From DensDeck® Roof Board to DensDeck® Prime Roof Boards with EONIC™ Technology, a dedication to advancement continues to bring new innovations to a product line with a noble history. DensDeck® StormX™ Prime Roof Board builds on that legacy by innovating on impact resistance and strength.

As weather events intensify across the United States, our building roof system design approach and material installation must adapt too. DensDeck StormX Roof Boards help prepare commercial rooftops to hold tough under today’s severe weather conditions. Specify DensDeck StormX cover boards in any situation where you need enhanced impact resistance, but always specify it in very severe hail zones.

When warmer climate leads to atmospheric instability and thunderstorms, a single extreme hailstorm can leave hundreds of thousands of dollars in damage and put you out of business for good. But including a high-performance cover board in your roof assembly can help defend against common damage like dents, cracking, crazing (webbed circular microfractures), and compound delamination which exposes the membrane reinforcement. With larger, more intense hailstorms comes greater commercial roofing damage and deeper financial losses. DensDeck StormX cover boards help ensure you’ve built in the strongest defense to weather the storm.
