What is osb board ?

OSB is Oriented strand board, is the upgrading of the traditional particleboard products, its mechanical properties with directionality, durability, moisture resistance, and dimensional stability than ordinary particleboard. With a small expansion coefficient, no distortion, good stability, uniform material and nail holding high performance.


OSB is manufactured in a cross-oriented pattern similar to plywood to create a strong, stiff structural panel. OSB is composed of thin rectangular-shaped wood strands arranged in layers at right angles to one another, which are laid up into mats that form a panel. OSB is bonded with water-resistant adhesives. Most panels are also treated with a sealant on the panel edges to guard against moisture penetration during shipment.

As an added feature, panels are often textured on at least one side to provide a slip resistant surface. OSB uses the wood resource very efficiently, in part because sheathing panels can be made using smaller, younger fast-growing tree species, such as aspen and southern yellow pine. Plus, about 85-90 percent of a log can be used to make high quality structural panels, and the remainder--bark, saw trim, and sawdust can be converted into energy, pulp chips or bark dust.

OSB, or Oriented Strand Board, is a type of engineered wood panel commonly used in construction and woodworking. It's made by compressing and bonding together strands or flakes of wood with adhesive and heat. OSB is known for its strength and versatility, and it has several important uses:

  • Construction: OSB is widely used in construction for sheathing, subflooring, and roofing. It's a cost-effective alternative to plywood and provides good structural stability. It's often used as sheathing for exterior walls and roofs, helping to add rigidity and strength to the building structure.

  • Furniture and Cabinetry: While not as aesthetically pleasing as hardwood plywood, OSB is sometimes used in the construction of furniture and cabinets, particularly in situations where its strength and low cost are more important than its appearance.

  • Subflooring: OSB is a popular choice for subflooring in residential and commercial buildings. It provides a smooth, flat surface for the installation of finished flooring materials such as hardwood, carpet, or tile.

  • Packaging and Pallets: OSB can be used for packaging materials, crates, and pallets due to its strength and durability.

  • Decorative Use: Some DIY enthusiasts and interior designers have used OSB for its unique, industrial look in home decor projects. It can be sanded and finished for a rustic or modern aesthetic.


Oriented Strand Board (OSB) comes in various grades, each designed for specific applications based on their quality, appearance, and performance characteristics. The grading system for OSB may vary somewhat by region and manufacturer, but here's a general overview of the typical grades you might encounter:

  • OSB-1: This grade is sometimes called "Interior OSB." It's suitable for use in dry conditions and is often used for general-purpose construction, including subflooring and roof decking. OSB-1 is not meant for exposure to moisture or outdoor use.

  • OSB-2: This grade is also for use in dry conditions and is appropriate for interior applications. It may be used for sheathing, flooring, and other construction purposes, but it should not be exposed to moisture or the elements.

  • OSB-3: OSB-3 is engineered for use in humid conditions. It has improved moisture resistance and is commonly used in construction projects where the material might be exposed to occasional wetting during construction, but not for long-term exposure to the elements.

  • OSB-4: This grade is designed for structural applications where long-term exposure to moisture is expected. It's suitable for applications like marine environments or outdoor construction projects. OSB-4 offers the highest level of moisture resistance among standard OSB grades.

  • OSB-Grade 1: This grading system may be used in some regions. It's generally similar to OSB-1, suitable for interior use in dry conditions.

  • OSB-Grade 2: This grading system is similar to OSB-2, designed for dry interior applications.

  • Exposure 1: In the United States, the APA (Engineered Wood Association) grading system uses "Exposure" ratings instead of numbers. 

  • Exterior: Some manufacturers may label their OSB as "Exterior" grade. This is designed for sheathing and other construction purposes where the material will be exposed to weather conditions.

  • Subfloor: OSB can be specifically graded for use as subflooring. Subfloor-grade OSB is often tongue-and-groove to provide a smooth, level surface for finished flooring materials.

  • Roof Sheathing: Roof-grade OSB is engineered for use in roof decking applications, providing both strength and moisture resistance for the roof structure.
