Patent ID: 8780314

Claim:
A strengthened structural module comprising an essentially planar glass substrate, an essentially planar second substrate, and at least one spacer element in between the essentially planar glass substrate and the essentially planar second substrate and in contact with a planar surface of the essentially planar glass substrate and a planar surface of the essentially planar second substrate, the at least one spacer element keeping the essentially planar glass substrate and the essentially planar second substrate separated from each other from edges of the essentially planar glass substrate and the essentially planar second substrate, the at least one spacer element defining a space in between the essentially planar glass substrate and the essentially planar second substrate in an inside of the strengthened structural module, wherein the strengthened structural module comprises a coating having a thickness of less than 50 nanometers, the coating surrounding the strengthened structural module around an outside of the strengthened structural module, the coating being arranged conformally on the essentially planar glass substrate, on the essentially planar second substrate, on the at least one spacer element, and on surfaces facing the outside of the strengthened structural module, for increasing strength of the strengthened structural module.
