Products / Owens Corning Titanium X30 Synthetic Underlayment

Titanium X30 is a synthetic underlayment with Comfort Grip cushioned, anti-slip walking surface, for use under asphalt, metal, mechanically attached tile and composite shingles, with up to six months of UV exposure; Owens Corning says it can be anchored with staples up to three days before the asphalt roofing goes on. The roll is 143 ft. x 42 in. (5 squares) and weighs 26 lbs.; the brochure and page print the metric roll area as 93 m2, which does not match a 5-square roll. Its ASTM E108 Class A fire resistance applies when installed under asphalt shingles.
