A: No, this product is not rated to be used as flooring. It may be used as an underlayment only, not as a finished floor.
The minimum thickness of plywood for subflooring is about 5/8 inch. Since it does not hold fasteners as well as plywood, OSB must be a little thicker, or at least 23/32 inch.
Upgrading to 7/8″ OSB Provides Floor-Performance Benefits for Energy-Efficient Homes. For decades, 23/32″-thick OSB has been the most commonly used thickness of OSB subflooring.
Firstly 7/16 is a roof or wall sheathing and is not for flooring.
One of the main advantages of OSB is its strength and durability, which makes it an ideal choice for structural applications such as flooring, wall sheathing, and roofing.
The service life of OSB is indefinite (expect 50 years or longer) if it is used and protected properly. 2. OSB should not be used where it is permanently exposed to the outdoor environment unless panels are qualified as Exterior (e.g. siding) and recommended coating is periodically renewed.
“The major disadvantage of OSB is that if it gets exposed to significant amounts of water or moisture, the edges expand by up to 15% ... especially if they are cut edges. This swell will then telegraph onto the shingles or some flooring," according to PATH.
Does Weyerhaeuser OSB Floor Sheathing Have an Up and Down Face? The side with the grade stamps is intended to be installed down to allow for the stamps to be visible from an unfinished lower level.
457 People have purchased this in the past week. Performance-rated panel for use in general construction as roof decking and wall and floor sheathing. OSB (Oriented Strand Board) is engineered to provide a strong, stable panel that resists delamination and warping.
The APA (the Engineered Woo Association) recommends that construction professionals leave a 1/8-inch gap between each panel edge and end joint. As ambient moisture changes, your OSB or plywood panels will expand and contract.
Both plywood and OSB are effective choices for your subfloor needs. Plywood is a better option for projects that require a lot of cutting and molding, while OSB is a good option for those who need to cover areas where moisture exposure may be an issue.
OSB can accommodate glue-down, nail/staple or floating hardwood installations. With glue-down, follow the hardwood flooring manufacturer's guidelines.
DryMax® High-Performance OSB is not only the most moisture-resistant OSB sub-floor Georgia-Pacific manufactures, it's also designed to help prevent costly and time-consuming joint sanding. No wonder DryMax® High-Performance OSB carries a 500-day no-sand warranty. It's performance you can count on – day in and day out.
Subfloor sheets for both OSB and plywood come in 4 by 8 or 4 by 12 sheets. Thicknesses for products used for subfloors are generally 23/32 inch (just under 3/4 inch), but thicker sheets are available where building codes call for them.
For the curious – 7/16” OSB has a span rating of 24/16 and with supports every 24 inches is good for a roof live load of 40 psf (pounds per square foot) with a 10 psf dead load.
Hardwood has been a flooring option for thousands of years. It works well over any type of wood subfloor more than 1/2 an inch thick. If squeaky floors are an issue, some construction adhesive will keep everything nice and quiet. Laminate floors can be installed over any wooden subfloor as long as it's in good repair.

OSB can be manufactured into panels that are larger than plywood. OSB is more uniform, so there are fewer soft spots, such as those that can occur in plywood. OSB is less expensive than plywood. To build a typical 2,400-square foot home, OSB may cost $700 less than plywood.
Improper Spacing Between Panels
Like any wood product, OSB will expand and contract after installation; without a small gap between panel ends, the expansion could cause buckling. Most manufacturers recommend 1/8 inch at panel ends and edges.
an expansion gap of at least 1.5mm-2mm should be allowed between each panel.
OSB also brings a lot of structural qualities that make it a suitable choice for flooring. The manufacturing methods for OSB give it a high durability, and can handle lots of weight.
Strong Lifespan: The lifespans of engineered woods can often be a key drawback, but OSB panels boast a longer lifespan, offering 30 to 60 years of dependable performance. This further makes them a cost-effective choice, as they will not need to be replaced as often.
Strength. OSB and plywood are very similar in terms of strength, but plywood is stiffer than OSB by a factor of approximately 10%.
