Estimating the term…
A panel includes about 0.1% to about 95% by weight of a ground renewable component. In an embodiment, the panel has at least one core comprising: from about 0.1% to about 95% by weight of the ground renewable component; from about 0.1% to about 95% by weight of one or more fibers; and from about 1% to about 30% by weight of one or more binders, all based on dry panel weight. In an embodiment, the ground renewable component has a particle size distribution whereby less than 5% of the particles are retained by a mesh screen with openings of about 0.312 inches and less than 5% of the particles pass through a mesh screen with openings of about 0.059 inches. A method for manufacturing such panels is also provided.
An acoustical panel having a panel core comprising:
An acoustical panel having a panel core comprising:
A panel for use as a building material, wherein said panel is formed from an aqueous slurry including an inorganic fiber component, starch, water and a renewable component, about 0.1% to about 95% by weight of the panel, after removal of the water, being of the renewable component, wherein said panel has at least one of a Ceiling Attenuation Class value of at least about 25 and a Sound Transmission Class value of at least about 25.
A panel for use as a building material, wherein said panel is formed from an aqueous slurry including an inorganic fiber component, starch, water and a renewable component, about 0.1% to about 95% by weight of the panel, after removal of the water, being of the renewable component, the renewable component being reduced in size such that no more than 5% by weight of the renewable component is retained by a mesh screen with openings of about 0.312 inches, wherein said panel has at least one of a Ceiling Attenuation Class value of at least about 25 and a Sound Transmission Class value of at least about 25.
