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!

Smart solution to very old windows rom the discovery online of Indow to… From the discovery online of Indow to the installation it was worry free. Indow staff were helpful,the printed material easy to understand. The wait time went by quickly, when delivered well packaged. Installation by my contractor had no problems. Bob was impressed with quality,ease of installation,and the sound filtering. 8 windows were installed in less than an hour. Love that can remove and clean the 1887 float glass original 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.

Bad experience Bad experience. I bought this product expecting a noise reduction which did not happen whatsoever. The only response I got is that performance can not be guaranteed. It was so frustating because they dont give you money back either. $700 trough the drain.

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.
