Need help MT insulation

[popeiam]

I need to find a way to insolate my mashtun, I seem to lose a lot of heat during my mash and find myself heating it up. Until I can do a recirculation I was thinking the cheaper way to go would be to insolate it. I would like it to be some what resistant to heat but not direct heat from a burner. Any Ideas?

A lot of the guys including myself use Reflectix bubble foil type insulation. It's cheap and easy to cut to size. I would suggest making it two or three layers thick. The more the better. Make a cover for the lid too as a lot of heat is lost through the top of the MT:
