man installing window insert to block noise and drafts

In a world that’s getting noisier every day, peace of mind is becoming more valuable — and yet harder to find. Whether it’s the city traffic outside your doorstep or the noisy freeway a hundred yards from your backyard, it can seem impossible to find a quiet place even within your own home. That’s where soundproofing comes in. 

Soundproofing isn’t always a cheap remedy, but it is always a worthy one. Let’s review what soundproofing is, a few different soundproofing methods, and finally, which soundproofing method meets the best balance between staying under budget and getting the job done.

 Why Soundproof?


In order to answer that question, we need to examine what soundproofing is meant to protect against: noise pollution. Not as obvious as light pollution and not as scary as air pollution, noise pollution is easily overlooked as just another side effect of urban living. However, noise pollution poses significant health risks that should not be ignored.

Studies have shown that consistent loud noise can lead to increased stress and subsequent heart problems. According to the National Center for Biotechnology Information (NCBI), noise pollution causes sleep disturbances, cognitive impairment among children, and even tinnitus. We all know how just one bad night’s sleep can ruin a day, so imagine struggling to sleep every night due to noisy disturbances (if you’re reading this, you probably don’t have to imagine). 

The windows of your home are the main vectors for noise pollution. A thin layer of glass can’t block out nearly as much sound as a brick wall or a roof. 

One-time fixes like noise complaints might work for loud block parties or for the aspiring musician living on the floor above you, but you can’t file a noise complaint against an airport, garbage truck, or city traffic. At the end of the day, noise pollution isn’t going to go away anytime soon, but that doesn’t mean there isn’t a solution. That’s where soundproofing comes into play.

What Is Soundproofing?

Soundproofing can be one of two things: keeping unwanted noises from getting inside your home or neutralizing the unwanted noises that are already inside your home. Respectively, these two different methods are sound reduction and sound absorption. Once you’ve determined which method you need, you can choose the best soundproofing materials to pair with the most effective method.

Sound reduction, the most popular goal, means keeping noise out. To achieve that goal, soundproofing your windows is the key, and there are three options. 

1. You can do a full replacement and install double-paned or even acoustic-grade glass and frames, but the process will be long, costly, and messy. 

2. You can install soundproofing curtains as a quick, extra layer over your existing windows, but this will reduce the amount of natural light that enters your home. 

3. You can install window inserts, a fast, easy method that is less invasive and costly. 

All of these options are perfectly valid in terms of keeping the noise out, but they do have their drawbacks. Let’s go through them and compare their prices and efficacy.

Replacement Soundproof Windows

For many people, a full window replacement is one option that’s often suggested: just buy the best and forget the rest. However, assuming that you’re upgrading to double-panes, not counting installation, a full window replacement will cost up to $600-$800 dollars per window. And window replacement isn’t always the best option.

When factoring in installation, soundproof windows cost upwards of $1,000. Houses with non-standard windows can incur even higher prices for reinstallation because the replacement windows and frames will need to be custom-made. The good news is that, when all is said and done, you will have some sound cancellation for your home (though there are options that provide better soundproofing) — though your wallet will be much lighter. 

Soundproof Curtains

Soundproof curtains are a tempting option for many homeowners. They satisfy that do-it-yourself crave, they’re easy to install, and they’re cheap, usually running in the $50-$200 range. Sound-canceling curtains are not nearly as effective as inserts or replacement windows in terms of blocking sound, but they are more versatile. 

Soundproof curtains can be moved around the houses to trouble spots when needed. They can also be hung directly on the walls and function as sound absorbers. If you’re looking to put some padding between your daughter’s garage band and your home office, these just might do the trick. 

The only big downside with curtains is that, well, they’re curtains. When they’re closed, they block out sound but also natural light. You can always open the curtains to let in more light, but then you’ll be letting in the sound, too.

Soundproof Window Inserts

Window inserts are the unsung heroes of soundproofing materials, and they’re very simple to install. As the name implies, you just insert them within the window frame behind the existing window pane. They can be moved in and out of position with ease, and certain brands like Indow offer up to 70%* sound reduction in addition to added insulation — saving you energy and money.

Window inserts are far cheaper than full-on replacement soundproof windows. They typically cost about $30 per square foot, equaling around $350-$450 per window, but they can be installed by the buyer and are easily measured to fit any frame in your home. Ultimately, window inserts are not a middle-of-the-road compromise, but a fusion of the adaptability of soundproof curtains with the soundproofing abilities of replacement windows.

If you are worried about the cost of a window insert, consider what you are willing to pay per day for the benefits of reduced stress levels and improved sleep. Divide the total cost of the window inserts by the time you spend in the space. And if you share the space with one or more people, divide by each person. The result is a tiny daily cost that greatly enhances your daily life and happiness.

You can also consider the overall value of your home. Homes with noise issues are much harder to sell (and sell for smaller amounts) than a home with noise controlling window inserts.
