Deep Dive into Rainscreens Session 4: The Value of Ventilation

Deep Dive into Rainscreens Session 4 delves into the second most important performance aspect of a rainscreen wall system: ventilation.

RDH Principal and Senior Building Science Specialist, Dr. John Straube, will explore the benefits of ventilation for common types of cladding and review practical applications for achieving vented/ventilated rainscreen wall designs. John will explain ventilation concepts ranging from the fundamental need for ventilation to more advanced concepts like pressure equalization and compartmentalization.

You will learn:

– The difference between vented and ventilated air gaps.
– The design impacts of including or not including an air gap within a wall design.
– Building materials and methods that create effective air gaps.
– How the concepts of pressure moderation/equalization and compartmentalization apply to the design of air gaps.
