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!

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.

Did absolutely nothing Did absolutely nothing. We can't return as the company offers ZERO garentee which should have been a huge red flag. There is no help provided by the company what so ever. Huge scam that means we are out a lot of money and still dealing with so much traffic noise making our house inhabitable. Save yourself the hassle and go with a company that stands behind their product and can provide a solution.

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!

Worth it Circa 1860s house with circa 1980/1990s windows. We ordered 14 inserts for entire home, and they made major impact on drafts and overall temperature control. Had fit issue due to one quirky window frame, and company sent replacement TWICE until it was right. Fantastic customer service, seriously. Got the standard inserts, not the noise-dampening ones, and while not the primary goal, have certainly noticed significant difference in outside sound reduction, as well. Not cheap, but waaaaaay cheaper than 14 new windows in an inflated market with some questionable workmanship right now, too.
