<p>A condensation preventing structure forming a space and a condensation preventing steel door provided at an entrance/exit for an indoor space. An object of the present invention is to provide a condensation preventing structure having a performance close to an organic heat insulating material as a heat insulating performance, having a performance of the conventional inorganic heat insulating material in terms of flame resistance, and conditioning humidity in the space to a comfortable level by forming a heat insulating layer having moisture absorbing and releasing properties, to thereby form a space that can reliably prevent the occurrence of condensation, and to provide a condensation preventing steel door capable of reliably preventing the occurrence of condensation. The present invention uses a heat insulating material wherein the 3-50 parts wt. equivalence of a synthetic emulsion solid, 1-20 parts wt. of organic micro-balloons, 3-5 parts wt. of carbon fibers and 10-200 parts wt. of inorganic micro-balloons are mixed with 100 parts wt. of cement.</p> |
