When it comes to building or construction jobs, there are different types of wood products used for a variety of purposes. Two common types of wood products are plywood and sheathing. At first glance, it may seem like these two are the same, but there are significant differences between them that could impact your project’s outcome. In this post, we will explore the key differences between plywood and sheathing.
What is Plywood?
Plywood is an engineered wood product made by gluing together several thin layers or plies of wood veneer. Each ply is layered so that the grain runs perpendicular to the adjacent layer. This cross-grain arrangement makes plywood strong and stable, and it also reduces the risk of warping or twisting. Plywood is used for a variety of applications, from furniture and cabinetry to building construction and flooring.
What is Sheathing?
Sheathing is a type of plywood that is commonly used for exterior wall and roof construction. Unlike regular plywood, which can be made from a variety of wood species, sheathing is typically made from less expensive woods like spruce, pine, or fir. Sheathing is designed to strengthen the structure of a building while also providing a layer of insulation and protection against the elements.
Composition Differences
One of the most significant differences between plywood and sheathing is their composition. Plywood is made of thin layers of wood veneer, which are glued together with strong phenolic adhesives. The arrangement of the layers creates a cross-grain pattern that evenly distributes the panels’ strength and makes them more durable and robust.
In contrast, sheathing is designed to be used as an exterior layer for walls and roofs, so it is typically made of softwood veneers and may have a rough surface texture.
In conclusion, while plywood and sheathing may seem similar at first glance, they have distinct composition differences that make them better suited for specific types of construction projects. Plywood is a versatile and durable wood product that can be used in many applications, while sheathing is designed specifically for exterior wall and roof construction.
By understanding the differences between these two types of wood products, you can make an informed decision about which one is best for your project.
