Association for Preservation Technology Delaware Valley Chapter

The Delaware Valley Chapter covers the state of Pennsylvania and Southern New Jersey. The goal of the Delaware Valley Chapter is to encourage better quality restoration and preservation by promoting good communication between the various individuals involved in these fields. We endeavor to accomplish this is by inviting speakers to give presentations or tours that will increase each member's knowledge and understanding of proper usage of types of products and processes in the construction industry.

The Delaware Valley Chapter was formed in 1984 and now has approximately 130 members. Events are held approximately once a month. A cross-section of the membership attends events. Location varies by event.
