Heat-insulating wall

Thermally insulating wall, such as a refrigerator door, cooler housing or similar device, with an outer coating substantially vacuum-tight which together with a membrane connecting the vacuum-tight, which is fixed at its free edges and formed material apparatus poor thermal conductivity, and an inner lining, which is connected sealingly to the vacuum in its free with the membrane connecting edges, enclosing a fill material evacuable support evacuable cavity, wherein the membrane connection is covered with a cover membrane formed of a material with poor thermal conductivity, characterized in that a protective profile member (20, 50) secured to the innerliner (15) and / or the outer lining (16) and arranged in a magnetic antipole (55) or a magnetic closure ( 42) it is mounted on the front of the membrane cover (19) to cover it.
