Energy Efficient and Environmentally Sound: Each layer of Flexible DASH Adhesive expands to 1 ⁄16"–1 ⁄8"-thick and provides an additional R-value of 0.20 to 0.50 per layer. The NRCA estimates that up to 10% of R-value can be lost due to joints in the insulation. The expanding nature of DASH adhesive helps to seal insulation joints, when Flexible DASH Adhesive is specified for insulation attachment in place of mechanical fasteners, the 3–8% loss in R-value can be eliminated.

Water is used as the blowing agent in Flexible DASH Adhesive, making it VOC compliant and not labeled as a flammable product. Superior wind uplift resistance is delivered with uplift pressures ranging from 90–945 psf depending on the substrate. Due to its superior wind uplift performance, the Flexible DASH Adhesive System can qualify for upgraded wind speed warranties 80–120 mph with design enhancements.

Expedient Installations without Interruption Due to the low noise and low odor associated with the system, make the Flexible DASH assembly an excellent choice for re-roofing occupied buildings, as there is minimal disruption. Because of these benefits, schools, universities and hospitals are some of the biggest users of the Flexible DASH assembly. The speed of application with Flexible DASH Adhesive affords project completion in a timely manner.

Flexible DASH offers a significant reduction in free MDI: from 32% to 23% compared to traditional urethane adhesives.
