<P>PROBLEM TO BE SOLVED: To provide a double-glazed glass which improves the external appearance of a building after construction because the head or the like of a bolt for fixing the double-glazed glass to a supporting member is not viewed since the glass disposed on the outer side of a room to constitute the outer side of the building is not bored, solves a problem of dew condensation on the supporting member used at the inner side of the room which occurs in the case that a bolt or the like penetrates through, and has the strength coping with a construction method where the supporting member is attached only to the inside glass sheet and the double-glazed glass is fixed by a cantilever support. <P>SOLUTION: A spacer is inserted into the inner side of a periphery of a plurality of glass sheets separated but facing each other, and a pair of glass sheets and the spacer are integrally bonded by using a thermosetting silicone rubber adhesive, as a primary sealing material, having bonding strength of ≥400 N/cm<SP>2</SP>measured by the shear bonding test according to JIS K6850. The periphery of the primary sealing material is sealed by a butyl rubber as a secondary sealing material and a concave part formed by a pair of glass sheets and the spacer at the periphery of the secondary sealing material is filled with a silicone sealant as a ternary sealing material. The double-glazed glass is thus formed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
