What thickness is OSB board?
They are fairly straightforward but each one is fairly specific. The thickness of OSB that you need varies on where it is used in a building. Typically 3/4″(18mm) for floors and 3/8″ (9mm) for walls and 1/2″ (11mm) roof. Also make sure that you get your supporting timbers at the correct spacing.
What’s the difference between OSB2 and OSB3?
OSB2 is great for structural, non-load bearing projects in dry conditions whereas OSB3 performs better for structural, load bearing use and for use in humid conditions.

What is the difference between OSB 3 and OSB 4?
SMARTPLY OSB4 is approximately 30-35% stronger and 20% more moisture resistant than OSB3 and is therefore a very cost-effective alternative in humid and high-load structural applications to a similar performing exterior structural plywood marked as “EN 636-3 S” (previously “WBP”1).
Can OSB 3 board get wet?
As a general rule, most OSB are water resistant. Due to their construction process using wood strands, resins and wax they come fairly water resistant.
What is stronger OSB or plywood?
Osb is stronger than plywood in shear. Shear values, through its thickness, are about 2 times greater than plywood. This is one of the reasons osb is used for webs of wooden I-joists. However, nail-holding ability controls performance in shear wall applications.
Should OSB be installed vertically or horizontally?
If the height of a wall is less than 8-feet, install the plywood (or OSB) vertically. If the height of a wall is greater then 8-feet, install the plywood (or OSB) horizontally.

What side of OSB goes down?
OSB also has stamping that reads “This Side Down”. This directs the worker on the correct orientation of the board when installing. The side with the stamp is the smoother side. When installed smooth side down, the rough surface will then face up and give the worker traction for safety.
What side of OSB faces out?
Using OSB Safely When installing in vertical applications such as wall sheathing, you’ll want to orient the smooth or stamped side facing out. The smooth side has a better moisture resistance and will ultimately provide better performance against weather.
