AI Technical Summary
Multilayer glass units with multiple glass plates improve heat insulation, sound insulation, and condensation prevention but increase weight, posing a challenge in balancing performance and weight.
A multilayer glass unit design featuring two outer glass plates and an inner glass plate, with spacers and a sealing member having a concave upper surface, where the inner glass plate is thinner and composed of boroaluminosilicate glass, offset from the outer plates, and the sealing member is embedded between them, enhancing durability and reducing weight.
The design achieves improved durability and reduced weight while maintaining or enhancing insulation and light transmittance, with the inner glass plate's lower solar absorption and higher transmittance contributing to reduced thermal stress and lower weight.
