<p>The present invention relates to a vacuum insulation panel which can provide excellent insulation performance, have a simple structure, and be easily manufactured by forming vacuum therein. The vacuum insulation panel comprises: a core which has a structure where inner cells with a polyangular column shape are adjacent to one another; an upper plate which is attached to the top surface of the core, and includes penetrating holes at positions corresponding to the inner cells; a lower plate which is attached to the bottom surface of the core, and includes penetrating holes at positions corresponding to the inner cells; a vacuum forming envelope which covers the core, and the upper and lower plates from the outside when discharging gas inside the inner cells; and a flame retardant foaming agent which is formed by adsorbing to the surface of the vacuum forming envelope.</p> |
