Are Double-Hung Windows More Efficient Than Awning Windows?

Hung windows are one of the most common window styles in American homes but they're not your only option. There are several other operating styles available that also offer greater energy savings than hung windows. In this post we're comparing double-hung windows and awning windows. We'll detail how these windows operate and how that affects their energy performance. Keep reading to learn more.

Double-Hung Windows vs. Awning Windows

Double-hung windows have two operational sashes that allow the window to slide up or down. They are a popular choice in home styles↗, such as Cape Cod, Victorian, and Colonial style houses. Double-hung windows have a classic look and they offer more ventilation than single hung windows. In fact, double-hung windows are great for homes where the homeowner wants more control over ventilation. This style typically also has tilt-sashes which make cleaning the windows easier especially on homes with multiple levels.

Awning windows are designed to increase airflow and because of the way they're designed you can leave them open when it rains without being concerned about water intrusion (unless it's super windy, then you'll definitely want to close them!). This window style is hinged along the top of the frame and opens outward from the bottom with a rotating hand crank. Their ability to open outward creates a natural funnel that draws airflow into the home. Awning windows pair well with casement or picture Windows.

Are Double-Hung Windows More Energy Efficient Than Awning Windows?

The energy efficiency of any window style can be improved with insulated glass units and premium frame materials. While fewer movable parts in a window allow for less air leakage, this is only one aspect to consider when you desire optimum weather sealing.  Awning windows have tighter seals and fewer moving parts than a double-hung window. If they're made from the same material and with the same pane amounts, Awning windows would probably be more energy efficient. 

Owners of double-hung windows should not fret. This window choice can still be as energy-efficient as the awning, casement, picture, or single-hung window options with insulating, multiple glass panes, and durable framing materials. So while there is no definite winner in the "who saves more energy?" competition, it's good to know energy efficiency can be achieved with whatever style you choose. 

Benefits of Energy Efficient Windows

  • Controlling condensation that can be damaging to window frames and seals
