Tri-Flex 15 is a synthetic roofing underlayment coated with polypropylene on both sides and offers many benefits to traditional #15 felt. This proprietary resin formula is used in the walk and deckside surfaces to create a slip resistant surface. It is 10x stronger than the #15 felt and prevents blow offs and tears in windy conditions. A 10 square roll is 67 percent lighter than #15 felt, and covers 2.3 times the area. This sustainable product is 100% recyclable and contributes to sustainability and LEED. It exceeds the requirements of ASTM D226 type 1 and II.

Tri-Flex 15 is used with asphalt shingles or most other roof coverings as a secondary watershedding material. It may be exposed up to 60 days and can be used alone or in combination with Grace self adhered underlayments.
