Indow window inserts literally changed our life. We moved to the a perfect place that we are in love with, but only after the move we found out that with the highway being really close to us the early traffic noise was awful. For the first weeks we had really bad sleep and felt miserable. I found out about Indow and hoped that it would help us keep enjoying the house we love. To be honest I wasn't expecting them working so well. Sure I hoped it would reduce a lot the noise coming in, but I couldn't believe how peaceful and quiet my room is. I can barely hear a little bit of the morning chaos, and during the rest of the day the room is not only quiet but a lot cooler in the summer. Mind these are floor to ceiling oversized windows and the inserts fit perfect, blend well and are not an eyesore at all. I'm really glad we found this, I can say I am a happy customer!
