Replacement Windows: What Are We Really Getting?


Replacement of windows is one of the most common requests to be evaluated in historic districts. This presentation will look at the various levels of replacement and the resulting visual effects. Illustrations will be provided to demonstrate how material, manufacturer, and installation methods all affect how a window looks. Attendees will learn about what information is needed and reasonable to collect for a proposed window replacement in order to effectively judge how well it will meet their community’s standards.
