PURPOSE: A thermal insulation panel is provided to offer a remarkably improved heat insulation effect. CONSTITUTION: Thermal insulation panels (100a) for agricultural facilities are formed of a synthetic material including PET material. A layer formed with at least five multilayered tunnel type spaces is installed on the first row and first layer of the thermal insulation panels, and the layer is sealed with covers (200a,300a). The multilayered tunnel type spaces have more than 3 layers. The multilayered tunnel type spaces include first tunnel type spaces (101a,101b,101c), second tunnel type spaces (102a,102b,102c), and third tunnel type spaces (103a,103b,103c). The tunnel type spaces are in the vacuum condition. |
