Osb Board for Walls

OSB Board for Walls is a structural board made of wood chips arranged in a directional manner and bonded under high pressure, which is optimized for wall applications. Its unique manufacturing process gives the board high strength, moisture resistance and environmental protection, making it an ideal choice to replace traditional plywood and solid wood boards in modern buildings. Compared with traditional materials, OSB wall panels perform better in load-bearing capacity, dimensional stability and construction efficiency, and are suitable for wall structures in residential, commercial and industrial buildings.

Features of OSB Board for Walls

1. Directional arrangement of wood chips

The surface wood chips are directional along the length or width of the board to form a reinforcement layer similar to "armor", with a transverse bending strength of ≥35MPa and a longitudinal bending strength of ≥50MPa, which is far superior to ordinary particleboard.

2. Multi-layer cross structure

The internal wood chips are randomly laid, and the surface is directional, forming a criss-cross stable structure with an expansion coefficient of ≤0.2%, which adapts to temperature changes and reduces the risk of cracking.

3. Moisture-proof and weather-resistant

Waterproofing agent is added during the production process, and the water absorption thickness expansion rate is ≤8% (24-hour immersion), which is better than ordinary plywood (≤15%) and is suitable for humid environments such as basements and bathrooms.

After 72 hours of hot and cold cycle test (-20℃ to 60℃), the board size change rate is ≤0.3%, and the weather resistance grade meets the ASTM D1037 standard.

4. Environmental protection and sustainability

MDI formaldehyde-free glue is used (formaldehyde emission ≤0.005mg/m³, in line with ENF grade standards), VOC emission ≤0.05mg/m³·h, which is much lower than the F4 star standard (≤0.3mg/m³·h).

The raw materials are small-diameter wood and thinning wood, and the proportion of FSC-certified wood is ≥80%. The energy consumption of the production process is reduced by 30%, and carbon emissions are reduced by 25%.

5. Sound insulation performance

The airborne sound insulation is ≥32dB (8mm thickness), and can reach 45dB when matched with sound insulation cotton, meeting the sound insulation requirements of residential partition walls (GB 50118-2010).

6. Thermal insulation performance

The thermal conductivity is ≤0.13W/(m·K), which is better than concrete (1.74W/(m·K)), and can reduce the wall thickness by 10%-15%, improving the energy efficiency of the building.

Application scenarios of OSB Board for Walls

1. Residential building walls

Inside and outside wall base: 18mm thick board is used for load-bearing wall base, matched with gypsum board or calcium silicate board, single point load ≥150kg, and seismic performance is improved by 20%.

Partition wall: 8mm thick board is used for lightweight partition, construction efficiency is improved by 40%, sound insulation performance is up to 35dB, suitable for apartments, hotels and other spaces.

2. Commercial building exterior wall

Curtain wall base: used for base support of metal curtain wall and stone curtain wall, with wind pressure resistance of level 9 (GB/T 15227-2019) and fire resistance limit ≥1 hour.

Decorative exterior wall: the surface can be painted with real stone paint or fluorocarbon paint, and the insulation layer can form a composite wall with U value ≤0.3W/(m²·K), which meets the passive house standard.

3. Industrial building wall

Clean workshop wall panel: used for clean wall panel of electronic and pharmaceutical factories, with surface smoothness of Ra≤1.6μm, antibacterial rate ≥99.9%, in line with GMP certification.

Cold storage wall: with polyurethane insulation layer, cold bridge loss is reduced by 30% and energy consumption is reduced by 15% under -25℃ environment.

4. Temporary buildings and mobile houses

Container house wall: 8mm thick plate is used for container house side panel, which reduces dead weight by 20%, transportation cost by 15%, and service life is extended to 15 years.

Post-disaster emergency room: quick assembly, single-room wall installation time ≤ 2 hours, impact resistance ≥ 5kJ/m², suitable for post-disaster reconstruction such as earthquakes and floods.

5. Creative space and art installations

Exposed decorative wall: using the natural texture of the board, with LED light strips, to create an industrial style background wall, suitable for commercial spaces such as restaurants and cafes.

Acoustic device: through punching and carving processes, sound-absorbing panels and diffusers are made, with NRC (noise reduction coefficient) of 0.85, which improves the acoustic quality of the space.

Cleaning and maintenance of OSB Board for Walls

1. Moisture and mildew

Humidity control: The storage environment humidity is kept between 40%-60%, avoiding direct contact with water or long-term exposure to humid environments.

Anti-mildew treatment: It is recommended to apply waterproof paint or mildew inhibitor for outdoor use, and regularly check whether the edges are warped or moldy.

2. Surface protection

Avoid scratches: Use soft gaskets during construction to avoid scratches from hard objects; use shockproof packaging during transportation to reduce the breakage rate to less than 0.3%.

Anti-ultraviolet: Long-term exposure to sunlight requires UV protection paint to prevent the board from discoloration, and the color difference ΔE≤2.0 (CIE 1976 standard).

3. Regular inspection and maintenance

Connector inspection: Check whether the hardware is loose every 6 months, tighten or replace it in time to avoid structural instability.

Surface repair: Scratches can be filled with the same color wood wax oil, and deep scratches require replacement of the board or veneer repair.
