Is OSB as strong as plywood?
OSB and plywood offer similar (and sufficient) performance in terms of strength and functionality, though plywood is about 7% stronger.
How much does 7/16 plywood weigh?
The weights of osb and plywood are similar: 7/16-inch osb and 1/2-inch plywood weigh in at 46 and 48 pounds.
Is plywood heavier than pine?
Because birch plywood is made of dense hardwood, it does tend to be a good deal heavier than pine plywood. Yes, this extra weight and durability are great for a number of purposes, albeit not for making lightweight wooden constructions.
What holds screws better OSB or plywood?
Plywood and OSB: Screw withdrawal or holding ability. Group 1 plywood, made from the strongest species of wood such as Southern Yellow Pine, holds screws better than OSB.
Is OSB load bearing?
Due to its inherent strength (see below), OSB is particularly suitable for load-bearing applications in construction but it also has a wide range of other applications.
Which is more water resistant OSB or 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.
Why is 7/16 OSB so expensive?
Increasing OSB prices are due to demand over supply, increasing construction starts, and several natural disasters. As contractors, architects, and building owners struggle to offset the high OSB prices, an excellent alternative sheathing product to consider is Barricade Thermo-Brace.
Is 7/16 OSB OK for roofing?
OSB is the most-used sheathing material for new roofs and roof replacements. You can use 7/16-inch thick OSB sheets without support for areas where the snow load is 30 pounds per square foot because it’s durable and maintains building integrity much longer than other sizes.
Why is OSB still 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.
Which 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 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.
Can you use 7/16 OSB subfloor?
Oriented strand board, or OSB, is a wood structural panel that can also be used for flooring. It is made from shredded strands of wood pressed together with wax and a special adhesive, then hot pressed into a panel with up to 50 layers of strands. OSB can be used for subfloors, although it is not as common as CDX.
What is the weight of a 4×8 sheet of OSB?
A typical 4′ x 8′ sheet of 1/2-inch OSB weighs around 54 lbs.
Is OSB lighter than MDF?
MDF can be extremely heavy because of its high density. It is harder but not as strong as OSB. It crumbles when exposed to water or moisture. If you are cutting several panels, you will notice the blades getting duller.
What wood is lighter than plywood?
Particle Board
The most affordable alternatives to plywood are undoubtedly particle boards. Made by condensing wood particles, particle boards are also much more lightweight than plywood and MDF. Its slick and smooth finish makes it a great flooring material.
What is the lightest wood?
- Redwood – It’s one of the lightest and most durable woods used for building. …
- Cedar – At just 19.7 to 23 pounds per square foot (dry) Cedar is one of the lightest woods. …
- Cypress – Like Cedar and Redwood Cypress is a lightweight softwood that is durable and resistant to water damage.

Stacks of 4’ x 8’ softwood plywood panels, 15/32-inch thick. Each sheet weighs about 40 pounds, so each one of those stacks weighs almost a ton and a half.
Plywood and OSB Weight Factors
The weight of plywood and OSB depends partly on the amount and the type of the adhesives, primers, and sealants used to make it. Different types of plywood will use different amounts of these substances, and they are very heavy relative to wood.
Another weight factor is the wood species used to make the panel. Different wood species have naturally different densities, and this can make a big difference in the weight of the finished product.
These variations can result in weight differences of up to 20% for plywood and OSB panels with the exact same dimensions and product description from one manufacturer to the next, or even for different batches of the same product from the same manufacturer.
What is Plywood Made of?
Plywood is composed of approximately 92% – 97% wood, with the remainder made up by primers, sealants, and adhesives such as phenol formaldehyde resin.
Other engineered wood panel types, such as particle board or OSB, contain a much higher percentage of adhesive resin, and since these resins are heavier than wood, these panels tend to be significantly heavier than plywood.
Weights of Different Types of Plywood
What is the APA Standard Weight for Plywood?
APA Plywood Standard: The Engineered Wood Association (formerly the American Plywood Association) provides standard notional plywood weights for use in determining expected dead loads when performing structural engineering calculations.
Softwood plywood is typically used as structural plywood (roof decking, sheathing, flooring).
The APA Standard weights are not the weights of actual products and tend to be somewhat heavier than the weights of any real softwood plywood you will find.
A 4’ x 8’ sheet of 1/2-inch APA Standard Plywood would weigh 48 lbs.
How Much Does Baltic Birch Plywood Weigh?
Baltic Birch Plywood: This is a high-quality plywood produced in Russia and other areas around the Baltic Sea.
It is made up entirely of birch wood, so unlike some other hardwood plywood, it does not use softwood for the inner plies, and the inner plies are void-free, increasing its stability. Used mostly for furniture-making and cabinetry.
A typical 4’ x 8’ sheet of 1/2-inch Baltic Birch Plywood weighs around 55 lbs.
See Baltic Birch Plywood at the Home Depot.
How Much Does Hardwood Plywood Weigh?
Hardwood Plywood: At least the front and back veneers (outer plies) of this plywood will be made of a hardwood species such as maple or oak.
Although the inner plies may also be hardwood, more often they will be made of a cheaper softwood species. The hardwood veneers improve strength, stability, and impact-resistance, and it’s commonly used in applications where these qualities are desired, like flooring or wall paneling.
A typical 4’ x 8’ sheet of 1/2-inch Hardwood Plywood weighs around 48 lbs.
See Hardwood Plywood at the Home Depot.
How Much Does Marine Plywood Weigh?
Marine Plywood: Despite its name, this is not a waterproof plywood. It is manufactured using water-resistant adhesive and very high quality outer plies which help prevent moisture from penetrating the panel.
It is designed to be used where the material will be subjected to higher-than-normal amounts of moisture, such as in coastal environments.
A typical 4’ x 8’ sheet of 1/2-inch Marine Plywood weighs around 51 lbs.
How Much Does Pressure-Treated Plywood Weigh?
Pressure-Treated Plywood: This is generally a softwood plywood that has been pressure-treated to help it resist decay caused by fungus, insects, and other organisms.
Southern yellow pine is particularly well-suited for pressure treating, and most pressure-treated plywood is made from southern yellow pine. Special waterproof adhesives are used so that the plywood can withstand the pressure-treating process without falling apart.
Because of the adhesive and the fact that southern yellow pine is much heavier than other wood species used in construction, pressure-treated plywood tends to be a heavy plywood, even after drying out after the pressure-treating process. Before drying out, of course, it can be much, much heavier.
A typical 4’ x 8’ sheet of 1/2-inch Pressure-Treated Plywood weighs around 60 lbs.
See Pressure-Treated Plywood at the Home Depot.
How Much Does Softwood Plywood Weigh?
Softwood Plywood: This is the type of plywood most commonly used in construction.
Structural plywood is usually softwood plywood. It is used for roof sheathing, wall sheathing, subfloors, and more.
Softwood plywood comes from coniferous trees, primarily fir, pine, or spruce. It is generally the lightest type of wood panel, due to the light weight of the wood species used, the (relatively) low amount of adhesive used in the manufacturing process, and the presence of unfilled voids within the inner plies.
It is normally the cheapest plywood. CDX plywood is a grade of softwood plywood.
A typical 4’ x 8’ sheet of 1/2-inch Softwood Plywood weighs around 43 lbs.
See Softwood Plywood at the Home Depot.
How Much Does MDF Weigh?
MDF: Medium Density Fiberboard is produced from wood scraps left over from other wood product manufacturing activities.
This waste wood can be either hardwood or softwood. The scraps are broken down into very small wood fibers, which are combined with wax and adhesive resin to form the MDF panels.
MDF does not handle moisture well, and is normally only used for interior applications, such as flooring or furniture.
Because of the high resin content, it tends to be one of the heaviest engineered wood panels.
A typical 4’ x 8’ sheet of 1/2-inch MDF weighs around 69 lbs.
See MDF at the Home Depot.
How Much does MDO Weigh?
MDO: Medium Density Overlay is a type of exterior plywood specifically designed to be painted easily. Due to its extremely smooth surface, it holds paint better, and looks better after being painted, than other types of engineered wood panels.
The wood plies in MDO panels are typically softwood, and a thick, smooth layer (the overlay) of a highly water-resistant resin is applied to one or both sides of the panel.
A typical 4’ x 8’ sheet of 1/2-inch MDO weighs around 48 lbs.
How Much Does Particle Board Weigh?
Particle Board: The product generally known as “particle board” is similar to MDF.
It is made with similar manufacturing techniques, but the end product is cheaper, weaker, and of lower density. It is also called LDF (low density fiberboard).
A typical 4’ x 8’ sheet of 1/2-inch Particle Board weighs around 66 lbs.
How Much Does OSB Weigh?
OSB: Oriented Strand Board is plywood’s biggest competitor as a structural wood panel in North America.
In large-scale commercial construction, it has largely replaced softwood plywood in wall sheathing, roof sheathing, and subflooring applications. This, of course, is due to the fact that a sheet of OSB costs about 20% less than the equivalent sheet of plywood.
OSB is made by breaking down wood into small strips, or “strands”, up to 6 inches long, combining these strands with wax and adhesive resin under pressure and heat to form layers.
The strands in each layer are all generally “oriented” in the same direction. These layers are combined to form OSB panels of the desired panel thickness.
The wood strands in the outer layers are oriented one way, and the strands in the interior layers are oriented the other way, which increases panel strength.
OSB is manufactured in a slightly different range of thicknesses than plywood.
A typical 4′ x 8′ sheet of 1/2-inch OSB weighs around 54 lbs.
See OSB at the Home Depot.

The values given in the following tables are meant to provide a general idea of typical engineered wood panel weights, and should not be used if precise values are needed for critical engineering calculations.
When precision is necessary, always refer to the specification sheet for the actual, specific product you intend to use, or contact the technical department of the panel manufacturer.
About Our Plywood Weight Charts
The following tables provide typical weights (dead load, self-weight) for plywood, OSB, and other engineered wood panels.
We provide metric and US standard weights for whole standard sheets of various common thicknesses, as well as weights per square foot, and weights per square meter.
The weights we give were calculated using the product data sheets or manufacturer specifications of actual, specific wood panel products, and in most cases our weights are the average of product weights from more than one manufacturer.
How Much Does Plywood Weigh?
The actual weight of plywood varies by product and manufacturer which can make it challenging to predict the weight perfectly. On average, a 4′ x 8′ sheet of 3/4″ softwood plywood weighs about 61 pounds. Read on to learn more about what impacts the weight and find the weight for different varieties and thicknesses of plywood.
What Affects the Weight of Plywood
A few factors impact the weight of plywood. The precise thickness of the panel is a major factor in the weight. Not all plywood is the nominal thickness after drying. Learn more about the actual thickness of plywood.
In addition to thickness, the type of plywood is a major factor in how much it weighs. Different species of woods have varying densities. For example, hardwood lumber weighs more than softwood lumber due to higher densities. Calculate the weight of different species of lumber using our lumber weight calculator.
Different types of plywood also have varying amounts of glues and resins, which affect the weight significantly. In addition to using different amounts of glues and resins, different types of resin vary in weight. There are some varieties of plywood that use special resin to reduce the weight, for instance, lightweight plywood products.
Different grades of plywood may also have more or fewer voids than others, which might slightly impact the weight. A panel made up mostly of particles and glue(MDF) will be much denser than plywood with many voids and less glue.

OSB vs Plywood – Difference and Comparison
While OSB (Oriented Strand Board) is generally cheaper than plywood , it is heavier and not as stiff as plywood and can result in soft squeaky floors under weight. The biggest complaint against OSB is that it doesn’t handle moisture very well so it is more suited for indoor use. Moisture also affects the strength of plywood ; so while exterior glued plywood can be used outdoors, it works best when moisture content remains low. OSB has over 70% market share for structural panels.

Strength and durability
Both plywood and oriented strand board (OSB) are equal in strength and durability. This comes as a surprise to many consumers because OSB looks simply as if lots of pieces of wood were glued together. Building codes recognize both plywood and OSB to be alike in their properties and use the phrase “wood structural panel” to describe them.
However, plywood subfloors are stiffer than OSB by about 10%. As a result, OSB floors are more likely to
squeak due to floor movement
cause hard floor surfaces to crack (such as tile)
result in soft, spongy floors
Cost of Plywood vs OSB
OSB is cheaper than plywood by about $3 to $5 per panel. For a typical 2,400 sq. ft. home, OSB is about $700 less expensive compared with plywood if used as the subfloor, sheathing, and roof decking.[1]
Usage
Both plywood and OSB are used for sheathing roofs, walls and subfloors. They work equally well for these uses, are just as easy to drill into and have equivalent ability to hold nails. However, OSB is generally considered less resistant to water (it swells in thickness when exposed to moisture) and some people prefer plywood for roofs and subfloors. The Miami-Dade County Board of County Commissioners banned OSB for use as roof sheathing after Hurricane Andrew destroyed thousands of homes in 1992.[2]
Some builders find OSB panels easier to use because they have pre-printed gridlines to facilitate measuring, marking, cutting, and fastening. Plywood manufacturers have also introduced grid-marked sheathing, and it is advisable to use that because it speeds installation.
OSB panels can be manufactured in lengths up to 16 feet (or sometimes even higher), while plywood is generally limited to 8 to 10 feet. So OSB is preferable for applications where longer or wider panels are required.
It should be noted that some OSB manufacturers use advanced technology to make higher quality OSB panels, including more moisture-resistant products. These are more expensive than traditional oriented strandboards but may well be worth the price given their durability and performance.
Popularity
As OSB is cheaper than plywood and has the strength and durability of plywood it is becoming more widely used than plywood. OSB was introduced in the 1970s and steadily gained market share from plywood, surpassing plywood in production in 2000. Today OSB has 70-75% market share and plywood has about 25% share.
Pros and Cons
Advantages of Plywood
Plywood offers all the inherent advantages of the parent wood plus enhanced properties in its laminated structure.
Being a wood based material, plywood has the ability to accommodate the occasional short-term overload, up to twice the design load. This is useful where seismic activity or cyclonic winds can occur. This property is also effective when used as construction flooring or as concrete formwork. Plywood’s laminated structure distributes loads from impact over a larger area on the opposite face, which effectively reduces the tensile stress.
The cross laminated construction of plywood ensures that plywood sheets remain relatively stable under changes of temperature and moisture. This is especially important in flooring and formwork construction where moisture exposure is very likely.
The high strength and stiffness to weight ratios make plywood very cost effective to use in structural applications such as flooring, shear walls, formwork and webbed beams.
The panel shear of plywood is nearly double that of solid timber due its cross laminated structure. This makes plywood a highly effective material to use in gussets for portal frames, webs of fabricated beams and as bracing panels.
Plywood does not corrode and can be used in chemical works and cooling towers as a cost-effective, durable material when preservative treated.
Advantages of OSB
Similar to plywood but more uniform and cheaper.
Aspen and Poplar tree species are used. But can also be manufactured from fast growing species and smaller trees.
It has more decay resistance than plywood.
Shear value through its thickness is twice as that of plywood and hence is the choice for webs of wooden I-joists.
There are no soft spots as two knot holes overlap. Hence, can be nailed at the edges without worrying about them.
It is manufactured as larger sheets and hence a single sheet can be used to sheath a wall and the joists below.
Disadvantages
Plywood is porous and is susceptible to damage when exposed to water for longer time. OSB is not water resistant and hence cannot be used for exterior projects.
Environmental factors
OSB can be made from small diameter trees such as Poplar that can be farmed but plywood requires larger diameter trees from old-growth forests. On the other hand, OSB releases more formaldehyde (which is a carcinogen that is off-gased) than plywood.
Manufacturing
Oriented Strand Board (OSB) is manufactured in wide mats that are formed from cross-oriented layers of thin, rectangular wooden strips. These layers are bonded using wax and resin. The layers are formed by shredding wood into strips. The strips are sifted and oriented in belts or wire cauls. The mat is formed in a forming line. The layers can vary in thickness to give different finished products.
Plywood is made from good log called peelers. Thin layers are peeled from the wood by rotating it along its horizontal axis. The sheets of veneer thus obtained are cut to the desired dimensions, dried, patched, glued together and then baked in a press at 140 °C (284 °F) and 1.9 MPa (280 psi) to form a plywood panel.
