What's the difference between OSB and CDX plywood?

OSB is much more waterproof than plywood and CDX plywood. The glue and resin that is mixed in with the wood chips makes it much less permeable, so OSB holds up longer in harsher conditions. That is why OSB is sometimes used to secure houses when a hurricane draws near.

What thickness plywood should I use for flooring?

Some experts suggest that 15/32-inch plywood should be standard if the underlying floor joists are spaced 16 inches apart or less, but slightly thicker 3/4-inch plywood should be used for joists spaced further apart.

Why Is It Important to Know the Weight of Plywood?

Plywood is used for roof sheathing as well as subfloors. Both of these structures are supported by structural framing and that framing has limits on how much weight it can hold. Applying too much weight to framing can cause serious structural problems.

What Factors Impact Plywood Weight?

There are a surprising number of factors that impact plywood weight ranging from the obvious, thickness and size, to the not so obvious, wood species and density. Understanding how these factors impact the overall weight of a sheet of plywood is crucial to calculate its weight.

How Much Does a Sheet of Plywood Weight

Understanding how much the most commonly-used sizes of standard plywood weighs is helpful when determining the overall weight of a floor or roof or planning logistics for transporting the wood from store to site.

Weight of Pressure Treated Plywood

As discussed in detail above, the liquid chemicals used to protect this type of plywood from the elements significantly increase weight. Of course, treated plywood, like all treated lumber, dries over time and becomes lighter.

How Much Does Baltic Birch Plywood Weigh?

This high-quality type of plywood, produced in Russia, is renowned for its strength. Baltic plywood is made of all plywood with no fillers, making it very strong even at thinner thicknesses. This makes it suitable for durable furniture and even skateboards. Because it is denser than other types of plywood, it weighs more.

How Much Does Marine Grade Plywood Weigh?

While marine plywood is not waterproof, it does use higher quality outer plies that protect the wood from the elements. The glue used to make standard plywood is prone to coming apart in humid coastal environments. Marine-grade plywood uses a higher quality glue that better resists moisture.

Weight of Plywood per Square Foot

Which is denser, plywood or MDF?

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.

Why is hardwood lumber heavier than softwood?

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.

Is plywood a sheet?

Other Sheet Materials. Plywood might not actually be plywood, but actually an engineered product. Lots of cabinets and furniture makers rely on a particle board or MDF -- medium-density-fiberboard -- and it's heavier than plywood. With a hardwood veneer, MDF has a dense particle board core, and looks just like ordinary plywood.

Is MDF plywood or plywood?

With a hardwood veneer, MDF has a dense particle board core, and looks just like ordinary plywood. It's much heavier, tipping the scales at between 90 and 100 pounds for a single sheet. If you're not sure if it's MDF or not, examine the side. If you see layers it's plywood.

Is fir plywood heavier than maple?

Hardwood is more dense than softwood, so a sheet of fir plywood will typically weigh less than a sheet of maple. If you're not sure what you're dealing with, it's always better to estimate on the heavy side, especially when loading multiple pieces on a pickup truck, for example, or estimating the weight for a floor.

Is Plywood Ideal for Weight-Bearing Applications?

If you are wondering whether or not plywood is ideal for weight-bearing applications, what you need to know here is that it really does depend on the size, the thickness, and the type of plywood in question. There are many different types of plywood out there, dozens in fact, and they all have different strengths.

Summary

Now that you know exactly how to calculate the load-bearing capacity of the specific piece of plywood as well as the various factors that affect how much weight plywood can bear, you can now choose the right kind of plywood for your specific application.

How much weight can plywood support?

But just how strong is plywood? How much weight can plywood actually support? The thickness is the most important part. A 12-by-36-inch piece of plywood that is ¼-inch thick will only support about 5 pounds before it starts to bend. But a 12-by-36-inch piece of ¾-inch plywood can support 50 pounds easily.

What is the thickness of plywood?

The thicker that the plywood is, the stronger that it will be. That is why one of the most commonly used thicknesses for plywood is ¾-inch. When it comes to heavy-duty construction projects, 1-inch-thick plywood is typically the plywood of choice. There are also pieces that have tongue and groove patterns.

Why is glue used on plywood?

The glue keeps the plywood from taking on moisture. Moisture is what can cause the layers within plywood to separate, weakening the plywood over time. Should the manufacturer use inferior glue on its softwood plywood, then it won’t be as strong as the hardwood plywood.

Why do they use exterior glue on plywood?

To overcome that weakness, some manufacturers will make use of exterior glue to give adhesion to the layers. The exterior glue, when used on softwood plywood, can even make that softwood plywood stronger than its hardwood counterpart with some time. The glue keeps the plywood from taking on moisture.

How many layers of plywood is moderate strength?

Moderate strength plywood will have anywhere between 4 and 7 layers to it. When it comes to moderate strength plywood, you can also use it for nearly any project that you can think of outside of industrial projects. The strongest plywood that you can find has more than 7 layers to it.

Why is plywood so strong?

The reason that it is so strong is because of how it is constructed. There are several layers of varying materials that have been bonded together under high pressures. These layers are then glued on top of one another. Plywood also uses alternating grain patterns.

How to tell the strength of plywood?

A good way to determine the strength of the plywood being used is to look at the number of layers associate with that plywood. The cool thing is that you can count each of the layers by focusing on the edge of any of the pieces of plywood that you use.
