How To Make a Soundproof Window Plug

Making and installing a soundproof window plug is not a time-consuming or hectic task when you know the step-by-step process to follow. You need to read the article below to know the complete process.

1. Measure The Window

Measuring the exact size of the window is important because after this you will be taking the next steps so make sure you take the exact measurement of the window.

Measure the length, width, and depth of the window this will give you an idea of how much material is needed. so starting from the top you need to measure the length, width, and depth of the window because the window frame is a bit smaller.

But make sure you left the space between the window plug and window space that will prevent the vacuum which will ruin your work. for this work, the measuring tape is required.

This will help you take the exact size of the window and makes your next step easier wrong sizes may ruin your work so make sure you note the correct sizes.

2. Get The Material

Gather all the material needed for this process because without material this is not possible and also there are some of the basic tools which are required for performing.

Materials like mass-loaded vinyl, green glue, and plywood. Let me explain how this material works mass loaded vinyl is used to provide a soundproof layer because it’s effective and flexible.

Green glue is used for noise absorption and also for reducing noise because it is one of the cheap and yet effective solutions to soundproof. Plywood is for blocking the window because glass is not that effective in blocking noise and light.

Also, some of the basic tools include measuring tape, screwdriver, screws, utility knife, drill, saw, square, caulking gun, staple gun.

Gather all the things make sure you don’t miss out on any of those tools.

3. Mark On The Board And Cut

After you have taken the measurements to mark on the board carefully and check it twice once you cut the board then you can’t do anything so make sure you check and cut.

Don’t be in hurry to mark and cut because this is the step where most people make mistakes and again you need to start from scratch. So pay attention and cut.

But don’t worry this will not take much time if you have a cutting before then you can easily do this. So you need plywood and put it in a clean place that is not messy.

After placing it use a saw and cut it based on the markings you have marked on it. But what if you don’t have all these things then you have brought exact size plywood from the store.

4. Add Mass Loaded Vinyl

If you want a soundproof window then you need to install multiple layers of soundproofing that can block out noise from outside.

There are many materials that can block out noise and works best for soundproofing but when it comes to effectiveness and flexibility then mass-loaded vinyl is the better option.

That’s the reason you can use this on plywood but make sure you use it in the right quantity. Because it’s a sound-absorbing material that requires layers to block out noise.

If you add a single layer of mass-loaded vinyl then it will not work and do not block out noise effectively. That’s why you need to use multiple layers of mass-loaded vinyl.

  • Use for soundproofing basement, conference room.....

  • Durable and flexible

  • STC rating thick and odorless...

5. Paste Them Together

After getting all the things and cutting the plywood then you need to stick them all together. Now that you’re ready with the soundproof insulation sheets for the window plug.

Now lay down the sheet of plywood on the floor and spread a green glue on it make sure you spread it evenly after that place a mass-loaded vinyl and press it firmly doesn’t press it hard it will ruin the structure.

Make sure to remove all the air bubbles from the sheets that are paste don’t spill too much green glue put in a limited quantity.

The next step is to place the other layer of soundproof insulation that will make your window plug stronger. So spread the green glue and place the second layer.

This layer is acoustic foam and presses the whole area firmly.

6. Install Handles

If you want to save your window from scratches when installing. Do you want to make things easier than you need to install handles for easy setup?

This helps you to locate anywhere out of the frame also it makes it easy if you want to clean from the window also you can easily remove it.

That’s why you can use some screws and a screwdriver to make handles. Make a hole with the drill and install the handle to make sure the handles must be in the right direction.

If they are placed in the right direction they will hit the window frame that will cause damage so check it before installing. Now, your handle is installed which makes your work easier cleaning will be by pulling.

It will maintain a grip on the soundproof window plug that will help you to take it off for cleaning and putting back.

7. Seal With Weather Strip

Installing a soundproof window plug needs to be installed with the weatherstrip because this will help you to seal completely. This will prevent anything sound waves from the window.

Weatherstrip is a perfect seal that will reduce noise. this will be installed from inside on the edges to reduce the noise from the cavity. This is the usual thing you can remove anytime.

This is installed because the sound can travel from the small gaps and space that’s why a weatherstrip is installed to prevent the sound from transmitting through the gaps.

8. Put Back On Its Place

Now you have completed making your soundproof window plug and it’s time to insert it to know that it properly fits into the frame. To know this you need to properly insert it.

This is not the best soundproof window plug if it’s not fitted completed from inside and covers the entire window. That’s the reason it’s time to check on how well it’s made.

To check how well you made it install it by holding the handles and make sure you don’t scratch on the soundproof window plug because the performance will not be good.

Hold slowly inside the cavity and make sure to check all the goods are placed on the place to avoid any mistakes because if you missed out on anything it will not be effective in blocking out noise.

If you don’t know hope well it’s made then you can simply check this with a sound level meter that will show how much sound it will be reduced.
