The WoodWave is a unique product embodying significant technological advancements. It transfers loads in an entirely new way, absorbs sound through regular acoustical openings between splices, and is constructed using simple dimensional lumber in a way that meets fire safety requirements. The structural behaviour of the WoodWave becomes apparent when looking at the mechanics of the panel under gravity loading. As the dead, snow, and wind loads are applied to the upper surface of the panel, the forces are distributed by the plywood skin diagonally through the spliced lumber strands and into the supports.
We have developed this novel prefabricated WoodWave structural panel system, employing conventional light frame lumber commonly used in wood frame construction throughout North America, to span large distances - much greater than those possible with conventional nail-laminated or glue-laminated mass timber panels.
Each WoodWave panel comprises of several hollow triangular composite sections (Vees) of built-up lumber. The two sloping faces of each Vee splay out from a central bottom chord, and are built up from successive strands of the same material laid on edge. Each strand is offset from the one below it and fastened together for structural composite action. Alternating strands are continuous, with adjacent strands comprising short lengths of lumber separated longitudinally by gaps of varying length. The voids thus created lighten the structure and enhance acoustic performance. Internal plywood gussets at the supports and along the span give shape and lateral stability to the sections. The incremental longitudinal offset of each successive row of blocks stitched together creates a composite action, turning short pieces of dimensional lumber into a strong integral structural element.
The WoodWave is available in many sizes and can be customized to any project, span, loading or orientation. The WoodWave easily facilitates the pre-installation and concealment of MEP services within the hollow Vees.

Our WoodWave Fabrication Process
Panel fabrication involves a completely unique process including a custom computer numerically controlled (CNC) machine which we developed to cut, splice, and screw-reinforce each 2x4 strand. The end screws inhibit checking near the ends of the highly stressed 2x4s. The structural performance of the composite multiple span panel is complex, but each component performs at optimal efficiency. Factory fabrication of the panels included the installation of a black fabric liner and mineral wool insulation to meet fire codes and acoustical requirements.
