Duramax is a water-resistant wall and ceiling panel that is used for wet environments, cleanrooms, and areas that require hygiene. As an affordable alternative to Fiber Reinforced Plastic (FRP) panels, it eliminates the need for Oriented String Board (OSB) backing panels. No time-consuming and messy gluing, no need for a second person to help with handling, and no need to ever replace the panels. Duramax panels require half the labor cost and half the material, giving you a competitive edge.
