There are several things to learn when it comes to understanding single-hung vs double-hung windows. In this guide, we’ll go over the cost difference, when to use which one, maintenance requirements, and more. Once you know the ins and outs of each, it makes it that much easier to choose which style will work best for your home and budget.
What Is a Single Hung Window?
A single hung window is one of the most common types of windows you’ll find in homes today. It has two sections, or sashes, but only the bottom one moves up and down. The top sash stays fixed, which makes the design simple yet very durable. When you slide the lower sash open, you get fresh air while the top part stays sealed tight, helping keep your home energy efficient. Because there are fewer moving parts, single hung windows often last longer and require less upkeep than more complicated designs. Homeowners like single hung windows for their clean, classic look and how easy they are to use. They fit well in just about any room, from bedrooms to hallways, and are perfect for areas where space is limited since they don’t swing outward.
Pros and Cons of Single Hung Windows
Pros:
- Classic and versatile design that fits most home styles
- Fewer moving parts means less maintenance
- Good energy efficiency because of a tight upper seal
- Often less expensive than double hung windows
- Easy to operate and long lasting
Cons:
- Only the bottom sash opens, limiting ventilation
- Harder to clean the outside of the top sash from indoors
- Less airflow control compared to double hung windows
- May not be ideal for upper-story windows where cleaning is difficult
What Is a Double Hung Window?
A double hung window looks a lot like a single hung window, but it gives you more flexibility. The main difference is that the top and bottom sections can move up and down, which means you can open either or both to control airflow. For example, you can open the top sash to let warm air escape and the bottom one to bring in fresh air. It also makes cleaning a lot easier since both sashes can tilt inward so that you can wash the outside of the glass from inside your home. They’re especially handy in rooms where you want good ventilation, like kitchens or bathrooms. The extra movement and control make them a great option if you’re someone who likes to have the windows open often.
Pros and Cons of Double Hung Windows
Pros:
- Both the top and bottom sashes open for better airflow
- Easier to clean since both sashes tilt inward
- Great for ventilation in kitchens, bathrooms, and bedrooms
- Offers more control over air circulation and comfort
- Fits well with both modern and traditional home styles
Cons:
- More moving parts can mean more maintenance over time
- Slightly less energy efficient than single hung windows due to extra seams
- Typically costs more than single hung options
- May require more frequent adjustments to keep the sashes operating smoothly
What’s the Cost Difference?
The cost difference mostly comes down to how each one is built and what features they include. In general, single hung windows are going to be more affordable, while double hung windows cost a bit more because of their added functionality. Several factors influence the overall price for both styles:
-
Design and Mechanics:
Double hung windows have two operable sashes, which means more moving parts and hardware. This extra engineering adds to both material and labor costs.
-
Materials Used:
Vinyl is typically the least expensive option, while wood or fiberglass frames cost more. The material choice can make a big difference in price for either style.
-
Energy Efficiency:
Single hung windows often have fewer seams and a tighter seal, which can make them slightly more energy efficient. Some homeowners choose to upgrade double hung windows with better insulation or glass coatings, which can raise the price.
-
Size and Customization:
Larger or custom-sized windows will naturally cost more to produce and install. Decorative grilles, special finishes, or unique shapes can also increase the price.
-
Installation:
Professional installation always adds to the total cost, and double hung windows can take a little longer to install because of their additional moving parts.
Key Differences To Consider
Maintenance
Single hung windows are generally considered fairly low maintenance. The fixed top sash means there are fewer tracks and locks to clean or repair, and the structure stays tight and simple. Most of the time, a quick wipe-down and an occasional check of the lower sash hardware are all that’s needed to keep them in good shape.
Because both sashes move on double hung windows, they require a bit more attention. Dirt and dust can collect in the upper and lower tracks, and the extra locks and tilt mechanisms sometimes need lubrication or adjustment. In short, single hung windows take less effort to maintain, but double hung windows make routine cleaning simpler and more comfortable.
Energy Efficiency
Both single hung and double hung windows are designed with energy efficiency in mind, but the frame material plays a big role too. Vinyl and fiberglass frames often have multi-chambered designs that help slow the
transfer of heat, keeping your home warmer in the winter and cooler in the summer. Fiberglass versions can even include optional insulating foam for an extra boost in comfort all year long. Wood windows also perform well because wood is a natural insulator, helping maintain steady indoor temperatures. In general, single hung windows tend to be slightly more efficient since they have fewer moving parts, which means less chance for air to leak in or out.
Installation
Both single hung and double hung windows can be installed in new construction homes or used as replacement windows during remodel projects. New construction installations typically involve attaching the window frame directly to the studs with a nailing flange before the exterior siding or stucco goes on. Replacement installations are a bit different since the new window fits into an existing opening. This means that accuracy and fit are especially important to prevent gaps or air leaks.
No matter which type of window you choose, a proper seal around the frame is key to keeping out drafts, moisture, and outdoor noise. During installation, installers use shims, which are small wedges made of wood or plastic, to make sure the window sits level, square, and secure within the opening. Once everything is properly shimmed and sealed, insulation and caulking are added around the perimeter to create a tight barrier.
Ventilation
Ventilation is another important factor to think about when choosing between single hung and double hung windows. Both types allow for fresh air circulation, but they do it in slightly different ways. With single hung windows, you can only open the bottom sash, which lets cool air flow in near the floor. This setup works well in rooms where you just need a bit of airflow or want to keep the upper part of the window closed for safety or privacy.
Double hung windows offer more flexibility since both sashes can move. You can open the bottom to bring in cooler air while opening the top to let warm air escape. This natural movement helps improve air circulation and can make a room feel more comfortable without relying as much on fans or air conditioning. Because you have more control over where the air comes in and goes out, double hung windows are often preferred in areas that need stronger ventilation, or rooms that get a lot of sun.
Size
Both styles of window come in a range of standard and custom sizes, giving you plenty of flexibility depending on your space and design goals. Double hung windows are generally available in larger dimensions, making them a great choice for rooms where you want to maximize natural light and outdoor views. Their balanced design allows for impressive sizes, sometimes as large as six feet wide by twelve feet tall. These larger windows can completely change the feel of a space, making it brighter and more open.
Single hung windows are typically smaller and more compact, which makes them ideal for bedrooms, bathrooms, or other areas where wall space is limited. They can be found in sizes as small as two feet wide by three feet tall, which helps maintain privacy and efficiency without sacrificing light.
Where To Use Single-Hung vs Double-Hung Windows
Single hung and double hung windows each tend to work best in different parts of the house. Single hung windows are great in spots where you want something simple and low maintenance, like above the kitchen sink or near a staircase landing. They’re also handy in basements or laundry rooms where you mainly want some light coming in rather than a lot of airflow. Double hung windows are more common in areas where ventilation really matters, like bedrooms or home offices, since you can easily open either sash to control air movement.
The Single-Hung vs Double-Hung Window Conclusion
