Double-Hung Windows FAQs

What are double-hung windows?

The classic style of double-hung windows allows both top and bottom panes of the window to move up and down independently of the other.

Are double-hung windows energy efficient?

Yes! Save on heating and cooling costs year-round with the SolarZone™ TG2 Elite™ insulated glass package. In warm weather, it will reduce solar heat accumulation, minimize interior glare and lower interior glass temperature. In cool temps, it delivers outstanding thermal performance and warmer interior glass surfaces to maintain comfort in the winter. This package also meets all ENERGY STAR requirements.

How do you clean double hung windows?

Double hung windows from Window World are made with tilt-in sashes. This means both the top and bottom sashes can be tilted inwards to make it easy to clean both the interior and exterior of your windows.

To do this, you’ll want to follow these steps:

  • Unlock and raise your window about 2”.
  • Move the wash assist tabs so they’re between the sash and the frame.
  • Carefully pull the lower sash towards you and rest it on another object for support (be sure not to tilt it more than 90 degrees).
  • Next, you’ll want to lower the upper sash. To do this, slide the tilt latches to the top and lower the top window sash, leaving an inch or more of space between it and the lower sash.
  • Push the tilt latches inwards and tilt the upper sash inwards towards you, and rest it carefully on the lower sash.

Follow these instructions, and you’ll be able to properly clean and care for each and every crevice of your double hung windows.

What is the difference between single and double hung windows?

Both single hung and double hung windows have window sashes that slide vertically. On single hung windows, only the bottom sash can slide, while the top sash is fixed and static. On double hung windows, both sashes can slide as desired.

How are double hung windows installed?

All Window World double hung windows are installed by our factory trained installation team. This includes properly setting, leveling and caulking to ensure your new windows are a perfect fit. Find out more about our window installation process.

How do you open double hung windows?

For double hung windows, both sashes can slide and allow the window to open. To open the lower sash, simply unlock the sash and slide it upwards. To open the upper sash, you’ll need to unlock your lower sash, and gently lower the upper sash to your desired position.

How do you lock double hung windows?

To lock your double hung window, it’s important to check the alignment of your locks. Make sure that your upper sash is pushed all the way up and your lower sash is pushed completely to down so they’re fully sealed. This will allow your locks to be secured without any obstructions.
