Best Sheathing Material: OSB Plywood vs. Traditional Plywood
Oriented Standard Board or OSB, which is usually known as sterling board, Aspenite or Asply is one of the most used building materials today. This plywood material is a highly engineered wood particle board that is formed by adding adhesives and then compressing layers to a specific orientation. Here, we will review the advantages and disadvantages of using OSB Plywood as a building material compared to the standard plywood material.
Since it was introduced in America, OSB Plywood has been used in building American homes. Individual wood fibers are prepared and are grated in a machine forming small individual pieces of wood that are glued together using a specialized type of adhesive. Formed wood are then pressed together to ensure cohesion, which are then piled up together for finishing. Each of this OSB Plywood is submitted to quality testing. Upon passing quality standards, OSB is then dispatched for delivery.
OSB VS Traditional Sheathing Plywood
OSB Plywood has a high mechanical property making it better suited for building construction. It can be used for flooring and roof decking. It is an amazing alternative to the traditional plywood because of OSB’s fine craftsmanship. Usual American houses are built by a product called “thermoply” which in effect have downside features regarding durability. OSB Plywood and the traditional Plywood are usually the two options for building a family custom home. OSB has been generally a good sheathing choice because of its numerous strands of wood that are glued together making it perfectly flat and stable material. The traditional plywood which is a much more solid wood product is made up of about 4 to 5 ply of wood glued together. Since Plywood is double the cost of OSB material, most American families go for OSB.
The Downside of Using OSB Plywood
However because of separated grated pieces of wood, OSB material is more susceptible to damage in the long term. It is also more permeable than the average plywood, and as the water gets through and soaks up the OSB, it makes it less durable over time.
Custom House Building Recommendation
We give a helpful tip to take advantage of both OSB Plywood and traditional plywood. The two foot section at the bottom of the house starting where the slab stops is usually the most vulnerable to damage overtime. To protect the particular section of the house, it is recommended to use pressure-treated plywood, which pertains to your standard plywood applying it to the two-foot section. This is very termite-resistant and also water resistant. OSB Plywood is then used for the remaining section of the house. Weatherization barrier on top of the wood material is also critical in ensuring durability and added strength. This is a really good method to get the best of both worlds.
