The U.S. began mandating the use of non-arsenic containing wood preservatives for virtually all residential use timber in 2004. The American Wood Protection Association (AWPA) standards for ACQ require a retention of 0.15 lb/cu ft (2.4 kg/m 3) for above ground use and 0.40 lb/cu ft (6.4 kg/m 3) for ground contact.
In 1971 "Micro=Lam LVL" was introduced. "Micro=Lam LVL" consisted of laminated veneer lumber billets 4 feet (1.2 m) wide, 3 + 1 ⁄ 2 inches (89 mm) thick, and 80 feet (24 m) long. Troutner proved the structural capabilities of his Micro=Lam product by building a house in Hagerman, Idaho, using beams made of Micro=Lam.

This process is similar to the Les Bois Perdure treatment in that it uses a steam environment at atmospheric pressure to treat the wood. However, this process can also be used on "green" wood and was the most widely used commercial process as of 2004. [5] [10] Genuine industrial scale ThermoWood process was developed in Finland in 1990's.
Bunk sizes: 2×4 have 294 pcs, 2×6 have 189 pcs, 2×8 YP have 96 pcs, 2×10 YP have 80 pcs, and 2×12 YP have 64 pcs. (YP= Yellow Pine) The lumber is usually eight, twelve, or sixteen feet long, but can be longer. The ACQ-C product is normally shipped from manufacturer as a concentrated solution that is diluted at the wood treatment plant.
The strands in PSL are clipped veneer elements having a least dimension of not more than 1 ⁄ 4 inch (6.4 mm) and an average length of at least 300 times this least dimension (around 6 ft or 1.8 m). [1] It is a member of the structural composite lumber (SCL) family of engineered wood products. [1]
Glulam brace with plates used for connections Glulam frame of a roof structure. Glued laminated timber, commonly referred to as glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives so that all of the grain runs parallel to the longitudinal axis.
In 1961, at a meeting in Scottsdale, Arizona, the Committee on Grade Simplification and Standardization agreed to what is now the current U.S. standard: in part, the dressed size of a 1-inch (nominal) board was fixed at 3 ⁄ 4 inch; while the dressed size of 2 inch (nominal) lumber was reduced from 1 + 5 ⁄ 8 inch to the current 1 + 1 ⁄ 2 inch.
