Laminated Veneer Lumber

…Usually, laminated veneer lumber is called laminated lumber and is treated separately. Laminated veneer lumber is often called LVL, an abbreviation of laminated veneer lumber. The manufacturing process of LVL is similar to that of plywood, and its performance is similar to that of laminated lumber, but its characteristics include: (1) higher product yield than that of laminated lumber, (2) long pieces can be obtained continuously from short logs, (3) the dispersion of defects reduces the variation in material quality, just like with laminated lumber, but since there are generally more layers than with laminated lumber, the variation is even smaller, and (4) it is easy to carry out chemical treatments such as preserving rot and preventing insects. …

…通常，ひき板積層材は集成材と呼ばれ，独立して取り扱われる。単板積層材は，英語のlaminated veneer lumberを略してLVLと呼ばれることが多い。LVLの製造工程は合板に，その性能は集成材に類似しているが，その特徴は，(1)製品歩留りが集成材に比べて高い，(2)短い丸太から連続的に長尺材が得られる，(3)欠点の分散によって材質のばらつきが小さくなることは集成材と同じであるが，一般に集成材より積層数が多いので，ばらつきはさらに小さくなる，(4)防腐，防虫などの薬品処理が容易に行われるなどがあげられる。…
