As we publish this volume, I look forward to the next Symposium on Durability of Building and Construction Sealants and Adhesives (2008-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 feedback 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 2005 session chairpersons, the peer reviewers, and the staff of ASTM and AIP, who all helped to make the 2005 symposium and the publication of the associated papers possible.
