We LOVE our five Indows and we are getting ready to order eight more. We needed Indows because we have an antique home (mid 18th century) with single pane original windows that cannot, due to historic value, be easily replaced. We are also right up against a loud, busy road, and we’ve had furniture ruined by sunlight. Since Indows improve heat retention, noise reduction, and block UV, they were the perfect choice for us. Measuring, ordering, and installation were a breeze. We’ve had them about a month now, and they have changed the way we use our living room. I no longer worry about my new red couch fading, my daughter can hear her school Zoom calls better, and I no longer have to wear a shawl when sitting near the windows. It’s significantly warmer and quieter compared to the dining room, which will be Indowed next. We are extremely happy and satisfied. Thank you so much!
