IECC Compliance Options for Wood-Frame Wall Assemblies
Technical Guides
Energy efficiency in residential construction is a high priority for builders working to meet more stringent energy codes and for homeowners who are gaining a better understanding of the value of energy efficient construction.
This publication is designed for: builders, homeowners, designers, engineers, architects
This joint APA and International Code Council (ICC) publication describes how energy performance is measured in exterior wood wall assemblies and how builders can improve wall thermal performance to meet code requirements. By following the design recommendations in this publication, builders can achieve the R20 or R13+5 wall insulation values found in the prescriptive residential tables of the 2009, 2012, 2015 and 2018 versions of the International Energy Conservation Code (IECC).
Key sections include:
Energy efficiency of wood frame walls
Design considerations for energy efficient wall assemblies
Framing factors
Advanced framing
Header R-values
IECC-compliant wood frame walls
Four versions of an R20 assembly
One version of a better than R20 wall assembly
