<p>The invention relates to a multiple window glass comprising a first laminated glass plate and a second simple or laminated glass plate, parallel to the first and separated from it by a gas layer, the two plates being held together in a gastight manner. The resin of the laminated glass of the first plate (1) is chosen so that a bar 9 cm long and 3 cm wide, consisting of a laminated glass comprising two glass sheets 4 mm thick joined by a 2 mm layer of this resin, has a critical frequency that differs at most 35% from that of a glass bar having the same length, same width and 4 mm thickness.</p> |
