The double-hung window, classic in appearance,
offers excellent control of ventilation. You can
raise the lower sash or lower the upper one
A casement window is hinged on one side and
swings out when you turn a crank (some are
inward-swinging). Because it opens fully, it
affords good ventilation and is easy to clean
6
A slider. It's made from two separate sashes-one
is fixed, the other slides in a track. Half opens
for ventilation. A slider is easy to operate and
most types are particularly weather-tight.
Jalousie or "louvered" windows are excellent for
ventilation but poor insulators-they leak a great
deal of air.
7
An awning window hinges at the top and tilts out
at the bottom, providing partial ventilation.
These are often used above doors or other
windows.
A hopper window hinges at the bottom. A hopper is
normally used for ventilation above a door or
window, where protected by eaves

Types of Windows

• Inoperable Windows
• Bay
• Bow
• Picture
• Geometric Shapes

A bow window is made from several windows
positioned side-by-side to create an arcing form.
Similar to a bay window, it provides drama in a
room
The bay window, made from a central sash and two
angled side sashes, is a classic favorite for
expanding a room with light, views and drama.
Angled side windows are often operable casements
or double-hung windows.

Round-top and other geometrically-shaped windows
are used as architectural accents.
