6 Ways To Soundproof Jalousie Windows That Actually Work

Most people wonder how to soundproof a Jalousie window. In this article, we will be discussing useful soundproofing methods to help you get the best from them.

As far as windows go, Jalousie windows are one of the most efficient and beautiful of them all. Jalousie windows are made of glass, or wood and are widely used in homes, offices and so on.

Jalousie windows are also called Louver windows and are appreciated for their unique benefits.

Aside from beauty, here are what makes a Jalousie window so unique;

  1. They maximize airflow; while other windows might seem to regulate how much air you can get, Louver windows are generous with a strategic design to optimize airflow.
  2. They are easy to use with flexible control for comfort. You can leave the panels wide apart on hot days and slightly open on cold days.

I enjoy these windows because of these special qualities, but the problem with them is noise.

With Jalousie windows you encounter various forms of sound from different sources. There’s noise coming in from outside your home or room and merely closing your majestic windows does very little. Waves transmit noise through the air or home structures.

If you have noisy neighbors, you can be sure all that sound will filter in along with the cool breeze. Also, there is the issue of the window itself which makes creaking, scraping and loud noises as you close, or open them.

In my experience with Jalousie windows, soundproofing them is hardly straightforward. Louver is different in structure from other windows, so the steps to take are entirely different also.

Jalousie windows permit maximum airflow, and the air is an efficient transmitter of sound. Blocking out sound might mean sacrificing this breeze, but not necessarily if you do it right.

how to soundproof jalousie windows

1. Seal with Weather Strips/Insulating Strips

Weather strips or any rubber seal are particularly useful because you can compress them between the tiny spaces in the window frame.

For Louver windows, the strips have to be placed along each mating edge of each pane. The process is simple, and you can do it yourself. The materials required include;

  • Screwdriver
  • Gloves
  • Insulating strips
  • Cutter

Step One

First, remove the glass panes from the window structure (this is assuming your jalousie window is made of glass, the same method applies to any other material). Wear gloves and use a screwdriver for this process.

Step 2

Strips come in different shapes, but they are all malleable. Weather strips usually come with an adhesive side. Peel off the adhesive covering and begin use of the strip.

Step 3

Starting from the first edge of the windowpane, fill the strip into the spaces between; cut the strips with a cutter when you reach the end of a pane.

Use a screwdriver tip or any flat but rigid object to push the strip tightly in between the panes. Do this for all the panes. Bear in mind that using the strips will make the panels less flexible than usual, you will feel it as you open and close the windows.

Insulating the window with these strips will not only reduce noise but makes it more energy efficient.

2. Install Storm Windows

Storm windows are a popular soundproofing option for windows in general. A storm window is a window installed either outside or inside of the main windows of a house.

They function as added insulation to the home and also soundproofing. Installing a storm window is relatively easy, but you can call a professional to guarantee a thorough installation.

The materials and tools needed for this process include:-

  • Screwdriver attachment
  • Combination storm window
  • Caulk and caulk drill
  • Pencil
  • Hammer
  • Utility knife
  • Measuring tape
  • Level
  • Dust mask

Step 1

Use the measuring tape to determine three widths of the window. These are the top, bottom and middle width.

They may not be the same measurements, but the difference should not be more than an inch or two. Take down the measurements. Also, measure the height of the window from the outside.

Step 2

Use the lowest measurement to order the storm window.

Step 3

Scrape the loose paint from the window, use the dust mask during this process.

Step 4

Drill weep holes in the window sill to enable water drain out from the bottom of the windows.

Step 5

Apply caulk along the edges of the storm windows excluding the bottom part.

Step 6

Now, place the storm window and screw it into the window frame. Use the hammer and utility knife to install the expander tightly into the window sill.

After the process ensure the storm window opens and closes just fine.

3. Soundproof Curtains

Soundproof curtains are made from layers of thick materials and are designed to reduce or strategically deaden sound.

Soundproof curtains come in different forms and thickness; however, the principle behind this curtains is –the thicker, the better.

Soundproof curtains are a good investment especially for jalousie windows because they reduce sound and you get to keep some of the luxurious air.

They are also aesthetic. When purchasing a soundproof curtain here are a few tips to help you make the best choice;

  • Weight
  • Curtain rods
  • Material from which the curtain is made
  • Ease of installation
  • Size including width and height
  • Recommendation

Installing a soundproof curtain is quite similar to installing your regular curtain the unique difference is the new weight of the curtain and high up rods. You can do the installation with the help of a friend, or you can call on a professional.

Always ensure that the soundproofing curtains cover your windows from top to bottom, and from side to side.

4. Acoustical Caulk

Acoustical caulk is quite standard for soundproofing windows. The use of acoustical caulk is based on the principle that sounds filter in through holes and cracks in our homes. Purchase a suitable sealant and make sure to read the manufacturer’s instructions before using the product.

Take necessary precautions to protect your eyes, hands and mouth when applying the sealant.

Use acoustical caulk around the window frame, in any cracks or holes.   Allow drying for about 48 hours.

Acoustical caulk is a useful and practical option, but if it doesn’t work for you by itself, you can reinforce your soundproofing with a soundproof curtain, or insulating blinds and window shutters.

5. Acoustic Jalousie Windows

The option of acoustic windows is for those who haven’t installed the entire window yet or who would like to replace with a new one.

Jalousie windows are quite historical and have been more popular in the past than now.

Nevertheless, you can still benefit from the latest designs which have taken all the past problem of Louver windows into consideration.

Acoustic jalousie window will save you the entire stress of trying to soundproof your windows. Part of the benefits of acoustic jalousie windows now available in most countries include;

  • Improved soundproofing– the decibel levels vary depending on the company and your selection. But on an average level, you can get up to 32dB of sound reduction.
  • Improved energy saving capabilities
  • Complete protection from the elements

6. Installing Blinds and Soundproof Shutters

Other methods to soundproof your windows include insulating blinds and shutters


Usually, any type of blind will work to absorb sound but only at a minimal level. You can purchase blinds with double cells or some thickness. Blinds, however, operate by absorbing or redirecting air so that they will reduce airflow along with the sound. They are useful but can only do so much.


Shutters are a better option because they close away sound almost entirely. They are also at an advantage because of the availability of soundproof shutters for a more specific effect.

Supporting shutters by necessary caulking can be all you need to enjoy peace with your jalousie windows.

Final Thoughts

Before anyone can undergo a soundproofing project always keep in mind some specific details, such as:-

The level or source of noise you want to keep out

This will determine the option you choose. Deafening noises will require better options like the storm window and thick soundproof curtains; while smaller sounds can be shut out by caulking or other measures.

The cost

I always believe that the extent of your soundproofing depends on your budget. Choose from the options you can afford, and undoubtedly there will be something that works for you.

Would you require professional help?

It is always safer to call a professional for your projects. DIYs are fun and work just fine but if you don’t have the time or necessary knowledge then call for help.


Thanks to new designs that come up daily, soundproofing homes do not hamper your decorative desires. Most soundproofing materials are designed to suit your preferred style and enhance beauty.

Jalousie windows are one of my personal favorites because of their natural efficiency. If you want to get the best from your windows without sacrificing too much comfort, then you have to choose wisely from your soundproofing options.

Bear in mind that all methods work, but it depends on the noise you hope to reduce and your available budget. Comfort is priceless and so is peace of mind.
