This classic window style allows for both the top and bottom panes of the window to move up and down, operating independently. Reinforced narrow silhouette frame and sash profiles make a statement of style with their low-profile design. The result is a beautiful and expanded glass area. At the same time, internal chambers increase structural integrity, rigidity and energy efficiency.

Yes! Our windows are ENERGY STAR-certified and equipped with low-E glass, to reduce solar heat gain and keep your interior temperatures more consistent and comfortable. Other energy-saving features include insulating gas between panes and a warm-edge spacer system.

Our double-hung windows are built to fit your home’s specific measurements. Contact us to learn size specifications of our different models.

Yes! When extreme wind and weather hit, our proprietary sill interlock stands strong. Traditional slope sill designs can allow the sash to bow during powerful winds, but with our interlocking sash-to-sill technology, the sash is channeled firmly into the window frame for a unified wall of strength.

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.

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.

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.

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.

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.

Yes! All Window World double hung windows are ENERGY STAR® Certified. Our windows are constructed with Low-E glass, warm-edge spacers, and insulated vinyl framing, all designed to optimize your window’s energy efficiency. Find out more about the energy efficiency of Window World windows.
