Frosted glass film is an easy to apply window film that provides privacy by giving glass the appearance of acid-etched or sand blasted glazing – preventing vision from both sides of the window.

The term opaque originated from the Latin, meaning 'dark' meaning 'not transparent' and opaque substance does not let any light pass through at all. A paint that is opaque will give a solid colour. Blacks and whites are always opaque and any colour mixed with them will become more opaque.
