Hello hear are some pic's of my upgraded mash tun that i insulated with 2 parts liquid foam & a pine surround

The piece of blocked of copper is for my PTC probe from my controller.

I have only tested with water at 66 degrees & it dropped 1 degree after 80 minutes in frosty weather.I think when i mash it will be even better as the mash helps insulate itself. Cheers
