Why Choose OSB Sterling Board?
OSB Sterling Board delivers reliable performance for construction projects demanding structural integrity and moisture resistance. OSB boards are designed to handle more stress and are stronger and more stable than alternative sheet materials like plywood, making them suitable for load-bearing applications in construction.
-
Structural Strength: Sterling OSB3 is a precision-engineered structural board that is suitable for load-bearing applications in both commercial and domestic construction. OSB has no weak spots or voids due to its uniform composition.
-
Moisture Resistance: OSB3 is specifically designed for load-bearing applications in humid conditions, providing durability and moisture resistance. Using OSB3 is recommended for Sheffield’s wet climate over OSB2.
-
Cost-Effective: OSB is generally 15–30% cheaper than plywood while offering comparable structural performance. OSB offers better pricing for structural work than plywood due to its production efficiency.
-
Versatile Applications: OSB boards are commonly used as structural panels for roofing, wall sheathing, flooring, and ceilings in construction projects. Sterling OSB3 is suitable for a variety of applications, including timber frame housing, flat and pitched roofs, wall sheathing, and portable buildings.
-
Professional Quality: OSB boards typically feature a rough surface with a particoloured appearance due to the criss-cross arrangement of the outer wood strips, which contributes to their structural integrity. OSB is uniform across the entire sheet due to the absence of internal voids, knotholes, or core gaps.

OSB Sterling Board Sizes and Applications
OSB, or Oriented Strand Board, is an engineered wood product made by layering strands of wood in specific orientations, which enhances its strength and durability. We stock some of the most popular sizes to meet your construction requirements:
-
11mm OSB Sterling Board: Commonly used for wall sheathing and roof decking. This versatile thickness provides the structural performance needed for general construction while keeping on-site weight manageable.
-
18mm OSB Sterling Board: Ideal for flooring, heavy-duty decking, and load-bearing applications. This thickness delivers the rigidity required for structural flooring within standard joist spacings.
-
Standard Panel Sizes: Timber Traders currently stocks 2440x1220mm (8ft x 4ft) and 2400x606mm (8ft x 2ft) T&G sheets available from stock. These dimensions suit standard construction layouts and minimise waste.
-
Custom Requirements: Custom sizes and thicknesses available on request. Contact us to discuss specific project needs.
-
Sustainable Construction: All boards are FSC certified for sustainable construction. OSB uses nearly 100% of the logs from small, fast-growing trees, making it a more eco-friendly option than traditional timber products.
OSB boards are available in different grades, primarily OSB2 and OSB3, which are suitable for structural use in various conditions. Timbertraders primarily stocks OSB3 sheets.
OSB2 is designed for dry, non-load-bearing applications, while OSB3 can be used in both dry and humid conditions for load-bearing applications.

OSB STERLING BOARD FAQs

What are the main differences between 9mm, 11mm, and 18mm OSB Sterling Board?
Thickness determines structural capacity and suitability for applications. 9mm boards are suitable for non-structural interior uses, such as backing panels and lightweight partitions. 11mm boards provide adequate strength for wall sheathing and roof decking under moderate loads. 18mm boards deliver full structural performance for flooring and load-bearing decking applications.
Select thickness based on your specific project requirements. For structural flooring, 18mm is essential to prevent deflection under live loads. For roofing and wall sheathing, 11mm typically meets requirements while reducing material weight and price.
Can OSB Sterling Board be used for outdoor applications?
OSB3 is moisture-resistant, but not fully waterproof; edges should be sealed and surfaces treated if used outdoors. OSB boards can be used in both dry and humid conditions, making them versatile for various construction environments and applications.
For external wall sheathing, roofing substrate, and similar applications, OSB3 performs well when protected by cladding, membranes, or roofing materials. Cover boards promptly after installation and seal cut edges to enhance durability in Sheffield’s wet climate. OSB3 boards are engineered to withstand extreme humidity and dryness, making them suitable for a wide range of environmental conditions.
How do I get the latest prices for OSB Sterling Board?
Call or email for current competitive pricing on OSB Sterling Board. Timber prices fluctuate based on market conditions, supply chain factors, and transport costs. We provide accurate quotes when you contact us with your specific requirements.
Include the thickness, quantity needed, and your postcode for delivery quotes. High volume orders may qualify for improved pricing. Ask when you call.
Is OSB Sterling Board suitable for flooring applications?
Yes. 18mm OSB3 boards are ideal for structural flooring applications. This thickness provides the stiffness required to span standard joist spacings without excessive deflection under foot traffic and furniture loads.
For structural applications requiring superior moisture resistance, OSB3 is a cost-effective choice in modern construction. Ensure joists are level and boards are laid with staggered joints for maximum stability. OSB is more structurally sound than plywood, but its susceptibility to edge moisture, greater weight, and rough texture can limit its application. Note that OSB holds screws and nails less firmly than plywood, so follow the fixing guidelines.
OSB/4 is a heavy-duty structural board for demanding loads in humid environments. Contact us if your project requires this enhanced specification.
