Polyiso CI for Code-Compliant Walls in Types I-IV Construction
This course is no longer active. AEC Daily will not report completion information for this course.
There are a multitude of building envelope products used and a variety of methods taken for achieving energy and building code requirements. Understanding the different roles a product plays in the envelope simplifies its design. In this course we’ll take a look at: the code requirements for buildings classified as IBC Type I-IV, paths to achieving compliance, and the number of roles polyisocyanurate insulation plays in meeting these requirements.
Upon completion of this course, the Learner should be able to:
- Define continuous insulation (ci), the role of ci, and types and properties.
- Identify the applications of polyiso ci, including its use as exterior insulation, water-resistive barrier (WRB), and air barrier (AB), and as a multi-functional or composite performance sheathing.
- Recall energy code compliance, including prescriptive, U-value, and performance paths
- Recall building code compliance, including fire, wind pressure, and building science (WRB, AB, vapor retarder) considerations.
Approximately 1 hour, 30 minutes. Delivered online, at your own pace.
