Awning Windows
An awning window is a casement turned ninety degrees. It hinges at the top and the bottom edge swings outward, so the open sash forms a small roof over the opening. That geometry means rain runs off the glass and away from the opening rather than into it.
An awning window is hinged at the top and swings outward from the bottom, forming a small canopy. The open sash sheds rain, which means you can leave it open during a storm. It seals by compression like a casement. Installed cost runs $500 to $1,000.
In a region that gets rain in every month of the year, that is a genuinely useful property. An awning is the only window style you can leave open during a thunderstorm and still not come home to a wet floor. For a bathroom that needs constant ventilation, or a bedroom where you want fresh air overnight regardless of weather, it solves a real problem.
Awnings are rarely the primary window in a room. They are usually used below a picture window, high on a wall above eye level, in basements, or in bathrooms where privacy and ventilation both matter and a full-height window does not.
Awning versus hopper versus casement
All three are hinged units. The hinge location changes everything about how they behave.
| Awning | Hopper | Casement | |
|---|---|---|---|
| Hinge location | Top | Bottom | Side |
| Opens | Outward at bottom | Inward at top | Outward at side |
| Rain protection | Excellent, sheds water | Poor, funnels water in | None when open |
| Typical use | Under picture windows, bathrooms | Basements | Main room windows |
| Sealing | Compression, very good | Compression, good | Compression, best |
| Installed cost | $500 to $1,000 | $350 to $700 | $600 to $1,200 |
Best uses in a Capital Region home
- Below a large picture window, giving you ventilation without breaking up the view.
- High on a wall above furniture or a bed, where privacy and light both matter.
- In a bathroom, where you want ventilation running even in bad weather.
- In a basement or walkout, where the opening is wide and short.
- In a stairwell or above a door, where reaching a sash would be awkward.
- On a lakefront porch, where you want air moving through in changeable weather.
The one place awnings do not work
Anywhere the open sash projects into a walkway, a deck or a path where someone could walk into it. Because an awning opens outward at the bottom edge, the projecting corner sits at whatever height the window sits at. On a window that is low on the wall beside a walkway, that is a genuine hazard. High wall placement solves it entirely, which is part of why awnings are so often used above eye level. Also confirm clearance from downspouts, exterior lighting and any siding detail the sash could bind against.

Frequently asked questions
Can you leave an awning window open in the rain?
Yes, and that is the main reason to choose one. The sash hinges at the top and projects outward at the bottom, so it forms a small canopy over the opening. Water running down the glass sheds off the bottom edge away from the house rather than running into the opening.
How much do awning windows cost?
Typically $500 to $1,000 per window installed in the Capital Region. They sit between a hopper and a casement in cost because they use similar compression hardware to a casement but are usually smaller units.
What is the difference between an awning and a hopper window?
The hinge. An awning hinges at the top and opens outward at the bottom, shedding water away. A hopper hinges at the bottom and tilts inward at the top, which funnels water inward if it rains. Hoppers are mostly used in basements where rain is not a factor and inward operation is more convenient.
Are awning windows energy efficient?
Yes. Like a casement, an awning seals by compression against a gasket on all four sides, which gives it very good air leakage performance compared to a double hung or a slider. The U-factor depends on the glass package rather than the style.
Where should awning windows be placed?
High on a wall, under a picture window, in bathrooms, or in basements and walkouts. Avoid placing them low on a wall next to a walkway or deck, because the projecting bottom corner of the open sash becomes a head or shin hazard at that height.
Can awning windows be used for egress?
Generally no. An awning does not swing fully clear of the opening the way a casement does, so the net clear opening is usually well below the 5.7 square feet code requires for an emergency escape opening. For egress, use a casement or a properly sized slider.
