Moisture intrusion in a wall system can be the cause of building defects, as well as health ailments for the building's occupants, making rainscreens a very important tool in water mitigation.
This course will review the cause and effects of moisture intrusion, and more specifically the forces that drive rainwater into a building. We will identify different rain screen technologies and ASTM testing standards that measure their performance. We will discuss fiber cement panels and how they can be used as a rain screen to reduce moisture build-up, rotting interior walls and mold growth.
By the end of the course you will understand basic design approaches and guidelines for installing fiber cement panels as a rainscreen.
