<p><P>PROBLEM TO BE SOLVED: To provide multiple-layer glass which has a structure which makes the glass itself communicate with the open air, the structure preventing the glass itself from being deformed into concave/convex shapes due to the changes of the peripheral temperature and atmospheric pressure of the environment, in which the glass concerned is used, to maintain its dew point for a long period of time. <P>SOLUTION: In a multiple-layer glass panel, a moisture adsorbing/releasing material 6b which is charged into a spacer 2', to which a ventilator 8 comprising a hollow tube which communicates with the open air is connected, is different from a moisture adsorbing/releasing material 6a which is charged into the other spacers 2. The moisture-adsorbing capabilities of these moisture adsorbing/releasing materials are regenerated by optimally selecting moisture adsorbing/releasing materials when the temperature in the hollow layer of the multiple-layer glass rises due to the rise of atmospheric temperature or heating by sunshine, and consequently the dew point in the hollow layer is not worsened for a long period of time. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
