  2. Wood preservation - Wikipedia

    en.wikipedia.org/wiki/Wood_preservation

    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. Chemical Specialties, Inc (CSI, now Viance) received U.S. Environmental Protection Agency 's Presidential Green Chemistry Challenge Award in 2002 for ...

    en.wikipedia.org/wiki/Tree_girth_measurement

    Slowdown in radial growth rates can occur without slowdown in corresponding cross-sectional area or volume growth. For example, research by Leverett [ 24 ] has shown that even older white pine trees continue to add significant wood volumes, with 11 monitored trees on average adding 11.9 cubic feet (0.34 m 3 ) annually.

  4. Larch - Wikipedia

    en.wikipedia.org/wiki/Larch

    Larch wood is valued for its tough, waterproof and durable qualities. Top quality knot-free timber is in great demand for building yachts and other small boats, for exterior cladding of buildings, and interior paneling. The timber is somewhat resistant to rot when in contact with the ground, and historically was used as posts and in fencing.

  5. Tree volume measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_volume_measurement

    The volume of the branches on the tuliptree was only 64.2% that of the trunk. [15] The President Tree (Sequoiadendron giganteum) [3] was measured in 2012 to have a trunk volume of 54,000 cubic feet (1,500 m 3) of wood and a branch volume of 9,000 cubic feet (250 m 3) of wood in the branches. In this giant tree the branch volume was only 16.7% ...

  6. Volume table - Wikipedia

    en.wikipedia.org/wiki/Volume_table

    A volume table is a chart to aid in the estimation of standing timber volume. These tables are based on volume equations and use correlations between certain aspects of a tree to estimate the volume to a degree of certainty. The diameter at breast height (DBH) and the merchantable height are used to determine the total volume. Difficulties ...

  7. Stere - Wikipedia

    en.wikipedia.org/wiki/Stere

    If the logs are less than 1 m, the volume of visible wood decreases because the voids are better occupied. Thus the "stere" no longer corresponds to 1 m 3 , but to 0.8 m 3 (28.3 cu ft) for 50 cm (19.7 in) logs, 0.7 m 3 (24.7 cu ft) for 33 cm (13.0 in) logs and 0.6 m 3 (21.2 cu ft) for 25 cm (9.8 in) logs.

  9. Laminated veneer lumber - Wikipedia

    en.wikipedia.org/wiki/Laminated_veneer_lumber

    In LVL, the direction of the wood grain is always parallel to the length of the billet. [6] The stacking of these veneers into a complete board, called a billet, creates a single piece of LVL sharing a common direction of wood grain. [1] LVL is typically rated by the manufacturer for elastic modulus and allowable bending stress.
