Learning Objectives:

  1. Identify the role that building construction transitions play (roof to wall, wall to foundation, and wall to disparate materials) in achieving a well-designed building envelope, including conditions that contribute to failure.
  2. Recognize the points in the design process where construction transitions need to be addressed and specific areas that require detailed attention.
  3. Review the conditions that promote movement of bulk water, moisture or vapor drive and how those conditions impact construction transitions, specifically at roof-to-wall, wall-to-foundation, and wall-to-disparate-material locations.
  4. Describe the importance of maintaining the continuity of water-resistive barriers and air barriers across construction transitions, and assess integrated sheathing products and systems as a means to achieve that continuity.

In this course, we will focus on three transition areas in particular: wall to foundation, openings, and roof to wall. Further, recognizing the innovations and risk mitigation needed in building envelope design, we will also look at the latest advances in all-in-one, integrated gypsum sheathing that include WRB and AB systems during manufacturing as alternatives to field-applied water and air barrier systems. These integrated systems have been shown to reduce improper field installations, speed up installation, and save time and money during construction. As such, greater reliability and less risk have been found in using such integrated solutions compared to separate field-applied solutions.

Georgia-Pacific Gypsum The Georgia-Pacific DensElement® Barrier System, with AquaKOR Technology, integrates the gypsum core and the fiberglass mat to form a hydrophobic, monolithic surface that blocks bulk water, but allows vapor to pass through. The Georgia-Pacific DensElement® Barrier System eliminates the need for building wrap, fluid-applied membranes or peel-and-stick membranes. It’s faster to install and can be installed when it’s wet outside–saving time and labor. The all-in-one Georgia-Pacific DensElement® Barrier system is finished with DensDefy Liquid Flashing to fill and seal joints, fasteners, openings, penetrations and transitions. The Georgia-Pacific DensElement® Barrier System is ABAA listed and WRB-AB approved and has a customized MasterSpec® specification –061656 Air and Water Resistive Sheathing Board.
