High-Performance Underlayment

Lighter and stronger than 30-lb. felt

Grace Tri-Flex 30 is a spunbonded polypropylene sandwiched between layers of UV-stabilized polypropylene that provides a slip-resistant roofing underlayment that won't tear away from nails in high winds, even when left exposed. According to the manufacturer, Tri-Flex can be left exposed for up to six months without drying out or rotting at high temperatures, or cracking and becoming brittle at low temperatures. Weighing only 30 pounds for a large, 10-square roll, Tri-Flex is much lighter than 30-lb. felt, making installation easier. Tri-Flex 30 must be attached to the roof deck with roofing nails or staples through 1-inch-diameter plastic or metal caps. It's critical that the deck surface is swept clean and dry and that the material is pulled taut, but not stretched, when applied. Suitable for both new construction and reroofing, Tri-Flex meets the International Building Code as well as Florida Building Code requirements for roof coverings in high-velocity hurricane zones.
