This module provides a focused introduction to EPS insulation as it relates to roofing applications. Learners will begin by exploring why insulation is used in roof assemblies and how R-value influences thermal performance and long-term building efficiency. The course then compares common insulation types used in roofing to help clarify where EPS fits within the broader insulation landscape.

A core part of the module focuses on EPS itself, outlining its key properties and advantages and how these translate into reliable performance in roofing systems. Learners will be introduced to both board insulation and tapered insulation, with an emphasis on how each is used to support thermal control and roof drainage.

The module concludes with a practical overview of EPS roofing applications, including flat and low-slope roofs, tapered drainage systems, and metal deck assemblies. By the end of the course, learners will have a clear understanding of where and how EPS insulation is used in roofing and the factors that influence effective system design.
