C. WINDOWS AND DOORS
Window and door frames are in most
cases wood. Brick structures have stone
sills and brick lintels. In some cases
where synthetic siding has been applied
window trim has been covered. Many
structures in the distict have aluminum
storm windows. Some houses retain
wood framed storm windows.
Required
Original windows and doors shall be
retained including sashes, lintels, sills,
shutters, decorative glass, pediments,
hoods, and hardware. When deteriorated
beyond repair, they shall be replaced with
units and trim resembling the original.
Recommended
Wood frame storm win-
dows and doors painted to
match the original should
be used but should not
damage existing frames. If
new sashes or doors are
installed, the existing or
original materials, design,
and hardware should be
used. When metal storm
doors are used, they should
be painted, anodized or
coated to match the exist-
ing. When awnings are
used they should be of can-
vas material.

Appropriate types of
weatherstripping for
metal windows.
Weatherstipping is an important
part of upgrading the thermal
efficiency of historic steel windows.
The chart at right shows the
jamb section of the window
with the weatherstripping
in place.

Spring-metal comes in bronze, brass or stain-
less steel with an integral friction-fit clip.
The weatherstripping is applied after the
repaired windows are painted to avoid gal-
vanic corosion. This type of thin weather-
stripping is intended for windows in good
condition.
Vinyl strips are scored and folded into a “V”
configuration. Applied adhesive is necessary
which will increase the thickness of the
weatherstripping, making it inappropriate for
some situations. The weatherstripping is gen-
erally applied to the window after painting.
Closed cell foam tape comes either with or
without an adhesive backing. It is effective
for windows with a gap of approximately
1/4" and is easy to install. However, this
type of weatherstripping will need frequent
replacement on windows in regular use. The
metal sections should be cleaned of all dirt
and grease prior to its application.
This very effective type of weatherstripping
involves the application of a clean bead of
firm-setting caulk on the primed frame with
a polyethylene bond breaker tape on the
operable sash. The window is then closed
until the bead has set and takes the form of
the gap. The sash is then opened and the
tape is removed leaving the set caulk as the
weatherstripping.
Casement windows adapted the English tra-
dition of using wrought iron casements with
leaded cames for residential use. Rolled steel
casements (either single, as shown, or paired)
were popular in the 1920s for Cottage-style
residences and Gothic-style campus architec-
ture. More streamlined casements were pop-
ular in the 1930s for institutional and small
industrial buildings.
