Continuous Insulation in Framed Exterior Walls
Learning Objectives:
- Explain the concept of thermal bridging and how it impacts building energy usage.
- Define the commercial and residential wood-framed wall insulation requirements found in the 2015 International Energy Conservation Code (IECC).
- Discuss how condensation forms in wall cavities, and investigate strategies to mitigate risk of damage to construction, while promoting healthful indoor environments.
- Compare green or sustainable building characteristics of various continuous insulation alternatives, as part of the exterior wall assembly.

Building codes and green building standards are continuing to raise the bar on energy efficiency and high performance in buildings. In wood-framed buildings designing for thermal and moisture management in wall cavities, as well as the air tightness of the building enclosure, are all core components to creating advanced building enclosures. This course will discuss the need for exterior insulation to manage heat transfer and reduce condensation in exterior walls by providing step-by-step examples of how to determine the amount of continuous insulation required to meet prescriptive code requirements depending on climate zone.
