What is a Double Hung Window?


A double hung window is a vertical window that has two operable sashes. The two main benefits for this operating style are: maximum circulation - with the ability to open both sashes, and tilting - where the upper and lower sashes tilt inward allowing both the interior and exterior glass to be cleaned from inside your home. This is especially helpful for second and third floor windows.

Comparing Double Hung Windows Vs. Single Hung Windows

Instead of having two operable sashes, a single hung is a vertical window that has a fixed upper sash and an operable bottom sash. The amount of air ventilation is more limited with a single hung since only air comes through one opening, and it can be challenging to clean the outside of the upper sash on the 2nd or 3rd floor of your home since the single hung doesn’t come with tilt sashes

Here is a side by side comparison for a quick review:                                                                                                          Single Hung vs Double Hung Window Features      

How to Operate the Tilt Sash Function on a Milgard Double Hung Window:

Operating the tilt sash function on a Milgard double hung window is easy. Follow these step-by-step instructions:

  1. To open the window, lift up the SmartTouch® lock and slide to open the bottom or top sash. 
  2. Locate the two tilt latches on the top of the bottom sash.
  3. Slide the latches inward toward the center of the sash and pull towards you to disengage the sash from the frame.
  4. To operate the top sash, rotate the bottom sash downward until it rests against the bottom sill.
  5. Using the pull rail on the upper sash, pull downward until the bottom of the top sash is approximately 6” above the open bottom sash.
  6. Tilt the top sash inward. You may rest the top sash on top of the open lower sash.
  7. To re-engage the sashes with the jamb, rotate the upper sash until the tilt latches click back into the jamb track.
  8. Push upper sash up until it stops in the closed position.
  9. The top sash must be fully seated in the sash pocket for the locks to engage properly.
  10. Rotate the bottom sash until both latches engage in the track.

Other Window Operating Styles to Consider

In addition to the double hung window style, there are many other choices you can select to use in your home. Read on for information about casements, awnings, sliders and picture windows to mix and match:

Casement windows provide the maximum amount of air ventilation since the entire window is hinged at the side and opens outward. It looks like a picture window because unlike double hung or sliding window, a casement window has no rail (which can block your view).

Awning windows are similar to casement windows but, are hinged on top (instead of the side). These windows are generally smaller offering less air ventilation than a double hung or casement window due to their size.  They open upward allowing air flow into your home, but, blocking rain and leaves.

Horizontal Sliders

Horizontal Slider windows open with the sash sliding to the left or right (instead of up and down like the double hung and single hung window operating styles). Choose from a single slider where one sash slides or a double slider, where both sashes open. Either can provide great air circulation to a room.

For unobstructed views picture windows are ideal. Picture windows are fixed windows that do not open, making them perfect for difficult to reach places that will benefit from a natural light source.
