Jalousie Window Replacement

Jalousie windows are made of slats of glass that fold open and closed similar to a shutter, allowing you to maximize ventilation. Like an awning window, their slats help repel rain and keep the weather out, allowing you to bring in cool air even during rainy days without soaking the floors. A popular mid-century modern choice, some homeowners are opting for the window style in their homes for their ventilation and aesthetic. 

Here’s what you need to know.

What Are Jalousie Windows?

Jalousie Windows are comprised of several slats of glass or other materials, which can be opened and closed with the turn of a crank. They are known for their signature appearance and ventilation. 

How Do Jalousie Windows Work?

Jalousie windows’ horizontal slats are layered on top of one another, similar to shingles or siding. The top of the bottom slat is covered by the bottom of the slat above it and the cycle continues all the way up. A crank opens the slats. As the crank is turned, the bottom of the hinged slats tips up and out creating an opening. Most can become fully horizontal creating a nearly unobstructed view of the outdoors.

Most of these window types make use of glass panels, especially the modern options, but some use aluminum panes, or other solid materials to create a more durable window. These solid panes can still both ventilate and create a view because of how they open.

Consider This Window Type If…

Jalousie windows offer homeowners three main features. If they are important to you, put this window type high on your list:

1. Ventilation capabilities. Homeowners can easily open and close the window’s slats to control a home’s airflow. Even when these windows are open, their slats are able to block the sun and rain, making them a popular choice during mild storms. These cranks are manually powered, meaning if a home loses power, you can still open and close the windows.
2. Easy to repair. If a slat breaks, it can easily be replaced without having to remove and replace the entire window. 
3. Unique design. With multiple materials to choose from, this appealing window stands out from more traditional options.

Types of Jalousie Windows

Jalousie windows come in several types of materials in addition to glass. They include: 

Glass: Glass jalousie windows are the most common style. They offer a clear, unobstructed view outside and are easy to clean with just soap and water. 

Aluminum: Lauded for being both lightweight and durable, aluminum slats on a jalousie window are also easy to maintain and resistant to weathering over time. 

Wood: Wooden slats can easily be painted or stained to match a home’s decor. 

Window Screens

Like any other window style, a jalousie window can easily be outfitted with a screen.  Window screens are commonly used to help keep unwanted critters, dust and debris outside of a home when a window is open.

Since the slats of these window type do not create an airtight seal when closed, screens are often recommended.

Before Buying: Factors to Consider

Before making a final decision, there are several factors worth considering. While they offer a beautiful design element and lots of air flow, common criticisms of jalousie windows include their availability and that they are not airtight when closed. 

Let’s take a look at some of the pros and cons of jalousie windows.

First off, it’s important to think about which room in your home the window may be going in. Jalousie windows are best suited for rooms that need good ventilation, like kitchens and bathrooms. If you are considering putting them in a bedroom, it’s important to think about outdoor noise since these windows are not particularly soundproof. 

Jalousie windows’ horizontal panels are ideal for ventilation, but not for home security. If you have window locks, cameras, or an alarm system to help mitigate risks, you may feel more secure choosing this window type.

Because of their ventilation prioritization, jalousie windows are not the best for energy efficiency since they do not create as tight of a seal as more traditional windows. This drawback can be compensated for with the selection of energy-efficient installation materials and proper insulation. 

Unlike a standard window, this window style calls for multiple moving panels. This can play a role in the window’s mechanical functionality and a need for additional maintenance over time. 

They are also less common than other window styles, making them trickier to source and more expensive to install. 

The Bottom Line

Since the windows are not perfectly sealed when they are closed, these are best suited to areas with a mild climate year-round. Consider your region’s weather when deciding if a jalousie window is the right fit. Your climate can also help tell you what materials to use. For instance, in coastal areas, aluminum may be best since it resists saltwater corrosion. 

Jalousie windows require regular cleaning and maintenance to keep them in working order. But typically, they won’t have as long of a lifespan as more traditional window options before needing to be repaired or replaced.
