Double-Hung Windows FAQs

What are double-hung windows?

A classic look with a twist: with double-hung windows, the top and bottom sashes move independently of each other, allowing you to fully customize ventilation.

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.

What are the size dimensions of double-hung windows?

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

Does this window style provide long-lasting durability?

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.

How do you clean double hung windows?

Window World double hung windows are designed using tilt-in sashes, meaning the bottom and top sashes can tilt inwards to make it quick and easy to clean both the inside and outside 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.

What is the difference between single and double hung windows?

Single hung and double hung windows both include vertically sliding sashes. Single hung windows feature only one mobile sash, while the other sash is fixed in place. Meanwhile, double hung windows feature two sliding sashes, meaning you can open and close both the top and bottom window sash.

How are double hung windows installed?

All double hung windows from Window World of Central Alabama are installed by our team of factory trained professionals. Our staff covers everything including setting, leveling and caulking, ensuring that your windows fit perfectly and provide an air-tight seal. Learn more about our installation process.

How do you open double hung windows?

Double hung windows feature two sliding sashes, meaning you can open your window from the top or bottom. To open the bottom sash, simply unlock it and slide the sash up to the desired position. To open the upper sash, unlock the lower sash and carefully lower the upper sash to the desired position.

How do you lock double hung windows?

Before locking your double hung window, check the alignment of your locks. Ensure the upper sash is pushed all the way up and that the lower sash is pushed down until fully sealed. This allows your locks to secure with no obstructions.

I called Window World for an estimate and they sent Rhett to my home. He was great. The windows were installed perfectly without a hitch and were put in a month earlier than expected. I would absolutely recommend Window World to anyone. Thank you Window World!
Treva C.
Awesome quality windows installed in 2002. Still look brand new in 2020. I had a broken glass. They knew the serial number, the exact piece to replace, have ordered the part, and will come out and fix it, all covered in warranty. It just doesn’t get any better than that. Man I love a quality company with perfect customer service.
