FIELD: building, particularly production of articles having high heat-insulation properties.
SUBSTANCE: method involves assembling article pack, forming cavity in the pack and evacuating the cavity. Pack is formed by pressing plates one to another. Then the pack is laid on support, which touches pack perimeter. One plate is carried to condition, which provides plastic deformation thereof under the action of three-dimensional forces to be applied to the plate. The cavity is formed and the cavity is evacuated simultaneously by above three-dimensional force application. Before cavity is formed the pack is sealed along plate contact area. The three-dimensional forces are inertia force, magnetic force or gravity force. The cavity may be also created by applying vacuum to the pack from side of plate carried to condition, which provides plastic deformation thereof under the action of three-dimensional forces.
EFFECT: reduced labor inputs and improved technical and service properties.
