The density of an object or development materials is a measure of its mass per unit volume. Several kinds of plywood can be found, and each has totally different properties suited to numerous purposes. OSB Sheathing is finest used for sub flooring, exterior partitions, and roof decking so it must be durable and dependable.

As you’ll see beneath, a 1/2″ thick, 4′ x 8′ feet sheet of OSB is approximately 31% heavier than softwood plywood however about 9% lighter than MDF sheets of the identical dimension. The process is similar for metric weights (i.e., kilograms), however you’ll want to make use of the load per square meter table above as an alternative. For reference, poplar plywood has a density of roughly 515 kg/m3, making these sheets a lot lighter overall, while normal MDF has an average density of round seven hundred kg/m3 resulting in a heavier sheet versus OSB. Another potential drawback of OSB’s increased weight is that it can be tougher to raise and maneuver, especially when coping with thicker full sheet sizes or working by your self.

## How Do You Calculate The Burden Of Osb?

Because of its elevated weight and density versus plywood, even a slight increase within the thickness of an OSB sheet can result in pretty sizeable weight will increase. Alternatively, a much quicker and simpler method to calculate the burden of a sheet of OSB is through the use of the straightforward OSB weight calculator under. The table below provides a abstract of approximate weights for OSB on a sq. meter basis. The weights have been calculated primarily based on a mean OSB density of roughly 39.ninety five lb/ft3 (converted from the typical 640 kg/m3 referenced here). For instance, when you multiply the sheet area of 2.9768m² by 11.fifty two kg/m² for an 18mm OSB sheet, you’ll get an approximate sheet weight of 34.29 kg. It’s price mentioning that it is attainable to search out OSB sheets with a decrease density than the average 39.95 lb/ft3, which reduces the overall weight of the sheet.

A metric 2440mm by 1220mm OSB sheet weighs from around eleven.5 kg to seventy two.5 kg . OSB is approximately 31% heavier than softwood plywood but about 9% lighter than MDF. The last step is to multiply the sheet area by the load per square foot (2.forty nine lbs/ft² for this example) to provide a sheet weight of roughly 79.sixty eight lbs. Next, you’ll have to know the weight per sq. foot, which taking a look at a 3/4″ OSB sheet for this instance is 2.49 lbs/ft² as per the reference desk above. A simple method to work out the burden of OSB is by using the burden per sq. foot reference table above (for imperial weights, i.e., lbs).

Whether you’re working with imperial or metric OSB, keep reading to find helpful reference tables of the weights of standard OSB sheet sizes and thicknesses. We’ve additionally included a helpful OSB calculator that will assist you work out the weight of custom sheet sizes too. Oriented strand board is usually heavier than plywood however lighter than MDF. A 1/2″ thick 4-foot by 8-foot sheet of OSB weighs around fifty three lbs, for example, versus about 40.5 lbs for a softwood plywood sheet and fifty eight lbs for an MDF sheet of the same dimension. The weight of a 4-ft x 8-ft OSB sheet ranges from about 26.5 lbs (1/4″ thick) to nearly one hundred twenty lbs (1-1/8″ thick).

Come to Sutherland Lumber Company if you would like guaranteed value and high quality OSB Sheathing.

### Eight 3/4 In (23/32 In) Osb Board Tongue And Groove

For readers outside the United States, or anybody working with metric sizing, the weight of a normal 2440mm by 1220mm OSB sheet ranges from round eleven.5 kg to virtually 72.5 kg . In this text, we’ll take an in-depth have a look at the weight of OSB, and we’ll also evaluate its weight to in style alternatives corresponding to plywood and MDF. We supply a wealth of sources that can assist you deal with any project, huge or small, from detailed how-to guides and reviews to instruments to assist you find high quality native house service providers. The thin strands of veneer are bonded in three cross-oriented (in different phrases, at 90-degrees to each other), giving the OSB wonderful dimensional stability and superior power versus MDF. Both the density and the amount subsequently impact the mass of an OSB sheet.

A contributing issue to OSB’s comparatively high density is its lack of void or knots that you’d find in cheaper plywood, with these defects reducing the density and weight of those boards. The first step is to work out the square foot space of the sheet you want to figure out the load of, with a 4-foot by 8-foot sheet having an space of 32 square toes, for instance . OSB sheets sometimes consist of 95% wooden fibers bonded collectively utilizing wax and artificial resins. Like OSB, plywood is another widespread engineered sheeting material that’s highly versatile.

## Osb Density – An Outline

OSB is often heavier than plywood, significantly versus softwood, hardwood, and premium baltic birch plywood variants. Pressure-treated plywood is one sort of plywood that tends to be heavier than OSB, however. The table under provides a summary of approximate weights for OSB on a sq. foot basis. For these within the United States, or anybody working with imperial sizing, the load of a regular 4′ x 8′ OSB sheet ranges from around 26.5 lbs (1/4″ thickness) to virtually 120 lbs (1-1/8″ thickness). Oriented strand board , or chipboard or flakeboard as it’s generally referred to, is a well-liked engineered sheet materials used for wall panels, subfloors, and roof sheathing. Oriented strand board, additionally generally called OSB and wafer board is a wood structural panel for roof and wall sheathing in addition to flooring.
