THERMAL STORAGE SHEET FOR BUILDING FINISH MEMBER, AND THERMAL STORAGE BUILDING FINISH MEMBER

摘要

PROBLEM TO BE SOLVED: To impart thermal storage property and thermal insulation property and to make it difficult to transfer outdoor low temperature to the inside by using a thermal storage sheet for a building finish member which is obtained by laminating a thermal insulating layer on a thermal storage layer which has a thermal storage material dispersed in a polymer matrix. ;SOLUTION: A thermal storage sheet 10 for a building finish member includes a thermal storage layer 11 obtained by dispersing a thermal storage material in a polymer matrix. The thermal storage sheet 10 for the building finish member has a thermal insulating layer 12 such as a foamed layer laminated thereon, and prevents emission of heat stored by the thermal storage layer 11. Further, a moisture permeable sheet is laminated on the thermal storage sheet 10, and therefore it suppresses moisture permeation to the adjacent thermal storage layer 11 and the thermal insulating layer 12, to thereby prevent degradation of the thermal insulation property. The thermal storage sheet 10 is used as a laminated sheet such as one stuck to the surface of the building finish member, and therefore it is preferably decorated. The thermal storage sheet 10 has the thermal storage material dispersed therein, and therefore it stores heat at elevated temperatures and emits heat at lowered temperatures. As a result, transfer of outdoor low temperature to the interior of a room can be temporarily alleviated.;COPYRIGHT: (C)2000,JPO
