How To Soundproof a Window

Silence is the thing that we all love.

It’s an important thing to have, especially for the people who love to work from their home.

Noise is a very disturbing thing & can affect your focus and concentration in a very negative manner. I was not able to keep up with anything that I was doing.

As an entrepreneur, I do all my work from home & in my locality, there’s a lot of disturbance, out of which majority of it comes in the form of noise. I started to do deliberate procrastination because of this until I realized it’s not helping meg gin any form & workload started to increase as the days passed.

Now I started looking for the solution to this problem, I found out that the majority of the noise was coming from the window. I decided to fix it as soon as I can.

Here, I’m combing my experiences in the form of a blog post & the cheap DIY techniques that I used to overcome this problem.

Use curtains to block the sound

This is maybe the most obvious and easiest among all the things that I’m going to discuss here.

It’s not necessary to get soundproof curtains but the basic idea is to get curtains which are thick. if you can afford the cost of soundproof curtains, you should get them.

What I’ve seen is that they actually provide some significant results and they’ll definitely make reductions to the sound.

Use curtains to block the sound

The placements of the curtain need to be perfect so that all the noise coming through the window bounce back and doesn’t come into your room to disturb you.

One thing to note is, they won’t completely block the noise as curtains are not capable of doing that but they can certainly give results more than you would expect.

They create a type of barrier between the window and your ears, certainly not the best thing to do but it’s very much cost-effective and doesn’t take much time to implement.

Moreover, they will also work as sound-deadening material. All the echoes or reverberations that are made inside your room will also get filtered and you’ll get a much soundproof experience in your room.

You can easily find out these soundproof curtains on Amazon or you can even go to your local market and get it from there. You can but it from wherever you want, Just make sure the quality is up to the mark.

Curtains also enhance the overall look of your room. So for you, it’s a win-win situation.

Apply blinds that have thick material

This is another way to make the sound coming through your window minimal. This method is similar to the one we discussed above with more advantages as they’re more thick and rigid in nature.

Installation is pretty straight forward & any layman can do it. Most of the time if you purchase it from a local market, they’ll do the installation for you. In case you got yours from any online retailer, there are hundreds of video on Youtube to process the installation properly.

Apply blinds that have thick material

Now as these are similar to curtains, they are not going to cancel the entire sound but block some of it.

If you’re looking for something to apply in your office, I would recommend you to go with thick blinds over curtains.

This materials not only keep the sound away but also block the light coming to your room through the window. So if you’re a person who needs to have sunlight in your room, I would recommend not going with this and apply some other methods discussed below.

If you don’t want lights then it would be a great pick as this thing will keep your privacy on point as well.

Look for gaps & seal them

When I was going through my soundproofing journey, I clearly noticed that smalls gaps can make a lot of noise come to your room.

It is not an easy task to locate all the gaps & they can be very tiny at times but we’re seeking perfection here so that is not an excuse.

These gaps are normally left behind at the time of the installation of your window. It’s a very common thing to have and the solution to this is very simple as well.

Finding Tip
You’re most likely to find these gaps around the corner or edges of your window. 

Once you’ve recognized all these gaps that are causing the issue, now is the time to fix it.

One of the most common ways to fix these little gaps is to use adhesives. Usually, it comes in very cheap and acts as a good window seal.

My personal recommendations would be to go with self-adhesive strips, you can easily find online as they can be easily filtered out according to whatever dimension you want to place them.

Once you get into the detail of these small things, the chance of sound coming through your window reduces. I recommend you implement this one out.

The adhesive may come out with time.


Block the window with some furniture or an almirah

Now, this maybe is not for all the people who are reading this but if you’ve any furniture in your room then you can move around, you can definitely give this a try.

Sound as we know through science travels in the air before it reaches our ears. The more you bounce the sound waves the more they’ll lose their energy, hence resulting in less sound. This is what you can do here, Placing furniture like bookshelves, almirahs, etc. in front of the window can make the sound bounce off.

Block the window with some furniture or an almirah

One thing to note is, this will block all the light that coming from that window. If in case you want sunlight in your room, I would suggest you don’t apply this. 

If you don’t want to completely lose the light #vitaminD that you get from sun, you can place furniture around the window (Not blocking the window but around it), this way the sound will still get absorbed but the effects would be very minimal. So don’t expect anything significant from this.

In case you don’t want light & you’ve any furniture that is tall enough to cover up the window, it’s a no brainer to apply this one as this is completely free and would get the job in just a matter of minutes.

This is a very good approach as hard materials like furniture completely cover up the window & acts as an awesome sound deading stuff which can create a good impact on the sound that’s coming through.

Disturb the structure of your room


Replace with double pane windows

So this is what I personally implemented on my window as I wanted to have the sunlight & I also got some bucks that I could invest in it so I went with this method.

According to the research I did, This is a very good way of blocking the sound and this will surely work if you go with it. If we talk about estimations, it can cut off the sound from at least 50% but the only requirement here is money. If you’re ready to invest then just go with it.

Replace with double pane windows

Apart from reducing noise, it will also help you reduce the heat that comes from the sun.

Heat is different from light, It won’t affect the light that’s coming through the window that much but will surely decrease the amount of heat that gets transmitted through it. 

If you’re a person who has a window right next to the working desk then this may be a lifesaver for you as you’re getting less sound and heat at the same time. So working will be much more fun from now as your room will by default adjust according to whatever season of the year it is, that is, Hot during winters and cold during summers.

Now you just need to make sure that the installation process gets completed with perfection & no gaps are left behind, this is a fair expectation to have as you’re paying a decent amount for it.

Want more soundproofing?
If you want to go a little bit more hardcore then instead of double pane windows, you can go with triple pane as well.

You need to spend a fair amount of money


Make extra layers/ acrylic in your window

Now, let’s talk about some do it yourself stuff.

This may give you significant results but the thing to note here is, it will only work if you’re dealing with very noisy surroundings. It won’t be much effective if you’re implicating this on very low levels of sound.

Here’s how it works:

  • You first need to create a metal frame around all around the window that will hold the acrylic or the extra layer.
  • To attach the acrylic frame to the window, you’ll have to use magnets that will ensure the attachment is airtight and doesn’t have any gaps in between the window and the extra layer that you’ve just added.
  • If you’ll leave gaps in between, the noise will come through those gaps, so be extra cautious doing it.

You’ll still get light through the window as the acrylic frames are mostly translucent but some of the amounts of light will be lost and you’ll not be able to see outside world as you can see with a transparent window.

These parts can also be removed if you want to include them in your house cleaning schedule.

Let’s take a deeper look at the positives and negatives it brings to the table.

Replace it with all glass window

It’s only for the people who do not have all glass windows.

I’ve seen a lot of windows that are built around the old shutter design. (As you can see in the image below).

Replace it with all glass window

Problem with these windows is that they leak a lot of sound through them which causes a lot of disturbances in the room.

It is much better to replace them with either double pane windows or acrylic windows as they tend to provide more soundproofing. 

Talking about these old-style windows, they’re basically bad in every manner.

  • They partially allow the sunlight to pass through them.
  • Winds also get through it which carries dust with it and make the entire room dirty.
  • They tend to give very less protection.
  • Sounds can easily get through them as they have alternate openings in them.

You should take this step if you have these type of windows and you’re looking to soundproof them. There’s no other way around except adding acrylic frames as we’ve discussed in the steps above.

This is a step that I won’t recommend doing fit yourself, you should get someone to do this for yourself as this requires perfection & handling glass is not easy at all if you’re not a professional.

Cover them up with some thick blankets

Just to let you this method is similar to the curtains but blankets are much thicker than curtains.

Before going with the double pane glass, I gave blankets a shot for a few days & the results were significant.

Thick blankets are a very good absorber of sound that comes through the window, although it didn’t completely make the sound disappear but performed more than I actually expected it to be.

Cover them up with some thick blankets

You must be wondering how can a blanket help in soundproofing? Let’s discuss that with an example.

Suppose that you just came home & it’s a winter night. You brother is listening to a song with decent volume but you want to sleep. Your brother is kinda stubborn so it’s decreasing the sound. You go to bed and take your usual thick winter blanket and you cover yourself up completely. One of the best feelings, right?

I’m pretty sure you notice a pretty significant difference in the sound volume when you cover yourself with the blanket. This is because they are very good soundproofing materials and bounces back the noise.

Another example: Have you ever wondered why all the furniture and delicate things come with a covering of blanket on them, It’s because it can take damage and protects the stuff that’s inside of it. This is how sound behaves. Blankets absorb them and leave you with silence.

If you can find blankets with grommets, go with them as they’re much easier to hang along with the window than a normal blanket. This way you can replace your curtains with these blankets as they’ll be able to fit in the curtain rod itself making it much easier for you to install them.

One advice that I would like to give is don’t go with cheap blankets, It’s a kind of one-time investment so go with something good. Cheap blankets don’t come with grommets.

If you’re low on the budget, you can go with the cheaper ones and then install them manually. One of the extreme ways would be to nail them completely along with the window but that would make the window look ugly and block sunlight.

Use acoustic caulk to block little gaps

Previously I talked about how you can use adhesive tapes to fill in some little gaps, It turns out there are more things to the story. Sometimes it really breaks through my mind that how much we don’t pay attention to the small gaps that may cause sound leakage.

Acoustic caulks are very handy, they’re small and easy to operate with.

You can easily seal all the little gaps with these & amazing thing about these caulks is that they’re very durable. So they’re something like just do it once and forget type.

It takes around 24-36 hours to completely settle down, so do give it some time before making any movements around the window else cracks can appear.

However, make sure you apply it from the inside of the window as they’re not really durable under the rain and tough environments. Use them indoors are you’re good to go. They tend to be at the place once applied and doesn’t really move their position and shape.

It’s one of the easiest and effective things to go after as small things really do matter.

Make your very own window plug (DIY)

So here’s an amazing DIY thing for you. Window plugs can be an awesome way of soundproofing a window.

Wondering what are window plugs?

It’s nothing but some foam/soundproofing materials on a wooden board with handles on it that can be easily applied on a window as if it were a plug.

They serve as a very good solution to the sound leakage problem & the best part is that they don’t cost much. Making one is way cheaper.

The only cost of building it is to buy some necessary materials and that’s it.

One reason I’m recommending this to you is they are very portable and can be easily removed or applied depending upon your requirements.

However, you can not always keep it plugged in as it makes the room loo bad and for people, it’s a priority.

You must be thinking that all these things are fine, but how do I make one for myself?

Apparatus required

  • Soundproof Mat/Foam
  • Wooden board
  • Handles

How to make?

  • Get the measurements of the window
  • Build the plugs
  • Apply them

Not a permanent solution


Completely remove the window from the wall

Have you heard of this saying? – Instead of finding a solution to a problem, remove the problem altogether. (Pun intended) Anyways doesn’t sound like a bad idea to me.

If you want to go too extreme with your soundproofing journey, remove the window. Yes, I’m being serious here.

This will give you the best experience as it’s nearly impossible for the noise to go through the walls.

Completely remove the window from the wall

But before you call someone to get it done, Make sure that you really don’t want the window. Some people like to enjoy the view and the light that their window brings to there room & for them this may sound offending.

If you’re a type of person who doesn’t really care about the light that comes through it or the ventilation it provides then removing the window would not be a big deal for you.

It is going to cost you some money but to be honest, It’s a one-time investment and you don’t really have to do anything after that.

Sit down, think about do you really need the window & make your own decision.

A final verdict on soundproofing a window

Personally I had a lot of fun doing all these DIY things on my window and sharing the results with you guys. I’m pretty sure you would feel the same as well after doing something for yourself.

These methods helped me to soundproof my windows and focus more on my work and less irritation at night because of the street noise.

As I discussed earlier, I went with the double pane method as I want to enjoy the sunlight that comes through the window and beautiful & abstracts views of the outside world. It’s not the only thing that I’ve for soundproofing the window but I also added a thick curtain on top of my window so that I can enjoy it’s an extra benefit as it helps as a sound-deadening material.

Now It’s your job to get the right thing implemented for yourself. Some ways aren’t guaranteed to give results but combining multiple things together will surely make a significant impact on the level of noise that gets through the window.

I made sure to include solutions that anyone can easily implement without stressing their pocket too much.
