Difference Between Single-Hung and Double-Hung Windows
What is a Single-Hung Window?
A single-hung or single-sash window has one movable sash. While the upper sash remains fixed, its bottom sash can slide up or down.
Single-hung windows have frames made using various materials, like wood, aluminum, vinyl and fiberglass. They can also be customized based on your preferences and design needs.
How Do Single-Hung Windows Work?
Single-hung windows are easy to operate. To open such a window, simply lift the bottom sash upward. Its vertical sliding movement allows control over the ventilation and airflow that enter the room. The fixed top sash provides security and stability. Its simple operation reduces the chance of mechanical failure.
Benefits of Single-Hung Windows
The perks of single-hung windows include:
- Cost-efficient: These windows have less moving parts, are easier to manufacture and are made using affordable materials.
- Energy efficient: These windows often come with double glazing, low-emissivity coating and even insulated frames which allows minimal heat transfer and optimum energy efficiency.
- Easy installation: These windows do not require operable parts which makes them easy to install.
Drawbacks of Single-Hung Windows
The downsides of single-hung windows include:
- Difficult to clean on upper floors: Cleaning the bottom sash is relatively easier but washing the top half can be challenging. To clean the exteriors of such windows, you will have to either stick your head out or go outside. This makes it difficult to clean the window, especially on upper floors.
- Difficult to repair: If the upper sash of such windows break, you will need to call a professional and get the entire window replaced.
- Unsafe for kids: They can easily climb out the window by opening the bottom sash.
- Less ventilation: Single-hung windows open only at the bottom, decreasing the airflow and ventilation in the room.
What is a Double-Hung Window?
A double-hung window has two movable sashes, both of which can slide up or down. This allows proper airflow and ventilation inside the room. These windows come in aluminum, fiberglass, wood and vinyl frames. You can also select double-hung windows in various styles, colors and materials.
How Do Double-Hung Windows Work?
Double-hung windows come with two movable sashes. Both slide up or down independently. The hot air moves out of the upper sash while the cool air comes in via the bottom sash. This introduces a healthy airflow exchange in the room.
Benefits of Double-Hung Windows
The perks of double-hung windows include:
- Better ventilation: These windows allow better airflow and ventilation from both top and bottom sashes.
- Easy cleaning: These windows have moveable parts which makes cleaning from both outside and inside relatively easy.
- Safe for kids: These windows can have the top sash open for ventilation and bottom sash locked, ensuring the kids don’t climb out.
Drawbacks of Double-Hung Windows
The downsides of double-hung windows include:
- Less energy-efficient: Both the sashes of these windows can open which increases the chance of air leaks, making them less energy-efficient.
- Costs more: Both the purchase and installation of double-hung windows costs more.
- More maintenance requirements: The hardware of these windows can wear out over time, which makes it crucial for you to clean and dust them regularly.
Single-Hung vs. Double-Hung Windows: A Straightforward Comparison
Both, single and double-hung windows come with perks and downsides. Here’s a direct comparison for you to make the right choice.
Choose Right
Choosing the type of window involves considering factors such as budget, personal preference, maintenance levels, energy efficiency and kids’ safety. Depending on your priorities and family members, you can choose one between single-hung and double-hung windows. For a home with kids and need for better ventilation, a double-hung window makes the right choice. A home that needs more energy efficiency can have a single-hung window installation.
