However, due to the way the wafers are made in OSB panels, there is a substantially greater amount of end grain exposure present. Commodity OSB uses glues and a process that permits the panel to soak up moisture. For example, dimensional lumber such as a 2 x 4 will absorb moisture more readily through the two ends than through the four faces. OSB is made of many smaller pieces of hardwood and softwood mixed together in strands. Regarding OSB SubflooringWhen used as a subfloor, either product will work for many flooring surfaces, especially carpet where there will be no noticeable difference.

OSB is a structural wood sheathing panel that is primarily made up of hardwoods (aspen, birch and popular) and softwoods (lodgepole pine and southern pine) that are combined with synthetic resin, liquid wax and other additives. This is due to changes that occur to the physical properties of the wood fibers as a result of the manufacturing process. Natural wood tends to absorb moisture more rapidly through the end grain than through the face grain. Both plywood and OSB subfloor should range in thickness from 19/32″ to 1 1/8″. For tile flooring, this can cause bending … Additional mats are then created by placing new wafers in opposing directions to give the panel its structural rigidity. We also found a significant difference in the performance between the different OSB options DOWNLOAD FREE PRINTABLE PDF BELOW Buy Plywood vs. OSB Subfloor Comparison BOG can occur due to field conditions present during the delivery, storage, installation, and even normal time delays during the course of construction.

OSB is created using 3”-4” strands of wood which are then pressed together using glue. 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.

Because the pieces are smaller, the sheets of OSB can be much larger than sheets of plywood. Most of time if the impact fall between the joists over the clear chipboard this will break it. They also both involve layers of material instead of being solid pieces of wood like dimensional lumber. While the International Building Code defines both OSB and plywood as “wood structural panels” and the American Plywood Association (APA) describes them to be structurally equal, it is important to understand that each product is manufactured differently and therefore perform better under varying circumstances. OSB panels can be produced from both barked and debarked trees. The National Tile Contractors Association and the Resilient Floor Covering Institute both recommend plywood for subflooring and underlayment, because it doesn’t have the risk of swollen edges that OSB does. The typical OSB manufacturing process begins with the harvesting of smaller diameter trees than those typically selected for dimensional lumber. OSB is more common now than plywood, less expensive. This is due to two main concerns: Exposed OSB on a job site following a rainstorm. Unfortunately, an OSB is less resistant to water compared to plywood. As mentioned previously, OSB has acquired a negative reputation over the years, as builders have reported swelling of their sheathing panels, a decline in structural strength and the presence of BOG when exposed to moisture. A long lasting solid hardwood floor is heavily influenced by the quality of the sub-floor.When it comes to types of sub-floors there is a wide range but we will focus on the two most often used in modern buildings.

OSB exposed during construction must be allowed to dry (especially before installing sensitive finish materials such as hardwood flooring). Since OSB maintains such a low moisture content, it will invite excess moisture which in turn could saturate the product. We also offer Quality Assurance inspections in which we can inspect to verify the OSB sheathing is not installed in conditions that would lead to premature failure. While some exposure may be unavoidable due to typical construction practices, the building should be dried-in as soon as possible to prevent extended exposure of all wood products and other moisture sensitive materials. Plywood long ago lost its market leadership to oriented strand board (OSB), which is now the most-used sheathing and subflooring material. CDX plywood is created by bundling layers of wood together.

While the feud between plywood and OSB continues, it is important that builders are aware of the potential pitfalls of construction, and steps that can be taken to avoid risk. Although some finished flooring materials can be laid directly on the subfloor, it is often recommended to add another thin layer of underlayment between the subfloor and finished floor.

While they are both made by compressing homogeneous mixtures of wood waste-product, OSB is structural and particleboard is not. Edge swell is less common in plywood due to the small amount of end grain exposure that it has. Both OSB and plywood are used for subfloors, walls and sheathing roofs. In some instances, the builder may not even have an option, as the warranties of other products may be partial to specific sheathing types. However, OSB is known for swelling around the edges when exposed to water. Their manufacturing methods are almost similar but OSB has more structural consistency and is cheaper than plywood.

For roof and floor assemblies, providing dry-in as soon as possible after installation to prevent moisture exposure is recommended even when using “premium” products with long no-sand guarantees. When the panel edges swell and these roofing products are installed, the swell lines often become visually apparent even at ground level. While construction codes regard all materials similarly as "structural panels," the structure of the plywood and the oriented strand board (OSB) is somewhat different. There are some contractors who still prefer plywood over OSB and DRIcore subflooring, however. Applications for Plywood vs. OSB. Pinnacle subflooring has a 50-year limited warranty and a 100 day no-sand guarantee.

The cost to replace a panel due to saturation during construction or prior to installation will be less than it would take to remove and replace an OSB panel later. While both have their benefits and drawbacks, it’s important to ask which one is better for construction—especially with regard to subfloors, walls, and roofs. Plywood veneers are created by cutting a prepared tree to size and then using a lath to peel the tree to form a long sheet. The major distinction between these categories is the actual construction of the sheets.

Additionally, the entire panel may swell due to a change in the moisture content of the panel, and as a result will push against the adjacent panels causing a ridge to emerge. Additionally, vented rain screen systems that promote drying of the wall are recommended in general for exterior walls (and particularly with claddings that prevent or inhibit drying to the exterior). The other motivation for builders to use OSB is money. In this article, we will review the benefits of DRIcore subfloor versus plywood subfloor. Flooring 23/32 CAT PS2-10 Tongue and Groove OSB Subfloor, Application as 4 x 8. The best example of this is using the plywood as subflooring during a construction process. OSB is made of many smaller pieces of hardwood and softwood mixed together in … OSB stands for oriented strand board and is also a type of engineered wood.

Still, if you plan … The cut wafers are then dried to obtain an optimum moisture content that may vary by manufacturer (often as low as 6%). Plywood long ago lost its market leadership to oriented strand board (OSB), which is now the most-used sheathing and subflooring material. Of the two most common subfloor materials, builders often debate which is best: plywood or OSB. Plywood is made of many layers of very thin wood, called plys, pressed together with glue.
