Felts for Multiple-Ply Roofing Systems
Carlisles Type IV and Type VI Glass Ply Felts are saturated with asphalt, giving them excellent breaking strength and uniform porosity. Both felts meet ASTM D-2178 and may be used as an inner ply or base ply in a Carlisle multiple-ply system.
Carlisle’s Multiple-ply roofing systems combine traditional materials such as felts and base sheets with a unique AFX FleeceBACK cap sheet. These multiple-ply roof systems feature excellent puncture resistance and offer ENERGY STAR®-qualification without the need for coatings.
