Metal Building Insulation Energy Code Compliance Guide ...

1 Technical BulletinMetal Building Insulation Energy code Compliance GuideDepending on what Building code has been adopted and is enforced in the jurisdiction where the site is located, Metal buildings usually have to meet the Insulation requirements of either:1. ASHRAE Standard , or2. The ICC international Energy conservation code (IECC) While both ASHRAE and the IECC use the same climate zone map for the (see Figure 1), the Insulation requirements in each climate zone for the two documents vary. In addition, both ASHRAE and the IECC provide two Compliance paths performance (max.)

2 U-factor) and prescriptive (min. R-value). The requirements for those paths are listed in Tables 1 and 2, for both wall and roof assemblies. NOTE: for the specifi c requirements currently adopted in each state go to: In addition, the calculated U-factors for some typical wall and roof assemblies, using Owens Corning s Certifi ed R, MBI Plus, OptiLiner and ELAMINATOR Metal Building Insulation products and systems, are provided for your convenience (Tables 3 and 4).
