Water-resistant OSB''3''
OSB (Oriented Strand Board) is a high-performance structural board made from wood strands oriented in cross-laminated layers, bonded with moisture-resistant synthetic resins and pressed at high pressure. This composition gives it excellent mechanical strength, dimensional stability, and performance under demanding environmental conditions.
OSB 3 is suitable for both interior and protected exterior applications, and stands out for its balance between strength, versatility, and sustainability.
Characteristics of moisture-resistant OSB 3
- Cross-oriented layers: Wood strands are strategically arranged to maximize strength in both directions, enhancing structural performance.
- High moisture resistance: Rated OSB 3 under EN 300, designed for variable humidity and moderate structural loads.
- Homogeneous and rigid surface: Ensures dimensional stability and reduces deformation, even in demanding conditions.
- Technical and uniform format: Available in various thicknesses and dimensions to suit lightweight or modular construction systems.
Benefits of moisture-resistant OSB 3
- Structural strength guaranteed: Capable of supporting loads and stresses, ideal for floor slabs, frames, or reinforcements.
- High durability in humid environments: Maintains integrity under elevated humidity (when correctly installed and protected from direct exposure).
- Sustainability: Made from fast-growing wood with a low-waste, optimized manufacturing process.
- Cost-effective: A technical solution at a lower cost than other structural materials like plywood.
Applications of moisture-resistant OSB 3
- Wall and floor systems: Used as structural substrate for floors, ceilings, and roofs, in both new construction and renovation.
- Cladding and linings: Suitable as a base for protected interior and exterior finishes.
- Dry and prefabricated construction: Widely used in light framing, modular buildings, passive houses, and timber structures.
- Furniture industry: Also used for technical furniture or industrial packaging due to its strength and stability.
OSB 3 must be installed following the manufacturer’s guidelines and with the proper protection measures for outdoor environments (e.g., under roofing, ventilated cavities, or additional treatments). It is not intended for structural use in areas with direct and prolonged water exposure or without protection.
