"We purchased an Indow insert so we could keep our beautiful original 1939 leaded glass window. Our goal was only to stop drafts. It not only stopped the drafts, but it also decreased street noise. We did not expect this benefit, what a pleasant surprise." — Darci M.

Great product, well made. Helpful staff and great communication

The window fits perfectly and was easy enough to install by myself. It unfortunately does not reduce much noise, if any at all, from outside, that might be something for the more premium versions. I have noticed that it does help keep in warmth however which is nice.

They are wonderful and are keeping out the cold air this fall!

I love my Indow inserts! The installation was very simple and the Indow team helped me the entire way. I live near a busy road, an interstate, and an airport. Although not unbearable the noise from those aforementioned sources was noticeable (key word "was" :) ). I am so glad I found Indow because their inserts were affordable, not permanent, and easy to install. The Indow inserts significantly reduced the noise! I don't have official measurements but I'd say the inserts cut down at least 50% of the noise which is a huge improvement!

I am a 78-year-old woman and the windows in question are above two sliding glass doors. All 4 are almost 3'x4' in size. I had absolutely no problem ordering and installing them myself. The Indow rep I worked with initially answered all my questions. Indow helped all the way with the measurements, delivered the indows early, and provided detailed instructions on their installation. My only advice to potential customers is to measure thrice and order once. The key to successful inserts is a perfect fit - with the Indow-supplied laser, you can do it!

Great quality & service. Inserts are a good fit. Will be able to give better feedback after we have been hit by severe winter weather.

Great product, fit and finish was high quality. The difference of road noise was amazing. I rarel. Hear vehicles any more. Before it sounded like they were going to drive theough the wondow. Great invention!

The inserts weren’t too difficult to place and have made a huge difference in reducing outside highway noise. Love that they are barely noticeable once in place so don’t detract from the window view or appearance at all.

Wow! A company that is honest and transparent about their terrific product. Thank you! Received my window inserts this morning. They work well cutting road noise dramatically. Easy to install. But most of all doing business with them has been an uplifting pleasure. Warms my heart to see honest,dedicated people making the world a more peaceful place!

From start to finish, working with Indows has been a great experience. They made sure that the measurements I took were accurate so that the finished product fit perfectly. The Indows, definitely reduce the sound out on the street. In a small guest room inn our Inn in San Francisco, the need to open the window and air out rooms is a necessity so we will see how suitable the inserts are in the long run.

I am very grateful to have found and purchased Indow dor several problematic windows in my 1909 house. Wanting to retain the stained and other leaded design windows but making them more weather efficient, Indows solved the problem. I just popped them in and viola! Service was also terrific. I do have to adjust the seal occasionally on one of the picture windows but it is no problem.

Our 9-pane living room window was letting cold air in, so we purchases 9 Indow Window panels. They were fairly easy to install and have held up for a few years now. They make a huge difference in comfort in the living room. Great idea you had there!

The ordering process was smooth and easy. Window arrive we'll packed and clean. Installation was easy but the safety chains make no sense.

I work five nights a week and keep night hours on my days off, so having a pitch-black room is essential to my health and happiness. After reading some reviews I settled on the Indow sleep panels. My house was built in 1901. I have two bedroom windows that are about 6' tall and 3' wide. From the time I got in touch with Indow, through the measuring process, through the production and delivery of my inserts I felt like they were supportive. Reading the installation guide before their arrival was essential in preparing me for the process. I knew I'd need to install window brackets with a power drill and that unboxing the inserts might be a bit of a chore. This made the installation process smooth which I greatly appreciated. The inserts arrived a few hours after I'd worked through the night, so I was ready to get them installed in short order and get to sleep at a reasonable hour that day. As to their efficacy, the panels block all the light. The sound dampening isn't powerful, but I knew that going in as well. The inserts need to sit 4" from the glass for the full dampening effect and mine can only sit at about 2". There is a dampening effect, just not at the 50% noise reduction that they're capable of. The delivery service that shipped to my house didn't call to schedule the delivery as the instructions said they would. That's the only thing that didn't go according to plan, but I was home so it worked out. Other than that one thing, the panels perform as I hoped they would. I'm grateful for my dark room and my consistent deep sleep because of them. I would work with Indow again in the future.

We love our new inserts. All nine fit perfectly in our varied windows and now we can enjoy a warmer and quieter winter. Indow was fantastic to work with through the entire process. Thank you, Indow!
