Similar to a casement window, but turned on its side, awnings have hinges on the top of the window. Due to size limitations these are typically used as accent windows in certain areas of the home.

Bay or Bow Windows

Bay and Bow Windows are three, four, or five windows ganged together. Typically the center units are pictures, with the outer units (flankers) being double hungs or casements. These windows protrude from the facade of the house, allowing a bright display shelf or cozy seat on the interior.


Casements are windows hinged on the side, and can be cranked or pushed out to vent. Traditionally used as accent areas (such as above a kitchen sink), casements allow for so much open glass they have become very popular across entire homes.

Double Hung

The most popular type of window, double hungs feature two separate sashes that each travel up and down on a track, passing over one another when the window is open and locking together when the window is closed.


Gliders are like a miniature sliding door, but used as a window. They can provide a large amount of light and ventilation.

Picture Windows

Windows that do not operate at all are called picture windows. They can be made to very large sizes allowing for lots of natural light and offering great exterior views.

There are a number of other types of windows that don’t fit into any of the other classes such as bifolds, multi-slides, folding, hoppers, or garden. Typically these are used in specific situations in the home where the design calls for something different.

Tilt & Turn

A tilt and turn window can both tilt inwards at the top, like a hopper window, or open inwards from hinges at the side. The swing open position brings in fresh air, while the tilt offers draft-free ventilation and rain protection.
