Details
OSB sheets are formed by compressing layers of wood strands together with adhesives, with the strands pointing in specific orientations, which gives it its rigidity and strength. Due to its helpful mechanical properties, OSB is commonly used in construction for load-bearing applications. Other common uses of OSB wood sheets are sheathing in floors, roof decking and walls, as well as a material for furniture production.
Using our CNC router we can cut OSB board within +/-3mm tolerance, giving precision accuracy and consistent duplication. If you have a specific shape or size in mind, well be able to make it - all you need to do is draw out your design and send it over to us in either CAD or a sketch format, it’s that simple. Whatsmore, we can also rebate, pocket and cut holes in your OSB board using our CNC router.
Different types of OSB
There are five types of panel classification for OSB sheets, standardised in BS EN 300 in terms of their resistance to water and mechanical performance:
- OSB/0 – No added formaldehyde
- OSB/1 – General-purpose boards and boards for interior fitments (including furniture) for use in dry conditions
- OSB/2 – Load-bearing boards for use in dry conditions
- OSB/3 – Load-bearing boards for use in humid conditions
- OSB/4 – Heavy-duty load-bearing boards for use in humid conditions
We sell OSB/3 boards as standard.
Key Features of OSB Board
Versatile
Our OSB boards are made to withstand the toughest of conditions. In recent years OSB has grown to become a leading material in the construction trade, overtaking a huge market share from plywood. As a great load-bearing material, that can cope with harsh conditions, this board is a perfect option.
Inexpensive
Made from forming wood strands and drying with the addition of adhesives, OSB makes the most of multiple pieces of real wood thereby creating an all-round cheaper product. Also, one metre squared of our thickest OSB board (18mm) costs £38.80, dramatically cheaper than Plywood, which costs £77.83 per square metre (again at our thickest option of 18mm). This makes OSB a more cost-friendly option for DIYers, tradespeople and building companies.
Environmentally Friendly
OSB board is also a greener option when looking for timber supplies. OSB is made from lots of pieces of smaller wood, so can be created by using smaller trees that grow quicker. Plywood on the other hand requires large-diameter trees, which generally need to be harvested from old forest growths- a less green option.
Adaptable
OSB is perfect for painting and finishing for multiple projects and can be a great material for furniture creation, or for use in walls, or in weight-bearing options. It can also be treated with moisture-resistant resins to give it moisture-resistant properties.
Malleable
Our OSB board oak sheets are easy to fabricate and can be cut, drilled and shaped to any requirements, so is a flexible, and attractive material to work with.
OSB Accent Wall Panels for a Bold, Industrial Look
OSB boards are perfect for adding texture and industrial character to any room. Featured here in @georgeg.tattoo's studio, the OSB boards were custom cut by us to fit the height of the wall and installed as accent strips, creating a unique, raw aesthetic that enhances the studio's edgy vibe.
Why choose OSB as as an accent feature? It's known for it's strength and durability, making it ideal for high-traffic areas like tattoo studios, cafes, and workshops. With its rough, unfinished texture, OSB adds an urban, contemporary feel to any space. Our panels are lightweight and easy to install. Whether you're a professional installer or a DIY enthusiast, you can quickly achieve an impactful design upgrade like this one.

Frequently Asked Questions
Are OSB boards waterproof?
No, OSB is not waterproof. The wood strands are bonded together with adhesives that can break down when exposed to moisture over time. OSB should be protected from water exposure.
How long will OSB last outside?
Left untreated and exposed to the elements, OSB will start to delaminate and decompose within 12-18 months. With proper protective finishes applied, it may last 3-5 years as exterior siding or roof sheathing.
Does OSB warp easily?
OSB is less prone to warping than solid wood since the strand orientation minimises expansion and contraction. However, it can still warp if subjected to moisture on only one side for an extended period of time.
How thick should OSB be to walk on?
For flooring applications, OSB should be 18mm or 23mm thick to handle compression and impact forces from regular foot traffic.
Will OSB hold screws?
Yes, OSB provides excellent screw-holding strength comparable to plywood. Pre-drilling is recommended and surface finishes should be applied to protect the embedded fasteners.
