TITANIUM-UDLTM is a super lightweight underlayment that is six times stronger than 30# felt. There is no wrinkling or buckling. Advanced, engineered resins provide dual-surface anti-skid properties and can handle six-month UV exposure. The gray color provides reflectivity and a cooler roof. The efficient 48-inch-by-250-foot roll saves time and money. The product comes with a 25-year limited warranty and is designed for use under tile, metal, shake and composition shingle. It complies with ICBO, BOCA, SBCCI, and Dade County.
