The difference in the sound transmitted through the windows is amazing.
Our front rooms are now remarkably quiet.
The tire noise from the street is muted, along with the other noises that we have become used to over the years.
As part of our remodel over the next few months, I will plan to install more inserts.
They look great in that they do not draw attention to them being in place, and fit nicely in our 1950's built home.
I did take extra care in the measurements and the installation was uneventful, the support for the purchase was great, and the delivery and packaging was superior.
