Flintlastic® Ultra Poly SMS Base Sheet

Overview
CertainTeed's premium polyester-reinforced, smooth-surfaced, mop-applied, SBS-modified base sheet, Flintlastic Ultra Poly SMS, is both robust and resilient and delivers the benefits of a homogenous roof system when paired with SBS-modified bitumen cap sheets such as Flintlastic GMS, Flintlastic FR-P and Flintlastic Premium FR-P. Many members of the design and specification community prefer multi-layer modified bitumen roof systems constructed with the same polymer-modified material and application methodology for base and/or interply and cap sheets, to optimize stress resistance to the roof system with materials expanding and contracting at the same rate. Ultra Poly can also be torch-applied and, while most commonly utilized as a base ply or interply, may also serve as a cap membrane when coated with SMARTCOAT reflective roof coatings.

More polymerized asphalt and a heavier reinforcement than it's "younger brother", Flintlastic Poly SMS, this 145-mil membr
