Double-Hung Windows FAQs

What are double-hung windows?

This classic window style allows for both the top and bottom panes of the window to move up and down, operating independently.

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.

My windows came out beautiful! I can’t thank Window World enough. From the initial estimate all the way to installation, their customer service was impeccable! I definitely would recommend Window World to anyone!

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.
