Moisture intrusion in a wall system can cause building defects, as well as health ailments for building occupants, making rainscreens a very important tool in water mitigation. This course will review causes of moisture intrusion, specifically forces that drive rainwater into a building. We will identify rainscreen technologies, testing standards for rainscreens, the importance of considering wind loads and how commercial architectural wall panels can be used as a rainscreen.
- Describe the cause and effect of moisture intrusion in a wall system.
- Examine the importance of rainscreens and weather barriers in water mitigation.
- Identify examples of rainscreen technology and testing standards that measure rainscreen performance.
- Discuss how some commercial architectural wall panels act as a rainscreen and review how wind loads can affect their performance.
