This is a classic seminal paper on rain penetration control in general but really focuses on “open rainscreen” approaches. Although it is now almost 60 years old, its compact presentation and clarity is still hard to beat. However, there are a few details that need comment to reflect some things we have learned and changes in how we build. Hence, I have added comments in italics throughout.
