<P>PROBLEM TO BE SOLVED: To provide sound-insulating multiple glass which provides a thin and lightweight sash satisfying the sound insulation class T-4 according to JIS A4706:2000 without using a double sash or sashes in layers. <P>SOLUTION: The sound-insulating multiple glass is constituted of laminated glass G' having a couple of glass plates G1, G2 constituting the multiple glass and a resin interlayer 1, and a single plate glass G. Helium is enclosed in a hollow layer 2, and the single plate glass G is thinner than the laminated glass G'. The thickness of the single plate glass G is 3.7-7.4 mm, and the thickness of the glass part of the laminated glass G' is 7.4-11.6 mm. The thickness of the resin intermediate layer 1 is 0.3-1.6 mm, and the thickness of the hollow layer 2 is 4.0-6.0 mm. Thereby, the thickness of the multiple glass being the sum of these thicknesses is 15.4-26.6 mm. <P>COPYRIGHT: (C)2009,JPO&INPIT |
