Meeting at the Parapet: It was Transition at First Sight

This session will examine how transitions allow air and moisture to circulate in the building envelope, and potential problems caused by an improper seal in roof to wall, wall to foundation, and wall to disparate building materials. Learn what constitutes an effective air and moisture management system in the roof to wall transition. Examine vapor drive through foundation walls in transitions where underground moisture poses risks to above-ground interior spaces. Find out what issues may arise from transitioning between different materials – such as gypsum sheathing to concrete wall, and learn how material composition can influence compatibility, performance and maintaining the integrity of the design specification. Explore how the system’s water and air barriers create continuity at critical transition points, including the roof to wall at parapets where freeze-thaw cycles may occur in cold climates. A look at common design errors will help attendees identify and avoid them.

LEARNING OBJECTIVES:

  1. Identify and avoid potential problems in transitions including roof to wall, wall to foundation and wall to disparate building material.
  2. Recognize issues that may arise from transitions between different materials, such as gypsum sheathing to concrete wall.
  3. Grasp the critical role of a system’s water and air barrier at critical transition points like roof to wall at parapets, where freeze thaw may occur in cold climates.
  4. Assess common design errors and review strategies to avoid them.
