Windows – Styles: Casement vs double hung
In the world of windows there are many options to consider: style — casement vs double hung, material — vinyl vs wood, and glass — single vs double pane among others. In this first of three articles on windows we will define each of the primary window styles. Although double-hung and casement windows are the most common there are several other styles that are used.
- Double-hung — A double-hung window has two vertically sliding sash in a single frame. Double-hungs lift open while remaining flush with the wall, making them ideal around patios, decks and walkways. Double-hung windows look best when they are about twice as tall as they are wide and each sash is an equal-sized square. They are often installed in traditional or Colonial style homes.
- Single-hung — A single-hung window offers all the features and benefits of double-hung windows, with one difference: only the bottom sash opens by sliding upward.
- Casement — Casement windows are hinged windows that, with a turn of a crank, open outward to the right or to the left. Casements are common above kitchen sinks for areas where full venting windows are desired, and give you flexibility to group in stunning combinations. Casement windows offer more ventilation than double-hung windows, typically have less air leakage than other window styles, and look best if they are at least slightly taller than they are wide. Because they swing out, however, they may not be well suited to installation adjacent to heavy pedestrian traffic areas, such as decks or front porches.
- Awning — Awning windows are hinged at the top and open outward. Because of this design, awning windows shed water away from the window opening. They catch breezes from the left or right and are often used above, below or alongside stationary windows. They are a good choice for windows that are wider than they are tall.
- Gliding or Sliding — Gliding windows feature two sash, with at least one of the sash sliding horizontally past the other. They give you the advantages of double-hung windows with a more contemporary look.
- Picture or Fixed — Stationary windows, as the name states, are windows that don’t open. Often referred to as picture windows, they’re typically used to provide maximum light and an unobstructed view, and are often combined with venting windows.
- Transom — Like picture windows, transoms are most often used in combination with other windows, and can be either vented or fixed units. They are typically installed on top of a room’s primary windows. They help give a room the illusion of larger windows, allow in more light and, if vented units, may increase airflow. Transoms often are used to create a window wall.
- Specialty — Specialty windows are stationary windows characterized by their special shapes, including curves and dramatic angles. They can make a signature statement in your home and provide a delicate lighting accent.
- Bay & Bow — 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. All the windows can be stationary (fixed), operating (venting) or any combination of those. Both bay and bow windows provide great open views, as well as give a room the aura of being larger than it really is.
In our next article we will discuss the different materials used to make the window sash and frame.
