PURPOSE: To obtain double layer glass which is mountable at a sash and does not require spacers by sealing a glass plate having a flange part and another glass plate via an adhesive over the entire periphery of the flange part, thereby forming a closed space. CONSTITUTION: The glass plate 2 having a flat part 2a, a continuous sidewall part 2b bent to have a recessed shape from this flat part 2a and the continuous flange part 2c bent outward from this sidewall part 2b is formed. This glass plate 2 and another glass plate 3 are then joined and sealed by the adhesive 4 over the entire periphery of the flange part 2c, by which the hermetically closed space 5 is formed between the glass plate 2 and the glass plate 3 and the double layer glass 1 is produced. The thickness of the sidewall part 2b of the glass plate 2 is preferably set at >=0.7 times the thickness of the flat part 2a. Low melting glass solder or low moisture vapor permeation resin adhesives are adequately used as the adhesive 4. The deformation of the glass plates 2, 3 is effectively prevented if dry air of ordinary temp., etc., are enclosed into the hermetically closed space 5. |
