Double Hung Vs. Casement Windows

Comparing Two of the Most Popular Types of Windows and Selecting the Best Windows for Your Home

Are you in the market for new windows, but don’t know which type of window is best for your home? With all the different types of replacement windows available, choosing the best type of window for your home can be confusing. In this article, we will discuss two of the most popular types of windows – Double-Hung and Casement Windows.

Double-Hung Windows

Crawford Contracting double-hung windows open and shut vertically and come equipped with a fully operable upper and lower sash, which makes for easy cleaning and maintenance, both inside and out. They are also very easy to open due to a built-in spring-loaded balance system. Double-hung windows are very common in San Diego homes because of their practical and functional operation.

Casement Windows

Crawford Contracting casement windows open horizontally with a retractable handle or crank that effortlessly opens and shuts the window. Casement windows open to a 90-degree angle allowing great airflow and easy cleaning from inside your home. Casement windows are also very common in San Diego homes, but typically do not have the lifespan of double-hung windows because they have more moving parts.

Detailed Window Comparison

Window Screens

  • Double-hung windows have the screen on the outside of the window.
  • Casement windows have the screen on the inside of the window – Crawford Contracting casement window screens are custom ordered to match the interior window color.


  • Double-hung windows have a horizontal bar called a meeting rail in the center of the window that can potentially obstruct the view through the window.
  • Casement windows do not have any bars in the window to obstruct the view, which can be a deciding factor when it comes to choosing between these two types of replacement windows.

Energy Efficiency

  • Crawford Contracting double-hung windows have a snug fit within the window frame and typically provide great energy efficiency.
  • Crawford Contracting casement windows are the winner when it comes to energy efficiency due to the tight seal between the window glass and frame when the windows are shut and locked.

Window Glass

Both double-hung and casement windows are available with dual-pane or triple-pane glass and come equipped with “Warm Edge Technology“, which can help prevent window seal failure.

Window Cost

Generally, double-hung and casement windows are very similar in price. Factors that can increase or decrease the total cost for either of these windows include window frame material, type of glass, and window hardware. Because purchasing new or replacement windows is a huge investment for your home, we never recommend installing cheap alternatives to our high-quality windows.
