The National Park Service will host a webinar on the application of Preservation Brief 16: The Use of Substitute Materials on Historic Building Exteriors, presented by Technical Preservation Services. This webinar will cover the recent guidance updates published in October 2023, including considerations for the appropriate use of substitute materials with case study examples.
The October 2023 guidance provides additional direction as well as technical preservation information on when a different material than the historic one may be appropriately used to replace a deteriorated or missing historic feature, consistent with the Secretary of the Interior's Standards for Rehabilitation.
The guidance on the use of substitute materials was updated to be more consistent with other NPS guidance and to ensure that it continues to reflect current and best practices. Revised guidance takes into account such factors as availability, performance, location/visibility, code requirements, and sustainability/resilience of the proposed new and historic materials or features. The guidance continues to recognize that flexibility may sometimes be needed when it comes to new and replacement materials as part of a historic rehabilitation project.
NPS is offering the same webinar on two different dates for increased attendance opportunity. Registration is free and open to the public – please select one of the dates and use the registration links below.
