How To Remove Jalousie Window Panes? Safely!

Jalousie windows are an economical and energy-efficient way to let in air and light. They consist of a series of overlapping glass slats that tilt open or close through the use of a crank mechanism on the side. Removing jalousie window panes is not complicated, but will require some patience and effort. Here’s how you can do it safely and easily:


Before starting the removal process, make sure you have all of the necessary tools at hand: safety glasses, gloves, flathead screwdriver, utility knife, pliers, or channel lock pliers. Also, ensure that you have enough space to work comfortably without hindering your movement.

Step 1: Removing the Crank Mechanism

Remove the crank mechanism from the jalousie window by loosening the screws on either side of it with a flathead screwdriver.

Be gentle, as these screws may be old or brittle and can easily break if you apply too much force. Once all of the screws have been taken out, slide off the crank handle and set aside.

Step 2: Opening/Removing Slats

Once the crank mechanism has been removed, open up each slat one at a time by using a utility knife or channel lock pliers to carefully pry them open. This will allow you to remove each pane individually without damaging the slats or glass.

Step 3: Removing the Glass Panes

Once you have opened up all of the slats, carefully remove each glass pane. Depending on how old your jalousie window is, the panes may be held in with glazing putty or adhesive. If this is the case, use a putty knife to carefully pry them out.

Be sure to work slowly and take care not to scratch or crack any of the glass panes during this process.

Step 4: Cleaning Up

Once all of the glass panes have been removed from your jalousie window, it’s time to tidy up! Use a vacuum cleaner or shop vac to clean up any dust, debris, or broken glass that may have accumulated during this process. If there was glazing putty on your window panes, you’ll want to remove it from the slats as well.

Step 5: Replacing the Window Pane

Finally, when all of the dirt and debris have been cleared away and the window is ready for a new pane of glass, use a piece of double-strength glass that’s cut to fit your jalousie window.

Place the new pane in its correct position and secure it with glazing putty. Once again, be sure to work slowly and carefully in order to avoid scratching or cracking the pane of glass.

Step 6: Cleaning and Finishing

After all of the new glass has been secured in its proper place, use a damp cloth to wipe away any excess glazing putty or debris that may have accumulated during this process. Once everything is clean again, you can open and close your window with ease!

When it comes to jalousie windows, regular maintenance, and upkeep are key to keeping them looking great for years to come. After replacing one of your panes of glass, be sure to inspect the other slats on a periodic basis just in case they need attention as well.

With some patience and dedication, removing and replacing jalousie window panes shouldn’t be too difficult. Good luck!

Safety Measures

When removing jalousie window panes, it is important to take safety measures into consideration. Depending on the height of the window, you may need a ladder or some other type of support in order to reach it.

Make sure to take all necessary precautions when using heavy tools and sharp objects. Additionally, wear protective gloves and glasses in case any glass shards come loose during this process.

Regularly inspect your Jalousie windows for signs of wear and tear, including cracks, chips, or other signs of damage. Damaged panes should be replaced as soon as possible to ensure that the window functions properly.

A: Jalousie windows are typically opened and closed by using a crank-like handle that is located at the center of the window frame.
