Single Hung vs. Double Hung Windows: What’s the Real Difference (and Which One Belongs in Your Home)?

Ah, the age-old debate in the world of windows:
Single hung or double hung?
It's right up there with vinyl vs. aluminum, or whether a ceiling fan should spin clockwise or counterclockwise in summer (spoiler: it's counterclockwise).

At Windoor Retro Professionals, we get this question every week. So let’s unpack it once and for all—without making it a turf war. Each window type has a purpose, and we’re not here to crown a winner. We’re here to help you make the right choice for your home.

🪟 Single Hung Windows – The Steady Workhorse

A single hung window has two sashes, but only the bottom sash moves—the top is fixed in place. Think of it like a one-way street for airflow.

Benefits:

• Lower cost than double hung windows... most of the time (depends on series with manufacturer).
• Fewer moving parts, which means less maintenance
• Great for rooms with limited vertical space (like bathrooms or kitchens)
• Slightly more energy-efficient due to fewer opportunities for air infiltration

Best For:

• New construction homes trying to stay on budget
• Rental properties where simplicity is key
• Ground floor installations where cleaning the exterior isn’t a hassle

When to Think Twice:

• Second-story installations (cleaning the fixed upper sash can be tricky)
• If you want maximum airflow and circulation
• If your building code requires egress options through the window (important in bedrooms)

🪟 Double Hung Windows – The Flexible Favorite

Double hung windows feature two operable sashes—both the top and bottom slide up or down. They offer versatility and are favored in many traditional home designs.

Benefits:

• Better airflow – open both sashes to create natural ventilation (warm air out the top, cool air in the bottom)
• Easier to clean – many tilt inward for safe interior cleaning
• Offers more design flexibility in historic-style or colonial homes

Best For:

• Second stories or multi-story homes
• Homes with children – you can open the top sash only for safer airflow
• Allergy sufferers – better airflow and indoor air exchange

When to Think Twice:

• You’re on a tight budget – they cost more than single hung
• You want a window with fewer parts to maintain or repair
• You live in a coastal or high-wind zone where more moving components = more sealing responsibility

💡 So… Which One Should You Choose?

Let’s break it down for Florida homeowners in particular.

Choose Single Hung Windows if:

• You're building new construction or remodeling on a budget
• You want low-maintenance, simple operation
• You want highest energy efficiency possible
• You live in a one-story home or don’t mind exterior cleaning

Choose Double Hung Windows if:

• You’re on a second floor and want to clean from the inside
• You prioritize ventilation and flexible airflow instead of energy efficiency
• You want a classic look and more control over how air moves in your home

⚠️ Florida Bonus Tip: Consider Impact & Energy Ratings

Whether you choose single or double hung windows, don’t forget that in Florida, performance matters just as much as design.

Be sure to ask:

• What’s the DP (Design Pressure) Rating?
• Is it impact-rated for hurricane zones?
• What’s the U-factor and SHGC for energy efficiency?
• Is the frame reinforced and sealed properly for wind load zones?

We install both styles using top brands like PGT, Simonton, Eastern Architectural Systems, and CWS by Pella—all built for Florida’s strict codes and wild weather.

🔧 Final Thoughts from Joe

Whether you go single or double, hung windows are one of the most popular choices for Florida homes—and for good reason. They’re versatile, attractive, and meet code when installed right. But understanding the difference in operation, cost, airflow, and maintenance can help you make a decision you’ll be happy with for years.
