OSB 3 (Oriented Strand Board 3)

OSB 3 (Oriented Strand Board 3) is a strong and versatile engineered wood panel with moisture resistance, designed for structural use in humid conditions like roofs, floors, and walls, made from compressed, cross-oriented wood strands bonded with resin.

OSB 3 is known for its load-bearing capacity, dimensional stability, and use in timber framing, offering a durable, knot-free alternative to plywood

OSB 3 is manufactured to EN 300 standard.

BS EN 300 refers to the European Standard for Oriented Strand Boards (OSB), defining its types, classifications (OSB/1 to OSB/4 for dry to high-strength humid conditions), specifications, and testing methods, acting as the key technical document for these versatile engineered wood panels used in construction and other applications. This product is OSB/3.

Key Aspects of BS EN 300:

• Scope: Covers definitions, classification, and performance requirements for OSB panels.
• OSB Types: Classifies OSB into four main types based on moisture resistance and load-bearing capacity:
• OSB/1: For general use in dry conditions (non-load-bearing).
• OSB/2: For structural use in dry conditions.
• OSB/3: For structural use in humid conditions.
• OSB/4: High-strength structural boards for demanding humid conditions.
