The present invention relates to a sandwich panel for special vehicles, and more particularly, is to provide a sandwich panel for a refrigerated vehicle, capable of minimizing a defect rate by preventing lifting caused by bubbles, and maximizing the heat insulation efficiency by hermetically preventing leakage of cold air and inflow of external air through a gap formed in a joint. In the present invention, disclosed is a sandwich panel comprising: a core material made of any one selected from a foamed polyethylene, a foamed polyurethane foam, a foamed polystyrene foam, and an excluded polystyrene foam; a face sheet bonded to both sides of the core material by a thermosetting adhesive; and a fiber glass net bonded between the core material and the face sheet. The fiber glass net has a warp density of 9-9.5 strands per inch, a weft density of 8.8-9.2 strands per inch, and a thickness of 65-75 g/m^2. |
