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.

First of all…thanks Indow!!! First of all, I am an architect and I needed Indow inserts for 3 old casement windows which had warped and are now stewed closed on an enclosed mahogany framed porch. Working with Indow was very organized and really quite straightforward. Pricing was reasonable and their checking and confirming my measurements was extremely helpful!!! Indow inserts arrived on a timely schedule, beautifully packaged, and safely delivered. The inserts fit perfectly and have markedly reduced the incoming sounds (from the above ground Subway)!!! All good!!! Hope to do additional fixed windows on this enclosed porch in the future!!! Thanks Indow!!!

We had an A++++great experience from start to finish! We had a great experience from beginning of the processing working with James Werth who helped us understand how Indows worked and led us through the process! We got our inserts for 5 strategic windows where the highway gives a lot of noise, and we are superbly satisfied with the end result. The noise has been greatly reduced as was promised, so we are infinitely happy and satisfied! Highly recommended and end product fit perfectly!

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 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.
