Why is plywood so heavy?
Plywood uses at least three layers of wood laid perpendicular to one another and bound with a strong wood glue. The faces of plywood are usually a higher grade of wood than the interior layer(s); however, the density of the plywood is consistent across the cross section of the board.

How much does a pack of plywood weigh?
Engineers have rounded-off weight calculations for plywood to square foot calculations, and have decided that, for engineering purposes, a generic square foot of 3/4-inch-thick hardwood plywood weighs 2.3 pounds. A 4-by-8 sheet of plywood equals 32 square feet, so 32 times 2.3, is just over 70 pounds per sheet.
What is the density of structural plywood?
Structural plywood requires a very higher compression ratio compared with non-structural plywood. Non-structural eucalyptus plywood density is 580 kgs/m3. Structural eucalyptus plywood density can be as high as 600 kgs/m3.
How much does birch plywood weigh?
Birch Plywood weigh 650-700 kgs per cubic meter. Plywood with the lightest weight is made with a Benuang core. Its scientific name is Octomeles sumatrana. This is an Indonesian wood species. It also grows in Papua New Guinea with a local name Erima.
Is WBP phenolic glue heavier than normal urea glue?
WBP Phenolic glue is heavier than normal urea glue. For example, poplar plywood with urea glue density is 520 kgs/m3. Poplar plywood with phenolic glue density is 530 kgs/m3. Some manufacturers spread more glue on the veneers to increase strength. This practice will also increase the weight of plywood sheets.
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
If a little math doesn’t intimidate you, then calculating plywood weight yourself isn’t that difficult once you know what values to use. To determine the total weight, you need to know the weight per square foot of the plywood.
What is the importance of knowing the weight of plywood?
After you buy plywood, you’ll need to move it to where it is required, and it will also be moved around the area of application depending on how it will be used. You need to know both the maximum load capacity of your method of transport and the weight of the plywood.
Main factors influencing the weight of plywood
Two main types of trees are cut into logs for plywood sheet production: hardwood and softwood trees. Hardwood trees are heavier than softwood trees. For example, plywood made from mahogany or oak is heavier than plywood made from birch. Even when dried and the moisture tubes are empty, the denser wood has more air tubes, increasing weight.
Calculating the weight of a single sheet of plywood
To know the weight of an entire board of plywood, you’ll need to calculate the weight of one single sheet. Measuring the whole plywood board is difficult and almost impossible if you have numerous boards of plywood. Measuring the weight of plywood by starting with calculating the weight of a single sheet also provides a more estimated figure.
Calculating the weight of one sheet of plywood
To get the weight of one single sheet of plywood thicker or thinner than the ones listed, you can use the cross-multiplication method if both plywood boards are of the same size.
Final thoughts
If you are going to use plywood in any form of construction, whether large or small, you need to know the weight. For smaller projects such as coffee tables and bookshelves, knowing the weight may not be necessary. You can test the plywood by yourself and see if it will hold but ensure you check for any damages that may be a sign of weakness.
What are the different types of plywood?
Usually 4 kinds of timber species are used to manufacture the cores of plywood ( film faced plywood ) , i.e. birch, hardwood, pine and poplar. The density of different plywood is listed as follows: Sometimes, buyers order combi core plywood , such as combined poplar/hardwood, combined birch/poplar and so on .
Is plywood higher density?
PLYWOOD DENSITY. The Density of Plywood is higher than the density of the timber species used to manufacture the products . The face/back veneers of plywood weight practically much less than the core veneers. So the density of plywood is mainly depended on the timer species of the core veneers .
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.
