（第１図）のものとに対して複数回づつ行い、夫々の試
験結果を、第９図及び第３図のグラフで示す。By measuring the degree of condensation in the inner space of the double glazing,
The high temperature and high humidity resistance test, in which the durability is lower as the condensation is more likely to occur, is performed a plurality of times for the conventional structure shown in FIG. 8 and the structure of the present invention (FIG. 1). The test results of are shown in the graphs of FIG. 9 and FIG.
つまり、第９図及び第３図から明らかなように、本発明
の構造の複層ガラスの方が、耐久性が低下しにくく、複
層ガラス内部空間内に水が浸入しにくい。That is, as is clear from FIG. 9 and FIG. 3, the double glazing having the structure of the present invention is less likely to have lower durability and water is less likely to enter the inner space of the double glazing.
従って、高温高湿の環境で使用しても、複層ガラス内に

ではないかと思われる。As shown in FIG. 5 and FIG. 6, the edge (7) has the edge (7) and the sealing material (3) arranged relative to each other in a state of being covered with only the primary sealant (3A). However, although the moisture impermeability is superior to that of the conventional one, it tends to be slightly inferior to the moisture permeability of the arrangement structure of FIG. After all, the adhesiveness between the secondary sealant (3B) and the metal thin film depends on the primary sealant (3A) and the metal thin film, or the metal thin film removing part (5) and the primary sealant (3A) or the secondary sealant (3
It is better than the adhesiveness with B), and it seems that it has increased moisture impermeability.
