## Abstract

A thermal protection system for an ISO container includes roof panels attached to factory installed corner fittings on the container roof. The roof panels may be level or inclined and may include cavities for insulation. The standoff distance between the roof panels and the container roof is adjustable in certain embodiments. The roof panels may be layered to enhance thermal protection. Reflective coatings applied to the panels further enhance thermal protection from solar radiation.

## Claims

### Claim 1

A method of thermally protecting an ISO container having a roof comprising the steps of:
positioning a rigid roof panel above the roof of the ISO container thereby creating a standoff distance between the roof and the roof panel;
attaching the roof panel to at least one corner fitting on the roof of the container 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;
interlocking a plurality of roof panels to form a larger, composite roof panel;
adjusting the standoff distance between the roof and the roof panel; and
coating at least one surface of the roof panel with a highly reflective material.

### Claim 2 (depends on 1)

The method of claim 1 further comprising:
receiving solar energy to produce electrical power to drive a fan to force ambient air between the roof and roof panel.

### Claim 3 (depends on 1)

The method of claim 1 further comprising:
inserting thermal insulation material into at least one cavity within the roof panel.

### Claim 4

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.

### Claim 5 (depends on 4)

The thermally insulating roof panel of claim 4 whereby the lower surface is coated with a low emissivity material.

### Claim 6 (depends on 4)

The thermally insulating roof panel of claim 4 is comprised of material selected from the group including plastic, metal, fiber reinforced composite material, wood products and wood by-products, polymers, and recycled materials.

### Claim 7 (depends on 4)

The thermally insulating roof panel of claim 4 further comprising at least one solar panel on the upper surface to produce electrical power to drive a fan.
