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 Housing.com. “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.

From start to finish, we were very pleased with our rep, Reed, and the other staff at the PDX will call! The inserts themselves are stupendous! We purchased six total for the noisiest, road side(s) of our home. The outcome was beyond our expectations! Not only did the three rooms that bordered the road become at least 70% quieter, the other end of our home did as well! I cannot recommend Indow inserts more! The technology makes sense to add the inserts rather than purchasing new windows. Great results and thank you! Paul and Paula Spilsbury

Brian was very helpful & informative. He helped me order the correct windows for my needs. They were shipped with the utmost of care & arrived ahead of schedule. Ultimately, the Indow Windows have been very helpful in muffling unwanted noises & they have helped save on our energy costs. Thank you, Indow Window!

We are thrilled with our Indow window inserts! I'd been on the lookout for a more permanent solution to leaky windows in our third floor living space. I discovered Indow on social media but since then have learned of friends who'd had Indow recommended to them by their rennovation contractor. The entire process went smoothly with friendly reps at hand to talk through questions during measuring, etc. They fit perfectly and help us to maintain the beautiful design of the windows on our 100 year old home! Highly recommend!!

For townhouse living, this solved my problem with noise from my neighbor's with my kitchen window. A considerable decrease of noise indeed! Measurements were a bit frustrating so I recommend using a laser measurement device and following directions to use a string for the diagonal. They look great and were easy to push into place. I highly recommend as an alternative to buying a new window.

The process could've been smoother with the sending of the measuring kit. There was a delay with weather in Oregon but then it felt like my kit was still delayed due to other reasons. Most new homes (like mine) have textured paint and it can also be inside your window frames. I measured everything out but I still have little tiny gaps due to the texturing. Not indows problem but just be aware you made need to sand or fill in those gaps yourself to get a perfect seal. I did the acoustic grade inserts and they have reduced some noise but they will not completely block or significantly reduce road noise. This is most apparent with deep or lower frequencies like truck exhausts or modified street racing cars that are quite popular these days. Taking the inserts out to open your windows isn't an easy task. The little metal hook they provide needs to be either bigger or you can attach something to it as a way to leverage yourself. Overall the process was average. I think they're definitely a good option for weatherproofing and some sound reduction depending on the type of windows you have. I would purchase again.

The process for ordering and installing the Indow Widnow inserts was so easy. They sent the measuring information and it had great instructions. The inserts were delivered by UPS was crushed on one corner, but the company had packed them well, so there was no damage. We installed them the same day. It works best if you have two people completing the installation. We felt the results immediately and are glad we spent the money to make our home just a little more efficient.

Our home was built in 1913 and has beautiful old wavy glass single-paned windows. I’m so glad we were told about Indows and didn’t have to replace the original windows. We live in Canada but had no difficulty placing the order and were very impressed by how accurately the company met its deadlines, including cross border delivery. The Indows inserts blend in perfectly with our home and the existing window frames. You don’t see them unless you’re actually looking for them. But what we did notice was how much warmer the rooms feel the minute the inserts were installed! I can’t speak to any heating bill savings because they just went in this week, but our home feels much, much cozier. Our contractor who took all the measurements and installed the Indows says: “Excellent instructional videos: clear and informative. Very impressed with the design and the product. Overall, the ease of installation is quite impressive. Working with all the staff at the company was great – everyone was very helpful.” I’m already recommending this company to any of my friends who live in drafty older homes and want to reduce their heating/cooling bills and do some good for the environment.

Don't be afraid of buying an older home with single pane windows. This company has you covered. Their inserts are super high quality and fit well thanks to the laser measuring kit they send. Highly recommended!

We purchased three Indows to reduce drafts and noise in our bedroom, which faces the street. The improvement was immediate. Our house was built in 1958 and although we have exterior storm windows we didn't want to replace the windows outright due to cost and architectural consistency. These were an excellent solution.
