Facing and Insulating the Steel Shipping Container

David Cross from TAW shows Bob how the exterior is finished with heavy-gauge steel to bring any voids out to plane. It is then faced in a sheet-metal wrap to give it a smooth, uniform surface on the exterior. Bob remarks that this is much like an oven, set to bake in the Florida sun. Cross shows Bob how effective the SuperTherm insulative ceramic coating is at stopping heat transfer as he places a blow torch on one side, then touches the other side, which is cool and protected by the SuperTherm barrier. This coating has four different ceramics to help deflect energy from the sun and send it back to the source. Cross explains that just one coat of SuperTherm, sprayed on at 16 mils thick and dried to 10 mils, has the insulation equivalent of R 20, which is enough to keep this house cool and energy efficient in a hot climate.
