An air pad for heat insulation according to the present invention has an excellent heat insulation property as a two-layered fabric contains air therein. Accordingly, the present invention can be used for the manufacture of products, such as a heat insulation material, an air mat, an air bed, a floating cover, and others and can simplify a manufacturing process of the products. The air pad for heat insulation comprises: expansion parts (10) formed of an upper fabric layer (11) and a lower fabric layer (13) separated from each other, and expanded by compressed air flowing into spaces (15) between the upper fabric layer (11) and the lower fabric layer (13); non-expansion parts (20) continuously formed from the expansion parts (10) between the expansion parts while having a single layer; and coating layers formed between the expansion layers (10) and the non-expansion layers (20) to prevent the outflow of the compressed air from the spaces (15) to the outside. |
