New energy codes dictate minimum thermal insulation requirements for roof assemblies, and recent changes to these codes may result in the need for significantly more insulation than you may be accustomed to providing. This new publication provides a step-by-step guide for complying with the requirements of the International Energy Conservation Code's (IECC's) 2009 and 2012 editions and ASHRAE 90.1, "Energy Standard for Buildings Except Low-Rise Residential Buildings," 2007 and 2010 editions, which are referenced in IECC's 2009 and 2012 editions, respectively.
