A thermal insulating element ( 10'; 10 ''') comprises a first plate ( 24 ) forming at least a part of an outer face of the insulating element ( 10'; 10 ''') and a second plate ( 26 ) forming a further part of the outer face of the insulating element ( 10'; 10 '''). The first and the second plate ( 24, 26 ) are connected to each other via a frame structure ( 12 ) which establishes a geometry of the insulating element ( 10'; 10 '''). The first and the second plate ( 24, 26 ) and the frame structure ( 12 ) define a cavity filled with air, wherein at least one vent opening ( 28 ) is formed in the first and/or the second plate ( 24, 26 ) and/or the frame structure ( 12 ). A projecting edge portion ( 34, 36 ) is formed along an edge of a portion of the insulating element ( 10'; 10 ''') which is provided with the at least one vent opening ( 28 ), the projecting edge portion ( 34, 36 ) being adapted to at least partially cover a gap between two insulating elements ( 10'; 10 ''') disposed side by side.
