Flintlastic® Base 20 T

Overview
CertainTeed's Flintlastic® Base 20 T is a robust torch-applied SBS-modified bitumen base sheet, delivering the benefits of a homogenous roof system when paired with SBS-modified bitumen cap sheets such as Flintlastic® GTS-FR. 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.

This 120 mil base sheet is manufactured with a heavy duty, dimensionally stable fiberglass reinforcement that is highly resistant to tearing and punctures. The fiberglass mat is saturated and coated with an SBS-modified asphalt blend with elastic, waterproofing and fire-resistant properties. Flintlastic® Base 20 T is torch-applied, mitigating roof penetrations and allowing for extended warranty durations.
