Jalousie windows, also known as louvre windows, are a distinctive style featuring multiple horizontal louvers, typically made of glass. These louvers are connected to a mechanism that allows them to open and close simultaneously. Similar to Venetian blinds, the louvers are mounted on a metal or plastic track, operated by a crank handle that allows precise adjustment of their angle to control ventilation.
Why Are Jalousie Windows So Popular?
Jalousie windows possess a unique appeal due to their distinctive design and practical ventilation benefits. They offer excellent control over airflow and can enhance the connection between your indoor and outdoor spaces.
The Functionality and Benefits of Jalousie Windows
How They Work
The slats are connected by a linkage mechanism within a track. This design ensures that when the hand crank is operated, all slats pivot open or closed simultaneously.
Key Benefit: Excellent Airflow
The primary advantage of jalousie windows is superior airflow. When fully open, they provide maximum ventilation, making them ideal for creating an effective cooling cross-breeze. This function is particularly beneficial in warm or humid climates, such as Hawaii, where the slats can be adjusted to capture the perfect amount of breeze. This makes them especially suitable for tropical climates such as Hawaii, where adjusting the louvers helps capture the perfect breeze.
The Downsides: Addressing the Limitations of Jalousie Windows
Energy Efficiency Concerns
A significant drawback of traditional jalousie windows is their inability to create a complete seal. This allows for air leakage even when closed, leading to drafts and poor energy efficiency. In hot weather, this leads to higher energy costs for air conditioning, and in the cold, it is more difficult to keep your house warm.
Security Vulnerabilities
Security is another potential vulnerability with older jalousie window designs. It’s often easy to reach inside through those open panes, and in some cases, the panes can even be removed from the outside.
Maintenance Demands
They can be difficult to maintain and prone to water leakage, which makes them a high-maintenance option.
Not Ideal for All Climates
Because they don’t seal up tightly, they’re not really the best choice for colder climates.
Aesthetic Considerations
Aesthetically, some may find the traditional design to be dated.
Fortunately, modern advancements have addressed these issues. At Grandsea, for example, we manufacture stylish and well-sealed jalousie windows. Our high-quality designs feature improved seals and construction to prevent the air leakage commonly found in older models, earning praise from many customers.
How to Repair Jalousie Windows
However, if you already have jalousie windows, a bit of routine maintenance can keep them functional.
Common Hardware Issues
Keep an eye out for things like worn or broken crank handles, damaged linkages, stuck or misaligned slats, and rusty or corroded hardware.
DIY Repair Steps
If you’re feeling “comfortable with DIY repairs, you can tackle some of these issues yourself.
- Gather Necessary Tools and Materials: Collect the required tools, such as screwdrivers and pliers, along with a wire brush, lubricant, and any necessary replacement parts.
- Remove the Window Panel (if needed): Sometimes it’s easier to work on the window if you take the whole panel out. Have a look at the manufacturer’s instructions, or if you’re not sure, it might be best to get some professional advice.
- Inspect and Identify Issues: Thoroughly inspect all components – the crank handles, the linkages, the slats, and the tracks – to see what needs fixing.
- Replace Damaged Parts: Purchase replacement parts for any components that are beyond repair. Ensure the new parts match the existing hardware for proper fit and function.
- Clean and Lubricate: Thoroughly clean the tracks, linkages, and all moving parts. Remove any dirt, debris, or rust. A silicone-based lubricant can work wonders for keeping things moving smoothly.
- Reassemble the Window: Once you’ve done the repairs, carefully put the window back together, making sure everything is secure.
Addressing Specific Issues
- Worn or Broken Crank Handles: You can usually buy replacement handles and just screw them in.
- Damaged Linkages: You’ll need to take the old ones out and put the new ones in using your pliers and screwdrivers.
- Stuck or Misaligned Slats: Regular cleaning and a bit of lubricant can often sort this out. If a slat is damaged, you might need to take the frame apart to replace it.
- Rusty or Corroded Hardware: Get your wire brush and scrub off the rust. Then, put on a rust-inhibiting primer and some paint to stop it from coming back. Don’t forget to lubricate the moving bits.
Choosing the Right Glass for Jalousie Windows
The choice of glass significantly impacts the window’s performance and appearance.
Importance of Glass Selection
It influences your windows’ appearance, energy efficiency, and privacy level.
Types of Glass
- Tempered Glass: It is heat-treated for durability and, if broken, shatters into small, less harmful pieces, making it a safe choice.
- Insulated Glass: This option is ideal for improving energy efficiency. It consists of two or more panes separated by a layer of air or gas, which enhances insulation.
- Frosted Glass: If privacy is key for you, frosted glass lets light in but stops people from seeing clearly inside.
- Tinted Glass: This is more for the look. You can get different tints to give your windows a specific style.
Factors to Consider
Think about the climate where you live, how important saving energy is to you, your privacy and security needs, and, of course, how you want your house to look.
In addition to glass, aluminum slats are another excellent option, offering durability and a sleek, modern aesthetic. At Grandsea, we have extensive experience with windows in coastal areas and can easily recommend the most suitable jalousie style for your needs.
When to Upgrade or Replace Jalousie Windows
Even well-maintained windows will eventually require replacement. If your jalousie windows are drafty, difficult to operate, or have missing or damaged slats, it may be time to consider a replacement.
New windows can provide improved energy efficiency and security, making your home fresher and more comfortable.
