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.

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!

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.

Cut bedroom decibel level in HALF. Impressed. 5 stars for a great product. I live next to a busy highway and it's been incredibly disruptive to my sleep. Indow has cut the decibel level in my bedroom by HALF. Impressed. My only gripe: Shipping took about a month, and instead of just saying "shipping takes a month" (which I would have been completely fine with) the company auto-sends an email after purchase saying "We have worked hard to absorb the supply chain issues that have affected the entire world". This is unprofessional and annoying and as dated as listing your pager number on a business card or fax number on your website. Companies need to stop blaming acts of God for your poor customer service department or slow response/delivery times. Deal with things out of your control, and stop making excuses because of them. (Especially THREE YEARS later)

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.
