General Notes: 1. R-values for existing materials and total assemblies were calculated based on methods described in ASHRAE Fundamentals 2013. The State of Maine has not yet adopted Ashrae 90.1-2013 but those standards are included in this summary. 2. For roof insulation R-38 is required in pitched roofs because the batts are not continuous. On Low Slope roofs over metal decks, the code requires R-20 ci which means continuous rigid insulation.
