Knox Heritage Window Guidelines for Historic Preservation

Why Historic Windows Are Treated Differently

When a house has age and architectural value, the window pattern, muntins, sash proportions, and even the depth of the trim can matter as much as the glass itself.

Preservation rules tend to favor repair, compatible materials, and careful documentation because once original sash or trim is removed, that detail is hard to recreate well.

A historic window issue is rarely just a glass issue, since rot, drafts, hardware wear, and paint failure often show up together and need a broader fix.
