OSB is extensively used for wall sheathing, floor underlayment, roof cover and I-joist in both commercial and residential building. OSB also is used in furniture, reels, trailer liners and recreational vehicle floors. Figure 3 shows siding and I-joist application of OSB in building construction.
Which is better plywood or OSB?
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.5 days ago.
Is OSB plywood waterproof?
OSB is strong and water-resistant. Every single fiber or piece of wood in an OSB is saturated with a cocktail of resins designed to provide superior strength and waterproofing to the finished product. This type of board is an excellent material for use in waterproofing systems, be they roof, sub-floor or wall.
Is OSB more water resistant than plywood?
OSB is more resistant to moisture absorption but also takes longer to dry out. Plywood absorbs moisture faster but also dries out much faster, but extended moisture exposure can cause plywood to delaminate.
Where Can OSB be used?
Common OSB Applications APA-trademarked OSB is suitable for a variety of end uses including subflooring, single-layer flooring, wall and roof sheathing, sheathing ceiling/deck, structural insulated panels, webs for wood I-joists, industrial containers, mezzanine decks, and furniture.
Can I use OSB for garage walls?
The bottom line is that both OSB & Plywood are suitable for garage walls. They are quite similar as they are both wood structural panels. However, they have some differences: Strength – OSB is twice as strong as Plywood when it comes to shear strength.
Can I use OSB as a subfloor?
OSB subfloor serves as a base under the finish floor (hardwood, engineered wood, vinyl tile, etc.) Most local codes allow OSB to be used for subflooring. It’s always best to check with your local permitting office before using OSB for your subfloor. One advantage that OSB has over plywood is its larger formatting.
Is OSB good for exterior use?
OSB is highly resistant to moisture and can be water and weatherproofed for exterior use using good quality paint or stain. It has superior strength to other wood panels and a slower rate of moisture absorption.
Can OSB sheathing be painted?
OSB, or oriented strand board, has a flaked appearance and bumpy texture. If you want to use OSB as a finish material, you can successfully paint it to make it more attractive and perhaps even improve its utility. But OSB has a few limitations and requires special preparation before you start rolling on the paint.
Can I use OSB instead of plywood?

What holds screws better OSB or plywood?
Group 1 plywood, made from the strongest species of wood such as Southern Yellow Pine, holds screws better than OSB.
Which is cheaper plywood or OSB?
OSB is less expensive than plywood. To build a typical 2,400-square foot home, OSB may cost $700 less than plywood. OSB is considered by many to be a “green” building material because it can be made from smaller-diameter trees, such as poplars, that are often farmed.
Is OSB plywood termite resistant?
No, termites don’t eat OSB. Cement is used in OSB to bond them together, which deters the termites from eating OSB. Cement saps the moisture and cellulose out of the OSB that makes OSB inedible for the termites.
Can OSB be used for roofing?
Both OSB and plywood panels can cut and installed on a roof using conventional roofing equipment. They have similar structural characteristics, and can be used interchangeably. OSB is now the most-used sheathing and subflooring material for new roofs and roof replacements.
Can you use screws on OSB?
You only need a #8 wood screw that is 1 1/2 inches long for 5/8 inch OSB or at most 2 inches long for 3/4 inch plywood. Also, deck screws have a coating that helps protect the screw from exterior exposure, which is not needed indoors. Deck screws will also cost more than the screws needed for your subflooring.
Can I use OSB instead of drywall?

What’s cheaper OSB or drywall?

How thick should OSB be for flooring?
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.
What is best subfloor material?
Plywood is considered the most popular material used for subflooring, it has been used since the 1950s and remains one of the top choices for contractors. Standard plywood works perfectly fine as a subflooring material, but the best option is ¾” tongue-and-groove plywood subflooring.
What is the best plywood for subfloor?
CDX plywood is the most popular type of traditional plywood. It’s made with a rough outer layer that typically grades C, D or X. Almost all subfloor plywood is some type of CDX. There’s no reason to buy high grade finished plywood for use as a subfloor if your just going to cover it up with finished flooring.
