When did we start using plywood?
Before delving into when was plywood invented, understanding its early use by humans is essential. Plywood, recognized as a versatile and extensively utilized building material, boasts a rich history spanning centuries. The concept of laminating thin layers of wood together to create a stronger and more resilient material can be traced back to ancient times. Among the earliest known users were the ancient Egyptians, who employed a primitive form of plywood as early as 3500 BC in crafting furniture. This early technique enabled them to produce lightweight yet durable items.
However, modern plywood as we know it today began to take shape in the early 20th century. A significant breakthrough occurred in 1905 during the Lewis and Clark Centennial Exposition in Portland, Oregon, where a revolutionary process was showcased. This demonstration introduced a rotary lathe capable of peeling thin layers from logs. These layers were then bonded together with their grains arranged perpendicular to one another, resulting in a product that was notably robust and stable. This method effectively addressed the inherent vulnerabilities of solid wood, such as warping and cracking along the grain.

Commercial production of plywood gained momentum in the 1920s and 1930s, buoyed by advancements in adhesive technology that enhanced strength and water resistance. By the 1940s, plywood had become indispensable in the construction sector, particularly during World War II, when it was extensively used in military infrastructure, aircraft, and naval vessels.
Post-war, plywood surged in popularity, driven by a burgeoning housing market and advancements in mass production techniques. Its versatility, affordability, and ease of use cemented its status as a favored material for diverse applications ranging from furniture to residential construction. Today, plywood remains integral to the construction industry, prized for its durability, versatility, and sustainability, as it can be sourced from rapidly renewable wood species.
When was plywood invented?
So, when exactly was plywood invented? The origins of modern plywood began to take shape in the late 18th and early 19th centuries, marking a pivotal advancement in woodworking and construction materials. It all started in 1797 when Samuel Bentham, an English engineer and naval architect, patented a method for laminating multiple thin layers of wood with the grain running in different directions. This innovation greatly enhanced the strength and stability of the material compared to traditional solid wood.
In the early 1800s, further progress in plywood manufacturing followed. By 1865, Immanuel Nobel, father of Alfred Nobel (the inventor of dynamite and founder of the Nobel Prize), had developed a rotary lathe capable of producing thin layers of wood from logs. This breakthrough allowed for the efficient production of uniform sheets of wood that could be bonded together to create plywood.
The next significant leap in plywood history occurred in the United States during the late 19th and early 20th centuries. John K. Mayo is credited with pioneering the modern plywood industry in the U.S. with his 1896 patent for a method that involved pressure-gluing multiple layers of plywood. This method standardized plywood production methods and set the stage for its widespread adoption.
Industrial production of plywood gained momentum in the early 1900s. In 1905, plywood was showcased at the Lewis and Clark Centennial Exposition in Portland, Oregon, using a rotary lathe similar to Nobel’s design. This demonstration highlighted plywood’s potential as a durable and versatile building material, igniting increased interest and investment in its production.
Advancements in adhesive technology during the 1910s and 1920s further propelled plywood development. Synthetic adhesives introduced during this period significantly improved the strength and water resistance of plywood, solidifying its place in construction and manufacturing. By 1928, plywood had become a cornerstone material, prompting the establishment of the Douglas Fir Plywood Association (now APA), which standardized plywood grades and sizes, further promoting its widespread use.
The invention and development of plywood between 1797 and 1928 involved a series of technological advances and innovations. From Samuel Bentham’s first patents to industrial-scale production methods in the early 20th century, each step contributed to making plywood the essential building material it is today.

What are the Three Types of Plywood?
There are three primary types of plywood, each tailored for specific applications: softwood plywood, hardwood plywood, and marine plywood.
Softwood plywood
Softwood plywood is the most commonly used variety, especially in the construction sector. It’s typically manufactured from softwood species like pine, fir, or spruce. Known for its robustness and longevity, softwood plywood is favored for structural purposes such as roofing, flooring, wall cladding, and general building framing. Its affordability and availability in large sheets make it practical for extensive construction projects. Softwood plywood is graded variably, ranging from Grade A, which boasts a smooth, knot-free surface, to Grade D, which may exhibit more imperfections while maintaining structural integrity.
Hardwood plywood
Hardwood plywood, on the other hand, is crafted from hardwood species such as oak, birch, maple, and walnut. Valued for its aesthetic appeal, this type of plywood finds frequent use in furniture making, cabinetry, and interior applications requiring a refined finish. Hardwood plywood tends to be pricier than its softwood counterparts due to the cost of hardwood veneers and higher production standards. Grades range from Grade A, featuring a flawless surface ideal for staining or painting, to lower grades with more knots and imperfections suitable for various applications.
Marine plywood
Marine plywood represents a premium grade designed specifically for wet environments. Constructed from durable face and core veneers, typically of hardwood species, marine plywood is bonded with waterproof adhesives. This construction grants marine plywood exceptional resistance to moisture, rot, and delamination. It’s commonly employed in boat building, docks, and other settings where exposure to water is frequent. Stringent manufacturing standards ensure minimal defects, ensuring reliability and longevity. Although more costly than standard plywood, the resilience and durability of marine plywood justify its investment for demanding projects.

Is plywood stronger than solid wood?
Plywood is often considered more durable than solid wood in many applications due to its unique structure. It is arguably the most durable and sturdy material available. Furthermore, plywood comes in a variety of qualities, so you can choose the one that fits your budget. Plywood is made by gluing thin layers of wood together, with the grain of each layer running perpendicular to the top layer. This cross-grain structure distributes the natural strengths and weaknesses of the wood more evenly throughout the board, reducing the likelihood of warping, splitting, and cracking that can occur in solid wood.
A key advantage of plywood lies in its dimensional stability. Unlike solid wood, which tends to expand and contract with fluctuations in humidity and temperature, plywood’s cross-grain construction helps it maintain stability and retain its shape across different environmental conditions. This quality makes plywood particularly suitable for critical construction applications such as subflooring and wall cladding, where maintaining structural integrity is paramount.
Furthermore, plywood can be manufactured in large, standardized sheets, a feat not always achievable with solid wood due to natural variations and imperfections in tree growth. This consistency allows for predictable performance and facilitates ease of use in extensive construction and manufacturing projects.
Plywood’s engineered structure gives it advantages over solid wood in terms of stability, resistance to warping, and uniformity, making it a preferred choice for many construction applications. However, the choice between plywood and solid wood ultimately depends on the specific requirements of the project at hand.
