• Murals and decals: Cover sections of your windows with decals and murals printed with your pictures, logo, lettering and other design elements. Mesh decals allow light to come through while adding privacy for the interior.
• Finishes: Transform glass itself into a pattern via glass finishes. Add a coarse-grained finish in the shape of waves, vertical lines, or other geometric patterns to incorporate a unique mathematical look and protect privacy for what goes on behind the windows.
• Sandblasting: Coarse particles such as fine sand are blasted onto glass planes to create a texture. Create ridges, waves and lines in glass or smooth sections of textured glass.
• Etching: A classic treatment using acids or other corrosive substances to produce visual designs in glass. Create a frosted pattern on clear panes of glass or add a translucent pattern to satin or frosted glass.

And to expound further on those types of glass we can define some more types of privacy glass:

• Frosted Glass: Fabricated to hold a matted foggy appearance to veil and obscure, rather than block views entirely. Generally created using a film, acid etching, or via the use of sandblasting.
• Tinted Glass: Made of screens and panels chemically treated to alter the base color. The density and shade of the glass are changed depending on the level of tint, this adds benefits such as climate control and UV-Ray protection. Tinted glass color does not change or fade.
• Reflective Glass: Also known as mirrored glass, has a thin layer of metal infused onto one side and sealed with a clear protective coat. This is how traditional one-way mirrors are made for fun-houses and police interrogation rooms. As reflective glass carries a highly metallic gloss, its clear light and image refraction qualities cannot be understated.
• Satin glass: One of the most popular privacy glass types, satin, is pearlescent and clean while still holding a highly evenly dispersed opacity. Satin glass is created by combining hydrofluoric acid with a glass sheet. This type of privacy glass results in high opacity and an elegant appearance and features a matte sheen instead of a glossy one, thus the silky smooth look that gave it the name satin.
