Double-Hung Windows FAQs

What are double-hung windows?

Both the top and bottom panes in double hung windows are capable of operating independently from each 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! You’ll enjoy year-round savings on heating and cooling costs with the SolarZone™ TG2 Elite™ insulated glass package. During the warmest months of the year, it helps reduce solar heat gain, minimizes interior glare, and lowers interior glass temperature. In cools weather, it delivers outstanding thermal performance to keep your home warm and cozy. This package 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.

I am a Business owner and I understand the level of quality that needs to be taken with each customer. I couldn’t be any happier with the overall results of my windows and front door being installed, Couldn’t recommend them anymore—10 stars!
Dwight K.
These guys did a super job. I will hire them again without getting competitive bids which were a waste of time. They know what they’re doing, they delivered on time, on budget, and surpassed expectations. The office staff was always accessible; and the representative who came to provide the estimate and do the measurements was knowledgeable and listened to my requirements. I would recommend these folks to anyone, they did that good of a job.
