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.

We put 13 of these inserts into our 100… We put 13 of these inserts in our 100 year old farm house last spring and after almost a year, we can say we are extremely pleased with the results. They were a great alternative to new windows which would have been cost prohibited. The drafts normally felt on cold windy days are gone. Our home is more comfortable and the amount of LP gas used for heating has been greatly reduced. Visitors don't even notice the inserts unless we point them out. For us, the inserts were worth the investment.

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!

Costly But Effective Our Indows have significantly reduced the noise levels in our bedroom. At night, background noise is essentially zero despite living next to active train tracks. The process of measuring our windows was easy with the kit provided and installation was also very simple. The inserts did require us to remove our blinds and get window treatments which we had hoped to avoid. Also, they were pricey, but we got what we paid for and are happy with the improvement of our sleep.

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.
