The present invention relates to a vacuum insulation panel (1) comprising a core material (2) with open porous structure and a barrier (3) that holds the core material (2) together. The open porous core material (2) is filled into a barrier (3) preferably together with a getter material, depending on the material properties forming the core material (2) and vacuumed. Thus, a vacuum insulation panel (1) is realized comprising the open porous core material (2) having low thermal conductivity coefficient, with increased insulation effectiveness.
