Jalousie windows, also known as louvered windows, have been in use for hundreds of years. They first appeared in the 18th century in France and later gained popularity in western houses.

This window type is a classic feature of mid-century modern home windows, offering several benefits over standard windows, like bringing more fresh air and natural sunlight into the room. They also provide a functional, contemporary, and sleek look compared to traditional fixed windows.

Below, we will discuss more of these windows and count their merits and demerits.

A brief look at Jalousie Windows’ history and functionality

Jalousie windows take their name from the French word for “jealousy,” and they were originally intended to safeguard a home’s privacy. Before air conditioning became more ubiquitous in the 1970s, jalousies, which let in more light and cool breezes in the summer, were popular in the early 1900s in southern American states. They also provide a lot of sunlight and vistas because they do not have any bars or other significant impediments.

The main difference between the Jalousie windows and Venetian window blinds is that the Jalousies are fixed-picture windows with adjustable slats, whereas Venetian blinds are moveable with fixed slats.

The fitted slat of a jalousie window frame usually consists of different materials like wood, aluminum, acrylic, vinyl, glass, etc.

While leakage is one of the substantial disadvantages of louvered windows, some manufacturers offer inside or outside-mounted screens that help prevent leakage.

The Advantages and Disadvantages of Jalousie Glass

The advantages of jalousie windows

Ventilation

One of the substantial benefits of jalousie windows is that they promote ventilation and prevent rain from entering the room. Older mid-century homes in warmer areas with sunrooms or enclosed porches are perfect for these types of windows.

Sunlight

They allow the right amount of light into the room while simultaneously blocking off direct sunlight and providing unrestricted vistas.

The disadvantages of Jalousie Windows

Leakage

Unfortunately, the old ones do not have an airtight seal, which makes them prone to leaking water or cold air into the room even when the window is closed. Due to that, modern jalousie windows are slim and equipped with window screens.

Safety concerns

They are simple options for burglars because they can be opened easily without shattering window glass.

Energy-efficient

Many jalousie windows do not have an airtight seal, so they easily allow air conditioning to escape, which makes homeowners think of additional window insulation, especially during the winter.

Rust

Jalousie window glass slats can break over time, and their metal clips and crank handles are prone to corrosion and rust in rainy and windy climates. Moreover, repairing each part and cleaning the slats can be challenging and costly.

Types of jalousie windows

It is easy to change the function, style, and appearance of jalousie windows only by altering the slats. The slats are available in different colors and textures and contain various materials like acrylic, aluminum, plastic, wood, glass, vinyl, etc. Solid slats offer more privacy, while glass slats provide frosted and tined designs.

When the slats are changed, the windows have a completely new appearance, whether used as kitchen windows in a beach home or enclosed porches.

The slat easily unhooks and pulls out of the frame, making it simple to change with different materials. The only requirement is that the width, length, and height of the new slat should match the frame’s size.

Their hand crank function gives leverage and makes it simpler for those who may not have a lot of strength to open the window.

In addition to being manually operated, you can open and close them remotely.

The alternative to jalousie windows

Casement windows

If you are seeking Jalousie window substitutes, casement windows are a more contemporary choice that provides comparable functionality. Casement windows, unlike jalousies, are not fixed and open outward using a hand crank, making them very energy-efficient and providing a tight seal.

Sliding windows

You can get as much airflow as you need with sliding windows since they have a fixed sash and one that opens horizontally. This window style is typically less expensive than casement windows, but it may cost more to maintain. It also has a tight seal and allows unhindered views.

Awning windows

Awning windows are a fantastic additional solution for maximizing ventilation. Unlike casement windows, their hinges are located on the top of the frame rather than the sides. The ability to put awning windows at various heights on the wall makes them more adaptable, customizable, and versatile, offering you more alternatives. This feature is perhaps one of their best advantages.

Jalousie Windows Security Tips

A slat holder is a feature of more recent jalousies that keeps the slats from being removed when they are closed. There are various ways to increase the security of older jalousie windows, though.

  • Many hardware stores sell S-rings or S-hooks to stop glass panels from being removed.
  • Louver lock kits are the best option to keep the glass slats on Louver windows in place.
  • The security clips for jalousies have a high-tension spring. There are different forms of window locks that are clipped beneath the louver windows to prevent the slat from being removed.
  • The glass slats are attached to the metal frame using silicone sealant or epoxy adhesive. This is the other safety recommendation.

Are Jalousie Windows a Good Investment?

Jalousie windows are no longer popular in cold climates, however, some manufacturers are modernizing them to fit more contemporary homes.

Since they have been in use for so long, jalousie windows have essentially served as an early form of air conditioning.

Modern windows like casement, sliding, and awning models provide better ventilation, are more energy efficient, and have less leakage for around the same price as jalousie glass, which makes them better solutions if you want to maximize ventilation and airflow.
