OPALFILM Shielding

OPALFILM® shielding films are window retrofitting films that block the transmission of electronic data sent wirelessly and openly from laptops, mobile phones, cordless phones, and other devices, thereby significantly preventing such signals from passing through glass panels from the inside of a building to the outside. At the same time, the film protects people, for example in residential homes, from hazardous electromagnetic radiation entering from the outside. As a beneficial side effect, OPALFILM® shielding films also provide protection against heat, glare, and UV radiation.
