Not
all windows look and work alike. Some slide, crank or swing open and
closed; others, such as picture windows, have no working parts. The
window frame, which encloses all the basic parts of the window, may be
made of wood, vinyl, or metal. Wooden window frames require painting,
but those made of vinyl or aluminum are nearly maintenance free.
Because metal conducts cold, wood windows are preferred in climates
with cold winters.
The most popular window style is the double-hung window. Get Free

- Double-hung
windows have an upper and a lower sash (the inner frame that holds the
glass panes in place) that move vertically in separate channels. The
sashes are separated by a small piece of wood called a parting strip.
The upper and lower sashes have meeting rails — that is, the top rail
of the bottom sash and the bottom rail of the upper sash meet and are
slanted and weatherstripped to form a tight seal between the rails. A
locking mechanism secures the sashes together at the two parting rails
to create a tight seal and to minimize air infiltration and heat loss.
- Casement
windows have hinges on one side of the sash and swing outward when you
activate a lever or crank. Because the entire casement sash swings
outward, these kinds of windows provide full ventilation and
unobstructed views. Casement windows are easy to open, so they're
commonly used where humidity or heat can build up, such as above
kitchen sinks, in bathrooms, and on walls that connect to porches.
- Sliding
windows open horizontally and bypass each other in separate tracks
mounted on the header jamb and sill.
- Awning
windows are hinged at top and swing outward via a crank or lever.
- Hopper
windows are hinged at bottom and swing inward.
- Jalousie
windows are made of a series of horizontal glass slats that are joined
so that all the glass slats open or close together when the crank is
turned. The drawback to jalousie windows is that the cracks between the
slats offer an avenue for air infiltration.
