One. What is a fine-grained wood board?
Plywood is a type of engineered wood product manufactured by bonding together thin strips of wood or honeycomb cardboard cores, covered with one or more layers of plywood on both sides, and then compressed under heat and pressure.
Veneer plywood has excellent screw-holding capacity, high strength, and possesses characteristics such as rigidity, sound absorption, and thermal insulation. It also has a low moisture content, typically between 10% and 13%, making it easy to process and widely applicable.
Plywood is more stable than solid wood, but it is susceptible to moisture. When installing, it should be avoided in kitchens and bathrooms.
Two. What is OSB board?
The primary raw materials for OSB (Oriented Strand Board) are softwood and hardwood species, such as saplings and fast-growing trees, along with their small branches and trunks. The manufacturing process involves drying, gluing, orienting, and hot pressing these wood strands into specific geometric shapes.
"Eu-sun board utilizes high-grade, environmentally friendly adhesives that comply with European environmental standards EN300. Its formaldehyde emission level is significantly lower than that of other boards, making it one of the highest-grade decorative boards available in the market."
The market price of Orient Board is comparable to that of high-grade particleboard, and in terms of both environmental performance and physical properties, Orient Board offers comparable and good characteristics.
Three. Choosing between fine wood boards and OSB for the base layer.
1、Plywood is environmentally friendly.
Early OSB (Oriented Strand Board) was primarily imported from abroad, with suppliers claiming excellent environmental performance and compliance with European E0 standards. Over time, plywood, a traditional decorative and finishing material, has also achieved E0-level standards due to advancements in production equipment and the use of environmentally friendly adhesives. based on the composition of the board products, it is evident that plywood requires significantly less adhesive than OSB, resulting in better environmental performance.
2、OSB (Oriented Strand Board) offers excellent moisture resistance and low deformation characteristics.
Despite retaining good moisture permeability and wood fiber from natural wood, plywood still exhibits defects such as deformation, delamination, and cracking, lacking the stability and moisture resistance of OSB (Oriented Strand Board). OSB, with its three-layer structure consisting of veneer laid longitudinally and core veneer laid horizontally, eliminates the internal stresses of wood by uniformly distributing the veneer. OSB, manufactured through high-temperature and high-pressure molding, has a closely connected internal structure, offering advantages such as low expansion coefficient, good moisture resistance, and small deformation coefficient.
3、Fine-grained wood panels are easy to construct.
Saperboard is lightweight, easy to cut and process, and offers convenient construction. While OSB (Oriented Strand Board) has high density and hardness, which are also its drawbacks, making it difficult to nail into the board. This is also a reason why some carpenters dislike this type of board. Additionally, the surface and edges of OSB boards are rough and not as smooth as those of Saperboard.
4、The plywood has excellent structural strength.
OSB (Oriented Strand Board) completely alters the internal stress of wood. When laid in an alternating pattern, OSB boards, which are formed through high-temperature and high-pressure processing, exhibit high structural strength, good load-bearing capacity, stable performance, and resistance to deformation. While plywood can be prone to warping, delamination, and cracking, its vertical load-bearing capacity is superior to that of OSB.
