of Replacement Windows
Replacement windows can increase resale value and energy efficiency. Several
types of typical windows are listed and discussed here.
Wood windows were used from the early 1900s to the present but became less of a
mainstay of the industry in the 1960s. They are prevalent in the Northern United
States. Steel and aluminum casements and Steel Vertical Operators were used from
the 1950s through the 1960s. Aluminum windows were used in the 1960s through the
present. Vinyl Replacement windows were established in the 1970s through the
Wood Windows (historical styling)
Wood "drop-in" replacement windows and vinyl windows are designed to sit in
place of the existing sashes and are constructed at 3 1/4" thickness in most
cases. These type windows sit in the opening where the top and bottom sash
originally moved in their respective wooden "tracks" The stop between the two
sashes must also be removed in this type of refurbishment or retro fit
installation. It requires minimal movement of existing trims both inside and
The alternative is to replace the entire wood window including jambs. This
requires the reworking of interior and exterior wood trim to accommodate the
size of the modern wood window. Modern wood windows are available in with 4
9/16" jambs as a standard feature but can be equipped with "jamb extensions" to
extend to 5 1/4" or 6 9/16". This is to accommodate the wall thickness as
Modern windows have two panes of glass. This has been the standard since the
Modern windows of 2009 can have two or more layers of glass. And the Energy Code
sets certain standards for performance of products installed in homes. These
codes now require Low - E Glass in all residential homes.
Low-E is a film that is multiple layers of metal poured microscopically thin over
the surface of newly poured glass. This heat reflective film is transparent but
can be darker or lighter depending on the type and manufacturer. This data is
rated in Visible Light Transmission. Darker glass with heavier Low - E will have
less VT. The NFRC Rates most energy star rated window manufacturers.
Modern windows also have optional gases between the
panes that have higher insulative qualities
than air, such as argon or krypton
Most Vertical Operators (Single and Double Hungs) now feature "tilt-in" sashes
for cleaning of the exterior surfaces. The industry moved towards this approach
for service and replacement reasons as well as accessibility to the exterior
from the inside of the home.
All Casement windows are hinged on one side and are typically operated using an
interior hand crank. Awning windows hinge on top and bottom
Sliding windows, or "sliders", are sometimes used in openings that are wider
than they are tall.
Non-operable or "fixed" windows also called "Picture Windows" are common in
the largest openings.
Retro-Fit replacement windows are custom manufactured to fit openings.
