How to Soundproof a Window from Outside Noise

Noise pollution is the worst! Especially on a Saturday when you are trying to sleep in after a long week at work.

Unfortunately, people cannot help but make noise. Whether it’s an obnoxious neighbour who just won’t stop playing loud music, a crying baby, construction or traffic noise, noise is kind of inevitable. However, you can protect your sanity and eardrums by soundproofing your window.

There are many ways to soundproof a window; some expensive, some not so much. An expensive way often involves remodelling, especially if you decide to install a soundproof window. Installing a soundproof window is a great idea, but not so much if you are on a budget and live in an apartment building.

So, with that in mind, we have compiled the five best and affordable ways to soundproof a window from outside noise.

Proven Ways To Soundproof A Window From Outside Noise

Window Foam/Plug

If you are on a budget, window foams are perfect for soundproofing windows. And, even better, you can do it yourself. All you’d need to do is buy the foams and attach them to your window. Or if you are into DIY, you can make your own window plug. Their thickness will effectively reduce the noise coming into your home.

Building a window plug is pretty straightforward, to start, you’d need to measure the height, width and depth of your window and then make a plug that is slightly wider than your window measurements.

The disadvantage of using window foams/plug is that they can block out light and are not exactly great for home aesthetics.  The advantage is that you can attach the window foam when the noise gets too much and take it down when the noise is not as much.

However, if the noise you are dealing with is a very loud one, the window foams may not make that much of a difference. It will reduce the noise, but not significantly. But, if your noise problem is on the minimal and you don’t mind blocking the light out for a few hours or minutes, then this is a great option for you.

Soundproof Window Curtains

As affordable and straightforward goes, that is a great option. However, much like window foams, this works great if you are not dealing with a really loud noise. Also, just like window foams you can remove or put them back based on your need of it.

However, soundproof curtains are more convenient because, well they are curtains. You can simply open or close whenever the noise heightens or reduces. They can also improve your home décor, it is a curtain after all, and naturally, you’d want to get one that enhances the aesthetics of your home.

Soundproof curtains control the noise by reducing the echo that comes into the home. They will also make your room warmer, which is great when the weather is cold.

Storm Windows

The point of this is to have another layer of glass over your window. The extra layer might be all you need to reduce the noise.

One important thing to consider when using storm windows is how thick it is. You don’t want to put a thin layer of glass over another thin layer of glass; it will not solve your noise problem.

When installed right, Storm Windows[1] can also reduce the ultraviolet rays of the sun and reduce drafts. Again, this really depends on the thickness of the window. However, installing this is not so simple, you may need professional help.

Thick Blinds/Shades

Like the above options, this option will not completely get rid of the noise, but it is effective and can play into your home décor. With shades or blinds, the thicker they are, the more they can dampen the sound coming into the room.

They are also great for keeping unwanted light out of the room, so like the above options, you’d be getting a two-for-one. Again, it’s simple to install, so you can do it yourself.


Acoustic Caulk

That is another effective way of soundproofing your window. Noise can get into your home through spaces and cracks at the borders. Acoustic caulk helps to close these cracks and keep the noise out.

There is conventional caulk available in the market, but they are not as effective as acoustic caulk. Acoustic caulk is better because it is designed specifically for soundproofing and when applied it can last for years.


Before you soundproof your windows, be mindful of their state. It won’t do you much good soundproofing a window if it’s got several panes mixing.

Also, match your window soundproofing option to your noise level. If the noise is much, then you will need other soundproofing options besides these, and if it’s not, then these should work just fine.
