Abstract: An insulation composition including a biomass-derived polymer, a cellulose component, and a fire retardant applied to at least a portion of either or both of the biomass-derived polymer and the cellulose component. The biomass-derived polymer may be used to bind the cellulose component. The cellulose component may be fibers, cellulose dust, nanocrystalline structure, or a combination. The insulation composition may be formed into batts, assemblies, or boards. The insulation composition may be processed in the field by shredding to form loose fill insulation. The composition may be treated with one or more additives, including an expansion component selected to reduce the density of the composition.

Abstract: A cellulose-based laminate product including a first skin, a second skin, and a mat matrix positioned between the first skin and the second skin. The mat matrix includes a plurality of cellulosic fibers formed into agglomerations with voids contained therebetween. The plurality of cellulosic fibers may be Short Fiber Residuals alone or in combination with other fibers, including flexible organic fibers and nanocellulose fibers. The mat matrix may be formed in place between the first and second skins. The first and second skins may be treated for moisture resistance. The laminate product of the present invention can be used to provide thermal and/or impact insulation for a wide array of applications.
