The International Codes published by the International Code Council (www.iccsafe.org), are the most widely used model codes in the history of US construction codes. In addition to their widespread use throughout the 50 US states, numerous federal agencies - including the National Park Service and the US Department of Defense, have adopted the International Codes. Adoption of the ICC codes is also starting in other countries, particularly in the Middle East. This article summarises some of the major requirements set forth for windows, doors and other fenestration products in the 2012 International Energy Conservation Code. It should be noted that manufacturers who sell products in several states should be aware that, at this point, multiple editions of the International Codes are being enforced by various US jurisdictions.
