Abstract
TPO and PVC building membranes are disclosed that comprise RFID tags that are capable of storing identifying information. The RFID tags may be embedded in the membranes. By appropriate positioning of the RFID tags in the core layer of the TPO and PVC membranes, the properties of the membranes such as waterproofness and strength are not degraded by the presence of the tags and the functionality of the tags is not compromised by the manufacturing process. A method of manufacturing the membranes is also disclosed.
