"The '2012 International Residential Code Commentary,' Volume 1 is much more than a codebook; it's an in-depth look at the code's real-world applications and a powerful reference tool designed to provide a solid foundation in its uses. The book's approach is unique; it pairs the text of the code with valuable commentaries that instill a deeper understanding of its provisions. From technical requirements and illustrations to discussions of its practical implications and consequences when not followed, coverage is complete and detailed, but never overwhelming. In fact, Volume 1 focuses solely on the regulations contained in chapters one through 11. Volume 2 ... offers a unique combination of technical requirements, via the text of the code, and real-world applications, via valuable commentaries that accompany each section of text. The result is an impressive learning and reference tool that addresses the 2012 IRC, its practical implications, and potential consequences when it is not followed. This second volume covers the provisions contained in chapters 12 through 43, completing the two-volume set."--From publisher description.
