Casement vs Double Hung Windows: A Comprehensive Guide


Choosing between casement and double hung windows for your home can be challenging. Both window types have their unique features, advantages, and potential drawbacks. This guide aims to make your decision process easier by providing an in-depth comparison of these two popular window types.

What are Casement and Double Hung Windows?

Casement Windows

Casement windows, often referred to as crank windows, are hinged on one side and swing open horizontally, much like a door. They operate using a crank mechanism located on the interior side of the window, which pushes the window open and shuts it. An interior latch ensures the window is fully secure when shut.

Double Hung Windows

Double hung windows, on the other hand, have two sashes - an upper and a lower one - that slide vertically. Both sashes are operable, and the upper sash can also slide up and down, offering more flexibility in operation.

Casement vs Double Hung Windows: The Key Differences

Type of Operation

The fundamental difference between casement and double hung windows lies in their operation. While casement windows swing open sideways using a crank, double hung windows slide vertically up and down.


Typically, casement windows are more expensive than double hung windows, often costing twice as much. The reason for this price disparity is the more complex mechanical operations involved with casement windows and the lower consumer demand for them.

Use and Style

Casement windows are known for their contemporary, clean look and work well with modern style homes. Conversely, double hung windows are often associated with traditional, classic styles, making them a great fit for vintage cottage-style houses or new houses that emulate an older look.

Energy Efficiency

Energy efficiency is another critical factor to consider in the casement vs double hung windows debate. Casement windows are known for their superior ability to limit air intrusion in your home, creating an airtight seal when latched. Double hung windows, while also energy-efficient, have a different seal operation that may allow for minimal air seepage along the top.

Pros and Cons of Casement and Double Hung Windows

When comparing casement and double hung windows, it's essential to consider both their advantages and drawbacks.

Casement Windows: Pros and Cons


  • Easier to operate due to the crank mechanism
  • Direct breezes into the home when correctly positioned
  • Form an airtight seal when shut and latched, enhancing energy efficiency


  • Normal window unit air conditioners do not fit; specialty A/C units required
  • The outward opening can be caught by wind gusts, potentially causing damage
  • Time-consuming to open and close multiple casements at once

Double Hung Windows: Pros and Cons


  • Lower failure rate due to fewer mechanical parts
  • Easy to clean with the swing-in style sashes
  • The lower sash can be closed for safety while the upper sash remains open for ventilation


  • More difficult to raise and lower, especially when out of easy reach
  • The lower sash may refuse to stay up over time due to wear and tear
  • The horizontal bar divides the view

Making the Right Choice

The choice between casement and double hung windows depends on various factors, including the style of your home, your preference for window operation, and your needs for durability, energy efficiency, and ventilation. Take the time to weigh these factors and consider your personal preferences to make the best choice for your home.


Whether you choose casement or double hung windows, both options can enhance your home's aesthetic appeal and energy efficiency. It's all about finding the right fit for your needs and style. Remember, the best window choice is the one that brings you the most satisfaction and value for your investment.
