Reduce Noise In Your Home with Window Inserts
Why Soundproof Window Inserts?
Struggling with outside noise from neighbors, construction or traffic? We get it. Here's a simple, easy-to-install window noise reduction solution. Just press Indow inserts into your window frames – with no mounting bracket – and be amazed at the quiet you enjoy. You'll sleep better, feel better and enjoy your space more. Noise reducing windows have never been so easy.

The Best Way of Soundproofing a Window
Our acrylic glazing edged in our patented silicone compression tubing creates a tight seal and dead air space between the insert and your window. Anywhere air gets in, noise can too. To keep the noise outside, we ensure a precise, snug fit by custom making each acoustic window insert using our laser measuring system.

One Solution, Multiple Benefits
Every grade of Indow window inserts reduces outside noise by at least 50% when placed over an operable single-pane window. Our Acoustic Grade does an even better job, reducing noise by 70%.* (If you have double-pane windows, you must use Acoustic Grade for reducing noise.) They're easy to install or remove and not only block outside noise, but also prevent inside noise from bothering your neighbors.

“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.”

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

Working with Indow has been a great experience from start to finish. They answered all our questions & guided us through the whole process. We ordered 15 inserts & they have reduced the Highway noise that we were experiencing after buying our house. A great product & innovative company.

I live 20 feet from a busy road with lots of trucks. We almost didn't buy the house because of the noise. my house is the perfect candidate for indows. After installing them (myself. .. directions were so easy) we can barely hear any trucks noise at all. Indies live up to their claim and has made a huge difference.

I am very pleased with the noise reduction and heat-trapping effects of my Indow inserts. I bought three small inserts as an experiment for the noisiest part of the house all year round, and where it's cold in winter. They have done beautifully well in sealing out both noise and heat. My only issue has been to get one of them installed perfectly straightly on one side, but it was done in a difficult location and isn't that important. They are also quiet expensive, but I may get a federal tax rebate on them.

It could have been better if the pallet was collected after the delivery. Also the inserts are more beneficial for picture/fixed windows rather than open windows. The price of insert are expensive.
Larry S
I was pleasantly surprised how well the appearance after installation, perfectly clear, plus reduce the noise from the outside more than I expected. I would definitely recommend anyone looking for noise reduction to consider these. I will be purchasing more as time goes on, thank you Indow

Called about price $1000.00 For 2 small windows asked about energy savings? They said no guarantees depending on location and almost other factors, why would I spend that money w no guarantees

It has cut down noise tremendously and is definitely more efficient with keeping our cooling in and heat out this summer.

Indow is a trendsetter in eCommerce. They make the entire process of ordering, purchasing, and installing their product very easy for any walk of life; and, their communication processes are excellent. The inserts I purchased and installed were just as described. They are effectively blocking soundwaves, but not vibration, which was discussed during my initial call with an Indow Representative. I would recommend Indow window inserts to a friend.

Our window inserts have decreased road noise in our bedroom by 75 percent which we are very pleased with. The whole process was extremely simple and organized. Everyone we dealt with was professional and helpful. The inserts were simple to install and I would recommend to others.

They make it easy to measure and install and it does reduce the noise as I live next to a busy highway. I am happy with the purchase.
Ivan L
We have a multi-story building construction next block that starts at 7 a.m. daily and a busy street a few blocks away. Before the insert was in place in our bedroom, we heard every piece of construction equipment there, including the obnoxious beeps from vehicles backing down in the lot, and all of the emergency vehicles passing by on the avenue. Now, this sounds like something happening twenty blocks away, barely noticeable. This is a huge quality-of-life improvement from day one of the insert installation.
Stan B
All fit as planned and are good
Cassie M
Overall very easy process from ordering to install. Was just hoping that the sound dampening would have been a little better.
Dan C
Effective and frequent communication from Indo Window starting with the order process, through production and post-delivery. The insert fit was excellent, fitting snuggly. The panel is quite effective in reducing noise. My wife was sleeping in the basement due to traffic noise. She is able to sleep in her bedroom again. Overall an excellent experience!
Lynett P
Great product. Arrived a bit dirty.
