This fall I ordered and installed five… This fall I ordered and installed five Indow Window inserts in my bedroom. Last winter (without my inserts), during the coldest of days I had my wall heater unit set near 80 degrees F, the windows were covered with ice, and I was still cold inside my room while wearing a heat and heavy wool sweaters. Last night's temperature reached -9 degrees F, and strong wind gusts chilled conditions further. I had my heater unit set to 69 degrees F, the windows had minimal to no frost formation, and I was comfortable walking around my room without a hat and only a light sweatshirt. Wonderful! Easy to place, great customer service and minimal/no impact on the architectural integrity of my 1824 home (approved by my state's historic society for use). Hands down best purchase of the year. Thank you Indow Windows!

Best purchase!!! I purchased three inserts for our primary bedroom windows. We live in a downtown area and over the years more and more development has led to increased high rises and traffic noise. I can say these inserts have drastically decreased the noise around us. Loud mufflers and reving engine noise was decreased by 90 percent! Normal outside noice decrease more than that. That makes a world of difference. I actually can sleep through the night now. Super easy to measure, order, and install. Highly recommend!

did not perform as expected. My Indow windows inserts did not perform as expected. The constant road noise from traffic is still annoying, and there is not a tight seal, I can see space between the wall and window insert corners, also there is a condensation build up on the bottom. The wait for the took for the insert arrive was about three months, but I did received periotic emails on the order status, and Mr. Reed gave great customer service.

My son’s bedroom window overlooked a… My son’s bedroom window overlooked a large grocery store and the early morning delivery noise was unbearable. I found Indow on YouTube and worked with great people to get the measurements correct, order the right type for the window, and we received it much quicker then I thought it would take for a custom order. It worked incredibly! My son couldn’t believe how much quieter it was and after ordering some noise-reducing curtains - he was able to sleep with no sound interruption. A life saver for sure.

My husband and I purchased Indowwindows… My husband and I purchased Indowwindows two years ago and purchased additional windows this year. We live in Massachusetts and own an old 1700's house. From the beginning Reed and the staff assisted us with advice on measuring the windows to assure the fit properly. They all fit perfectly! The windows have helped so much in the cold winters and look beautiful, they're perfectly clear and very easy to insert and take out if needed. This is an exceptionally great product with a great staff. Thankyou Indow ,Dan and Mary Lee Lawrence
