In this embodiment, the moisture-absorbing layer 103 is generally a water-absorbing resin wrapped by an elastic breathable material, which absorbs moisture in the air while maintaining its shape to achieve the purpose of dehumidification, and the water-blocking layer 102 can be a completely non-water-absorbing material such as a metal plate to prevent the water vapor in the moisture-absorbing layer 103 from penetrating into the surface of the heat preservation substrate 101 and hindering the heat preservation work.

[0025] The outer edge of the insulation substrate 101 is provided with a plurality of fixed bolts 301, each fixed bolt 301 penetrates the insulation substrate 101, and both ends of all the fixed bolts 301 are respectively sleeved with a protective outer panel 201, and each protective outer panel 201 is provided with a connecting fence 204 on the side away from the insulation substrate 101, and each connecting fence 204 is sleeved with the corresponding side of the plurality of fixed bolts 301, and the outer edge of each protective outer panel 201 is in contact with another protective outer panel 201, and the outer edge of each connecting fence 204 extends to the outer side of the adjacent protective outer panel 201. The outer sides of the two protective outer panels 201 can be provided with a side railing 203, and the outer edge of each side railing 203 is flush with the outer edge of the corresponding protective outer panel 201. In this embodiment, both ends of each fixed bolt 301 are provided with a fixed bolt sleeve 202 to assemble the insulation board. When multiple insulation panels are arranged in an array, the protective outer panel 201 in the middle of the array can be surrounded by the connecting railings 204 on all sides, while the protective outer panel 201 at the edge is flush with the connecting railings 204 on the outer surface through the side railings 203, and the outer edge is flush with the edge of the wall where the insulation panel is installed, which is convenient for installation.

At the same time, by setting the connecting railing 204, the seam formed between the two adjacent protective outer panels 201 is blocked, so that the seam contour between the two adjacent protective outer panels 201 becomes tortuous, making it difficult for the air on both sides of the insulation panel to exchange, thereby improving the insulation effect to a certain extent.
