Abstract
A method is provided for forming a fire resistant cellulose product. A fire-retarding solution and a bonding agent are combined with refined cellulose fibers to form a fiber mixture, and the fire-retarding solution and bonding agent are substantially uniformly distributed with respect to the cellulose fibers within the fiber mixture. The fiber mixture is exposed to an actuating element, wherein the actuating element is configured to actuate the bonding agent so as to facilitate cohesion of the cellulose fibers and form the fiber mixture into a fiber board member, the fiber board member having opposing major surfaces. A cellulose sheet member is engaged with each major surface of the fiber board member, such that each cellulose sheet member substantially covers the respective major surface. An associated apparatus is also provided.
