FIELD: construction. ^ SUBSTANCE: invention is related to construction industry, namely to heat insulating devices for barrier structures. Heat insulation device of barrier structures contains cavity. Device comprises body made of steel sheets joined by welding seam, with provision of cavity, inside of which there is net arranged for elimination of sheet walls contact with each other. Aside, in area of sheets connection, there is tube welded in to pump air out and develop underpressure inside device, to increase coefficient of heat transfer resistance, and with further closure of its opening. ^ EFFECT: improved thermal parametres, quick installation, duration of operation. ^ 2 dwg |
