PROBLEM TO BE SOLVED: To resolve an inconsistency that, in a glass wool heat insulation material which is an indispensable raw material for building, covered with a heat reflection aluminum foil for improving functionality thereof, both materials being noncombustible materials, a combustible resin adhesive is being used as an adhesive, resulting in a case of fire in melting and dissipation of the glass wool heat insulation material due to combustion of the adhesive.SOLUTION: Provided is an adhering medium containing a sodium silicate solution. The sodium silicate solution is a reaction product of silica sand and soda, has high heat resistance, can tolerate melting of the heat reflection aluminum foil in an exposed portion in a case of fire. The adhering medium is used as a non-inflammable heat-resistant adhesive applied by a high temperature-resistant closed cell lamination molding, can maintain heat-resistance of the glass wool heat insulation material without generating toxic gas in a case of fire, and is effective for maintaining an environment for human life. |
