Buying Replacement Windows? Get to Know Your Window Terminology

While window terminology isn’t particularly sexy, knowledge is. If you own a home, the more you know and understand about it, the better you can care for and maintain it. In addition, if you are looking to replace windows or build a new home, you need to know and understand all your options to make the best decision for this significant investment.

Window terminology you want to know

Whether you’re looking for new windows or simply want to get a better understanding of the windows you have, here’s some basic, helpful jargon.


horizontal slider

As the description indicates, this window scrolls horizontally from left to right. It can slide right-to-left or left-to-right, and sometimes even slide on both sides. This is the most common type of window in most homes.

Horizontal sliders are the most common type of window because they allow ventilation, are easy to maintain and do not take up extra space when open.


window terminology single hung double hung

Single- and double-hung windows are similar to horizontal sliders, except they slide vertically (up and down) instead of side to side.

A double hung window can be slid from above or below to open. In addition, they have a screen that fits over the entire window opening. These provide excellent cross ventilation. There is also a tilt function that makes cleaning easier.

Single-hung windows are the same as their double-hung counterpart, except they can only be opened from the bottom and there is only a screen on the bottom half of the window that opens.

Single and double top hung windows are also popular window styles. They are often used in bedrooms for security, while still providing ventilation as you can lock the bottom of a double top hung window and simply open the top. They are also often used side by side for excellent ventilation.


window terminology picture cat

A window is a stationary window that often shows a view. Image windows do not open and they have no screen. They do not provide ventilation. They are available with or without grids.

A window is usually combined with double or single top hung windows for unobstructed views and ventilation.

window terminology canopy cat

An awning window opens vertically and outwards, effectively forming an awning. They come in limited sizes and are not super common, although they do have their place.

Canopy windows are often used in rainy climates where you can leave your window open but keep the amount of moisture entering the house to a minimum.


window terminology casement cat

A casement window, similar to an awning window, also pivots and opens outward. The difference is that a casement window opens to the side. The advantage of a casement window is that it can be opened completely, providing maximum ventilation. The screen is on the inside of the house.

A casement window is useful where maximum ventilation is required or in damp areas of your home, such as the kitchen and bathroom.
