Openings shield against electromagnetic waves electric pulses and/or electric rays, preferably for window openings of shielded enclosures

摘要

A screen against electromagnetic waves, electrical pulses and/or electrical radiation for openings, preferably window openings, of screened rooms consists of at least one conductive layer which is connected at the side to a conductive border of the opening. In order to produce the screening in an economical manner and to enable it to be handled in a simple manner so that it can be activated and installed quickly when required and subsequently can be removed again, so that the openings or windows can be freely seen through or passed through again, the border consists of a contact frame, which is conductively connected to the screen of the room, and can be compressed against the compression frame by means of a compression device. The compression frame is provided with a hanging or a sheet of screening material or with a screening coating. The compression frame can also press such a hanging or such a sheet in a conductive manner against the contact frame.
