Since 1969, architects and owners have looked to Dryvit for excellence in EIFS. For over 35 years, the barrier style, Class PB, Outsulation System has remained essentially as originally designed and has been installed on over 350,000 buildings worldwide. Today, there is increased demand for a wall system to be able to drain away incidental moisture. Dryvit responds to this demand with Outsulation MD.
Moisture Drainage Technology
Outsulation MD offers the most comprehensive, easy-to-install drainage system available for commercial use today. It provides three lines of defense against water intrusion. The first is Dryvit's time-tested combination of reinforced base coat and finish. The second is our specially-designed, grooved EPS with drainage track and vent assembly.
The third is Backstop NT, an air and water-resistive barrier. A waterproof flashing material such as Dryvit AquaFlash System or flashing tape is also used to protect sills of wall openings (such as windows). A compatible sealant must be utilized at all system terminations.
