As we publish this volume, I look forward to the next Symposium on Dura­bility of Building and Construction Sealants and Adhesives (2014-DBCSA) and the associated flurry of papers in this dynamic industry. I encourage all readers to participate in the work of ASTM C24 committee, to attend the future symposia, and to contribute new papers. Your participation and feed­

back help to advance the industry and, as a result, we will all benefit from improvements to our built environment.

In closing, I would like to gratefully acknowledge the outstanding quality of the contributions made by the authors as well as the dedicated efforts of the 2011 session chairpersons, the peer reviewers, the staff of ASTM and AIP, and the Associate Editor of JAI, who all helped to make the 2011 sym­posium and the publication of the associated papers possible.
