Pressure Equalized Rainscreens (PERs) for High-Wind Conditions (Replaced)

The typical challenges faced by designers of multistory building envelopes pale in comparison to wind forces of tornadoes and hurricanes. This course investigates how pressure equalized rainscreens (PERs) address heat loss, air infiltration, moisture migration, fire safety, and lateral forces—even under extreme wind and projectile testing. Aluminum composite material/metal composite material PERs are outlined in detail vis a vis standard tests, types of fabrication, and relevant building code requirements.

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

• Differentiate rainscreens from pressure equalized rainscreens and name the components of aluminum composite material (ACM)/metal composite material (MCM) pressure equalized rainscreens (PERs).
• Describe how rainscreens contribute to energy efficiency in the building envelope.
• Identify the standard test methods for rainscreen assemblies and wind design, including the requirements for high-velocity hurricane zones.
• Discuss how ACM/MCM PERs help reduce heat loss and air/moisture infiltration, and add high-wind and fire resistance.
• Interpret the code requirements for energy efficiency in building envelope design and performance.
