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.
In independent test2 results of ½” roof board, DensDeck® Prime Roof Board excelled:
In independent test2 results of ½” roof boards compared to DensDeck® Prime Roof Board:
When exposed to water all roof boards lose strength, including flexural strength, but to varying degrees. In independent test3 results of 1/2″ roof boards:
In independent test4 results of ½” roof boards compared to DensDeck® Prime Roof Board:
To varying degrees, exposure to freeze/thaw cycles have a compromising effect on the vertical pull strength of all roof boards, producing cracks and ruptures that continue to grow with time and lead to delamination. In vertical pull strength testing1 of 1/2″ roof boards after exposure to 21 freeze/thaw cycles, DensDeck® Prime Roof Board demonstrated:
