Where large areas of an existing building require RF protection, architectural shielding provides a suitable shielding solution.
The shielding medium is usually either a thin foil sheet of copper or aluminium. Suitable alternatives such as steel, mesh or special fabrics may be used, depending on the application. To maximise space, particularly in a complex space, the shielding material is applied directly to the parent building. RF shielded doors and other components are designed to interface with the shielding and building construction.
To complete the shielding a range of accessories such as RF shielded doors, waveguide air vents, filters etc. are available.
Shielding effectiveness is dependent on the shielding medium and type of shielded doors used, but with care a 'mid range' level of RF shielding performance level can generally be achieved using architectural shielding.
