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.

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.

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.

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.

New windows are really expensive and… New windows are really expensive and can ruin the look of a house. These Indows are not the cheapest inserts on the market, but they are really clever, do not require permanent frames, are made very precisely (none of my hundred year windows were still square) and our home was a lot warmer this winter because of them. Replacement window salespeople promise the world in terms of ease and energy savings and rarely deliver. These are such a simple alternative that do just as good a job.
