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!

I have a bank of three heat pumps right… I have a bank of three heat pumps right outside of my bedroom/office window which are noisy. It made sleeping and working in the room difficult. The Indow inserts, combined with padded drapes, make sleeping and working significantly easier. The step-by-step process was relatively simple, and the sales rep, Brian, was helpful. Thank you Indow!

Saved our house!! Saved our house!!! We just bought a historically significant home in Indianapolis that is unfortunately located on a very busy street, Meridian St. The front rooms of the house were uninhabitable because of the traffic noise so I took a gamble and ordered Indow windows for the front master bedroom… Indow windows have saved our home!!! We are able to sleep without any disturbance of traffic noise. My daughter says her ears ring from silence.

They work! They actually do work surprisingly well! Don't expect 100% noise reduction, or you will be disappointed. But there has been a significant drop in the road noise in the rooms where I bought the windows, such that it does not bother me anymore and I tune it out. The installation and measuring process were a lot harder than advertised, recommend getting a handyman to help.

Super easy to install I ordered these for a home which had lost all of its original interior storm windows to foolish previous owners. The measurement kit was easy to use and all of the windows arrived intact and fit properly. I probably spent more time getting them out of the box than I did installing them. I purchased mine for additional insulation and I look forward to the reduction in cold drafts this winter.
