1. Ladder or Sturdy Stool
Installation is EASIER when you can reach every part of your window. This is particularly necessary when setting the grommets of your soundproofing curtains, soundproof blankets, or blinds.
Curtains are commonly LONGER AND HEAVIER than soundproof blankets. They fully cover your windows, starting a few inches above the panes. These are hard to reach places, so make sure your ladder or stool is safe to climb on. It is best to have a friend help you out.
They can be visually appealing, too!
A HAMMER IS NECESSARY to thoroughly lock mounting hardwares when installing noise cancelling curtains, blinds, or shades. Most soundproof curtains or blinds already come with screws in their kits. You might also need a measuring tape and a pencil to mark where you should be hammering.
3. Thick Soundproofing Curtains
The thickness of the fabric material will determine the quality of sound absorption. The more layers, the better the sound barrier. Blackout curtains, for example, are a fantastic choice because they help with light pollution.
4. Thick Blinds or Shades
Similarly, these reduce echoes and sound from the window.
They reduce sound transmission and unwanted vibrations coming through the window, thus cutting sound waves from traveling. Thick blinds or shades are best paired with soundproof curtains.
5. Fiberglass Soundproofing Panels
Thick materials like ACOUSTIC PANELS have great soundproofing qualities. This acoustic grade glass sheet is heavy weight aids in blocking the amount of outside noise. A single layer can already work wonders!
6. Acoustic Caulk
It’s inexpensive and can seal gaps. This blocks the small pathways and prevents sound from pushing through. They usually come in the form of a caulk gun and can be bought in most hardware stores.
7. Weatherstripping Tape (Foam, Rubber, or Silicone)
These are great at filling the gaps between existing windows and the walls. They block noise from entering through an air gap, thus leading to sound reduction.
8. Window Plugs
Soundproof matting and acoustic foam are EXTREMELY USEFUL in creating a soundproof window plug. You’ll also need wood to build the frame and box with. A soundproof window plug make a good DIY project since it’s easy to build one on your own.
How To Soundproof a Window: A DIY Guide For You!
Method 1: Block The Window Entirely
Blocking a window entirely will GUARANTEE the reduction of all the noise pollution. In this case, you won’t be able to use that window for a lot of light coming into your home.
If you don’t want to spend extra cash, you can use EXISTING FURNITURE IN YOUR HOUSE to cover that window. Like a cabinet perhaps.
You can also take out the window entirely and replace it with a wall. This will UNDOUBTEDLY get rid of the outside noise. But you have to understand after doing so, you will not have a window at all.
Before choosing this method, consider every possible option. Besides, there are seven other more methods for you to choose from in this article! Keep reading.

- Allows minimal to no light from coming in
Method 2: Add an Extra Panel to the Windows
Window soundproofing often requires an EXTRA LAYER of laminated glass, especially when your windows are single pane windows.
You can go for insulation panels, acrylic panels, or window inserts.
Some of these DIY window soundproofing solutions come in magnetic frames, easing installation. They’re also VERY AFFORDABLE and usually come in kits, making for a CONVENIENT SOUNDPROOFING WINDOW KIT option.
- When purchasing a window panel kit, get all the necessary components and specific instructions. Make sure you have the correct dimensions of the aluminum frame to match your whole window.
- Mount the aluminum frame of the panel to the interior side of your window frame. You don’t require a lot of tools to install them. You just need to press them to the sides and slide them back.
- Each frame already has weatherstripping around its perimeter. This should seal the existing window.

Method 3: Seal All The Gaps and Cracks
Even the SMALLEST GAPS AND CRACKS will let sound inside the room. It is important therefore that these are TIGHTLY SEALED to make a soundproof window! Here are some options:
As mentioned above, these tapes come in various forms and materials: Foam, Rubber, and Silicone. This option is FAIRLY INEXPENSIVE and EASY TO APPLY, but will require periodical replacements.
- Consider which material suits your windows best depending on the amount of friction your window receives, exposure to weather, and overall look.
- Clean the window surface.
- Cut a strip to the desired length.
- Apply the strip to all four sides of the inner frames of your window jam.
These come in packaged strips and is also an inexpensive way to solve sound reduction.
- Cut strips down to match the length of seams on windows.
- Manipulate and press each strip into its respective seams.
This is a little more durable compared to acoustic caulk. This comes as a caulk gun or shooter foam gun.
- Apply an even bead of caulk along the entire exterior seam. This sealant blocks moisture from coming in too.
- When using the expansion foam, test the volume with a small drop first before going all out. This way, you apply just the right amount.
Weather Seal Tape
This method only lasts for several months. You will require replacing them regularly. If the cracks get worse, it’s the best thing to have replacement windows instead.
- Cut a small strip of clear weather seal tape.
- Put it over the crack in the glass.
- Low cost
- Will require regular placements
- Does not completely make a soundproof window
- Combine with other methods
Method 4: Install a Quilted Fiberglass Panel
If you want to EFFECTIVELY REDUCE window noise, the thicker and denser the material you use, the better!
Quilted fiberglass panels DEFINITELY ARE A WINNER in sound reduction, especially for avoiding unwanted outside noise inside your home!
A panel with dense materials that is four feet wide, eight feet tall, and two inches thick weighs around 12 pounds. The weight of the laminated glass panel is ideal to lay flat against a window.
This way of window soundproofing is significantly more effective than curtains. But for maximum noise reduction, you can install both.
- Install heavy-duty hooks around your window panes.
- Insert the panel into its metal-reinforced eyelet holes.
- Attach edges using strong velcro for maximum window soundproofing.
- Highly effective at reducing unwanted noise pollution
- Less attractive than curtains
Method 5: Install Soundproof Curtains
Another way to make a soundproof window is to get thick soundproof curtains. This way alone won’t block noise entirely, but it can be a USEFUL COMPLEMENT to other soundproof methods.
These curtains help absorb sound and reduce echo. It can also be a great addition to your home decor.
It suits well with your window opening and allows you to manage how much light and insulation you want. You’ll want to buy LONGER AND THICKER curtain material, though! You can also layer more than one curtain to soundproof windows better.
The absorbance of sound will depend on the density of the fabric.
- Measure the width of the curtain and the distance between each grommet. This will tell you where to hang the mounting hardware.
- Install the mounting brackets into the drywall, where the grommets will interface the wall. You will need a ladder or sturdy stool to reach the top of the window. A hammer is also necessary to mount brackets.
- Hang your soundproof curtain.
- Reduces the echo and sound
- Keeps light away as needed
- Aesthetically complements your window

- Will not reduce noise completely
Method 6: Pair with Thick Material Blinds
To successfully soundproof a window, you also have to prevent vibrations from getting into your room. Just like curtains, they reduce the impact of echoes.
Adding a barrier such as thick blinds or shades will make a SIGNIFICANT DIFFERENCE in solving your noise problems.
The best type of blinds as a soundproofing solution is honeycomb double cell blinds. These are blinds that OPEN UP LIKE AN ACCORDION when you pull them down!
- Installing these blinds is like installing curtains. You will need a ladder or sturdy stool, as well as a hammer.
- The top of the headrail must be marked on both the left and right outside edges of the shade. Using a pencil, measure a distance of almost 2-2.5 inches from each side.
- Fasten screws with a hammer.
- Using the supplied screws, align and fasten the top of the left and right brackets with the pencil-marked areas.
- Fit the front of the bracket into the headrail. Then, snap it into place by pushing the back portion in the right slot.
- Use your cords to test whether they are functioning properly.

Method 7: Make Your Own Window Plug
This is a DIY project that will DEFINITELY keep you busy! A window plug is a simple frame designed to provide an airtight seal for your windows.
A window plug is easy to build and made of inexpensive, yet highly effective materials. They are often considered window inserts too.
These work by filling in any space in front of your windows with layers of acoustic foam, soundproof matting, and wood. This way, the foam absorbs the sound waves, blocked by the mat, and the wood backer board.
- Measure the depth of your windows to determine the maximum depth of your window plug. You’ll want your plug an inch or two lesser than the whole depth of your windows.
- Measure the length and breadth of the gap to fit in. The plug should snugly fit in your windows for greater prevention of noise pollution. Be as accurate as possible.
- Build a wooden frame with the exact dimensions. Make a cross support to strengthen the frame.
- Cover the frame to form a box with two half-inch MDF sheets of 1/2 inch thickness.
- Add insulation inside the open box. The insulation material must be of low-density fluffy fiberglass. This is ideal for soundproofing windows.
- Seal the box with the other sheet of MDF.
- Glue a thin layer of felt tape along with the existing window frame. This will provide a better fit for the window plug and avoid window scrapes.
- Attach two handles on the front of the side of the window plug. This way, you can easily mount and remove it to and from your windows.

Method 8: Replace the Windows with Double-Pane Windows
Now, this method is perhaps a BIG DECISION to make.
This soundproof window will take a fair amount of money. It will also require you to hire a professional to install it. This solution will GUARANTEE to block out unwanted sound/noise pollution definitely.
Upgrading your single-pane windows to double-pane windows, or even triple-pane windows can minimize noise level by 50% OR MORE! It is known how well-efficient these double-pane windows can be. Even more so for triple-pane windows.
Other than sound blocking, these double-pane windows also keep your room cool during the summer, and warm during the winter. This way, although you shell out a bigger investment initially, you SAVE UP A LOT on the energy bills.
It is important to hire an expert/professional who knows how to soundproof a window with the use of triple-pane or double-pane windows. There should be no gaps or cracks left around the edges of your windows to make sure no unwanted sound comes in.
A poorly installed soundproof window will waste your time and money. Might as well not hold back in spending A LITTLE MORE on an expert installer.

Personally, the best method for us is a combination of two or more methods. We would initially seal all the gaps around, and cover any cracks.
Second, installing an additional laminated glass panel does the trick. We prefer this method since it’s EASY TO INSTALL AND REMOVE while allowing sunlight to come in when we work during the day.
Lastly, installing a layer of soundproof curtains and blinds for additional barrier of soundproofing, which will also be decor for the living space.
These are all great solutions. It all depends on how much outside noise you’re dealing with, the size of your budget, and how much more time you can invest.
