Tri-Flex® 15

tri-flex 15TRI-FLEX® 15 is a new and improved mechanically-attached, synthetic, water-shedding underlayment that can be used as a standalone product or in conjunction with self-adhered underlayments such as Grace Ice & Water Shield® and Grace Select™ Roofing Underlayments. It is 100% recyclable, and contains post-industrial recycled polymers, contributing to sustainability and LEED.

In comparison to #15 Felt, TRI-FLEX® 15 underlayment is 10x stronger, preventing blow-offs and tears in windy conditions, and provides higher coverage per roll, with fewer laps and fasteners. TRI-FLEX® 15 membrane is also more slip resistant that #15 Felt and can be exposed for up to 60 days.

TRI-FLEX® 15 underlayment is suitable for use under asphalt shingles and most other major roof coverings.  This membrane is backed by a team of local technical support personnel that helps ensure every application goes smoothly.
