Soundproof Windows Cost: Are They Worth the Price?

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.

If you think installing window inserts is the right method for you, there’s no smarter or greener choice than Indow.

*We want to ensure our inserts help solve your noise problem. Overall noise reduction depends on the amount of noise coming through your walls, ceilings, floors, doors, and existing windows.

Indow inserts were easy to measure, order and install. They've provided great insulation for old single-pane and stained glass windows in an antique home. We can significantly feel how much better the home holds heat.

I ordered two Indow inserts for my home. They are doing a great job, entirely happy with them and the ordering process.

I can't say enough good things about this product and company. Our house is 101 years old and the sidelites next to our front door are single pane ancient wavy glass which means when it gets very cold (Chicago temps) we can have an inch of frost covering the INSIDE of our windows. I was desperately searching for a solution so our front vestibule was not so cold and a friend recommended Indow. The process could not have been simpler and the temperature difference it has made is off the charts.

I have several historic single pane gridwork mullion windows. They're beautiful but have almost no thermal protection. Indows proved to be the perfect solution to preserve these windows while getting the thermal comfort we need. They were easy to install and work perfectly!

Amazingly easy to install even the safety chain holders. I. Noticed an immediate sound level difference and the room atmosphere became more solid feeling and pleasant. They also gave an insulating feature to the window drafts are non existent! The house is 50ft off a State highway that is heavily traveled in warmer months I'm confident the indows will handle it. I'm very pleased!

We ordered the acoustic inserts to help with road noise, and we've been sleeping so much better with them!

We used the windows inserts in our skylight. They are great! They the horrible drafts and noise out and were cost efficient. My only comment would be to provide better measurement and installation instructions for skylights specifically. It took us a lot of guessing and research to measure and install because skylight directions were not provided and the windows install guide doesn't always apply to skylights. Other than that though great product and I would buy again!

Our home was built in the late 1800s and we have spent a lot of money over the last 20+years restoring it.We did not want to replace the windows with modern windows because of the cost and originality. But the single pane windows come with a price also. the main reason we purchased the Indow window inserts is because of the condensation on the inside of the windows.We would literally have a take a towel and wipe them down every morning in the winter. There would be a puddle on the sill,and wood and water dont get along to well. SO we looked into the best solution to our problem and found Indow. Was reluctant to spend that much money but am super glad we did!! They have been installed now for over two months and our condensation problem has been virtually eliminated.!!! AND our furnace does not run as much as it did before. Over all it was money well spent!! The process was a little scary at first but they have a simple formula. And our contact person,Reed was awesome. Answered any questions i had and was always available.

Used to block interior side of a garden window in the the kitchen. Without insert, cold air literally poured into the kitchen making a winter jacket almost mandatory when preparing meals or washing dishes

Highly recommend! The team (Brian) took time to help me figure out the best solution. They were made and delivered faster than expected. It was very rewarding to install them because I could feel the cold air get squeezed out as they went flush against the single pane of glass. Solid quality and great fit.

My inserts fit beautifully into my 125 year old windows - many of which were 5 feet tall. Easy to unwrap and install. Great product and even better service! I liked the process of measuring the windows with a laser measuring tool which was easy to use and precise. The product came in good condition after shipping across country and was well marked. The customer support was excellent.

Received our Indow Windows and can tell they are blocking a lot of the noise we could hear. Right now the weather is mild, but hoping to notice a big difference when the summer heats up. Our house is in a historic district and we cannot change our windows. They are very drafty and thin glass. We only ordered two, but we are in the process of ordering for four more. Love that we don’t need to drill holes or anything and they just pop right in.

Every thing arrived in perfect condition, thanks to the very secure packaging. Windows fit as expected, although quite tight. After installation we noticed that the cold drafts were gone and the room felt a lot warmer. We are very satisfied with the product and the result.
