This study was designed to determine some physical and mechanical properties of laminated veneer lumber (LVL) made of black alder (Alnus glutinosa). Veneers were prepared from 2-mm and 4-mm-thick black alder and glued using polyvinyl acetate (PVA) and polyurethane (PU) adhesives. Results showed that the specific gravity and mechanical properties of the LVL produced from 2-mm veneers were higher compared to those from 4-mm veneers. In other words, as the thickness increases, a decrease is observed in the specific gravity and mechanical property values. Except for nail- and screw-holding strength values perpendicular to the glueline, all the other values obtained with the PVA adhesive were higher compared to those obtained with the PU adhesives.
