What Is A Soundproof Window Plug?
Many people might wonder what a soundproof window plug is, with the term being relatively unknown among a significant number of people. In short, it’s exactly what it sounds like and acts as a cover for your window that stops any sound from entering through it.
Typically, this consists of soundproofing material and foam that’s backed up by a wooden board that has a handle installed. When working properly, the plug will absorb sound waves and then reflect them back out onto the street.
This could mean that there shouldn’t be much noise entering through the windowsill. While these can be an effective solution to noise pollution, they can often be quite expensive, with this primarily being driven by the fact that many will need to be custom-made.
However, this is avoided by making DIY soundproof window plugs. Regardless of whether you choose to hire a professional or make it yourself, there can be a variety of pros and cons to using one of the products, which the majority of homeowners will need to be aware of before they start using one.

Perhaps the largest of these is that they can block out the light during the daytime, which is something that relatively few people may want.
While they can easily be removed during the day, this also means that you’ll be letting the noise in with it. As such, many people may see this as a large drawback. Alongside this, they might not be the most attractive addition to your home, especially if you make the soundproof window plug yourself.
While you may be able to add a certain amount of style to it when creating it, this will only add to the cost of the overall project. Alongside this, it could take much more time to do so. Both of these are areas that many people might want to avoid.
There’s also the fact that building the plugs could take a substantial amount of time, especially if you’re doing so for a variety of windows.

Step-By-Step Guide To Making DIY Soundproof Window Plugs
Quite a significant number of people might think that soundproofing their window will be a long and complicated process. This may end up in the majority of them may end up hiring a professional to do it instead.
However, you shouldn’t have to do so, as the process is relatively simple. As mentioned above, there is a sizable number of materials that you’ll need. You should be able to get the majority of these from Amazon, each of which should be quite affordable while still being high-quality.
The amount of these materials that you’ll need may vary from window to window, especially the acoustic foam and wooden board. However, it’s best to ensure that you know the exact size of your windows before you order the materials.
Once you have everything you need, however, you can then begin working on the project. When doing so, it’s worth putting aside several hours to make sure that you can do everything properly, although this can depend on how many windows you’re soundproofing.
With that in mind, there are few specific steps that you’ll need to take when soundproofing your windows.
Measuring The Window Area
Naturally, the first step that you’ll need to take is to measure each of the windows that you plan on soundproofing, with these measurements being vital in a variety of ways. As mentioned, this will play an essential role when you’re buying the materials that you’ll be using when creating the soundproof window plug.
When doing so, there are several measurements that you’ll need to take. While many people will know to measure the height and width of the window, you’ll also need to focus on the distance between the window and the edge of the sill.
This can be crucial, as it will play a significant role in determining how thick your soundproof window plug will be. While you may want the plug to be as thick as possible, you should leave a certain distance between it and the glass itself, as this space should help to increase how effective the soundproof plug is.
When you measure the windows, you should make sure that these specifications are as accurate as possible, as you should aim to have the final product fit as snugly as possible. Alongside this, it will ensure that there’s no wastage when you’re ordering each of the materials that you need.

Once you have these materials, then you can then start working on the project. However, it should be noted that if your windows are more than three cubic feet in size, then it’s recommended that you build a frame for the foam and mat to sit in.
Doing so will ensure that everything fits in the window properly and shouldn’t fall out. For smaller windows, however, you may not need to do so.
Building The Plugs
Once you have all of your measurements taken and the materials you need have arrived, it’ll be time to start building the plugs. The first part of this will be to cut the board to the right specifications, which will ensure that the entire window is covered and soundproofed.
To do so, it’s recommended that you draw out the right specifications on the wooden board. By doing so, you can then simply follow the lines while cutting. How difficult this part of the process is can vary depending on which type of wooden board you’ve chosen.

- Medium density untempered hardboard
While thicker boards will be somewhat more difficult to cut through, they can often be much more effective when soundproofing your windows. In the majority of cases, medium-density fibreboard is recommended, as it’s high-quality and shouldn’t take much time to cut through.
When cutting through the board, you should make sure that it fits the window as tightly as possible. Once this has been done, it’s time to cut through the soundproof mat. This should be done to the same specifications as the wooden board, with this then being attached to the board.

Following this, you’ll then need to cut through the sound-absorbing foam. While many people might think that this should be done to the same measurements as everything else, it shouldn’t be. Instead, you should make this slightly larger, which will ensure that it fits snugly into the window.
You’ll then need to attach the sound-absorbing foam to the previous two layers, either through an adhesive or some other means. When doing so, you should make sure that everything is as well attached as possible to ensure that nothing comes apart in the future.
The last part of building a soundproof window plug is to attach a handle so that you can open and close it whenever you need to. Naturally, this should be placed on the part of the plug that faces the room so that you can insert or remove the window plug whenever you need to.
After this, you should be able to place everything onto your window, and you’ll then be able to take advantage of the benefits that it offers.
As each of the above steps highlight, soundproofing your windows shouldn’t be too complicated. How much time this will take can vary from person to person, although it shouldn’t take as much time as you might expect, although this can depend on how good at DIY projects you are.
This could mean that you may need to spend a day or so on the project, especially if you’re soundproofing several windows or doing your entire house. If you’re planning on soundproofing all of the windows in your home, then it’s recommended that you aim to do so over several days.
The primary reason for this is that you shouldn’t rush the project, as this can often lead to a variety of mistakes being made. Naturally, this is something that the majority of us will want to avoid, as it could mean that some windows may not be entirely soundproof.
As such, you should spend a considerable space of time on each step, with this being especially true when measuring your windows. Alongside this, cutting the acoustic foam and wooden boards will also need a sizable amount of time, with much of this being focused on ensuring that everything is accurate.
Once you pay a large amount of emphasis on this, you should be able to make sure that everything fits perfectly and that your windows are properly soundproofed. You should also pay a considerable amount of attention to safety, as you’ll want to ensure that you don’t hurt yourself when soundproofing your windows.
Outside of this, the process should be relatively easy for the majority of DIY enthusiasts. This will then mean that you’ll soon be able to take advantage of all the benefits that soundproofing your windows brings.
