Reduce Noise In Your Home with Window Inserts

The Treble With Windows

Windows (even double paned) are notoriously bad insulators - especially against noise. Whether its dogs barking, cars driving by, construction, or any of the other noisy nuisances we encounter in our neighborhoods, windows can make it seem like the sound is coming from inside the house.

Soundproofing your home can be a challenge. Window replacement is an option for some, but can be a very costly and intrusive process and often only reduce noise by 25%. The total costs of window replacements (including labor) aren’t a great option for increasing your home’s resale value.

*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. Noise reduction will be less when placed over double-pane windows. Read our full Noise Reduction Sheet to learn more.

Other 'soundproof' options - like heavy blinds or 'sound absorbing’ curtains - will only dampen outside noise, but also block out the things your windows do best - bathe your home in natural light. This is where window inserts really shine.

Achieve Quiet With Indow Acoustic Inserts

WIth our patented Snug Fit compression tubing and premium acrylic glazing, our Acoustic Grade Window Inserts can block up to 70% of the noise coming through your windows. That’s about as close as you can get to soundproofing your windows without building a wall over them.

But the best part? They blend in with your existing window frames and let light flow in freely. In fact, if it wasn’t for how much quieter they make your home - you’d forget they were there!

Our inserts are custom cut to your exact window dimensions and require no modifications to your windows or window frames. With a provided laser measure device and our proprietary measurement software, you can rest easy knowing your inserts will fit snugly and create an airtight pocket to seal out sound, as well as extreme temperatures!

Our air-tight seal not only keeps noise out and your ideal temperature in, but it also blocks dust, pollen, and other airborne particles, but that doesn’t mean you’ll have to live in a hermetically sealed home.

Customer Stories

A loving family.

“After moving in, we realized just how busy the street was because it was so noisy we could not sleep at all. Neither could our infant. (The inserts) came on time and were installed so easily, I couldn't believe it! The difference in sound was unbelievable.”

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.
