What is the difference between NobleSeal TS and NobleSeal CIS?
A. TS was initially developed as a product for thin-set waterproofing. The sheet is a composite made from CPE with non-woven fiber laminated to both sides. There is a two-inch [2″] bare edge on the bottom of one side of the sheet and the top of the other side. This area of bare CPE membrane was is for joining [seaming] sheets together. TS is .030″ thick and comes on rolls 5′ X 100′. CIS was designed for crack isolation. It is also a composite and is made from CPE with polyester fiber laminated to both sides. However, CIS does not have a bare edge and fiber covers both sides of the membrane. CIS is also .030″ thick and comes in 4 different widths [2′, 3′, 4′ and 6′]. All CIS rolls are 50′ long.
