Abstract

The present invention relates to a vacuum insulation panel (1) having a core (5) having insulating hollow spaces and cover layers (11) closing off the core (5) from the environment, the hollow spaces of the core (5) being formed by two chambers (3) sealed off from each other in a gas-tight fashion, extending together with the walls (4) or intermediate walls thereof from one cover layer (11) to the other cover layer (11) and being formed from the walls (4) or intermediate walls and the cover layers (11). The present invention further relates to a method for producing such a vacuum insulation panel (1), wherein a) plates (7) are produced having the shape and arrangement in cross section of walls (4) of the half chamber (3) connecting to each other, but being substantially longer than the height of the walls (4) of the chambers (3), then b) a composite (9) then being produced, in that a further such plate (7) is laid on a first such plate (7) such that the entire chambers (3) are formed, c) the plates (7) are then connected to each other, in a gas-tight and permanent fashion, at the contact points (8) thereof, d) further plates (7) are then laid on the uppermost plate (7) of the composite (9) according to step b) and connected, in a gas-tight and permanent fashion, to the uppermost plate (7) of the composite (9) according to step c), e) the composite (9) is further cut transverse to the plates (7) into chamber discs (17) having the desired thickness corresponding to the intended chamber height, and f) the chamber discs (17) are connected, in a gas-tight and permanent fashion, to the cover layers (11) on the open sides of the chambers (3).
