Webinar On-Demand: This On Demand CEU is a recorded presentation from a previously live webinar event. This course will summarize how to properly design critical building envelope control layers to protect against the air, water, vapor, and thermal loads to optimize energy efficiency. It also covers traditional multi-component backup wall assemblies and the challenges to achieve energy efficiency, installation, and long term performance. Learners will explore how to design with insulated panel wall systems achieve higher energy performance, faster build speed, and long term resilience. Finally the course covers how insulated metal panel wall systems provide extensive design flexibility while integrating with virtually any noncombustible rainscreen material.
