Double-Hung Windows FAQs

What are double-hung windows?

This classic style of window allows top and bottom panes both to move up and down, independent of the other.

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.

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.

What Your Neighbors Are Saying

We recently had our windows and siding replaced by Window World and could not be more happy. Our initial meeting with Matt was very helpful, and in no way did he make us feel pressured with sales tactics. All of the guys on the work crew were great, always very polite, respectful and clean.
Dawn L.
Incredibly pleased with this company. We got quotes from multiple companies and Window World came in literally at a quarter of the price of one of the quotes with amazing quality. Would highly recommend to anyone in the market for windows!
Kelly S.
Recently used Window World to replace several windows in my house. Windows were in two weeks earlier than expected, which was AWESOME! The installers were great, very pleasant and professional and clearly knew what they were doing.
