Thermal protection apparatus and method for ISO containers

A thermally insulating roof panel system comprising:

• a first and a second roof panel each comprising an upper surface, a lower surface, four edges, four corners, and at least one internal cavity;
• the upper surface is coated with a highly reflective material;
• insulation material may be inserted into the internal cavity to augment the thermal insulating properties of the panels;
• at least one edge of the first roof panel comprises an interlocking pattern to mate with the edge of a second roof panel to form a larger, co-planar, composite roof panel;
• attached to near at least one corner of the composite roof panel is a roof panel anchor to removably attach the composite roof panel to an ISO container to be thermally protected having a roof and at least one permanently installed corner fitting comprising a rectangular box with top and side openings to receive a complementary anchor having engaging portions to mate with the side openings of the corner fitting whereby the composite roof panel is positioned above the roof of the ISO container;
• a standoff distance is maintained between the ISO container roof and the composite roof pane;
• and
• at least one roof panel anchor receptacle fixed to the upper surface of at least one of the first or second roof panels comprising the composite roof panel to removably engage a complementary anchor attached to a bottom surface of a third roof panel positioned above the composite roof panel.
