Must less effective at sound reduction than advertised. Much less effective than previous brand I purchased (Soundproof Windows). Will not buy again.

I'm so glad I found Indow, the room sound quality and room temperature has improved so much since installing! Thank you

Terrific product - we built a frame to create a space of four inches between the exterior and Indow. The installation was as explained in the videos. The hardest or most concerning part of the process was measuring - massive hassle if I got it wrong. However, with some practice felt comfortable with measuring and the fit is spot-on. Would recommend to anybody looking for noise mitigation and uv protection. We purchased the uv product and yet enjoying insulation and noise prevention.

We got the windows to silence freeway noise and it has been wonderful.

The whole ordering process, including delivery, went smoothly. All 13 window inserts fit perfectly in 100-year-old windows. It's made a noticeable difference in the comfort level of our house.

The windows fit perfect and look amazing! However as a noise reduction they are just ok. The noise is reduced but not to the level advertised. I tried the music behind the window and it only reduced it by maybe half not completely as shown in the YouTube video on the web page. I still here my neighbors next door.

There is a 10 degree difference between the windows without the inserts and the ones with. And they are not cold to the touch. They are doing a good job of insulating. They also cut down on noise by about 30% I'd say.

The product was as expected and it was helpful to get advice through the process.

Excellent product, will buy more. We have a house on Cape Cod built in 1800. We love the old glass and cafe windows but need storms to insulate. Because the beautiful old windows open out, traditional exterior storms were challenging. These went in easily and the fit is perfect. We intend to order more for other windows too! Really great idea and solution for us.

Our house was instantly more comfortable AND quiet! Our heat runtime was 25 hours less this January than last year despite colder temperatures, a true indication of the Indow inserts effectiveness! We have also been able to increase the humidity without condensation and ice buildup on the windows.

I ordered 17 inserts for single-pane windows in my 1893 home. The inserts arrived in excellent condition, were easy to install, and fit beautifully. My pre-installation monthly utility bill was $487; the first post-installation bill is $343! I am thrilled at the savings and enjoying my warmer home.

The Indows inserted easily and look invisible. Our concern was sound and weather proofing. It has really cut down on the noise level from outside.
Debra P
The sound reduction Indowindows have, as advertised, greatly reduced road noise and the improved insulation compared to my old storm windows is very appreciated. They came well-protected and instructions for placement were straightforward.

The Indow team was helpful from start to finish. Very responsive. The measuring process was easy. Watched the various YouTube videos by Indow for assistance. Don't assume "identical windows" have identical measurements. I was too lazy to uninstall curtain hardware from a difficult-to-access window that looked identical to three others. I measured inaccurately. Insert ended up being short on one side, but completely my fault. I added a strip of insulation there. All others fit perfectly. Arrived earlier than expected and packed to transport safely. Noticed an immediate drop in outdoor noise (live adjacent to the highway). No drafts or heat escaping during the extreme cold this past weekend. Happy with the purchase.

We received the 15 windows ordered and were able to install all of them in an afternoon without any problems. The look great and the product design is beautiful--great engineering. I highly recommend these windows. Stuart
