What Are Double Hung Windows?
Why You’ll Love Double-Hungs
Breeze Control Like No Other
Want cool air at your feet and warm air drifting skyward? Just crack open both sashes. It’s natural airflow made elegant.
Cleaning Without the Ladder Acrobatics
Many modern double-hung models tilt inward. Seriously—no more precarious balancing act to clean the outside glass. You do it all from inside, in socks if you like.
A Fit for Any Style
From charming cottages to sleek new builds, you can find double-hung windows in wood, vinyl, fiberglass, or even fancy aluminum-clad wood. They never look out of place.
Energy Savings Built In
Pick insulated glazing and quality weatherstripping, and you’ll notice drafts vanish and your heating bill tiptoe downward.
Safe Fresh Air
Worried about little ones or your curious cat? Open only the top sash to let in light and air—while keeping everyone secure.

What to Ask Before You Buy
- Exact Measurements Matter
Measure your rough openings twice (or have a pro do it) so you don’t end up with windows that need shims or worse—a redo. - Glass That Works Harder
Look for Low-E coatings and argon gas fills between panes. Your comfort—and your wallet—will thank you. - Grilles & Grids
Love that divided-light look? Choose between interior grilles or between-glass options. Both add charm; only one adds cleaning headaches. - ENERGY STAR® Seal
If efficiency is your goal, make sure your windows carry the ENERGY STAR® label for your region. - Installer Expertise
Even top-of-the-line windows can leak if not flashed and sealed correctly. A certified installer is worth every extra dollar.

Your Top Questions Answered
Can only the bottom sash move?
That’s a single-hung window—only the bottom sash lifts. Double-hung windows give you freedom on both top and bottom.
Are they truly energy efficient?
With the right frame and glazing, absolutely. Quality weatherstripping keeps heat in during winter and out in summer.
DIY install—good idea?
If you’re a seasoned DIYer, you might manage a basic replacement. But for warranty peace of mind and perfect seals, I’d call in a pro.
How often to check and maintain?
Give weatherstripping a once-over each year, and clean tracks twice annually. Your windows will reward you with smooth, quiet operation.
What’s their lifespan?
Expect 20–30 years or more—especially if you choose durable materials like fiberglass or clad wood.
Next time you slide open a double-hung window, enjoy that simple pleasure—knowing you picked a design that’s practical, beautiful, and built to last.
