Jalousie windows have been around since the early 1900s, but didn’t reach peak popularity until the 1960s. Their architectural interest made them a common addition to mid-century homes, and they were especially popular in the South because they allowed air to flow freely during hot summers.
However, the advent of air conditioning caused jalousie windows to fall out of favor, and innovations in windows mean they might longer be the best option for your home. Read on to learn what a jalousie window is and why replacement windows from Thompson Creek are a good idea.
What Is a Jalousie Window?
Jalousie windows are made up of horizontal slats that are layered in a similar way to a Venetian blind. These slats are controlled by a crank and can be opened or closed to control air flow, and when closed the slats overlap to help create a seal.
Jalousie windows are generally made with glass panes. However, you can also see them with wooden, acrylic, or even metal slats. The crank opens the slats at various angles to maximize airflow while keeping out rain.
Why Jalousie Windows Aren’t the Best Window Option
Despite their usefulness in the past, jalousie windows have many drawbacks.
They Don’t Seal Correctly
Despite the overlapping slats, jalousie windows are notorious for not creating a proper seal. They let in hot air during summer and cold air during winter, while all the good work of your HVAC system escapes. This can increase your energy bills as you struggle to keep your home’s temperature comfortable.
Government figures show that the average home can save up to $583 per year by switching to Energy Star certified windows. Replacing your jalousie windows with modern, energy-efficient models is an easy step you can take to keep your energy bills low.
Rust and Other Damage
Jalousie windows have many moving parts, from the crank that operates them to the tracks that control individual slats. Unfortunately, with more working parts there are more opportunities for things to go wrong.
As the slats in jalousie windows never close completely, water can leak through the cracks. This causes rust that can make the windows difficult to operate. Many Mid-Atlantic states have high humidity and rainfall levels, which only exacerbates the problem.
Other problems that may arise include stuck tracks, broken cranks, and missing or broken slats. It’s possible to fix some jalousie window parts, but these issues may come back after a few more years of wet or humid weather. Replacing the windows is likely to save you time and money in the long run.
Although burglaries in the United States have been decreasing since 1990, it’s still important to have a secure house. Unfortunately, jalousie windows can make break-ins easier. In traditional jalousie windows, the slats can be slipped out of the tracks silently, allowing someone to enter your home.
Fixes for this problem include adding specially made clips or gluing glass panes into the tracks, but this may cause difficulties if the glass breaks. Although some modern jalousie window manufacturers have addressed this issue, it’s generally easier to use a different style of window.
