@smonteton My original thought was to help keep heat in during the mash by reducing the head space from the top of the mash to lid of the kettle...it worked okay. In my other photos, I also put more of the material around the kettle.
I was only mashing 1.5 gallon beer at the time.

thats pretty neat. If you can get this to work any better you'll definitely have to make another post on it.
