- A viable alternative to plywood, this OSB Board is engineered to prevent any cupping, warping or splitting. The most common uses are for sheathing in walls, flooring, and roof decking. Engineered for load-bearing applications. No core voids, preventing cupping, warping or splitting.

How does a 4 by 8 foot and half inch thick thing of plywood weight? Depends what the ply value is,the number of layers glued together and density of a plywood. *A common rule of thumb is a 4x8 foot sheet of 1/4 fir plywood weighs 25 pounds. There are 32 square feet in a sheet, so a square foot of 1/4 fir plywood weighs about 0.78 pounds. Since 1/2 is twice as thick as 1/4, 1/2 fir plywood weighs twice as much, or 1.56 lbs, and 3/4 three times as much, or about 2.34 lbs. Fir plywood is common, but other species are available. Weight varies considerably between species of wood, so be aware the weight of plywood of different species can be different.

- Gather your materials, but be sure that you are using subflooring. This is similar to standard plywood, but has a tongue and groove. The thickness is a nominal 3/4 inch. Do not use OSB (oriented strand board). You will need to orient the sheet layout. You will want the grain of the plywood to be perpendicular to the joists.

Qualities of OSD and CDX Plywood OSD plywood. OSD plywood (which is also commonly known as OSB or oriented strand board) is produced by binding wood chips together with a mix of glue and resin. The mixture is then cast and baked to produce a plywood-like sheet. Because OSD does not use costly veneers it is as much as half the price of regular plywood.

Shipping Oversized Items with UPS, FedEx and USPS For each OS1 package, the billable weight is 30 pounds. A package is considered “Oversize 2” (OS2) when all of the following conditions apply: The package's combined length and girth exceeds 108 inches. The package's actual weight is less than 70 pounds. For each OS2 package, the billable weight is 70 pounds.

Plywood or OSB Panels: Which is better? Building codes consider OSB (Oriented Strand Board) and plywood interchangeable and refer to both as “structural wood panels” as both OSB and plywood panels are created when wood is glued and compressed to form a rigid panel.Despite the obvious similarities, there are some essential differences.hen OSB panels are created, thin wood strands are combined with adhesive and then hot-pressed into sheets. OSB’s strength comes from the fact that strands of wood are aligned in each layer and that each layer is perpendicular to the one below (they mimic plywood in this perpendicular layering).

"How much weight can a 3/4"" piece of plywood withstand?" I doubt you could find anything heavy enough to overload a 2x4 piece of 3/4 ply. The framework around the edges would break first. I would estimate aprox 1500 to 2000 lbs evenly spread. #3 Dec 3, 2002.

OSB vs. Plywood Outside of North America, OSB is not commonly used in construction. In 2005, the combined production of OSB in Europe and Latin America was just 3.5 billion square feet – less than seven times as much as was produced in North America that year.

What is better for a roof, plywood or OSB? You are right on both counts DAO1, OSB is cheaper, but not as moisture stable as plywood. Looks like they are using maybe 30 to 40% OSB, strictly as a cost savings. If they were building top quality, they would be using Advent-Tec T&G roof sheathing, which is about twice the cost of OSB and 25% more than good CDX.lywood grasps the nails holding flashing, the finished roofing like asphalt shingles, or the like, better, especially long-term, than OSB which tends to soften more quickly with moisture cycles over the years.

- OSB is an engineered wood product that is made with flakes or large chips of wood. The panels are formed from layers or plies glued together with their strands at ninety-degree angles to one another. The cross orientation of the layers adds strength to the panels and makes OSB well suited for use as a structure board.

- Being an engineered material, OSB may be custom manufactured according to specifications for different size, thickness, density, texture and strength. OSB is a performance-rated material and is popular with architects and contractors.

why use OSB instead of plywood? Both plywood and osb come in various thickness. If your 1x8 is actually 3/4 thick - use 3/4 osb/ply. If it is a full 1 thick you could use 2 layers of 1/2. The only asbestos siding I'm familiar with are stiff brittle shingles nailed up for siding.

Contents: OSB vs Plywood 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.s 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.

- OSB boasts a more consistent density. While a sheet of plywood might be 5 to 7 plies thick, a sheet of OSB is made from as many as 50 strand layers packed and compressed into the same thickness. There's no equivalent of the weak spots that can be left in plywood when knotholes in adjacent plies overlap.

why use OSB instead of plywood? In my opinion, OSB is about 1/2 the cost and also has lines on the rough side to line up w/ your studs or rafters, either 16 or 24 OC. On roof sheathing, the rough surface gives better traction. Keep in mind that OSB have directional strength and need to be installs w/ the 8' direction, perpendicular to the rafters.

Choosing Between Oriented Strandboard and Plywood Market Rap. Osb has earned its reputation as a low-cost substitute for plywood. In fact, recent price quotes from Denver, Boston and Atlanta put 7/16-inch osb $3.00 to as much as $5.00 per sheet lower than 1/2-inch cdx plywood.he weights of osb and plywood are similar: 7/16-inch osb and 1/2-inch plywood weigh in at 46 and 48 pounds. However, 3/4-inch Sturd-I-Floor plywood weighs 70 pounds, 10 pounds less than its osb counterpart.

- To be sure, there is no difference between OSB and plywood as a structural panel, says APA - The Engineered Wood Association. The Tacoma, Wash.-based group is a nonprofit trade association that represents U.S. and Canadian manufacturers of plywood and OSB as well as other structural engineered wood products.

Proper Subflooring for Wood on Second Floor Thickness Requirements. OSB doesn't hold nails as well as plywood, so an OSB subfloor needs to be thicker. If the joists are spaced 16 inches on centers or less, the minimum required thicknesses are 5/8 inches for plywood and 23/32 inches for OSB.hether you're installing a hardwood floor on the first or second floor of a building, you need a solid subfloor that won't sag and that will hold nails. The two materials that most builders use are plywood and oriented strand board (OSB).

- square-edge OSB 3 panels are recommended for wall sheathing applications. OSB 3 has a high structural racking strength - ensuring stability in transport and erection and the inherent strength required in the completed timber frame structure. Possible expansion should be allowed for by providing a 3mm gap between adjacent panels and between the panel and any abutment. This gap should not be less than 10mm wide.
