History of Plywood – Origins
Ancient “Plywood”
The use of layers of veneers, or thin slices of wood, can be traced back to the ancient Egyptians and Chinese. They perfected the technique of gluing these veneers together to create laminated woods, utilized for furniture and construction. This method made the most of scarce wood resources, while also providing enhanced durability and resistance to warping, compared to solid wood.
Immanuel Nobel and the Invention of Plywood
Immanuel Nobel made significant advancements in the 19th century. Originating from Sweden, Nobel refined the process of creating plywood by using thin layers of veneers bonded with glue. His innovation included the idea of arranging the wood grains at right angles to each other, dramatically improving the strength of the resulting material. This was the first modern iteration of plywood which we see today.
The 19th Century Development of Plywood
The industrialization period fostered new technologies, enabling more efficient production of laminated woods. The advent of rotary slicing and the invention of steam and mechanical presses were game-changers.
