FIELD: household appliances. SUBSTANCE: method involves making heat- insulated space by installing two flasks in a spaced relation, one inside the other, attaching gas absorber to the surface of one flask directed into the space, vacuumizing the space with simultaneous heating and sealing. The gas absorber consists of at least two layers, one of which is made of a material with a relative magnetic permeability exceeding a unity. Heating is conducted at 150-170 C for 1-2 h. After sealing, the gas absorber is locally heated by induction method to its activation temperature. EFFECT: higher efficiency. 1 dwg
