Historic Windows: Managing for Preservation, Maintenance, and Energy Conservation

Detailed Seminar Agenda

Seminar Overview

Historic windows are both critical components of a building’s weather envelope and valuable character-defining features worth retaining for architectural and environmental reasons. Learn about the rich history and variety of wood, steel, and aluminum windows and construction methodology. Explore the maintenance and rehabilitation techniques that allow windows to have long and sustainable service lives. Review energy conservation and economic issues as factors facing managers in the restore-or-replace debate and regulations relating to preservation of these assets.


Gordon H. Bock, principal, National Archives Associates; contributing editor Traditional Building; former editor-in-chief, Old-House Journal; architectural historian, writer, editor, and co-author of The Vintage House
