Case Studies in Accurate and Efficient Historic Window Replication

When restoration of existing fenestration isn’t feasible, design professionals and other stakeholders can turn to the latest innovations in historic window replication. This course will detail how and why WINCO engineering teams successfully design and fabricate historic replication windows that meet the standards of local Landmark Commissions, National Park Service, State Historic Preservation Officers, and building owners. California case studies that include some of our most recent iconic historic rehabilitation sites (such as Pier 70, the Kelly Cullen Building, Acheson Commons, Folsom Prison, and Ida B Wells HS), this session will illustrate the circuitous path that revitalization projects often take. You will learn how replicated windows can be fabricated in a way that makes it difficult to identify which windows are existing and which are new.

You Will Be Able To...

  1. Describe the process of copying historic windows from a manufacturer’s perspective.
  2. Identify local and national landmark historic projects, both completed and ongoing, for which unique historic window systems have been devised which celebrate the legacy of landmark structures.
  3. Discuss and weigh various considerations (such as seismic, blast, acoustic, energy, security, and building function) that go into the design and engineering process for creating authentic historic replication windows.
  4. Examine the latest technology and in the trenches work, including 3D scanning and printing and old-school field hand drawings for modeling and manufacturing replicated windows.
