Awning Vs Hopper Window

Awning windows hinge at the top and push outward to open.

Awning vs hopper window.

A big advantage of awning windows is that they can stay open in any weather and keep the rain out of the house while letting fresh air in. Perhaps the most salient functional difference between these two types of replacement windows is that the sashes on awning windows open outward while the sashes on hopper windows open inward. Depending on the company or the brand of the windows the sash in a hopper may open at the bottom or the top. Many hopper windows have a small design and are seen in basements and bathrooms whereas awning windows are larger and often found in bedrooms and kitchens.

In awnings the sash moves outward away from the house. When the window is open the glass pane creates a little roof over the opening. They operate on a crank or there might be another mechanism used to keep the window open securely otherwise the sash might slam shut. On awning windows these hinges are along the top whereas on hopper windows they are along the bottom.

Instead of opening inward like hopper windows awning windows open outward so the glass pane creates an awning over the window opening. While the top two corners of the sash are still the ones connected to the frame and the window still opens from the bottom hopper windows open inward. However an open hopper window would allow the rain to slide down the glass and spill into a structure. Awning windows opens outward from the bottom the hopper window on the other hand does the opposite.

A hopper window is essentially the opposite of an awning window and when you flip the design you get a whole new set of perks. In hopper windows the sash moves inward. They are like a casement window but with the hinge mounted on top. Sure you ve probably seen plenty of hopper windows in your day but a hundred years ago hopper windows were new on the market an invention for the modern era.

Another difference between these two types of windows is the awning window could be open during a rainstorm and let very little rain enter the structure.
