What Is The Difference Between Hopper and Awning Windows?

It is important to know the difference between awning and hopper windows when purchasing new windows for the home. While the difference between these two windows is not major, knowing their separate benefits is helpful. In this article, we will go over the differences between both of these windows and the purposes they serve.

Hopper Windows

Hopper windows are usually placed in a basement, attic or other hard to reach areas that need ventilation. The way that hopper window opens in to the home and pivots on the bottom two corners of the window attached to the door frame. While it varies which 2 corners the window pivots on, it is more common to see the bottom two corners staying connected to the frame while the window opens in from the top. There is sometimes a chain to suspend the window, because in most cases it only opens 45 degrees. It is more common to have metal attached to the bottom part of the window to hold it in place at 45 degrees (see picture below). Hopper windows also use weather stripping to seal the window off from the elements, so naturally it is not as energy efficient as it's awning counter part. Overall, hopper windows are great for the basement or the attic, where there is not a huge emphasis on appearance.

Awning Windows

Awning windows are similar to hopper windows in the sense that they both only open on 2 of the 4 corners of the window. However, contrary to hopper windows, awning windows open from the bottom leaving the top 2 corners secured to the window frame. Awning windows are more decorative and compliment the external appearance of the house, compared to hopper windows which are usually reserved for attics and basements. Awning windows are the ideal choice for larger areas that require ventilation year round. This means they work especially well in the kitchen, an area that needs frequent ventilation. There is also a bit of hardware that goes along with awning windows in the way that they open. They use a crank to slowly open the window to varying degrees. This allows the user to regulate how much airflow they want coming in and out of the home. Additionally, awning windows use compression seal to insulate the home better. This provides stronger insulating properties than hopper windows, although we do recommend using windows that are insulated with krypton and utilize Heat Mirror Technology for the best insulation.
