Safety glass.
But what is it actually?

VSG – standard laminated glass, mainly used in ordinary structures with a low safety rating.

VSG/ESG – laminated glass consisting of two sheets of tempered glass. It is used in railings, canopies, stair constructions, and glass floors. It offers high impact and scratch resistance.

VSG/TVG – this laminate can be constructed entirely of half-tempered glass or a combination of half-tempered and tempered glass. It is suitable for canopies, railings, and floors.

For enhanced security, additional inserts or steel mesh can be used. The color and translucency of the laminates can be customized.
