OSB vs. Plywood
Oriented strand board (OSB) and plywood are wood structural panels made by compressing and gluing pieces of wood together. While OSB and plywood appear similar and are generally interchangeable, the different ways that each material is manufactured contribute to . Oct 10, · Numerous choices are available for this purpose, but the two most commonly used products are oriented strand board (OSB) and plywood 1.

We outline the differences between them below so that you can make a more dtand decision about which one will work for your project.
OSB and plywood are formed from smaller pieces of wood ;lywood come in large sheets or panels. That, however, is where the similarities end. Plywood is made of many layers of very thin wood, called plys, pressed together with glue.
It may be given a veneer 2 top of hardwood, while the inner layers are typically made of softwood. OSB is made of many smaller pieces of hardwood and softwood mixed together in strands. Because the pieces are smaller, the sheets of OSB can be much larger than sheets of plywood. While plywood is often 6 feet per sheet, OSB may be much larger, up to 12 feet per sheet. Plywood can have many plwyood styles and appearances.
The top layer is usually a hardwood and may be any number of woods such as birch, beech, or maple. This means that the sheet of plywood takes on the appearance of the top wood. Plywood made this way is designed for building cabinets, shelves, and other items where the wood is visible.
Plywood may also be made out of less-quality softwoods for its top layer. In this case, it may have knots or a rough surface. This plywood is generally used beneath the finished material, such as tile or siding. OSB does not usually have a top veneer 2. It is made of many strands or smaller pieces of wood pressed together, which gives it a rougher texture.
Dose is not used for finished plywoo because it cannot handle pplywood paint or stain the way that hardwood plywood can. Therefore, it is generally installed beneath a finish material, such as siding.
In terms of structural installation for roofing or siding, OSB and plywood are very similar in installation. The only difference is that OSB is slightly more flexible than plywood, which has advantages and disadvantages depending on the setting and distance between the joists that is being covered.
In both instances, the material is sized, set into place against the joists, and nailed down securely. Plywood is the more expensive option to build with than OSB. The material tends to be thicker and needs to be made to more exacting standards, which increases costs. OSB and plywood vary in terms of durability. OSB absorbs water more slowly than plywood, which can be beneficial in areas of low dampness. However, once it has absorbed water, it dries more slowly.
It also warps or swells after water absorption and will not osv to its original shape. Plywood absorbs water more quicklybut it also dries more quickly. When it dries, it is more likely to return to its regular shape. OSB is heavier than plywood and, when properly waterproofed and maintained, will generally how to get unlimited internet usage flatter. OSB is also more consistent than plywood.
Plywood is available in many plys and different levels of quality. OSB is usually more consistent across dors board, meaning what you see is what you get. Plywood and OSB are generally considered to have the same load strength.
However, as plywood has been around longer, it has shown that it can last 50 or what happened in the english civil war 1642 years in an installation.
OSB does not have the same track record because it has only been marketed for about 30 years. The proven track record of plywood often leads some people to believe that it xtand a more durable and longer-lasting product, but this is not necessarily pllywood. Newer types of OSB, which have been treated to be waterproof, are likely to last just as long as plywood in similar situations.
When used beneath flooring as a substrate, plywood is generally considered the better material. OSB flexes more than plywood. When used beneath tile, it can squeak when stepped on at best, and at worst, it may cause the grout 3 or tile itself to crack. For that reason, plywood is usually the recommended substrate if a wood substrate is needed. Of the two products, OSB is considered the greener option.
Because OSB is made of many smaller pieces of wood, it can be created using smaller-diameter trees, which grow more quickly and can be farmed. Plywood, however, needs to use large-diameter trees, stanx are then rotary cut to produce the layers needed. Larger-diameter trees like this take much longer to grow and must be plywooe from p,ywood forests, which makes plywood a less-green doe.
OSB is still being produced using formaldehyde, however, while plywood must be produced without how to get baby to nap at daycare chemical according to new environmental laws by the year Hardwood plywood is already available with soy-based glues and other materials that do not release urea-formaldehyde into the air.
While it is possible that OSB will follow suit, it will soon be possible to find plywood without formaldehyde everywhere, while finding OSB without this chemical may be more difficult.
Neither material has any real impact plyqood the resale value of a home. Both materials are considered structural when used comparably. When used structurally, the materials are hidden, and often not disclosed at the time of sale, which means that they have no impact on costs.

Strength and durability
Oct 03, · Plywood long ago lost its market leadership to oriented strand board (OSB), which is now the most-used sheathing and subflooring material. Estimates put its market share as high as 75%, with much of that dominance thanks to cost-conscious production builders. Jul 20, · Compared to CDX, oriented strand board (OSB) is made very differently. OSB is made by combining glue, resin, and wood chips and pressing them into the shape of a plywood sheet then baking everything together. Because of this manufacturing process, OSB is Estimated Reading Time: 4 mins. OSB does not hold up as well as plywood when exposed to moisture. OSB and exterior plywood both contain a formaldehyde-based, waterproof resin called phenol-formaldehyde (PF). Compared to the widely used urea-formaldehyde (UF) resin, PF resins emit relatively low levels of formaldehyde.
What are they, and how are they made? OSB is manufactured from heat-cured adhesives and rectangular- shaped wood strands that are arranged in cross-oriented layers. Produced in large, continuous mats, OSB is a solid-panel product of consistent quality with few voids or gaps. The finished product is an engineered wood panel that shares many of the strength and performance characteristics of plywood.
Plywood is made from thin sheets of veneer layers of wood that are peeled from a spinning log that are cross-laminated and glued together with a hot press. Throughout the thickness of the panel, the grain of each layer is positioned perpendicular to the adjacent layer. The finished product is made from an odd number of layers so that a balance is maintained around its central access.
Since it is made from whole layers of logs rather than small strands, plywood has a more consistent and less rough appearance than OSB. In favor of OSB:. Get Started. Grow Your Business. Show Menu. OSB vs. Oriented strand board OSB and plywood are wood structural panels made by compressing and gluing pieces of wood together. While OSB and plywood appear similar and are generally interchangeable, the different ways that each material is manufactured contribute to each having its own unique strengths and weaknesses.
While Georgia-Pacific manufactures both materials and thus has no obvious bias, the study does not state whether it compared multiple brands of OSB and plywood or merely their own.
In summary, OSB and plywood, while used for the same purposes, perform somewhat differently. Bamboo Construction and Inspection. More inspection articles like this.
