Awning Windows Defined
Similar to casement windows, awning windows open outward with a user-friendly hand crank to enable ventilation. The difference with awning windows is they are hinged at the top of the frame and swing outward from the bottom, making them an excellent window choice for homeowners who desire additional airflow while protecting their home’s interior from the exterior elements.

The Milgard Ultra Series fiberglass windows are top of the line when it comes to window technology. Fiberglass is an eco-friendly window material that provides the highest energy-efficiency levels available. Fiberglass is made primarily of silica sand, an abundant natural resource. Glass is made primarily of sand. Thus the frame and glass expand and contract at roughly the same rate while remaining resistant to swelling, rotting, and warping, allowing for a longer lifespan.
Features and Benefits:
- Extremely durable with an expected lifespan of nearly 80 years.
- Strong frame material allows for large custom sizes
- Paintable frames that homeowners can update to match current home color trends
- Low expansion/contraction rate through 100-degree temperature changes means less glass and caulking failure over time
- An Energy Star package tailored to the Seattle region for optimal energy efficiency.
- Custom colors, hardware, and glass options to match any home design.

Awning Window FAQs
What is the difference between casement and awning windows?
The primary difference between awning and casement windows is the placement of their hinges and the way they open. While casement windows are hinged on the side and swing from left to right like a door, awning windows are hinged on the top and swing upward from the bottom leaving the pane to act as an awning over the window opening.
Can you install portable air conditioners in awning windows?
Yes, an awning window of the correct size can be an excellent place to install a portable air conditioner. Installing the air conditioner will require some preparation but, once done, this can be a great way to cool small to medium sized rooms while saving money on utility bills.
Do awning windows allow airflow?
Absolutely. Among all window types awning and casement windows provide the most ventilation. They are an excellent window style for optimizing natural lighting and airflow in any room during every season.
How far out do awning windows open?
Modern, hand-crank awning windows can open all the way to 90°, leaving the window pane to protrude anywhere between a few inches up to five and a half feet, depending on the window size.
