I recently had my windows replaced over the weekend. These newer windows are far superior to the ones that came with the house. Ever since the windows were installed, my house has been a steady 70+ degrees despite getting as low as 20 degrees outside. This is without having to have the heating system on full blast. We recently had strong winds in the area that were sufficient to close schools for the day last Friday. The newly installed windows held up just fine. There was no extra noise and no rattling of the windows.
