Home Depot’s Soundproof Windows & Products — and a Better Alternative

For most homeowners, home is a haven. It’s your space that looks, feels and even smells exactly how you’ve chosen it to. But in heavily populated areas or homes near things like airports, train tracks, or busy intersections, outside noise can disrupt your flow and bring in unwanted distractions. To help with noise reduction, homeowners frequently decide to invest in new windows from Home Depot and other retailers.

However, you might not need to completely replace your windows to help keep your home quiet and comfortable.

Why Should I Soundproof My Windows?

Acoustics matter in your home, but it’s not the first thing people think of when they’re designing their space—quite often, the way sound travels in your space is an afterthought.

But better acoustics in the home adds to indoor comfort and helps humans actually enjoy their space.

“Acoustics often remain a neglected aspect of interior design and architecture,” says Sudeep Kolte at “Although we may not think of the sound and acoustics of our home, it remains an integral aspect towards greater comfort and a better ambiance.”

Studies have shown that an acoustically comfortable home can help to make things more pleasant for your family. The benefits go beyond a peaceful, serene space, though. A quiet home helps with better sleep, improved mental health, and even lower blood pressure.

Noise Reduction Windows and Other Sound Solutions

Home Depot and other large retailers offer homeowners a few products to make their homes more acoustically comfortable. It’s important to note that while no windows are 100% soundproof, there are a few solutions that might help to drastically reduce the noise in your space.

Double-Paned windows

Double-panes are often the easy solution that is available and bought at big box stores, but they are not the best for sound performance. Plus, fully replacing all of the old single-paned windows on a home isn’t always a feasible option for homeowners.

High-performing double-pane windows can be pricey, so you might not be able to replace all of the windows at once, and even then, they may not provide the level of sound reduction you actually want.

While they are better than single-paned windows — because there are more surfaces for sound to travel through and the air between the panes acts as another buffer for noise — they may not be your best choice, especially if you have a historic home.

Some homeowners may want to keep the original, single-pane windows if they have a historic home, in order to preserve the architectural character. Many older windows are made of irreplaceable old-growth wood and replacing them with vinyl means the new windows will not aesthetically match the home. So instead of replacing the historic window, it’s suggested that homeowners opt for repairs and the addition of a storm window insert. These can be the best noise reduction option from historic windows to newly installed double-panes.

If you’re building a new home, choosing double-paned windows is a smart choice. If you have single-paned windows in your current home and you can’t replace all of them at the same time, see if you can work with a contractor to replace them in stages.

Or, to save on time, labor and money, you can use other implements with your existing windows in order to reduce sound travel.

Window Tape

Home Depot offers a few budget-friendly options for noise reduction window products, like Protecto tape. The tape acts as an all-in-one product that helps to prevent air and moisture leaks around windows and doors, and a roll of it comes in around $20. This particular product needs to be added when your window is installed. Other products, like weatherstip foam tape, can be added after your window is installed.

Tape products like Protecto are an inexpensive, quick, and easy way to help provide some soundproofing, but it’s not going to cancel out much of the sound coming into your space because there is no added insulation to the window opening. You’ll need to combine it with other products to help effectively block unwanted noise entering the home.

Soundproofing Curtains

Curtains are frequently recommended as a solution for noise-reduction in the home. Soft surfaces and fabrics can help to absorb noise in your space, and they can add a touch of style to your interior design at the same time.

Soundproofing curtains can run anywhere from $30-100. If you don’t want to completely replace your windows, the curtains act as a cost-effective alternative. As a bonus, most soundproofing curtains are also blackout curtains, which can reduce the amount of light entering the room, helping occupants sleep more comfortably.

However, while these types of curtains are better than uncovered windows, they are not a complete solution. Sound and light will still get through, no matter how high-quality the curtains are.

Many home improvement professionals recommend caulking as a way to block out sound—not just around windows, but other areas in your home that might let it noise.

“To reduce sound coming through walls and floors, caulk around light fixtures, receptacle boxes, and door casings,” writes Lisa Kaplan Gordon for Houselogic.

Caulking isn’t going to prevent all noise from coming into your home, and you’ll need to re-caulk those areas again in the future. Plus, if you don’t pick just the right color, it can be an eyesore—especially in a few months or years when it starts to crack from age.

But, by including caulking in your soundproofing strategy, you’ll add to the acoustic comfort in your home, without hurting your budget.

Window Inserts

If you don’t want to replace your old windows and options such as installing curtains, caulking, and window tape sound like a hassle or don’t meet your needs, you’re in luck. Window inserts are a great solution to help reduce the amount of noise entering your home.

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.
