- Joinery: Traditional windows utilize mortise-and-tenon joints, which can be dismantled, repaired, and reassembled without compromising the structure.

The Energy Efficiency Myth
A common argument for replacing historical windows is energy savings. However, information from organizations like the National Trust for Historic Preservation suggests that a well-kept historic window matched with a high-quality storm window can achieve thermal efficiency almost equivalent to a new double-pane window.
