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. 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

I ordered a whole house of windows from Window World. Products were delivered and installed when they said they would be. Great customer service. All the girls in their office were great and returned calls when they said they were going too. I have already put in my next order for a whole house of siding. Can not wait until its complete. Then I will be having my shed and fencing done from them. Wonderful company! Love the lifetime warranty.

It was a pleasure having our windows installed by Window World. Their prices are very reasonable and their work was neat, clean, and started and finished when promised and we are very pleased with the results. They installed 13 windows (2 that were new installs and had to be cut and fit not just replace a 6 foot sliding glass door that also had to be cut and framed. All done in 2 days by 2 men. AMAZING.

If you get overwhelmed with multiple quotes and sales pitches, give this company a chance and definitely visit the showroom. Installation team was thorough, fast and efficient. Finished the whole house windows replacement in one day. There are more expensive companies but with this one you really get the best value for your money.
