  • Materials: Green glue, MDF or OSB, mass loaded vinyl, handle, weatherstripping, decorating items.

Now the game begins!. 

1. Measuring The Dimensions 

What is the size of your window and how much depth do you want? Before cutting the right size of soundproof plug or insert.

This is important to have the measurements. This will give you the right path and the exact amount of material to be eliminated.

So starting from the top you need to measure the length, width, and depth of the complete window. Because the window frame is a little bit smaller than the cavity.

But make sure to check the space. That should be left between the soundproof plug and window frame. 

This will prevent the vacuum that may ruin your work. For this work, you can use a measuring tape and note it down somewhere safe.

This will help you to complete the next step. Because the wrong size will not work at all. 


2. Cut The Materials

This is the most difficult part of this project. Because if you do anything wrong while cutting. Then you need to have another board.

But don’t worry this will not take more time and if you have already done the cutting job. Then you can easily do it. 

So you only need a piece of MDF or whatever plywood you have. Then carefully put it in a clean place and use a table or circular saw whatever you have.

But this will make the work more quickly. But I don’t want to do all these things by myself. 

Then you can buy the exact size of plywood from any local hardware shop. But keep in your mind that the soundproof window plug should be snug as much as possible.

So that it can easily block unwanted things from outside.


3. Add Soundproofing Layers

Making the window soundproof requires having multiple soundproofing layers. That will block or absorb the noise from outside.

However, there are so many soundproofing materials available in the market. 

That can be used with a soundproof window plug. But when it comes to effectiveness and performance mass loaded vinyl and acoustic foam are the right choice for this work.

That’s why you can use it on the plywood. But make sure to use the right quantity.

Because however, this is sound-absorbing material. But if you added only a single layer. Then this will not work very well.

That’s why earlier I have explained that you need to use multiple layers of insulation material for better use.


4. Stick Them All Together

When you get ready all the insulation sheets that you want to be in your soundproof window plug.

Then this time to stick them all together. So that you can make a proper and better structure. That’s why first you need to lay down the plywood on the floor.

Then spread the green glue throughout the board. Make sure it should be evenly spread. Next, lay the mass-loaded vinyl on it and press it firmly.

Don’t try to push hard; it will damage the structure. But make sure to remove all the air bubbles and make the surface smooth.

Now, it’s time to add the second insulation layer which will make the window plug stronger. So spread another thin layer of green glue.

Then lay down the acoustic foam on it. Again, press the whole area firmly.  


5. Start Decoration

Congratulations, you have to build your own soundproof window plug or insert. But how is it looking right now? I know it’s very bad!!!.

That’s why before inserting the soundproof plug into the space. You should try something to make it a little better.

So that it can match your house’s beauty. However, this also can be used as-is. But this is your choice.

By the way, if you want to decorate your soundproof window plug. Then you need to wait for it to dry properly.

Then you can use anything on it such as wooden paint, posters, wallpaper, and all that. It all depends on you.

Or if you want to hide it completely then you can also use soundproof curtains. That will work as a plus point for it. 


6. Install Handles

Do you want to safeguard your soundproof window plug from scratches while setting it up?

Do you want to make things easier for you to install and remove the window plug? Then you need to install handles on its very edges.

This will help you to locate it anywhere out of the frame. Also, when you want to clean your window from the inside.

Then you can easily remove it. That’s why you can use some screws and a screwdriver for this work. 

Then make a perfect hole from the drill and install it right away. Make sure the handles must be in the right direction.

Otherwise, they will hit the window frame that may cause any damage. So before putting it you should check it for good. 


7. Seal It With Weatherstripping

Installing the soundproof window plug doesn’t mean that you can completely soundproof your window.

Because this is only a seal that will help you to block and absorb the noise. But if it doesn’t install properly then it will not work well.

That’s why without adding weatherstripping to your window plug this is not completed. Because weatherstripping is a perfect seal.

That will prevent anything from passing from the cavity. That will be created when installing it inside the window frame.

However, this is a usual thing but it should be removed also. Because sound waves can travel through even a small gap or crack in your house.

But this is as big as you have under the door. This will help you in the next step also.


8. Insert It On Its Place

Now you have completed your window plug or insert. But how do you know it is properly fit inside the window frame?

This is not the best soundproof window plug until it covers the window from all the sides properly. 

That’s why now it’s time to check how well you build it. So try to install it carefully but make sure not to scratch. Otherwise, the performance will be reduced.

That’s why first you need to hold the window plug from its handle.

Then slowly slide inside the cavity and check if all things are good or not. If you don’t know, is it working well or not.

Then you can use a sound level meter. This will help you to complete this work. If all things look good then you have done a great job.
