What are the Different Types of Energy-efficient Windows?

With a variety of different types of energy-efficient windows available, how do you choose? With different operating styles, comes different levels of air leakage rates with energy-efficient windows. Energy-efficient windows come in traditional styles, including:

  • Awning
  • Casement
  • Fixed
  • Hopper
  • Single- and Double-sliding
  • Single- and Double-hung

When choosing energy-efficient windows for your home, it’s important to consider how you want them to operate. We’ll review each of the different types of windows and help you make an educated decision on which type of energy-efficient windows works best for your home.

Types of Energy-efficient Windows

Awning – These windows are hinged at the top and are designed to open outward. Awning windows open and shut easily with the turn of a handle and provide additional airflow to a room. The sash closes by pressing against the frame, which means these energy-efficient windows generally have lower air leak rates than sliding windows, for example.

Casement – Casement windows are hinged on the sides and have a crank operating system, which makes them easy to operate in hard to reach areas of your home. These types of windows have low air leakage rates similar to awning windows because they close by pressing the sash against the frame.

Fixed – Fixed pane windows don’t open. These types of windows are airtight when installed, which means they have the lowest air leakage rate, but they aren’t ideal in rooms you want window ventilation.

Hopper – These windows are the opposite of awning windows. Hopper windows are hinged at the bottom and open inward. Similar to the awning windows, hoppers are locked by the sash pressing against the frame, which makes for minimal air leakage.

Single- and Double-sliding – Both single- and double-sliding windows generally have higher air leakage rates than hinged windows. The sashes of these types of windows slide horizontally to open.

Single- and Double-hung – On a double-hung window, both sashes slide vertically. On a single-hung window, only the bottom sash slides upward. These types of windows have higher air leakage rates than hinged windows.
