Christine Williamson: Confusion about Rainscreens | BSFC | AIA

Christine Williamson is the Director of Building Science & Education at Acelab and the founder of Building Science Fight Club (BSFC). Check out the full course at: acelabusa.com/...
In this video course, she explains how there isn’t really a consensus on what “rainscreen” means. Some professionals describe specific products as rainscreens and others use the term more generically to refer to a wall design that incorporates drainage behind the cladding, and still others suggest that the term has something or other to do with ventilation and pressure. It’s confusing! This short presentation sorts out the physics and the terminology so that professionals can have a better handle on what that space behind our cladding system is really doing and how large it ought to be.
