Single vs Double Hung Windows

What is a Single-Hung Window?

A single-hung window, or a single-sash window, is designed with a fixed upper sash. The bottom sash can slide up and down to allow fresh air to enter your home and circulate throughout the space. Although they look identical to double-hung windows from the sidewalk, they’re very different in design and offer unique perks.

What is a Double-Hung Window?

Double-hung or double-sash windows are designed so that the top and bottom sashes can move up and down. This allows more options for ventilation, especially in homes with a second floor. When the top and bottom sashes are open, heat air rises and exits the home. This allows the cool breeze to blow in, cooling your home and keeping it smelling fresh.

Comparing Single-Hung Windows to Double-Hung Windows

So, what’s the difference between single and double-hung windows? The difference is in whether the top sash is fixed or can be opened. There are several factors to consider when determining whether you want single vs double-hung windows. The most important factors include:

  • Are they easy to clean? Double-hung windows often have tilt-latches on each sash, making it easy to swing the window inward so it can be cleaned. Many single-hung windows need this option, making cleaning difficult if they’re located on the second floor.
  • Ventilation options: Each window type allows air to flow into your home. However, double-hung windows can open the top and bottom sash, allowing better airflow and ventilation.
  • The cost: On average, single-hung windows cost less than double-hung windows. Labor and materials are more budget-friendly due to their simple design. The material you choose will also affect the price you pay. For example, vinyl double-hung windows may become more affordable than wood single-hung windows.
  • Energy efficiency: Single-hung windows are slightly more energy-efficient than double-hung windows because they have fewer parts. Your window’s frame materials will determine its energy efficiency and whether you choose add-ons like insulating foam or weatherproofing.
  • How they’re installed: Single and double-hung windows are installed with similar methods, and an experienced installation company can ensure they’re seamlessly positioned on the exterior of your home.
  • Size options: Although most single and double-hung windows are available in various sizes, some materials have limitations. Wood double-hung windows are available in larger sizes than single-sash windows made with the same frame materials.

Reviews
 We had almost all of the windows in our home (14 total) replaced. I felt like Anthony really had my best interest in mind when selecting windows, and there were no pushy sales tactics. They were very helpful and responsive along the way. The installation went smoothly and was all completed in only about 5 hours with no issues! The double lifetime warranty really puts my mind at ease too for the future. 
 Best windows and installation I have experienced. We had Champion replace some of our windows, but they have ice on the interior of the frames in the winter (I assume due to lack of proper insulation). The Bluebird windows have no icing on the interior, and are much easier to clean. We'll use Bluebird to replace the remaining windows in our house. 
 I got a lot of quotes to replace a few windows and a patio door and BlueBird was by far the best value. Quality products for a reasonable price. The install went very smooth but there were a few things on the exterior I thought could use a little touchup. They were happy to come out and fix it and the finished result is great. I will definitely use them when I replace the rest of the windows in my house.
