Free Webinar: How to Design and Build High-Performance Attics, November 29
Event Description

California’s new Title 24 energy code and Passive House recommends high performance attics. Summer attic temperatures can easily add ½ to 1 ton of air conditioning load. The 2016 and 2019 T-24 energy codes require these loads be mitigated. These codes prescriptively require attics and roofs with multiple layers of insulation in what seem to be in confusing and contradictory locations.

This class examines how to design and build high performance attics and roofs assemblies that delivery energy efficiency and occupant comfort while reducing the risk for water and moisture related failures.

The objective of this course is that at the conclusion, participants will be able to:

  • Explain the California Title 24 approaches to high-performance attics
  • Incorporate methods for designing and building energy efficient, high performance roofs and attic assemblies to reduce the risks of premature roof failures
  • Select the best insulation system for a given application
  • Compare the vented and unvented, sealed attic best practices
