What is Single Hung and Double Hung Windows?
A single hung and double hung window is two of the most common types of windows used in residential and commercial building construction. Understanding the differences between these two types of windows is crucial for selecting the right window for a particular project or home.
What is Single Hung Window?
A single hung window is a type of window that is hung with one sash and one frame. The sash is the movable part of the window that slides up and down, and the frame is the vertical and horizontal structure that holds the sash in place.
What is Double Hung Window?
A double hung window is a type of window that is hung with two sashes: one sash is raised and one is lowered. The sashes are typically symmetrical, with one hanging on the top and the other on the bottom.
Key Characteristics of Single Hung Windows
Single hung windows have the following key characteristics:
- The sash is hung on the side, which can lead to more noise and vibrations
- The sash is typically narrower and less durable than double hung sashes
- The window is often less expensive to manufacture and install
- The window has a lower opening point, which can make it less appealing to homeowners who value a smooth, opening and closing experience
Key Characteristics of Double Hung Windows
Double hung windows have the following key characteristics:
- The sashes are raised and lowered, which provides a smooth, opening and closing experience
- The window has a higher opening point, which can make it more appealing to homeowners who value a smooth, opening and closing experience
- The window is often more expensive to manufacture and install
- The window is typically wider and more durable than single hung sashes
Advantages of Single Hung Windows
While single hung windows have some advantages, they are generally not recommended for residential or commercial projects due to their limitations. Some of the key advantages of single hung windows include:
- Noise Reduction: Single hung windows are typically less noisy than double hung windows due to their single sash design.

- Wide Selection: Single hung windows are available in a wide range of styles, materials, and configurations, making it easier for homeowners to find a window that meets their needs.
Disadvantages of Single Hung Windows
On the other hand, single hung windows have some significant disadvantages. Some of the key disadvantages of single hung windows include:
- Noise and Vibration: Single hung windows can be noisy and produce vibrations, which can be a problem for homeowners who value a smooth, quiet living space.
- Limited Opening: Single hung windows have a lower opening point, which can make it more difficult to open and close the window.
- Less Durable: Single hung windows are typically less durable than double hung windows due to their simpler design.
When to Choose a Single Hung Window
While single hung windows are not recommended for most residential or commercial projects, they can be a good choice in certain situations. Some of the key scenarios in which to choose a single hung window include:
- Rustic or Farmhouse-Style Homes: Single hung windows are often used in rustic or farmhouse-style homes, where a more traditional, no-frills approach is desired.
- Historic Buildings: Single hung windows can be a good choice for historic buildings, where preserving the original design and materials is a priority.
- Casual, Simple Designs: Single hung windows are often used in casual, simple designs where a more straightforward, no-frills approach is desired.
When to Choose a Double Hung Window
Double hung windows, on the other hand, are generally a good choice for most residential and commercial projects. Some of the key scenarios in which to choose a double hung window include:
