Single-Hung vs. Double-Hung Windows: Which Should You Choose?

Single-Hung vs. Double-Hung Windows: Which Should You Choose?

October 11, 2019

Single- and double-hung windows are probably the most iconic window styles. While there are similarities between these two options, they also have significant differences.

Read on to discover how these two window replacement options are different and which one is better for your home. 

Single-Hung Windows

Single-hung windows have one stationary sash on the top and a moveable sash on the bottom. The bottom sash slightly obstructs the upper sash when the window is open. These windows usually can’t tilt in and out. They are a great option if you’re aiming for a more authentic look or if you have a historic home. These windows may be preferred for modern homes for their cost-effectiveness.  

Double-Hung Windows

Double-hung windows are the most popular window installation and replacement option in the U.S. Both sashes of a double-hung window can open and tilt, making it easier to access both panels when cleaning. Double-hung windows doesn’t only just increase ventilation, but they also make cleaning and maintenance simpler and safer. 

Single-Hung vs. Double-Hung

Cost and Materials

Single-hung windows cost less than double-hung windows because they contain fewer moveable parts. Double-hung windows require the highest-quality frame structure to prevent the seal of the top sash from breaking over time due to gravity’s pull. However, with a high-quality frame, you can ensure your windows last longer and provide more protection. 

Keep in mind that whatever type of window you choose, it needs to be properly installed to function correctly. Make the most of your investment by choosing Renewal by Andersen® of Eastern NY for your window replacement. We offer energy saving windows that can help in reducing your monthly utility bills.  


Only the bottom sash of a single-hung window opens, which means this window style can’t provide as much ventilation as a double-hung window. Since you can open both the top and bottom sash of double-hung windows at the same time, they offer more ventilation. The warm air escapes through the top and the cool air enters through the bottom, circulating fresh air into your home and letting stagnant indoor air escape. These windows are beneficial for rooms with high-moisture levels like bathrooms and kitchens. 

Energy Efficiency

Whether you’re looking for single-hung, double-hung or casement windows, you should pay attention to the U-factor of each product. Single-hung windows are more airtight than double-hung windows in general. However, limited ventilation means your heating and cooling system may have to work harder, depending on your climate. This can result in higher energy costs. 

Styles and Variations

Single-hung windows can provide a more authentic look in historic homes. Like picture windows, their immovable sash can be made in any size or shape. They can hold multiple panes of glass per sash. 

Double-hung windows are available in a wider range of materials, trims and colors. However, their moveable sashes can’t be customized in different sizes or shapes. They can hold multiple panes of glass per sash like single-hung windows. 

At Renewal by Andersen, we offer custom windows of all types. Our custom-built, double-hung windows are built with Fibrex® material frames. Fibrex is an innovative composite material that combines the durability of vinyl with the attractiveness of wood. Our windows come in 37 different interior and exterior color combinations, making it easy to find an option that complements your home’s style.  


The moveable bottom sash of single-hung windows is dangerous for pets and small children, especially when it comes to windows on the upper floors of your home. Double-hung windows avoid this problem by incorporating separate locks for each sash. They also feature a stronger, heavier frame, enhancing safety. You can have the top sash open for ventilation and keep the bottom closed to eliminate the risk of danger for small children and pets. 

Upkeep & Cleaning

Since single-hung windows only open from the bottom and usually have a tilt-in capacity, they need to be cleaned from outside. For your safety, we recommend hiring a window cleaning professional to wash windows on the upper floors of your house.

The operability of double-hung windows makes them very easy to clean. They raise and lower to let you access hard-to-reach areas. Because they also tilt inward, they are the simplest window type to clean from your interior. These features make cleaning upper-level windows easy and safe.

Which Should You Choose for Your Home?

Choose double-hung windows if you’d like to be able to operate both upper and lower sashes. They are also the best option if you prefer having removable sashes. As mentioned, double-hung windows are ideal for kitchen and bathrooms due to increased moisture levels and odors in those areas. 

Double-hung windows provide a classic appearance that can complement any home style. When you choose Renewal by Andersen for your double-hung window replacement, you’ll receive our unique five-star installation service, ensuring your replacement windows perform as expected.
