This graph is a guide to the typical shielding effectiveness of EmiClare mesh.
EmiClare Sigma windows are CNC machined to size with either a stepped or square edge profile. A silver painted bus bar is used to terminate the mesh in a "L' or 'C' shape cross section, this has 5-10 db reduction in shielding compared with direct contact to the mesh. Windows can be supplied with additional conductive gaskets, environmental seals and tapes.
