Precast concrete enclosure walls stand apart from most “rainscreen” walls in several key respects: how they control rain penetration, how they provide airtightness, and their sequence of construction. This guide reviews the requirements for high performance enclosures as they apply to precast concrete, with special emphasis on the control of rainwater penetration.
