There are several key elements that must be considered with a cavity wall system. Heat, air, and moisture — both vapor and liquid — have a definite impact on how a cavity wall system should be designed and constructed. Once these elements have been addressed, a cavity wall system will increase energy efficiency, meet the required energy and fire code standards, and will provide cost-savings over the life of the building.

Upon completion of this course, the Learner should be able to:

• Identify the key concepts for proper design of cavity wall construction to manage the movement of heat, air, and moisture (vapor and liquid).
• Introduce the importance of the hygrothermal (dew point) analysis.
• Articulate current energy and fire codes that must be complied with in the construction of exterior walls.
• Explain the role that continuous insulation can play in meeting design and code requirements for cavity wall applications.
• Describe the critical design element needs to ensure continuous air and vapor barriers in roof-to-wall transitions.
