What's the difference between a hopper and an awning window?

Hopper and awning windows are both hinged windows, but they open in opposite directions and serve different purposes in your home.

Hopper windows are hinged at the bottom and open inward from the top. When you operate the handle, the top of the window tilts into your room, creating an opening at the top while the bottom stays sealed against the frame. These windows are most commonly installed in basements, bathrooms, and other below-grade applications where you want ventilation but need to keep rain out.

Awning windows are hinged at the top and open outward from the bottom. The bottom of the window pushes out and away from your home, creating a small "awning" effect that actually helps shed rain away from the opening. This design allows you to keep awning windows open even during light rain, making them popular for year-round ventilation in Ottawa's variable climate.

In Ottawa's climate, awning windows are particularly valuable because they can provide fresh air during our frequent spring and fall rain showers. They're often installed above or below picture windows, in kitchens above sinks, or in bathrooms where privacy and ventilation are both important. Hopper windows work well in basements where you want some natural light and ventilation but need to prevent water infiltration.

From an energy efficiency standpoint, both styles can achieve excellent performance with triple-pane glass and proper weatherstripping. However, awning windows typically seal more tightly when closed because gravity helps press the sash against the weatherstripping, while hopper windows rely entirely on the locking mechanism for compression.
