Soundproof Curtains – Are they worth it ?

If you are looking for a quick and easy way to cancel out some noise coming through your windows then somebody somewhere has probably suggested that you try soundproof curtains.

Let’s face it exterior noise can be a real pain and if you are a light sleeper like me you’ll do everything possible for a quiet house.

Sure you can go the soundproof window route, but they can cost thousands especially if you have non-standard sized windows.

So what are your options?

Soundproof curtains also called sound ​deadening curtains are your best bet for a quick, cheap and easy DIY option.

Do Sound​proof Curtains Work ?

So do soundproof curtains actually work or are they just a gimmick?

In a word Yes!

Noise cancelling curtains do work just not in the way in which you think​

​Lets be clear on the terminology, you’ll hear these curtains commonly referred to as:

  • Soundproof curtains
  • Sound blocking curtains
  • Sound deadening curtains
  • Sound reducing curtains
  • Noise reducing curtains
  • Acoustic curtains
  • Sound dampening curtains

All of the above are effectively the same thing.


None of the above are actually “soundproof“. True soundproofing will actually block sound from entering through the material.​ 

Actually blocking a sound from entering a room would usually require expensive soundproof windows. These windows have much thicker glass than normal and usually have an space between the panes that is wider the normal.

The seals on the surround are also pretty high tech to help further reduce sound.​

That’s why they are so expensive.

Sound deadening curtains however, help to absorb the sound once they enter the room through the window.​

Choosing the Best SoundProof Curtains

The best sound proof curtains will:

  • Be longer and wider than your window​
  • Stretch from floor to ceiling 
  • Have enough material to absorb as much sound as possible
  • Look good


When choosing the best noise reducing curtains for your room you may find that there are a number of different lengths available.

As a general rule the longer the better. For the curtains to really create a sound deadening layer at your window then the best option is to mount them from the ceiling to the floor.

Mounting at the ceiling will help to hold the curtains much closer to the wall on the way down past the window.​

This means purchasing curtains that are at the very least the distance from your floor to ceiling. Preferably they will even be slightly longer so as to help reduce any gaps that may occur between either the floor or the ceiling.

Of course the exact length you will need will depend greatly on just how tall your ceilings are so be sure to take correct measurements before ordering your sound deadening curtains.

The width of the curtains is just as important as the length and it is often something that is over looked when ordering.

After all what is the point of buying curtains that are long enough to help reduce noise if there are gaps on either side of the window.


The weight of the curtains is usually a goof indication of just how thick they are. Although this will vary depending on the materials used.

As a general rule thicker and thus heavier is nearly always better.

To increase the thickness you can always double up on your curtains. When it comes to reducing the noise that passes through your windows an extra layer of curtain can make a significant difference.

Just bear in mind that if you do start to double or even triple the layers of the curtain material then you need to make sure that the curtain rail, mounting hardware and the wall on which they are hung from is capable of taking all of that extra weight.


To further help eliminate noise with curtains ​you need to be careful about how you mount the curtains.

As discussed above sound deadening curtains are usually heavier and the curtain rod needs to be able to handle this extra weight.

The rod also needs to be as close to the surface of the wall as possible to reduce any possible gaps.

Ceiling mount brackets can help to reduce this gap even further and create a better ceiling to floor seal around the window.


The tighter the curtain materials are woven together the better their ability to deaden sounds as much as possible.

A tight weave helps to reduce the ability of sound waves to penetrate the curtains.

Purpose built sound proof curtains and a number of black out curtains will have added layers that can block a lot of extra sound.

These drapes can also have additional liners that are fixed onto the outside of the material that can also help deaden any sound through the drapes.
