Method for joint construction of electromagnetic shielding flexible sheet

A method for constructing a joint between thin flexible sheets of electromagnetic shielding material, comprising:

• adhering first sides of multiple first sheets of shielding material to a wall;
• and
• adhering first sides of multiple second sheets of shielding material to second sides of the multiple first sheets of shielding material,
• wherein:
• a conductive adhesive or a conductive double-sided adhesive tape is applied to the first side of each of the first sheets of shielding material and the second sheets of shielding material,
• the first sheets of shielding material are arranged in a row, each first sheet overlapping a portion of an adjacent first sheet along at least one first seam, and
• the second sheets of shielding material are arranged in a row, each second sheet overlapping a portion of an adjacent second sheet along at least one second seam,
• further comprising:
• removing a non-conductive or weakly conductive coating from the second sides of the first sheets of shielding material before adhering the first sides of the multiple second sheets of shielding material,
• wherein the non-conductive or weakly conductive coating is a protective film or a foreign substance,
• further comprising:
• preprocessing a corner of walls by adhering a single sheet of third shielding material thereto before adhering the first sides of the multiple first sheets of shielding material to the wall;
• and
• postprocessing the corner of the walls by adhering a single sheet of fourth shielding material thereto after adhering the first sides of the multiple second sheets of shielding material,
• wherein the third shielding material and the fourth shielding material are made of the same material as the first shielding material and the second shielding material.
