We turned an old broken down porch into a fantastic sunroom thanks to Great Lake Windows. Not only does it look great and adds value to our home, but it also save us on heating bills. We are still waiting on the bottom windows to be custom made, but even without them, the solar energy that comes in through the windows heats the sunroom up to 80 during the day. All the windows pop out in the summer so we can enjoy the summer breeze as well.
