The present disclosure is directed generally towards fire-resistant wood products and formulations for fire-resistant coatings. In some embodiments, the disclosure includes a fire-resistant coating comprising an aromatic isocyanate (present in a quantity ranging from about 15% to about 39%), castor oil (present in a quantity ranging from about 37% to about 65%), and intumescent particles (present in a quantity ranging from about 1 % to about 40%). Further aspects are directed towards materials such as wood products coated with fire-resistant coatings according to embodiments of the disclosure.
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).

TRUSS AND METHOD FOR SELECTING COMPONENTS FOR CONSTRUCTING A TRUSS
A truss structure comprises an enclosed structure having two or more upper chord elements are arranged in a single plane and connected end-on-end to form an inverted V structure. The inverted V structure has a first end, a second end, and a middle point located between the first end and the second end. The enclosed structure also includes one or more lower chord elements. The one or more lower chord elements are arranged to connect the first end to the second end to form the enclosed structure. The enclosed structure further includes one or more web elements arranged inside the enclosed structure. The one or more web elements connect the two or more upper chord elements to the one or more lower chord elements. The one or more web elements and the two or more upper chord elements each have values representing dimensional instability. The values representing dimensional instability of the one or more web elements are higher, on average, than the values representing dimensional instability for the two or more upper chord elements. Accordingly, the described truss structure has lowered susceptibility to uplift.

A programmed computer or non-transitory computer readable storage media has instructions that are executable by a processor to identify LiDAR data points associated with items of vegetation or other objects. Each LiDAR data point is tested to determine if it lies within the value of a closed surface defined for higher LiDAR points. If so, the LiDAR point is grouped with the LiDAR points associated with a previously identified item of vegetation. If not, a new item of vegetation is identified.
The present disclosure provides compositions formulated to improve water resistance when topically applied as a treatment to a surface (e.g., the surface of a wood product). Wood products treated with the compositions, as well as methods for applying the compositions to a surface, are also provided.
The present disclosure provides compositions formulated to provide water resistance and fire resistance when applied as a coating to a surface (e.g., the surface of a wood product).

METHOD FOR DETERMINING SPAN LENGTHS BASED ON PROPERTIES OF LUMBER
Methods for determining appropriate span lengths for a given piece of lumber for use as a joist and conveying that information to a user are provided. The appropriate span length may be a function of load type, amount of load, bending stiffness, joist spacing, or the like. The span lengths may be conveyed via, for example, printing of a table onto the lumber piece itself. A user may then review the table and determine into which applications the lumber may be implemented. Accordingly, the method of the present invention enables more efficient allocation of lumber towards building needs.
