Q1: Given its excellent performance, why is vacuum glass often required to be laminated or used as a composite? Can it be used as a standalone unit? In what scenarios is lamination mandatory?

A: According to current national standard requirements:

Curtain Walls: Vacuum glass should not be used as a standalone unit; it is recommended to be used as a vacuum-insulated composite or laminated unit.

Windows and Doors: There are no such standard restrictions; therefore, vacuum glass can be used as a standalone unit.

International Perspective: There are no such restrictions abroad, and many international projects directly utilise monolithic vacuum glass.
