This wallpaper, made of coated fibre mat, can be used as a wallpaper
undercoat and is suitable for shielding large areas of walls and
ceilings against high frequency electromagnetic waves. The wallpapered
surface must be earthed, even if it is to protect against low-frequency
fields.
A perfect solution which is particularly used for bedrooms and
children's rooms. Even if the neighbours use, e.g., wireless LAN,
this is a very effective solution.
