I live in NYC and the windows in mothers apartment I rent are very low quality, so I could hear noise (even though I’m on a quiet street) and there was a big temperature difference on cold days in my bedroom vs the rest of the house. I ordered some Indows and even though I was hesitant because of the time they would take to manufacture and the cost, I couldn’t be happier with the decision! They came earlier than expected, they were super easy to install, they isolate the noise and the cold and my sleep quality has dramatically improved. The investment was well worth it!
