A building product having improved fire resistance by virtue of solid fire-resistant cladding material attached to at least a portion of one or more surfaces of the building product. The solid fire-resistant cladding material includes wood fiber and binder. The building product can be a wood-based building product, and can be in the form of an I-joist. When an I-joist is used, the solid fire-resistant cladding material can be attached to, for example, the web of the I-joist.

Building products with fire-resistant claddings

Wood-based composites, and methods for their manufacture, are provided. The composites include oriented wooden strands and cured bonding resin connecting adjacent strands. The composites are relatively low-density, having an average dry density of the wooden composites of about 15-28 pounds per cubic foot (pcf). The unique composition of the composites provide improved structural and insulating (thermal and acoustic) properties when compared to traditional engineered wood products (e.g., oriented strandboard).

Thermally insulating low density structural wooden composite

The disclosure relates to foamed binders for wood strand products and methods and systems for producing wood strand products using foamed binders. In some embodiments, the disclosure includes a method for producing a wood strand product from cellulosic particles, the method comprising the steps of foaming a phenol formaldehyde binder to produce a foam, tumbling the cellulosic particles in a rotary blender, applying the foam to the cellulosic particles in the rotary blender, blending the cellulosic particles and the foam so that the foam covers the cellulosic particles, and consolidating the cellulosic particles under heat and pressure.

Foamed binder and associated systems and methods for producing a wood product

The present disclosure includes a wood composite made from cellulosic particles, a binder, and a water-repelling agent. In some embodiments, the water repelling agent includes aliphatic compounds having a molecular distribution between about 16 and about 36 carbon atoms per molecule. In some embodiments, the water-repelling agent has an average molecular weight of about 220 to about 350 Daltons (solids portion). The water-repelling agent may be applied as a wax emulsion or in neat wax form. The present disclosure also relates to a method for manufacturing a wood composite as described above.

Wood composite with water-repelling agent

The present disclosure is directed generally towards floor panels and flooring drainage systems utilizing two or more interconnected improved floor panels. In some embodiments, the disclosure includes a floor panel having a top surface, a bottom surface, a first longitudinal surface, a second longitudinal surface, a first transverse surface, and a second transverse surface. One or more drainage assemblies are located on either the first transverse surface and/or the second transverse surface. Each of the drainage assemblies include one or more drainage slots and one or more drainage notches. Further aspects are directed towards flooring drainage systems comprising two or more interconnected floor panels according to embodiments of the disclosure.
