In brief:
- Double hung windows have two operable sashes that slide vertically, giving independent top-and-bottom ventilation control.
- They balance classic style with modern energy performance when built with low-E glass, insulated frames, and tight weatherstripping.
- Installed cost generally runs in the $350 to $900 range per window, with performance depending heavily on installation quality.
A double hung window is a window style with two vertically sliding sashes, both of which can open independently to let air in from the top and bottom at the same time. This dual-sash design is why the style remains one of the most common choices in American homes, from older bungalows to newer builds that mimic traditional window lines.
For homeowners comparing window styles before a replacement project, a double-hung window provides a practical combination of airflow control, easy cleaning, and a design that complements many architectural styles. Homeowners exploring a Double Hung Window Lakewood CO can benefit from modern designs that allow both sashes to tilt inward, making it easier to clean the exterior glass from inside the home. This feature is particularly useful for multi-story properties where accessing windows from outside can be difficult.
How Double Hung Windows Perform in Colorado Conditions
Window performance ratings matter more than style alone when it comes to energy use. According to the U.S. Department of Energy’s window technologies guidance, heat gain and loss through windows is a major contributor to a home’s heating and cooling demand, making U-Factor and solar heat gain coefficient ratings important factors to check before buying.
A few performance notes specific to double hung units:
- Both sashes are operable, which creates more seams and potential air-leakage points than fixed or crank-style windows.
- Modern double hung windows close that gap with improved weatherstripping, multi-point locks, and insulated glass packages.
- Argon-filled double or triple glazing reduces thermal transfer compared to older single-pane glass.
Lakewood’s front-range climate brings intense summer sun, sudden hailstorms, and wide seasonal temperature swings, all of which put extra stress on window seals and frame materials over time. Homes with original single-pane or worn double hung windows in the area often show noticeable drafts or condensation between panes, a sign that the seal has failed.
Double Hung vs Other Common Window Styles
| Window Type | Ventilation | Energy Seal | Typical Installed Cost | Best Use |
|---|---|---|---|---|
| Double Hung | Top and bottom sashes open independently | Moderate, more seams than fixed styles | $350 – $900 | Traditional homes, bedrooms, living rooms |
| Casement | Full sash swings open via crank | Strong, compresses tightly when latched | $375 – $1,000 | Kitchens, bathrooms, hard-to-reach spots |
| Picture | None, fixed pane | Best, no moving parts | $250 – $750 | Scenic views, paired with operable windows |
| Single Hung | Only bottom sash moves | Slightly tighter than double hung | Generally lower than double hung | Budget-focused replacements |
These figures reflect general industry ranges reported in the 2026 energy-efficient windows buyer’s guide and can vary by frame material, glass package, and regional labor rates.
Choosing Frame Materials and Features
Frame material affects durability and upkeep as much as the sash style does.
- Vinyl frames resist moisture and require little maintenance, a practical fit for Colorado’s freeze-thaw cycles.
- Fiberglass frames resist warping under temperature swings and hold up well through hot summers and cold winters.
- Wood frames offer a traditional look but need more regular sealing and painting to prevent moisture damage.
Choosing between these materials usually comes down to budget, the home’s architectural style, and how much exterior maintenance an owner wants to take on.

Frequently Asked Questions
Are double hung windows energy efficient? Performance depends more on construction quality than style alone; modern double hung units with low-E coatings, insulated frames, and tight weatherstripping can perform well, though they generally have more seams for air leakage than fixed or casement styles.
How much does a double hung window typically cost installed? Installed pricing generally falls between $350 and $900 per window, varying with frame material, glass package, and local labor costs.
How long do double hung windows usually last? Lifespan depends on frame material and climate exposure, but well-maintained vinyl or fiberglass double hung windows commonly last several decades before seals or hardware need replacement.
What is the main advantage of double hung over single hung windows? Double hung windows allow both the top and bottom sashes to open, giving better airflow control, while single hung windows typically have a slightly tighter seal since only the bottom sash moves.
