THE INSULATOR AND THE SAME METHOD

摘要

Provided is an insulation body (1150) capable of fundamentally preventing a heat reflection film from being contaminated due to external air and including excellent insulation properties by being formed with a plurality of spherical insulation unit bodies (250). The insulation unit body (250) is formed in an assembly of the insulation unit body including a spherical film member (110) including a sealed space unit inside and a partial heat reflection film (120) formed in a dome shape at a part of the inner surface of the film member. Argon gas is injected into the inner space of the insulation unit body.
