%PThis course provides an introduction to water management in commercial window systems. The course begins with a review of the basic principles involved in preventing water leakage in wall systems. The course then explores the ways that these basic principles can and should be applied to windows as well. Water leakage prevention strategies for three distinct window applications − punched openings, ribbon windows and window walls − are explained, including a detailed case study of large installation in a historic building. The course ends with a review of a series of strategies for ensuring that the performance specified for a commercial window system is actually achieved in the field.
