Designing Rough Openings
for Proper Drainage and Drying
CEU Credit:
1 AIA LU/HSW
Program Description:
Ensuring the proper installation of rough opening flashing systems is critical to building durability, moisture management, and energy efficiency. This presentation will examine common failures, correct installation techniques, and testing methods for rough opening flashing materials. Attendees will gain insights into proper sequencing, drainage and drying mechanisms, and the differences between vapor-tight and vapor-permeable systems. Additionally, the session will highlight current research on vapor-open rough opening solutions, helping designers and builders make informed decisions to improve air and water barrier performance while ensuring long-term building envelope resilience.
Learning Objectives:
Explain rough opening installation systems as described by published guidelines.
Understand rough opening testing and determine proper sequencing for rough opening installation.
Recognize drainage and drying mechanisms and the benefits of permeable rough opening systems.
Learn the differences between vapor tight and vapor permeable rough opening systems.
