The minimum design values for Mass Ply exceeds the minimum design values of E2 CLT defined by PRG-320 in each comparable thickness in major force direction. E2 CLT is the most comparable grade of CLT in terms of engineering and species that we have to compare to Mass Ply.
Mass Ply uses about 20% less wood than CLT and is as strong as or stronger than other SCL products. In addition, the dense layering of wood veneers in Mass Ply can result in high levels of thermal insulation. Mass Plys can be produced in varying lengths and thicknesses from small-diameter, fast-growing trees, negating the need for using larger trees to produce larger formatted pieces of lumber.
Finally, wood framed buildings have been typically limited to four stories due to fire concerns. The predictable char rate of Mass Timber Panels allows buildings to be built taller with wood, allowing code approved multi-story structures out of wood up to 18 stories anticipated in the next iteration of the International Building Code (IBC).
