Single-hung and double-hung windows are two of the most common and timeless window frame types installed. Both have an upper and lower sash which separates the window both physically and visually.
But while they may look identical at a glance, there are a few key differences between single-hung and double-hung windows that impact the functionality and performance of each style.
Read on to explore the 6 essential factors you should consider when choosing between single- and double-hung windows for your Muscle Shoals home.
The most obvious difference between single- and double-hung windows is the number of operable sashes. A single-hung window has one operational sash—the top sash is fixed while the bottom sash can move and tilt inward. Meanwhile, a double-hung window allows both the top and bottom sashes to open and close while also tilting inward. As you will read, this one difference has a ripple-effect on the other factors.
Single-hung windows are typically the more affordable option of the two styles. This is because single-hung windows have less moving parts so they are easier to manufacture, and consequently, cheaper to install. That percentage difference may seem insignificant now, but the costs can quickly add up if you plan to purchase multiple windows.
However, cost alone isn’t the only factor to base your decision. Double-hung windows may be more expensive at face-value, but you should also consider other factors like performance and convenience. Differences there could help offset the initial higher cost.
Double-hung windows provide better ventilation than single-hung windows because both sashes are able to open. You have the ability to open either the top or bottom, as well as open both panels halfway at the same time to maximize circulation. When you do this, warm air from inside can escape via the top sash while fresh air can enter from outside via the bottom sash. In other words, the versatility of double-hung windows can help you cool down a room faster, giving it a slight advantage over a single-hung.
Single-hung windows are typically more energy-efficient than their two-hung counterpart because they have less moving parts to allow air infiltration—but double-hung windows from Window World of Muscle Shoals are designed to be just as energy efficient. Along with being ENERGY STAR-certified and manufactured with insulated glass and frames, our double-hung windows use weatherstripping to seal air leaks around the top and bottom sashes and prevent exterior drafts and moisture from entering your home.
Double-hung windows are easier to clean than their one-hung rival, leading to their rise in popularity. Both the upper and lower sashes tilt in so you can clean both the interior and exterior from inside your home.
On the other hand, single-hung windows require you to be inside to clean the interior of the window and outside to clean the exterior. The extra effort can turn cleaning day into a time-consuming and bothersome chore.
Since single-hung windows predate double-hung windows, they are more the more common style and often used on historic homes to retain an authentic look. They also are found on first floors or low-to-the-ground homes due to the difficulty it takes to clean both sashes.
Contrastingly, Double-hung windows are most often seen on modern or new homes because they are easier to clean and more versatile in design.
