Hopper windows work in a similar fashion to a casement window, in that they are both hinged. The difference is that hopper windows open inward and down from the top. Whereas a casement window is hinged on the side and opens outward. To open a hopper window, you pull the top of the window towards you. In the open position, the window resembles the shape of a chute or hopper, hence the name.
The first hopper windows were called “transom hopper windows” and as the name implies, they were commonly used in transom locations in older homes. They were often found in Victorian homes and gained immense popularity in the 19th century. The windows continue to be popular today, particularly when space constraints favor their use.
Popular Uses for Hopper Windows
Walkways: In high traffic areas such as walkways, driveways, and patios, hopper windows are a great choice. Unlike casement window which open outward and create an obstruction, hopper windows open inward and will not block the path.
Basements: Quite often the vertical space available for basement windows is limited. This is the perfect place for a low-profile hopper window, which will also provide adequate ventilation.
Bathrooms: Speaking of ventilation, hopper windows are commonly installed in bathrooms above tubs or showers where space is limited. In this application, the windows accomplish two functions, improved ventilation and allowing additional natural light to enter the space.
Kitchens: If you look close at this kitchen makeover you will notice the hopper window over the sink. This unique design added some flair to the interior design on this project, while at the same time improving the ventilation in the kitchen.
Benefits of Installing Hopper Windows
Security: A hopper window can be very difficult to open from the outside. This can be a deterrent for would-be burglars. Additionally, in most cases the windows are very small, making it difficult if not impossible for intruders to enter through the open window.
Insulation Value: Hinged windows such as casement windows, awning windows, and hopper windows generally have a superior seal design. The crank action and latches of these windows ensure that they close tight against the frame for an air-tight seal. Couple this with Low-E glass to reduce your energy cost.
Humidity Control: Hopper windows provide excellent ventilation for steamy bathrooms and musty basements. Providing adequate ventilation in these areas will reduce the possibility of mold forming in your home.
Easy Installation: Hopper windows are fairly simple in design compared to the complexity of double hung windows. With fewer moving parts, they are easy to install and maintain. They are also very economical to purchase.
