Spec Sheet Super Duct is Johns Manville Premium Duct Board with such features as a coated surface on the airstream vs. the black mat seen on standard duct board. This gives it a more durable air surface that serves as anti-microbial and ensures that no fibers are in the airstream, with better water repellency. Also allows it to withstand better air velocity at 6000 fpm, vs. 5000 fpm with standard duct board.
