What is oriented strand board 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.

Is OSB cheaper than plywood?

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 oriented strand board 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 oriented strand board good for roofing?

Both the National Roofing Contractors Association and the Asphalt Roofing Manufacturers Association recommend the use of OSB for roof sheathing, as long as it bears the approval stamp of the APA - Engineered Wood Association.

Can oriented strand board be painted?

The Engineered Wood Association (known as the APA) acknowledges that you can successfully paint "Exposure 1" OSB. ... Also, OSB's strands' prominently visible nature will likely show through on one coat of paint, so filler and heavy primer are probably required to remove some of the texture of the wood.

Is OSB stronger than 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.

What are the disadvantages of OSB?

Prone to swelling edges and telegraphing. “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.

Why is OSB plywood so expensive?

So what does this mean for prices? An oligopoly has few producers but many buyers. When industry production capacity exceeds demand, OSB pricing resembles a competitive market. The few producers will compete with each other for business in order to keep their enormous, expensive, manufacturing plants producing 24/7.

Is it OK for OSB board to get wet?

4 Answers. 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.

Is OSB board stronger than 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.

Which 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.

Can you put metal roofing directly on plywood?

Metal roofing should not be installed directly over the top of bare plywood. You do not have to install roofing shingles or other roofing material, but a felt sheet over the plywood is the bare minimum. ... Even without heavy rain, humidity can build up between the metal roofing and the plywood and ruin the wood.

Will rain hurt OSB board?

Your framing lumber and the oriented strand board (OSB) are going to be fine. The glues used to make OSB are water-resistant because the manufacturers know that virtually no one can build a home that won't get wet before the roof and siding is applied.

Which is better 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.

Is OSB more water resistant than plywood?

OSB takes longer to get wet than plywood but also takes longer to dry out. When used as a roof sheathing, this tendency to hold moisture means it can degrade faster than plywood when exposed to chronic leaks. ... Swollen edges have been known to telegraph visible ridges called “ghost lines” through asphalt roof shingles.

Which is better OSB or MDF?

OSB is considered to be stronger than MDF. OSB is suitable for structural projects and withstands water, moisture, and weather conditions better than MDF. However, MDF is more versatile and easy to work with than OSB and preferred for projects requiring a smooth finish.

What is a good substitute for OSB?

Most builders are so comfortable with OSB wall sheathing that they never consider using an alternative material. In fact, a wide range of materials can be used to sheathe a wood-framed wall. In addition to OSB, builders can choose plywood, fiberboard, rigid foam, diagonal boards, and fiberglass-faced gypsum panels.

Can plywood be waterproofed?

Can You Waterproof Plywood? Plywood is very receptive to waterproofing material. The smooth finish is still porous enough on a micro level that the plywood will easily bond with sealers and paints. This means plywood can still be used outdoors and in marine environments.

Is OSB harder than plywood?

Osb is stronger than plywood in shear. ... 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. So both products perform equally well as shear-wall components.

Can you put metal roofing directly on rafters?

Metal roofing can be installed directly on open rafters. ... The vapor barrier built into such insulation helps to minimize the amount of condensation that drips down from the roof, and the insulation itself can help to keep the interior of the building at a comfortable temperature.
