12 Proven Ways to Soundproof a sliding window
Here are the 12 for quieting a sliding window:
1. Hang a triple-layered soundproofing curtain
Using triple-layered soundproofing curtain is one of the affordable way to soundproof a sliding window. When we talk about triple-layered soundproofing curtains, we’re referring to curtains that are specifically designed to absorb and dampen noise.
These curtains are crafted with specialized materials that have excellent sound-absorbing properties. The secret lies in their construction, which consists of three layers.
The first layer, facing the window, is often made of a dense fabric that helps to block out sound waves. This layer acts as a barrier, preventing external noise from entering your living space.
The second layer is usually an insulating material, such as foam or fiberfill, that absorbs and dampens sound. It acts as a buffer, further reducing noise transmission through window. Finally, the third layer is a regular decorative fabric that adds a stylish touch to the curtains.
To install these soundproofing curtains, simply hang them over your sliding window and you are good to go! To maximize the effectiveness of these curtains, make sure they cover the entire window area and extend beyond the frame edges.
We recently put this 3-layered soundproofing curtain to the test, and it bring down the noise level by a whopping 24 dB. That’s a truly remarkable reduction in noise.
2. Add window inserts to soundproof a sliding window effectively
So if you want to quiet your sliding window then I recommend adding a window inserts. It is one of the most effective way for noise-proofing a sliding window.
Soundproof window insert is basically a sound reducing layer you can add to your existing windows to minimize outside noise.
Sliding windows are mostly made of glass, and as we know, sound travels through the air. When sound tries to pass through the glass of the window, it makes the glass vibrate.
This vibration then transfers sound waves into your living space. By adding window inserts, you introduce an extra layer of insulation that helps absorb and dampen these sound waves through your window.
When it is properly installed, it can possibly reduce the noise by up to 35 dB or even more, which is quiet significant.
So, if you want to sound-barrier to your old window, try window inserts! Simple, effective, and aesthetically pleasing.
3. Use soundproof blinds or shades
These guys are great for window coverings to block out external noise, effectively.
They are affordable, easy to install and remove, making them perfect solution for soundproofing window in rental and for temporarily soundproofing.
When choosing blinds or shades to muffle the sound coming through your sliding window, pay attention to the thickness and the material used. Look for thick fabrics like velvet that is designed for noise reduction.
Additionally, proper installation is key – so make sure there are no gaps between the blind or shade and the window frame when installing.
For extra insulation, you can add acoustic panels to the wall around the window area to get the most of your bunk.
4. Cover the entire siding window with soundproofing blankets
If you are not concern about the aesthetics of your window then covering it with soundproofing blankets can really be a great way to reduce outside noise coming to your room.
Here’s a step-by-step guide to do it properly:
- Get exact measurements of your sliding window.
- Buy soundproofing blankets made for windows.
- Clear the dust and dirt from the window frame.
- Next, stick adhesive strips or Velcro strips to the edges of the window.
- Attach one side of the blanket to the adhesive strips.
- And smooth out any wrinkles or air bubbles in the blanket.
These steps can be improved for better soundproofing. For example, you could layer multiple blankets or use soundproofing curtains in addition to the blankets.
My friend Sarah is a good example. She was fed up with noise coming from outside her sliding windows. After researching, she chose soundproofing blankets. She applied them following and was very pleased with the results. She now enjoys more peace and quiet in her bustling city.
5. Move some furniture around the window
Believe it or not, the placement of furniture near your window can impact soundproofing. By strategically arranging furniture such as bookshelves, cabinets, or sofas, near the window, you can create an additional barrier that helps absorb sound waves.
The logic behind this approach is based on the principle that objects can help to break up and dissipate sound waves.
When sound waves encounter furniture, they are partially absorbed, reflected, or diffused, resulting in a reduction of noise that reaches to you.
The way you arrange your furniture will depend on your room’s layout and how close it is to the window. Ideally, place larger and denser items nearer to the window since they are better at absorbing sound.
In addition to soundproofing your sliding window, you can also apply this technique to make your bay window quieter and reduce noise without having to replace the entire window.
6. Inspect and seal any gaps or cracks around the window frame
If you’re trying to reduce the noise coming through your noisy window, it’s essential to carefully inspect and seal all the gaps and cracks around the window frame. This step is crucial to effectively soundproof your sliding window.
Over time, gaps or cracks are pretty normal to develop due to wear and tear. These gaps can allow sound waves to pass through and make your place noisy.
The first step is to inspect the window frame properly. Look for any visible gaps or cracks that might be present. Pay more attention to and near the corners and edges, as these areas are often prone to developing cracks. Use a flashlight if needed to ensure you don’t miss any smaller gaps.
Once you have identified the gaps or cracks, it is time to seal them. Remember, the goal is to create an airtight seal that prevents noise from entering your home. Use sealants or caulks that are designed specifically for frames.
Apply it generously to the gaps or cracks, ensuring that it fills the openings completely.
7. Apply weather-stripping to create a tight seal
Weather-stripping is a must for creating a snug seal around sliding windows. It helps to lower noise transmission and boosts energy efficiency.
The primary purpose of weather-stripping is to fill any gaps or spaces between the window frame and the sash, glass or window slider. These gaps are common entry points for noise, as well as air leakage.
Here’s a quick guide on how to do it right:
- Clean the sliding window frame to get rid of any dirt or debris that could affect the adhesion of the weather-stripping.
- Measure the length of the window frame and cut the weather-stripping to the size.
- Peel the backing from the adhesive side and attach it along the edges of the window frame, pressing firmly.
- Test the sliding window to make sure it opens and closes without any difficulties.
Just make sure to choose high-quality weather-stripping materials. Look for options that are durable, weather-resistant and able to withstand regular usage.
8. Replace the existing glass with double pane windows
In my perspective, replacing the existing glass with double pane window is a powerful soundproofing solution that offers significant benefits in lowering the noise transmission through your single-pane window.

Double-pane windows consist of multiple layers of glass separated by an insulating gas-filled space. This design creates an additional barrier against sound, resulting in better and superior sound insulation compared to single-pane windows.
I would recommend you to hire a professional window installer for replacing the glass with double-pane window.
They will assess your existing window frame and recommend the appropriate double-pane window units based on your specific needs.
9. Build a DIY window baffle using plywood or MDF
Building a DIY window baffle using plywood or MDF (medium-density fiberboard) is a practical and cost-effective approach to soundproofing your sliding window.
This method allows you to create a customized sound barrier that helps to reduce noise transmission.
To get started, gather the necessary materials, including plywood or MDF boards, measuring tape, saw, screws or nails, drill, and some insulation materials such as acoustic foam.
Measure the dimensions of your window frame to determine the size of the window baffle you need to build. Cut the plywood or MDF boards accordingly, making sure they fit snugly within the window frame.
And I would recommend adding a few inches to the height and width of the window frame to ensure complete coverage.
Next, assemble the window baffle by attaching the boards together using screws or nails. Reinforce the corners and edges to ensure stability and durability. You can also add additional support by installing braces or cross beams across the back of the baffle.
Once the window baffle is securely constructed, you can enhance its soundproofing capabilities by attaching acoustic foam or other soundproofing material to the side facing the window.
This additional layer helps to absorb and dissipate sound waves, further reducing noise transmission. To install the DIY window baffle, simply place it within the window frame, ensuring a tight fit.
The baffle should cover the entire window area. It’s important to note that this method may limit the functionality of the window, as it prevents it from being opened or closed easily.
10. Use acoustic glass for improved sound insulation
