Comparing Single and Double Hung Windows
Single- and double-hung windows may look similar, but there are significant differences in functionality to consider. The right choice depends on your priorities. Windows on Washington can help you understand your options and choose the right replacement windows for your project.
What is a Single Hung window?
Also known as a single-sash window, a single-hung window has an operable lower sash and an upper sash that remains stationary.
Ventilation
Because only the lower sash is operational, a single-hung window offers fewer ventilation options, even though generally both single- and double-hung windows offer the same total amount of ventilation.
Energy Efficient
The material used to manufacture the replacement window has a greater effect on energy-efficiency than whether the window has a single- or double-hung configuration. However, single-hung windows may allow less air infiltration rates, meaning they can keep your home cooler in summer and warmer in winter.
Cost
Single-hung windows tend to be a cost-saving solution, especially in new construction projects, because they are easily mass-produced and tend to be of lower quality than their double-hung counterparts. Single-hung windows are rarely used in residential remodels.
Design and Best Use
Single-hung windows are best suited for mass-market, new construction projects at scale, such as apartment buildings and townhome communities.
What is a Double Hung window?
Also known as a double sash window, is a window that has both an operable lower and upper sash to allow for greater ventilation.
Ventilation
Double hung windows offer the flexibility of ventilating from both the top and bottom sashes, allowing for better maximum air movement and circulation.
Energy Efficient
Both single and double hung windows are designed with energy efficiency in mind. The material used to manufacture the window (fiberglass, vinyl, composite, or wood), has a greater influence on energy efficiency than the double hung vs. single hung configuration.
Cost
The cost of a double hung window is typically higher than that of a single hung window. While slightly higher in cost, the benefits of a double hung window in a residential remodel project tend to far outweigh any cost saving benefit.
Design and Best Use
Double hung windows are a popular choice for their classic design and timeless appeal, making them suitable for various architectural styles. Double hung windows also offer easier cleaning, as both sashes can tilt inward to give access to both interior and exterior surfaces of glass.
