Double Hung vs. Casement Replacement Windows

Installing replacement windows in Wisconsin means homeowners usually ask if they should invest in casement replacement windows or double-hung replacement windows to keep their home cool in the summer and warm during the cold winters.  There are advantages and disadvantages to both types of windows.  Here is what you need to know:

Both the top and bottom sashes open on a double-hung window. On double-hung tilt windows, the sashes tilt inward to enable easy cleaning of the exterior faces of both the top and bottom sash.

Since double-hung replacement windows open without using any interior or exterior space, they’re an excellent choice for small rooms or next to walkways, porches, or patios, where you don’t want a window to protrude.

Most new double-hung replacement windows use spring balances to support the sashes, but traditionally, counterweights held in boxes on either side of the window were used. These were attached to the sashes using pulleys of either braided cord or, later, purpose-made chain.


• Good for small rooms or areas where you don’t want a protrusion from the wall
• Traditional styling matches many older homes

• Convenient cleaning (tilt-in models)
• Depending on frame material can be difficult to open and close due to swelling

Casement Replacement Windows

A casement replacement window is hinged at the side and opens outward. It provides excellent ventilation—at times literally reaching out and catching the breeze. It looks like a narrow picture window because, unlike double-hung or sliding windows, it has no rail to obstruct the view.  casement replacement windows

Some casement windows are simply pushed open, but most have a hand crank. If you’re installing windows over a sink, countertop, or appliance, a casement replacement window with a crank can be the perfect solution (presuming that you can reach the crank handle to open it).

Of all the window styles that open, casement windows generally allow the least amount of air leakage—provided they are installed correctly.


  • good ventilation
  • ease of operation
  • less air leakage than other styles (if installed properly)


Casement replacement windows will protrude out onto patios and walkways and may create a hazard of people walking into them. Caution must be exercised when choosing a casement in these situations.
