Figured I would get some questions on the insulation..
It is 2-Layer..
The first layer is a high density foam yoga mat from Wally World.. Trimmed the width to 2" less than the height of the keg.. Those mats came with some elastic bands to hold the mat in a rolled condition for storage, used a little spray adhesive and the elastic bands, and some aluminum tape to hold the mat in place.
The second layer is reflectix from lowes.. The top folds over really nicely for a "tuck-and-roll" appearance..
The bottoms are also insulated using a similar method.. HLT is electric with a 5500w heating element..
