A PANEL FOR BUILDING MATERIAL AND METHOD FOR MANUFACTURING THE SAME

A panel includes about 0.1% to about 95% by weight of a renewable component and has at least one of a CAC value of at least about 25， an NRC value of at least about 0.25 and an STC of at least about 25. In an embodiment， the panel has a core including 0.1% to 95% by weight of the renewable component; 0.1% to 95% by weight fibers; and 1% to 30% by weight binders， all based on dry panel weight. The renewable component optionally has a particle size distribution whereby less than 5% of the particles are retained by a mesh screen with openings of 0.312 inches and less than 5% of the particles pass through a mesh screen with openings of 0.059 inches. A method for manufacturing such panels is also provided.
