The Jalousie Window: A Short History of Jalousies

The Jalousie Window

The word “jalousie” originated from the French word for jealousy. It refers to the notion of spying through the slats of the jalousie window. Louvered window is a common British English term used for the jalousie window, and is also commonly used in countries like Australia and New Zealand.

A jalousie window comprises of horizontal slats that can be opened at different angles to allow the free flow of sunlight and airflow.

These slats are commonly made of materials like glass, aluminum, plastic, or wood. Jalousie windows are commonly used in warmer climates.

But what is the history of this unique type of window? Here’s what you need to know:

Early use

New Englander Joseph W. Walker of Malden, Massachusetts came up with the idea of the jalousie window, and it was patented on November 26, 1901. Despite the approval of the patent, the notion of this window didn’t become popular until the middle of the 19th century.

These windows were typically found inside homes that didn’t face harsh winter climates. In colder weather, they were used on enclosed porches.

Jalousie windows were seen as a new innovation at a time in America when the country was looking to industrialize and enhance its economic potential.

The unique design of the jalousie windows combined with its ability to allow ventilation in homes encouraged people to purchase them.

From the late 1940s to the 1960s, mid-century and older homes purchased a great bulk of these windows and their sales increased significantly. However, the energy crises of the 1970s brought about their decline at the time.

Just like other windows, jalousie windows have also faced advancement in their design and efficiency, and modern jalousie windows even provide optimal security.

In modern times, these windows are seen as fashionable and are used extensively for domestic and commercial purposes.

They are considered as a valuable design element and an effective source of sunlight and natural ventilation. This consequently helps to decrease electricity costs.

Many jalousie windows today also come with airtight seals that prevent water and insects from entering homes, and help in maintaining temperature.

Why Jalousies?

The appearance of jalousie windows is comparable to that of Venetian blinds. In other regions of the globe, jalousie windows are called louver windows.

You may find them in houses in coastal parts of the United States, which have significantly warmer climates, even though they are not as prevalent in the United States.

A local business may be able to provide replacements for the jalousie windows in your house if you already have them installed.

There is a possibility that homeowners or builders who are interested in integrating this style into their design will have a harder difficulty finding this new window type.

Additional Information About Jalousie Windows

The term “jealousy” comes from the French word “jalousie,” which also means “to shield anything from view.” Jalousie windows receive their name from this French word.

These windows would have parallel slats or panes that could open as the slats on Venetian blinds do. While they were in the open position, they would provide a possible airflow.

Throughout the 1940s, these windows rose to prominence, particularly in hotter regions of the South, where the ability to let in the fresh air was seen as a desirable attribute.

Yet by the late 1960s, when residential air conditioning was becoming more common, jalousie windows were already outmoded and inefficient.

Jalousie windows are seldom used in newly constructed houses in this day and age. Yet you may be able to find them in older homes in the southern portions of the United States, as well as in greenhouses, trailers, and recreational vehicles.

How Can a Jalousie Window Be Prepared for the Winter?

Before winter, it is essential to take measures to seal any air leaks that may exist in an older house with jalousie windows.

Adding vinyl strips to the slats is one of the most effective methods to block water from leaking through. You can find a selection of vinyl slat kit options on Amazon.

The vinyl will arrive in a lengthy roll, which must then be cut to the desired dimensions. The window will have a considerably more secure seal after the installation of the vinyl stripping.

In addition, you may install thermal curtains and cover the window with a piece of plastic.

Thoughts on History

During the 1940s through the 1960s, the jalousie window was at the height of its popularity. After that, when air conditioning became widespread, it fell out of favor because of its low efficiency in terms of energy use.

Recently, many window manufacturers have completely halted production of this specific kind of window.

If you consider installing jalousie windows in your house, you may want to rethink that decision first. These windows are known for letting in outside air and providing inadequate security. Although they have a vintage feel, they are not practical for most households.
