Methods and systems for constructing or retrofitting electromagnetically shielded facilities
Electromagnetically shielding an enclosable structure having a floor, walls, a ceiling, and at least one closeable opening by applying a shielding wallcovering to at least a portion of one of the walls and applying a second type of shielding material to at least a portion of the enclosable structure, wherein the second type of shielding material differs from the shielding wallcovering. The shielding wall covering is wallpaper comprising a metal-coated broad good and a resin. Other types of shielding material may include a transparent, shielding window covering such as NiCVD coated screen of woven silk fibers; shielded flooring such as a layered combinations of Kevlar non-woven as a base layer, nickel-coated non-woven layers, and a PCF toughened polymer; and a transition shielding strip made of a base layer of the shielding wallpaper with a PCF toughened polymer coating over a portion of the strip.
