Foil - frosted glass
Frosted foil is designed to imitate frosted glass. Sand-blasted foil is glued onto glass or plexiglass. This foil is variously referred to as: frosted foil, frosted foil, sandblasted foil. Sand-blasted foil is also used as a curtain so that bystanders cannot see what or who is inside, but also let the light pass through and the room is bright during the day.
