss some foundational principles and knowledge related to building science regarding practical applications and considerations 2. Identify the key aspects to controlling water vapor using continuous insulation to avoid condensation and moisture accumulation 3. Explain the different ways of managing rain water with various waterresistive barrier (WRB) methods, including use of foam sheathing with tape joints and adhered flashing, use of a separate WRB, etc. 4. Explain various tried-and-true techniques and detailing sequences to install and flash windows together with foam sheathing and the various WRB strategies that may be considered good, better, and best practices 4 Lstiburek buildingscience.com 2 of 51

3 Learning Objectives One of the most controversial yet important subjects affecting modern housing construction is insulation and moisture control. This webinar will address relevant building science principles, materials & methods of construction, practical insights and useful resources related to the appropriate integration of foam sheathing (continuous insulation) onto wall assemblies for code compliance and durable performance. 5 What is a Building? 6 Lstiburek buildingscience.com 3 of 51
