For PVC tiles glue one copper strip in the middle of each tile row on the substrate, for PVC sheets one strip in the middle lengthwise beneath each sheet. Finally connect all parallel strips by installing a copperstrip in 90 degree crosswise, e.g. close to the end . Two crosswise installed strips are necessarry for rooms up to 40m², for bigger rooms proportionately more. They have to be long enough to allow the connection to ground potential by an electrician
