Hopper Window is the term for a window we have all seen many times, but many of us never knew its name. Typically utilized in basement applications, they are like a casement window that is hinged at the bottom and tilts open at the top, instead of the side. The only difference in how the hopper window operates is that it opens in, instead of out. The screen on the hopper window is on the outside.

A similar style of window is the awning window, which is hinged at the top and tilts open at the bottom, somewhat like a fabric awning. Because the awning window opens outward, the screen is on the inside.

Windows with compression seals allow about half as much air leakage as double-hung and horizontal sliding windows with sliding seals. In other words, hinged windows generally have lower air leakage rates than sliding windows because the sash presses against the frame when closed. Like awning and casement windows, hopper windows are energy efficient. The compression seal of these windows keeps heat/air conditioning in, and the elements out.

The main benefit of hopper windows is that there are no sharp corners hanging down to whack you in the head, and it helps prevent leaves, dust, and trash that might be blown along the ground from blowing right into your basement.

Another benefit of hoppers, like casement windows, the entire window area can be opened, while sliders are limited to less than half of the window area.

You may also have seen hopper or awning windows in old movies or in older buildings that are built over a door. The term for this type of window application is a transom window. Transom windows were typically utilized in hotel and office rooms before air conditioning became commonplace.

If windows serve as your connection to the outside world, then it’s important to make sure yours are working for you. Hopper style windows are great for bathrooms, basements, and any other room that could benefit from better air circulation and tighter energy efficiency. Here’s how to know if they’re right for your home.

Costs

The cost of hopper windows depends entirely on the size of window and the price of labor. Estimates range from $60 for a small basement window to $150 for an average-sized window.

Pros

The angle of the window prevents dirt, leaves and other debris from blowing into the house.

Hopper windows are the best choice when it comes to providing optimal ventilation in small areas, like bathrooms.

Hopper windows are super energy efficient. When closed, they offer a tight seal that prevents air from entering or exiting.

Cons

If not secured shut during thunderstorms, rain is easily leaked inside the house.

Because windows angle outward, it’s hard to install blinds or window coverings, making privacy an issue.

Hopper windows are usually installed close to the ground. With easy-to-reach fasteners, they might prove a security risk.

Durability

The durability of the hopper window depends primarily on the manufacturer. While some homeowners are concerned about the flimsiness of the hardware used, some manufacturers like Atrium construct their windows with stainless steel hardware. Do your research before settling on one brand.

Maintenance

As with any other window, hopper windows should be routinely cleaned for best results. Using a household glass cleaner or solution of vinegar and water, wipe your windows clean with a soft cloth. Also make sure to occasionally clean the screens with water and mild soap.

Common Questions and Answers

What is the difference between awning and hopper windows?

Hopper windows are basically awning windows that open from the top and are placed lower on the wall. Awning windows also tend to direct rainwater away from the home, while hopper windows let rainwater in.

History

Originally called transom hopper windows, this window style was popular in Victorian homes during the 19th century. The angle of the window helped block the dust and grit that was a common byproduct of unpaved roads.
