FIELD: construction industry.
SUBSTANCE: invention refers to construction industry, and namely to heat-insulating constructions. Heat-insulating block element consists of internal air-proof shell made from flexible material, and external air-permeable shell that protects internal shell from damage. External element shell has areas where it is firmly connected with internal shell as well as areas wherein there is no firm connection of external and internal shells. External shell is made, fully or partially, from air-permeable material at the location of latter areas; total external surface of internal shell equals or exceeds total internal surface of external shell. Internal cavity of air-proof shell is filled with gas and/or heat-insulating material capable of reversible deformation. Method of manufacturing heat-insulating enclosure from heat-insulating block elements is described.
EFFECT: reducing material consumption, improving enclosure heat-insulating characteristics, and providing possibility to produce heat-insulating enclosure of any configuration.
