Why do wood based panels measure 1222×2444 mm
a simple strategy with positive impact .
Wood based panels, such as plywood, OSB, and fiberboard, play a fundamental role in industrialized construction for various reasons:
They are versatile and easily adapt to different construction applications, such as ceilings, floors, walls, structural elements, cladding, and furniture. With just one material, I can build almost anything!
In addition to their versatility, they are lightweight, making handling and quick installation easy. Their precise dimensionality and structural predictability allow for agile and safe assembly, speeding up construction times and reducing labor-related costs.
Wood, used in the manufacture of these panels, is a renewable natural resource that absorbs carbon dioxide (CO2) during its growth. When used in the construction of derived panels, the carbon stored in the wood remains retained in the final product during its lifespan in buildings and structures, acting as a “carbon silo.”
But have you ever wondered why wood panels used in construction measure approximately 1200×2400 millimeters?
The origin of this measurement dates back to the 20th century and the imperial metric system, which is used in the United States, the early manufacturers, and importers of these products.
Thus, the wood panels they manufactured measured 4×8 feet, with each foot being approximately 30 cm. This measurement provided several advantages:
On one hand, it facilitates the transportation and storage of the panels, as they can be easily stacked in trucks or containers. Since 12 x 2.4 m is the standard size of transport containers, storage space is used more efficiently.
Additionally, this measurement aligned well with other standard construction dimensions, such as bricks that conventionally measure 24×12 cm.
Lastly, the 4-foot width, approximately 1220 mm, can be handled by a single worker without the need for auxiliary means, simplifying installation.
This decision, initially based on economic and logistical considerations, ultimately achieves a triple positive impact:
1. Environmental Impact:
In addition to the inherent advantages of wood as a sustainable material, the standardized dimensions of the panel and its easy handling help reduce construction times and, consequently, CO2 emissions. Furthermore, it reduces waste and makes more efficient use of forest resources. Efficiency in transportation, by maximizing container space, in turn reduces emissions during this phase. Finally, these standardized measurements facilitate the potential reuse of the panel if it is dismantled after its useful life.
2. Economic Impact:
The same reasons described in the environmental section apply to the economic impact: greater efficiency in the construction phase, reduced waste and resource usage, fewer transportation needs, all leading to lower economic costs.
3. Social Impact:
The availability of an economical and versatile material facilitates the construction of affordable housing or equipment, democratizing its access to a large part of the population.
On the other hand, the measurement of 1222 mm, manageable by a single person without the need for auxiliary equipment, and the ease of handling, cutting and installation contribute to the safety and health of workers.
We like the idea that a simple decision hides a powerful strategy that positively impacts all phases of design and construction, and the three aspects that define sustainability.
