<p>The present invention relates to a sandwich panel comprising a phenolic resin cured foam and to a production method therefor, and, more specifically, relates to technology for providing an outstandingly reliable sandwich panel by using a phenolic resin cured foam to form a core layer between non-combustible plate materials on the front surface and the back surface, thereby imparting a high level of thermal insulation performance, with a thermal conductivity of no more than 0.02 W/mK, and at the same time resolving the problem of corrosion at the surfaces adhering to the plate materials.</p> |
