Exploring ways to insulate my EarthTainer as temperatures are getting hot. Has anyone tried rigid extruded or expanded polystyrene insulation boards? Can get 4' x 8' board (Rmax Plus-3 1/2 in. x 4 ft. x 8 ft. R-3.2 Polyisocyanurate Rigid Foam Insulation Board at Lowe's $12). Typically used in building construction. Easy to cut, doesn't hold water and won't mold or mildew. Can use on exterior. Cut into four pieces to surround EarthTainer. Then make simple shell to go around that (wood, cloth, bamboo, whatever) . Maybe only need 3 sides. Can make a number of these from one board. Might this work?
