The
unique identity of the Frederick Town Historic District
derives from the character of its buildings that offer visual
interest and variety within a generally consistent collection
of building elements. These elements include features such
as windows and shutters, porches, roofs, and cornices.
Windows
A window is a glazed opening in the wall of a building that
was historically used to admit light and air. It is usually
fitted with a frame that supports one or more operable or
fixed sash containing panes of glass.
-
All existing window assemblies should be preserved, with
their defining elements repaired rather than replaced.
- The
functional and decorative features of the windows that
help define the building's historic character should be
identified, retained and preserved. These features include
but are not limited to frames, sash, muntins, glazing,
sills, heads, hoodmolds, lintels, and paneled or decorated
jambs and moldings. Those deteriorated elements that cannot
be salvaged can be selectively repaired. If the element
is deteriorated beyond repair, it can be selectively replaced.
|
The distinctive shape and decorative features (including
shutters and hoodmolds) help define a window's architectural
style and character. |

- Instead
of replacing original glass with double-glazing, thermal upgrade
should be achieved by installing or replacing inadequate or
damaged weather stripping and caulking. The installation of
exterior storm windows is another appropriate option for obtaining
energy efficiency. Care should be taken to match the mullions,
muntins and meeting rails, size and configuration of the storm
to the primary window. All storm windows should be painted to
match the building's trim color.
- Replacing
multi-sashed windows with a single span of glass is not appropriate
nor is replacing a multi-light sash with a single span of glass.
- The use
of mirrored or tinted glass is not appropriate and is to be
avoided.
- If decorative
elements are missing, those elements should not be recreated
unless strong pictorial, historical or physical documentation
exists.
- If replacement
becomes necessary due to severe deterioration, the windows should
duplicate the existing material, design, configuration and hardware.
Replacement windows should have true divided lights with the
style and size of the muntins to match the original window.
False muntins and vinyl windows are not appropriate. For non-character-defining
elevations, leniency might be considered for replacement windows.
