Deep Dive into Rainscreens Session 8: Pressure Equalization and Compartmentalization

Building Enclosure Consulting Mixed Climate
Dr. John Straube | Ph.D., P.Eng. Principal. Senior Specialist

Deep Dive into Rainscreens Session 8 delves into two intriguing but often misunderstood design considerations: pressure equalization and compartmentalization of the air cavity.

RDH Principal and Senior Building Science Specialist, Dr. John Straube, explains why pressure equalization is a complementary addition to drained rain control strategies. John will describe the components of a pressure-equalized rainscreen, summarize the factors that affect the degree of pressure equalization performance, and explain the role of compartmentalization in improving water penetration control.

You will learn:
– Pressure moderation/equalization as an additive rain control strategy.
– Physical components of a pressure-equalized rainscreen.
– Design and exposure factors that affect pressure equalization performance.
– When and how compartmentalization may improve water control.
