Soundproofing windows can be done in a number of different ways:
- Getting panels that sit or hang in front of windows
- Adding sound dampening plastic film
- Covering the window with noise reduction curtains
- Adding another window on the interior frame
- Upgrading to double (or triple) pane windows
- Ensuring there are no gaps around the edges
You could even combine a few of these different methods.
Let’s look at a few in more detail…
Use An Acoustical Grade Window
One of the top-rated windows is the Quiet Line Series by Milgard. They are commonly used near airports, highways and other high-noise parts of town.
This is the most expensive of the options, but also the most permanent and aesthetically pleasing.
Use Noise Reduction Curtains
A side benefit if you’re going after reduced sound is that these typically block out light and heat as well.
Noise blocking curtains can be used on almost any window and are great for rentals because you don’t need to replace any windows and you can take them with you to the next place.
A possible downside (depending on the use) is that in order to block the sound, you have to block the light as well.
You can also get a liner to add to your existing curtains to help with sound and heat.
Window plugs are removable mats/boards that sit in front of windows and block both sound and light. Check out this DIY guide on making a heavy duty window plug.
There are also panels that hang or attach to the inside of the wall in front of the window.
Seal Gaps In The Frame
Gaps in the frame (even if you can’t see them) can let a lot of sound through. Check out the post on how to soundproof a door for some tips on how to soundproof the frame.
