Types of American Windows and Doors

Double-Hung Window
A double-hung window has two vertically sliding sash (glass panels) in a single frame. Double-hung windows lift open while remaining flush with the wall, making them ideal around patios, decks and walkways. Both top and bottom sash tilt in for easy cleaning.
  Single-Hung Window
This style is the same as a double-hung window in appearance, but only the bottom sash opens for ventilation.
  Casement Window
Casement windows are hinged windows that open outward to the right or to the left. They’re common above kitchen sinks and give you the flexibility to group them in stunning combinations.
  Gliding Window

These windows feature two or three sash, with at least one of the sash sliding past the others. They provide the advantages of double-hung windows with a more contemporary look.

  Awning Window
Awning windows are hinged at the top and open outward. They catch breezes from the left or right and are often used above, below or alongside stationary windows.
  Specialty Window
Specialty windows are stationary (nonopening) windows characterized by their special shapes, including curves and dramatic angles. They can make a signature statement in your home or provide a delicate lighting accent.
  Hopper Window
Hopper windows open inward from the top.  They’re an ideal choice for basements, garages and attics.  Hoppers are great for areas with limited space that need ventilation.
  Bay or Bow Window
Bay and bow windows are window combinations that project outward from a home.  These dramatic combinations can add space, volume and light to a room and add more personality to any home.
  Gliding Patio Door
Gliding patio doors have at least one door panel that glides smoothly past another panel. When space is at a premium, gliding patio doors offer a convenient way to access your patio without having to worry about interior furniture placement or possible exterior obstacles.
