20 Types of Windows + Pros, Cons, and Average Installation Cost

This might sound unexpected, but there are more types of windows that you think. You may notice that as soon as you start renovating your house and replacing your old windows with the new ones – with tons of options, it’s sometimes difficult to opt for the ideal one.

However, it’s important to mention that each window type serves a different purpose and that their prices vary. The average cost of the window usually depends on its type, frame material, and the glass, but there are also the installation costs that you shouldn’t forget. It’s vital to find a credible and trained team of glass repair technicians that will do the work properly – otherwise, even the best windows will be a waste of money.

This article will deliver the most important information about window styles and their strengths and weaknesses. That way, you’ll learn more about the topic and choose your replacement windows more wisely.

Main Types of Residential Windows

Before you start looking for a specific type of window, you should know whether you need one designated for new construction or replacement. Windows for new structures have a nailing fin, which is a rim that allows you to secure the windows in an existing frame in the rough wall opening.

Replacement windows, on the other hand, are secured in an existing frame with fasteners that run through the window assembly. That way, you can install them much easier. Windows can also be operable (you can open them) and fixed (you can’t open them).

A Window’s Anatomy

The jargon used in the windows industry may sound intimidating if you haven’t had the opportunity to use it before. Therefore, we’re going to present the basics of the window’s anatomy so that you can have it much clearer:

  • Head jamb: The main vertical part that forms the very top of the window frame.
  • Grilles between the glass (GBG): These are color-matched grids installed between glass panes. They are attractive and easy-to-clean options.
  • Glazing: It’s a part of a window that’s made of glass.
  • Sash: It’s a movable part of a window that holds the glass panes together.
  • Stile: It is the main vertical member in the framework of a sash.
  • Rail: Rail is the horizontal piece of a sash, and it comes as the upper rail and the lower rail.
  • Sill: A window sill is a surface at the bottom of a window.

You’ll find other window-related terms depending on the window type that you choose, but the words mentioned above are the most common ones, and you’ll see them quite frequently.

We can move on to the specific windows types and their features.

20 Different Types of Windows: Specs, Pros, and Cons

Each house window type has its own specs and purposes, and you should choose one based on its appearance and primary functions. Think about whether you want them to be operable or fixed, the amount of light they let in, and if they are easy to be maintained and cleaned.

Here are the 20 most common types of windows you may consider:
