Moisture intrusion in a wall system can cause numerous building defects as well as health ailments for building occupants. This course will review the cause and effects of moisture intrusion and will discuss how fiber cement panels can be used as a rainscreen to mitigate this moisture. We will identify different rainscreen technologies and ASTM and AAMA testing standards that measure their performance. By the end of the course you will understand basic design approaches and guidelines for installing fiber cement panels as a rainscreen.
