Glass sandblasting

Glass sandblasting (also known as matting) is a mechanical process in which the surface of glass is roughened using a high pressure jet of sand. The abrasive material, i.e. sand, removes the outer surface of glass, which results in visible matting.

This technology lets us produce subtle effects: we can make any pattern, either transparent on a mat pane or the other way round: matted on a smooth pane.

Sandblasting is divided into:

  • sandblasting of the entire surface

  • segment sandblasting

  • pattern matting

Dubiel Vitrum has its own patterns, ready to be used in the production of, e.g. sanded glass doors or mirrors. Per individual request, we can also design special patterns.

Sanded glass is used in a wide range of applications. It is most often used in such projects as:

  • glass doors

  • partition walls, glassed-in elements, and built-in structures

  • glass shelves

  • mirrors

  • balustrades

  • glass interior furnishing elements

At Dubiel Vitrum, glass is sanded in an NC-controlled automatic sandblasting machine or manually.
