Different Types of Replacement Windows: A Primer

by miklesfamilyfarm on February 8, 2017

If your old windows are worn out, damaged, or drafty, you may be planning to swap them out for some newer, more efficient models. And that’s a great idea. But before you swap out your old windows for newer versions in the same style, why not read up on all of the different types of windows available? You just might find that another type of window suits your requirements more than the type you’ve got.

Let’s take a look at some popular window designs:


This design is suitable for places where the window is never opened, or where you want to make the most of the view. There are two types of designs under this category: one features several small frames within an overall window frame. The other design has a single large glass pane, and offers a clear view of the outdoor area. This view can look like a framed picture that give this type of window its name.

Slider or Glider

It is a popular replacement windows choice in modern homes, especially in high-rise apartments. Slider windows feature two or more glass sashes which can slide horizontally to both left and right. While the space-saving design works well for many, the opening of these windows will always be at least partially covered; as a result, it doesn’t offer as much ventilation as some other window types.


These windows are hinged, and open outward. Because casement windows open completely, they offer great ventilation. But in order to open outward, casement windows also require open space outside, immediately in front of the window.

Single Hung

In this type of window, there are upper and lower sashes. The top sash is fixed while the bottom one can be raised to open and close that part of the window. Like slider windows, single hung windows are good choices when space is at a premium and when great ventilation is not a priority.

Double Hung

Both the top and bottom sashes of a double hung window can be lifted. These windows have the added benefit of sashes that can be tilted in to provide better ventilation and easier cleaning.


Similar to casement windows, these hinged windows open outward. Because awning windows are hinged at the top, they open upward to provide some protection against the rain. This page contains an excellent description of why awning windows are so popular.


In this window design, there are several blades that pivot and tilt at the same time. Louvre windows are perfect for bathrooms and other places where free flow of air is needed but the view must be at least partially blocked.


Similar to awning windows, these hinged windows open outward. Unlike awning windows, these are hinged at the bottom. Because the entire sash can be tilted open, hopper windows provide great ventilation. They’re a popular choice for bathrooms and basements, as they can help these rooms to release humidity.

Tilt & Turn

These large windows are able to perform two distinct functions. Swing them in like a door to provide additional access or tilt in the top of the sash to provide additional ventilation.

Bay & Bow

Both of these windows types are actually a combination of three or more windows – a large central window flanked by smaller windows on each side. Bay and bow windows extend outside the home, which serves to open up the view and to provide extra shelf space inside the home.


These windows are installed above doors or large window. Transom windows are intended tolet the daylight enter the room even while the windows or doors immediately below them are closed


These windows are placed in the roof in order to let more daylight into the room. Skylights can have open or fixed designs; in the open design, the window can be opened for ventilation, while in the fixed design the window is installed for lighting purposes only.


This window’s purpose is to provide an escape route from a room in the event of a fire or any other emergency where the door cannot be used.

No matter which type of windows interest you, it’s a good idea to consult a professional window installer before making a final choice. Installers have the expertise to help you choose the best window; they will also be familiar with local building laws and any restrictions on the type of window that can be used.
