Abstract:
1. A method of making a shielding material, comprising the actions of: (a) extruding a vapor barrier film onto a non-conductive sheet so that a portion of the vapor barrier film extends beyond the non-conductive sheet; (b) applying an elongated adhesive strip onto the vapor barrier film adjacent to a first edge thereof, the elongated adhesive strip including a removable cover film that protects the elongated adhesive strip until the cover film has been removed; (c) applying an adhesive layer to a side of the non-conductive sheet that is opposite the vapor barrier film; and (d) applying a conductive sheet to the adhesive layer so that a first portion of the conductive sheet extends beyond the non-conductive sheet and so that a second portion of the non-conductive sheet, disposed oppositely from the first portion, extends beyond the conductive sheet.
