Critical Functions of Masonry Through-Wall Flashing Systems

Masonry through-wall flashing plays an important role in cavity wall construction by directing water to designated drainage paths. This course explains how flashing interfaces with masonry veneer, air and vapor control layers, insulation, and weep systems to promote effective drainage and protect wall components from moisture exposure. It reviews common flashing materials, accessory components, and required flashing locations, then connects these elements to detailing and specification decisions that affect wall performance over time.

Upon completion of this course, the Learner should be able to:

  • Explain the function of flashing in masonry cavity walls and its role in managing moisture intrusion.
  • Identify flashing materials and accessory components based on their suitability for resisting moisture-related deterioration.
  • Determine required flashing locations in masonry assemblies to reduce the risk of water accumulation and damage to structural components.
  • Recognize installation and specification principles that support effective moisture management and protect occupant health and safety.
