Amazing Ways To Soundproof Louvered Doors, Windows and More! 2020

soundproof louvered structuresLouvered doors, windows, and fences provide an aesthetic look to your building. But along with beauty, another thing that comes in is the noise. So, it leaves you with no option but to soundproof louvered structures.

To soundproof louvered doors and windows, you will have to follow either one of two ways. One way is to completely block the louvered structures with soundproofing materials. The second is to use soundproofing materials to partially block the louvered structures.

Now, that’s just general. Keep on reading this article to gain deeper insights into soundproofing your louvered doors, windows, fences, and air vents with original soundproofing materials.

Let’s begin.


soundproof louvered doors

If you want to completely soundproof louvered doors, you might find out it proves to be a bit difficult. Nonetheless, there are some measures you can take to reduce the noise coming in. For example, you can use:

  • Soundproof blankets
  • Mass loaded vinyl
  • Cover the holes with sealant.

As you know, louvered doors are both for privacy and ventilation. Its design allows air, light, and in this case, sound to pass through.

So, as you keep all these aspects in mind, let’s dive into exploring some of the best ways to soundproof louvered doors.


A soundproof blanket is made from sound-absorbing materials that can absorb and block sound from the outdoors. It is usually made of fiberglass, vinyl, and sometimes flame-proof foil.

Apart from fiberglass, vinyl, and flame-proof foil, there are some other materials used in the making of soundproof blankets, e.g., mineral wool, cotton, and mass loaded vinyl.

These blankets are consist of multiple layers of fabric, which depends on the blanket you are using. If you use a high-quality blanket, it has an NRC (Noise Reduction Coefficient), which has a high capability of absorbing noises.

Moreover, doors are one of the most noise-sensitive parts, and for louvered doors, then it’s even more. But that is not a problem because soundproofing blankets are available in different sizes and colors, so it is not hard to find one that’ll fit on your door.

It’s not really hard to install these blankets, but the main problem you will face is its heaviness.


Another method for soundproofing louvered doors is covering the holes, gaps, or cracks in it. These holes and gaps allow sound to penetrate through it, which compromises privacy.

You can completely cover the holes in a louvered door by simply adding sealant to fill them. This can reduce sound transmission by up to 100%.

After when the sealant is applied, you can also paint it so it will give you a pleasant and neat look.


Mass loaded vinyl to soundproof

Mass loaded vinyl has been used for soundproofing for decades because of its reliability and performance. Sound waves can easily penetrate a door panel, especially if it is of the hollow variety.

However, by adding a dense layer of mass loaded vinyl, you can automatically reduce the amount of noise on the other side.

Moreover, the two main features due to which MLV works are flexibility and high density, which means it has both elastic and vicious character.

If we talk about the result, in that case, high density is what makes Mass Loaded Vinyl so effective in blocking sound. Moreover, its flexibility acts as an effective sound barrier, and you get a satisfactory result.

These are the features that make MLV block sounds and vibrations more appropriately.

If you want to soundproof louvered door with MLV, then it won’t be a problem because MLV has a tiny cross-section, it’s flexible and easy to install.


Fiberglass is a form of fiber-reinforced plastic where glass fiber is the reinforced plastic.  The glass fiber is usually flattened into a sheet, randomly arranged or woven into a fabric.

Fiberglass is a lightweight type of material that is strong and less brittle. The best thing about fiberglass is that it is very flexible, and you can make various complex shapes out of it, which makes it even more useful in many cases.

Now in the case of soundproofing, the question that arises is that does fiberglass panel can be used as to soundproof louvered doors? So, a simple answer is, yes, you can.

Fiberglass is very good at absorbing the sound. However, it is much better at blocking the sound waves.

Moreover, fiberglass is considered as one of the best soundproofing materials when it comes to sound absorption.

On the other hand, the fiberglass layer is often just a few inches thick, and you can’t expect wonders from it. If you want a complete sound blocker, you would need to install a 3 feet thick layer for complete blockage.


soundproof louvered windows

To soundproof louvered windows, you need to follow certain steps as there are several ways of doing this, and by keeping these measures, you can surely get a good result.

A louvered window is one having louvered construction. It can be of wood, glass, or some other material. I always like to have a louvered window because it allows air and light to pass through.

However, it also allows sound to pass through as well, so I had no option left but soundproofing them.

Here are some measures that you can take for the soundproofing of louvered windows.


Soundproof curtains are one of the latest innovations in the soundproofing industry. They are in an affordable range, easy to purchase.

Besides, there is a straightforward and easy method of using them. You just need to hang them up.

You can simply switch your existing curtains to soundproofing curtains that are designed to dampen sound.

You just have to install these soundproof curtains on the louvered window in such a way that it covers the window as effectively as possible.

These soundproofing curtains capture and absorb a large amount of incoming sound while making the other side quieter.

All of this happens because of the special fabrics they are made up of, and one more thing you need to know is that the more the percentage of fiber, the better will be the sound-absorbing capabilities.

However, you can save your time and money because it is a cheap, quick, and effective soundproofing solution for louvered windows.


Acoustical foam for soundproofing

Acoustic foam is a lightweight polyurethane open-celled foam. If we talk about its thickness, it comes in a variety of thicknesses.

The surface of Acoustic foam is very uneven from one side. It usually ranges from egg crate shape to large pyramid or conical wedge-shaped structures.

It is commonly used for the purpose of soundproofing, and people like sound engineers and musicians use these very often.

However, you can use acoustic foam to block as well as absorb the sound waves passing through the louvered windows.

There are two types of soundproof foam, and both perform different functions, which are sound blocking and sound absorption.

You can use sound-blocking acoustic foam for a complete blockage of sound through the louvered windows. However, sound absorption foam is light, and it only absorbs the sound by reducing background sounds and reverberation.

Whether you choose the thick or light foam, installing the foam panels on louvered windows can help prevent sounds from reverberating around the room.


Weatherstrips are narrow strips, they are of different types, for example, metal, plastic, and rubber, etc. these stripes are installed around doors and windows for the heat and sound insulation.

Weatherstrips seal is particularly useful as these strips are flexible and compressible so, you can compress them between the tiny spaces in the window frame.

Besides, you can easily install the weatherstripping on the louvered windows. The installation method is quite simple; perhaps you can do it by yourself.

You just have to place the strips along each mating edge of all the panes and attach it with some adhesive or glue.


Storm windows are installed over the main glass of the windows, either from outside or inside of a house, room, or apartment.

Storm windows can be an option to soundproof louvered windows. Besides, it can help in strengthening the ability to block noises by installing storm windows in front of them.

In addition, the installation of a storm window creates air space between two windows, and an extra layer of glass provides an additional blockage of sound transmission.

However, this method of soundproofing windows can be a bit more costly than the other methods, but the result you will get is worth the price.


louvered fence

You can Soundproof a louvered fence by using several methods, like:

  • Exterior Quilted Fiberglass Absorber
  • Echo Barrier
  • Barrier Backed Composite
  • Sealants

These methods can provide you an effective result in reducing outdoor noise.

If you have a noisy neighborhood or you might be living in a place that is near to an airport, the highway, or it might be an industrial area. This could cause a noise pollution problem for you and can make your life less comfortable.

But now you don’t have to worry about it anymore, because I will tell you some fantastic methods and ideas for soundproofing your louvered fence, by using these you can reduce these annoying noises.


echo barrier to soundproof

Echo Barrier is the correct solution for all of your outside noise issues. These barriers are present in the best weight and offer an impressive noise reduction.

It is a well tested and proven noise barrier system for reducing noise. It reduces the noise by absorption of sound, reflects sound and vibration.

If you are looking for a solution at a lesser weight, then it meets all your requirements- lightweight to heavier mass solutions. Besides, it is the most durable noise barrier which you can use for your louvered fence.

Moreover, it is a reliable product and lasts longer. If we talk about its qualities, then it is incredibly durable and waterproof.

It’s a lightweight sound absorber that prevents sound from reflecting off the barrier.  It also extends product life to retain acoustic performance in any environment.


soft fiberglass panel

Barrier Backed Composite or BBC offers you both a noise barrier and a sound absorber composite in one product for outdoor applications.

BBC is reinforced with a quilted fiberglass sound absorber on one side, which offers a maximum noise reduction.

The layer of quilted fiberglass decouples the noise barrier to enhanced its acoustical performance.

You can use it outdoor and as well as indoor fences. It is available in curtain panels, rolls, custom fabrications, or die-cut pieces.

You can easily soundproof a louvered fence by applying BBC on it, and it will surely provide you a good result in making the surrounding quiet or perhaps less noisy.


You can use Exterior Grade Quilted Fiberglass Absorbers to reduce reverberant noise on permanent outdoor applications like soundproofing the fences. They are lightweight, highly absorptive, and durable panels.

It reduces the reflection of sound waves because the surface is covered with a reflective suitably UV(Ultra Violet) protected, porous, sound-absorbing product.

Moreover, its design allows both to absorb and block sound. This combination features a reduction in sound from a noise source and provides you with a relaxing environment.


You can use soundproofing sealant for sealing holes and gaps where sound may escape. It is usually present in a foam type, so after applying on the fences, it expands and covers the holes or gaps from which sound can travel.

Using a soundproofing sealant is a good and easy option for a soundproofing louvered fence. Perhaps you can do it yourself.

A sealant is a high strength, permanently flexible acoustic sealant and adhesive specially formulated for sealing. It reduces noise on the other side of a louvered and provides an excellent sound blockage.


soundproof the air vents

To the soundproof louvered air vents, we need to install different soundproofing materials like:

  • Soundproofing sealant
  • Soundproof curtains
  • Sound maze

Air vents are for the flow of air inside and outside of a room, but they can be a possible reason for traveling of sound through them.

However, if you want to soundproof louvered air vents, then here is what you should do.

For the installation of any soundproofing material, you should remember that it should not cover the vents in such a way that it disturbs the airflow.

However, the more you try to leave open space, the more noise it will be, and the more you try to close it, the quieter it will be.

Moreover, if you want to take airflow and soundproofing parallelly, then, in that case, it will only reduce the sound. But, it entirely depends on you and your preference and soundproofing goals.

If you want complete silence, then completely covering or closing the vent holes would be the best option.

Let’s say if there is less airflow in the room because there is only one window in the room, so, at this point, you have to act smartly. You have to reduce the sound and maintain airflow in the room because that is important.

Down below, I’ve given some of the easiest and effective methods for soundproofing air vents. These contain information on how to completely or partially block louvered air vents.


It is a foam sealant, so after applying it on the louvered air vents, it will expand and fill up t surface and block all of the gaps. You can also paint it after it dries up.

However, you can use this foam to fill all the gaps quickly, but before you start the work, remember to wear gloves. This whole process of soundproofing includes:

  1. Removing the vent cover.
  2. Filling up all the spaces with sealant.
  3. Let it dry.
  4. Put the cover back on the vents.


It is one of the easiest ways to soundproof louvered air vents. You just need to cover the vent with the soundproofing curtains or blanket.

These curtains work impressively because of there density. They are thicker and denser as compare to a normal curtain.

This method works quite impressively, and the best thing about this is that you just need the soundproofing curtains and simple tools to hang them.

What all you have to do is to install a curtain rod on the wall above the air vent and hang the curtains in front of it.

But you have to make sure that the curtain should be pooling on the floor. This is the only way to fully cover your air vents.


air vents maze

If you want to soundproof louvered air vents without covering or blocking the airflow, then you should consider a sound maze.

Making a sound maze inside your vent isn’t that hard as it looks. To be honest, it’s very easy, and you can make it at home even without any technical skills.

For this method, you will need:

  • Plywood
  • Woodcutter
  • Glue for wood sticking.


  1. Cut the wood in an appropriate size.
  2. Attach the wood pieces with the walls of duct in a zig-zag manner
  3. You can do this by sticking them up and down or in a side by side manner.

It works in such a way that the sound maze allows air to continue circulating freely through your air vent while being incredibly effective at the deadening sound.

Plywood dividers bounce sound waves out of the air vent. As plywoods are in a zig-zag manner so, the air inside the duct moves in a zig-zag motion as well, that makes sound waves to bounce back.

When this happens multiple times, it causes sound waves to lose momentum and scatter it more quickly.

As the air can still get through it, this will cause a sufficient airflow in the room.

I have also written a complete article on how to soundproof air vents in which I have discussed all the possible soundproofing methods in detail. I recommend you to have a look at it too.

so, soundproofing a louvered door will require you using a blanket, acoustic sealant, and MLV. For windows, you will need soundproof curtains, acoustic foams, and weather strips. And for louvered fences, you’ll need to use echo barriers, BBCs, and fiberglass absorbers. Finally, soundproofing air vents will requires the use of acoustic sealants and soundproofing curtains.

So far, we have seen different methods of soundproofing the louvered doors, windows, fences, and air vents along with their costs. Every method has its own benefits. However, I have only discussed the most effective ways to soundproof louvered structures.

Some of the methods are cost-effective while allowing you to save the time of installation too. The best example can be installing soundproof blankets on any structures.

Apart from this, you also have a choice to go for complex methods. These methods may not save you more time and money, but they are effective in soundproofing than the simpler ones. A good example can be making a sound maze for air vents. In the end, it all depends on your priorities and soundproofing needs.
