PROBLEM TO BE SOLVED: To obtain a multiple glass aggregate excellent in sound proofing property and heat insulating property, capable of maintaining common rebate depth, by hermetically bonding glass plates laminated through a plastic sheet to a single glass plate through a void packed with a gas. SOLUTION: At least two glass plates 5 and 6 having 1-3.2mm thickness are laminated through a plastic film 6 having >=3.8mm thickness formed from a resin having a resonance frequency fc in 35% difference between a strip which comprises a glass plate obtained by laminating two glass plates having 4mm thickness with a resin of 2mm and has 9cm length and 3cm width and a first mode of a glass plate of a monolith having the same length, the same width and 4mm thickness to give a laminated glass 2. The laminated glass 2 is hermetically bonded to a glass plate 3 having 2.5-8.2mm thickness through a void 4 having 6-20mm thickness charged with a gas. |
