I moved to a beautiful home that was unfortunately next to a busy road. Having always lived in relatively quiet areas, I did not realize how much the routine road noise would bother me. In desperation, and after a “reputable” company promised me relief, I replaced all the windows in my home. I spent a fortune, there was no change to the sound, and I thought my only option would be to uproot my family again. Then, I found Indow. This was my last-ditch effort. How could a piece of acrylic do what my expensive windows failed to achieve? I spoke with Indow on the phone and they said they could help, that the routine noise would be greatly reduced and only deep bass (think large truck engines) would pose difficulty. I live on the other side of the country, about as far in the lower 48 as you can get from Indow. They walked me through measuring, deciding which windows to get inserts for, and which inserts to get. A giant crate was delivered, everything inside perfectly packaged and unharmed from the long journey. I picked the loudest room and rolled the dice. When the final insert for that room was installed, I almost cried. Most of the routine road noise was gone, what was left was transformed from an angry roar to a sound similar to a soothing ocean. The other rooms had even better results. I can only hear the loudest of truck engines in my bedroom. Everything that Indow told me was true. In fact, the acoustic inserts exceeded Indows representations. Worried about if they work to reduce sound? For high to midrange frequencies, exceedingly well (they do reduce the truck/airplane sounds, just not as much). Worried how they look? The product is so clear that your eyes do not pick up something is in between you and the window. Worried about the cost? I spent more, went through a major renovation, and received far, far less. In short, the acoustic inserts from Indow not only exceeded my expectations, they exceeded the company’s own representations. Now that is a product I can stand by. Thank you, Indow, I can live here now.
