I ordered Indow window since I live near the train tracks and train noises are always a bother in the morning. It helped reduced most of the noise but not all of it. I can make do with what I got. Everything was pretty straightforward with installation and measuring. Although the delivery service was pretty bad. It gave me a time frame to work with. I come find out that they came 10 minutes earlier than the time frame and dropped the Indow window off at the wrong house. They dropped it off at the house across from me. Good thing I found it in their driveway. All in all. Good windows but bad delivery service.
