The screw press, probably invented in Greece in the 1st or 2nd century bc, has been used since the days of the Roman Empire for pressing clothes. Part owner and plant manager Gustav Carlson decided to laminate wood panels from a variety of Pacific Northwest softwoods. Instead of solid sheets of veneer, OSB is made of small wood strands that are glued together in cross-laminated layers. Vancouver Plywood Company (12) However, since ASTM D5055 does not specify required levels of performance, individual manufacturers of I-joists generally have their own proprietary company standards that govern the everyday production practice for their products. 7. This manner of inventing plywood has occurred repeatedly throughout history. A 1901 patent from Switzerland signaled the true beginning of glued laminated timber construction. It should be noted that this is a voluntary standard and not all I-joist manufacturers have chosen to produce PRI-400 products. G-P Fordyce (20) The Douglas Fir Plywood Association was among the first to take advantage of a 1938 law that permitted registration of industrywide trademarks, which allowed plywood to be promoted as a standardized commodity rather than by individual brand names. This was originally done due to a shortage of fine wood. Tongue and groove is a method of fitting similar objects together, edge to edge, used mainly with wood, in flooring, parquetry, panelling, and similar constructions.Tongue and groove joints allow two flat pieces to be joined strongly together to make a single flat surface.

[1] Softwood plywood is usually made either of Douglas fir or spruce, pine, and fir, and is typically used for construction and industrial purposes. West Coast Plywood Corporation (16) The market took off and the industry enjoyed steady growth during the Jazz Age. A common reason for using plywood instead of plain wood is its resistance to cracking, shrinkage, twisting/warping, and its general high degree of strength. Plywood is a popular choice for residential and light-duty construction and is made from thin sheets of veneer that have been peeled from debarked wood. Plywood’s growing reputation as a strong and durable construction material was soon put to the extreme test by war. Although the use of two or three layers of wood veneer is ancient, modern 4-by-8-foot (1.2 m × 2.4 m) sheets of plywood with 5–11 core layers of veneer were invented in the early 20th century, and began to become common by the Second World War. 12CE01029. Although some were skeptical, production rocketed to 7.8 billion feet in just five years, and by 1975 U.S. production alone exceeded 16 billion square feet, more than double the forecast.

Individual companies didn’t have the technical or in most cases marketing resources to research, develop and promote new uses for plywood. Shaik.Rizwana. World War II was a proving ground for plywood. This consensus standard provides guidelines for the evaluation of mechanical properties, physical properties, and quality of wood I-joists and is the current common testing standard for I-joists. These are stacked together with the direction of each ply’s grain differing from its neighbours’ by 90° (cross-banding). Two of the edges will have “grooves” notched into them to fit with the adjacent “tongue” that protrudes from the next board. Hence, finishing cost may reduce by the use of plywood. Adhesive and technology improvements eventually led to the manufacture of structural plywood from Southern pine and other species, and in 1964 the Association changed its name to American Plywood Association (APA) to reflect the national scope of its growing membership. The Canadian Standards Association published the first Canadian Plywood Standard in 1953 based on specifications developed by PMBC. The new association struggled until, in 1938, it hired a legendary business development guru, W. E. “Diff” Difford. Sign In Failed. The earliest idea for plywood was conceived in 1797, when Samuel Bentham first applied for patents that covered the machine production of veneers. A breakthrough came in 1934 when Dr. James Nevin, a chemist at Harbor Plywood Corporation in Aberdeen, Washington, finally developed a fully waterproof adhesive. Because of this construction method, plywood is less susceptible to expansion and shrinkage.
