Double-hung windows are probably the most
common type of window. They open by sliding the
bottom half of the window up or sliding the top half
down. Because only half of the window area can be
open at one time, they provide less ventilation than
casement style windows. An advantage of double-
hung windows is they can be used to create air
movement in the home by opening the top portion of
the windows on one side of the house and opening
the lower portion of the windows on the coolest side
of the house. Air will naturally rise out of the higher
opening, pulling cooler air in the lower opening.
windows have weight-
and-pulley systems to

these systems tend to
stick or rattle and it is
hard to stop air from
leaking around the
pulley openings. Newer
models have spring-
tension devices and

You can make standard windows and doors
extraordinary with the creative use of window grids.
Grid patterns placed inside the glazing unit include
5/8" wide flat grids and 1-1/16" wide sculptured pattern
grids. Available for both our vinyl and fiberglass
windows, these internal grids make cleaning a breeze
both inside and out.
Additional grid options are available within our
fiberglass Ultra™ and WoodClad™ Series to produce
the effect of simulated divided lites:
Vintage Grids: Create the look of individual panes of glass on both the exterior and
interior of your fiberglass windows. This option provides the best simulated divided lite
Craftsman Grids: Create the look of individual panes of glass on the interior of your
fiberglass windows, leaving the exterior easier to clean.
Legacy Grids: Create the look of individual panes of glass on the exterior of your
fiberglass windows, leave the interior easier to clean.
Depending on the type of window you purchase, you have multiple options for the type of
hardware you can install. Whether you select our patent pending Positive Action Lock™
for your horizontal slider or single hung window, or select the optional fiberglass window
cam locks, you will be secure in the knowledge that our window hardware meets or
exceeds the toughest forced entry codes in the nation.

Stiff window treatments
There are many types of coverings apart from curtains
that can be used on windows to ensure privacy and block
Blinds are of the following types:
These let in plenty of light when drawn up, yet give complete
privacy when unrolled and let down. Roller blinds are made of
thick fabrics used in conjunction with rollers.
These are made of fabric attached to cords When the cords are
pulled, the blind rises up in accordion
pleats to form a pelmet. They are heavier
and warmer than roll blinds.
Venetian blinds These actually
originated in China, contrary to the
name. They are made of parallel slats of
wood, metal or plastic aligned
horizontally or vertically. They are
popular for their almost complete
control of air, light, and view.
Vertical louvre blinds
These are most effective on a large
floor-to-ceiling window. They work on
the same principal as the venetian
blinds except that they close across the
window rather than down
These are an inexpensive covering for
large windows. They are made from
fine strips of wood held together by
cotton, and let a pleasant, soft light
Shades may be of the following types:
Bamboo and woven wood shades
These were once considered rustic
and informal. They are available in
different weaves nowadays.
Fabric roller shades
These are inexpensive and can
be flexibly adjusted to cover as
much of the window as required
at a particular time.
Types of curtains
Curtains may be used to create various window treatments.
These are also called sheer or net
curtains and are usually made of
cotton or polyester.
Draperies refer to loosely hung
(not taut or stretched) soft
furnishings. These are made of
heavier fabrics and may be
These are usually made of
translucent or opaque fabrics
and are mounted on traverse
Casement curtains These cover
the entire window and have
casings at both top and bottom.

Curtain headings and accessories
We shall now look at the various headings and accessories
used with curtains.
Pelmets and cornices
Cornices are box-like shapes
used at the top horizontal
portion of the drapery treatment
to hide the poles and other
These are made of fabric that has been pleated, scalloped or ruffled.
They should never exceed one-sixth of the window's height and
should be about 8-12 inches in depth.
These are the appropriate hardware to use where
installations have to be flexible.
Traverse and decorative rods
These are used in conjunction with runners, which are hooked onto
the curtain. They come in many types. The conventional traverse
rod is used with classic pleated draperies that pull away from the
centre to either side.
Curtain rods are a very old curtain-hanging tradition.
They come in many beautiful and durable designs, with
a wide range of length options. Spacers in curtain rods
extend outward from the wall for depth or to
accommodate multiple rods. Both rod-pocket and tab-
top curtains can be difficult to open or close on
telescoping curtain rods. While hidden by many
medium-weight and heavyweight materials, rods are
visible through sheer curtains, and ring-top curtains
often allow the rod to remain visible. Decorative rods
may be best in these instances.
FinialsFinials are decorative ends of curtain rods. They
come in many styles and finishes, with different
shapes, such as scrolls, leaves, fleur-de-lis and
decorated oval or balls. They are available in brushed
silver, copper and poly-resin finish. Because they are
often the part of your window treatment that are
most seen beyond the curtain, it is good to have them
stand out but also to have them complement or
match your other room décor.
Curtain rings are attractive and easily attached to
your curtains or drapes. They slide easily along a
curtain rod without having to pull open a telescope
rod, making it easier to open and close your drapes.
Curtain rings are available in many sizes, shapes and
qualities, so shop around for the style that best meets
your design needs.
Tiebacks are soft loops of fabric, cord, chain or other
material that holds back drapes. They tie around the
drape itself, either centering it or pulling it off to the
side and tying it to a vertical rod. This allows a bigger
view outside and more natural light to enter the
room. Tiebacks are extremely common in curtains
and drapes that do not use rings, since those are hard
