ATLANTA – Georgia-Pacific Gypsum unveiled the latest development in its ongoing 30-year tradition of market-driven innovation at IRE 2018: DensDeck® Prime Roof Board with EONIC™ Technology. Designed for enhanced water resistance and increased vertical pull strength, DensDeck® Prime Roof Boards with EONIC™ Technology are a significant leap forward. They are the only roof boards with manufacturing specifications that include a surface water absorption rate of 1 gram, and a total water absorption rate of 5 percent.

“This innovation is redefining what moisture resistance means in roof boards,” said Mikael Kuronen, Director of Product Management & Marketing for Georgia-Pacific Gypsum. “The addition of EONIC™ Technology is enabling outstanding results for DensDeck® Prime in Total Water and Surface Water Absorption tests as well as Vertical Pull Strength.”

In independent testing of Total Water Absorption2, alternative coated glass mat gypsum roof boards absorbed 76 percent more water more water than ½” DensDeck® Prime Roof Boards with EONIC™ Technology, while ½” gypsum fiber boards absorbed 132 percent. In independent testing of Surface Water Absorption3, ½” gypsum fiber absorbed 2.3 times more water than DensDeck® Prime Roof Boards with EONIC™ Technology, while alternative coated glass mat gypsum roof boards absorbed 4 times more water. Finally, in vertical pull strength4 tests, DensDeck® Prime Roof Boards with EONIC™ Technology were found to be 74 percent stronger than ½” gypsum fiber boards on the face, and 14 percent stronger on the back. When compared to alternative coated glass mat gypsum boards, DensDeck® Prime Roof Board is even more impressive, with 2.5 times greater strength on the face, and 7 times more strength on the back.
