DEW CONDENSATION-PROOF SHEET

摘要

PROBLEM TO BE SOLVED: To provide a lightweight and compact dew condensation-proof sheet with such advantages that a great deal of electric power can be saved and surface dew condensation outside a chest can be prevented from occurring. SOLUTION: This dew condensation-proof sheet is a laminate of a composite structure comprising a surface layer, a heat shield layer and a back layer. In addition, the sheet is characterized in that the surface layer is constituted of a sheet-like material and the back layer of an air-permeable sheet-like material.
