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.
