Are 4′ x 8′ sheets of plywood used to make Mass Ply? In what thickness?

Although its name may suggest otherwise, the Mass Ply Panel is composed of 1″ x 4′ x 8′ layers of Laminated Veneer Lumber (LVL), a veneer-based engineered wood product certified under ASTM D5456. The LVL layups have cross plies, which allow the mass timber panel to have strength and stability across both axes of the panel. Our higher performance layups have more long plies than cross plies to achieve greater divs. The 4′ x 8′ sheets are scarf jointed together to achieve a length up to 48 ft. A width up to 11’10” is achieved by using 4′ and 2′ wide panels and staggering the joints as each course gets laid up to the desired thickness.
