Grace Construction Products, Cambridge, Mass., announces the addition of its patented ripcord into the release liner of Grace Ice & Water Shield self-adhered roofing underlayment. Designed to ease positioning and installation of the underlayment, the ripcord is embedded under the release liner. When pulled, the cord splits the release liner into two separate pieces. This new enhancement allows contractors the option of either splitting the release sheet for easy positioning and installation or removing the release sheet in one piece.
