What 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. However, nail-holding ability controls performance in shear wall applications.

What is OSB wood used for?

Applications. 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.

How long will OSB last outside?

OSB, which is protected from the elements or sealed with paint or stain, can last for decades. Some exterior OSB wall panels are even guaranteed for 50 years.

Is OSB wood waterproof?

OSB is strong and water-resistant. This type of construction makes OSB is an incredibly strong material. In many instances, it is rated for load bearing applications (depending on the OSB grade). This type of board is an excellent material for use in waterproofing systems, be they roof, sub-floor or wall.

What is stronger plywood or MDF?

Advantages of plywood Made from multiple layers of wood veneer, plywood is a very strong material to work with. It won’t soak up water and liquids as quickly or easily as MDF does so it’s less susceptible to water damage. Because it carries a grain, plywood is stainable.

Is OSB ruined if it gets wet?

OSB won’t be completely destroyed by water, unlike MDF or similar interior laminate materials; however, like any wood product, it will swell and shrink as it absorbs and releases water, so you should typically avoid more than casual contact with water.

How long will OSB last?

Panels protected by shingles or steel roofing, or behind siding or brick veneer will normally last as long as the structure stands. OSB, which is protected from the elements or sealed with paint or stain, can last for decades. Some exterior OSB wall panels are even guaranteed for 50 years.
