QuietBoard, from MP Global Products, is engineered to provide superior support for multiple types of flooring with great acoustic and waterproof benefits. With its dense construction, the product is designed to reduce impact noise while increasing floor stability and minimizing flex between planks to make floors solid and comfortable. QuietBoard’s ECOWICK system is specially designed for maintaining structural integrity when moisture vapors are present. The fibers allow for the board to hold up to five times its weight in moisture while maintaining its shape and functionality and encouraging constant air flow and breathability. The material allows for the concrete to breathe, protecting the overlying flooring from harmful moisture and inhibiting mold and mildew. The dense, recycled fiber structure of QuietBoard is designed to absorb high levels of both impact and ambient sound, minimizing unwanted walking and room noises.
