We recently purchased a home and realized that our street was busier than expected and our old windows didn't keep out any noise. We purchased the acoustic Indo windows for the the front side of our home and we saw immediate and drastic improvement. As an added bonus, the Indo windows have been sealing our home from the smoke we currently have on the west coast. We couldn't be happier with the way they look (my wife is very picky about the aesthetic and she's on board!). We never expected to solve our window problem without contractors and a huge budget. We're already talking about them to all of our neighbors.
