  • All vapor retarders (VRs) are air barriers (ABs), but not all ABs are VRs. Wait, what? How can that be? This presentation provides the practical side to the AB/VR discussion and identifies common VRs and ABs, how they're installed, and why AB/VR approaches vary according to the type of construction and building use.

    Prerequisites: No

    Course Level: Introductory

  • Single-ply membranes, along with their installation methodologies, have evolved to best meet the roofing needs of today’s low-sloped commercial buildings. This course reviews the most prevalent membranes and describes the advantages and disadvantages of EPDM, PVC, and TPO. An overview of attachment methods is presented as well as a discussion of single-ply system strength, cool roof benefits, and condensation issues from a building science perspective.

  • An improperly ventilated house is susceptible to a range of problems, from mold growth and structural damage to increased energy costs. Achieving proper ventilation means understanding the flow of air into and out of the building envelope. This course discusses principles of proper ventilation in houses with steep-slope roofing—from the science behind moisture and airflow to the products used to assist ventilation through a structure.

  • Finding ways to improve the energy efficiency of buildings is a key focus of many codes organizations, designers, architects, and government groups. This course examines how the roof of a building—one of the few parts of a building envelope that undergoes periodic replacement—impacts energy efficiency. It also explores how roof design can be a key contributor to meeting both sustainability and energy operating cost goals.

  • Their cost, flexibility, and relative ease of installation are just a few of the reasons why single-ply roofing membranes have seen a growth in popularity over the years. With a focus on commercial roofing systems, this course explores the drawbacks of traditional asphaltic roofing, as well as the advantages and disadvantages of single-ply roofing systems and their attachment technologies.
