International Codes can be confusing. The 2012 International Energy Conservation Code (IECC) includes new standards for almost every component in the building envelope, and these standards are further increased in the new International Green Construction Code (IgCC), which serves as an overlay code.

In an effort to assist building designers and contractors, the Center for Environmental Innovation in Roofing and the Polyisocyanurate Insulation Manufacturers Association and have published a Roof and Wall Thermal Design Guide for building professionals. Dr. James Hoff of the Center will host a webinar explaining the new guide on Dec. 18. Click here to register and receive a free electronic copy of the new Roof and Wall Thermal Design Guide.
