In keeping with our tradition of market-driven innovation, Georgia-Pacific Gypsum has improved DensDeck® Prime Roof Boards with EONIC™ Technology, a patent protected enhancement. Incorporating EONIC™ Technology has doubled DensDeck Prime's resistance to moisture making it the only roof board with manufacturing specifications that include 5% total water absorption resistance by weight and 1 gram surface water absorption performance on both sides of the board1. But that's just the beginning of the story.
