<P>PROBLEM TO BE SOLVED: To provide multiple glass in which the generation of dew condensation at the inside can be prevented, and to provide a production method therefor. <P>SOLUTION: The multiple glass 1 mainly consists of two glass sheets 3 and 4, a ring spacer 2 made of aluminum charged with a drier 2a and incorporated into the space between the two glass sheets 3 and 4 so as to define a sealed space 9, a pair of primary seal materials 5 made of butyl rubber filled into the space between the ring spacer 2 and the glass sheet 3 and the space between the ring spacer 2 and the glass sheet 4, and a secondary seal material 6 made of polysulfide filled into the space between the glass sheets 3 and 4 at the outside of the ring spacer 2. The ring spacer 2 has projecting parts 20 along the longitudinal direction at the outside faces thereof, and is joined at a joint 7 by a connector. In the joint 7 in the ring spacer 2, the surface of the outside as for the glass sheets 3 and 4 is spray-coated with a moisture nonpermeable film 28 made of butyl rubber. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
