Plywood vs OSB: Which is the Better Subfloor Choice?
They are two of the most popular subfloor choices around. In terms of strength and durability, they give wood planks and concrete a run for their money. They’re also more affordable and readily available.To get more news about film faced plywood, you can visit boosterplywood.com official website.
But between these two materials, which is the better option? Should you use plywood as your subfloor? Or should you go with OSB instead? Let’s find out.Plywood is an engineered wood made from several layers of wood veneers. Each layer is called a ply, hence the material’s name.
To make plywood, adjacent plies are glued together with their grains at a 90-degree angle to each other. This helps to strengthen it and prevent it from shrinking or swelling.
Manufacturers use different kinds of wood depending on what is locally available to them. In Australia, most companies use eucalyptus, fir, pine, ash, beech or birch. Some plywood makers also use mahogany, maple, oak or teak.
You can choose from a variety of plywood types. Each one has unique characteristics that make it more suitable for specific applications.
Because plywood is made from wood veneers, each ply may have knots and other unique peculiarities that create slight variations in its depth and thickness. Thus, plywood’s structure is typically not uniform throughout.OSB, which stands for oriented strand board, is likewise an engineered wood composite. However, it is more similar to particleboard than plywood.
To make OSB, manufacturers use wood from trees such as aspen, southern yellow pine, poplar, or black poplar. They break down the logs to turn them into wood strands, known as flakes. They then dry the strands using high heat.
Once dry, the wood flakes are blended with a mixture of resins and waxes to improve the board’s moisture resistance. Manufacturers then layer the strands on a mat and press them using a machine. They then air out the boards to remove harmful fumes before cutting them to size.
In some cases, OSBs may be modified to serve a particular purpose. Radiant barrier is one such modification that involves adding low emitting aluminum foil to one side for insulation’s sake. Meanwhile, OSBs with tongue-and-groove cuts are designed to interlock to one another for easier attachment.
Just like plywood, OSB comes in several types as well. They represent the board’s different grades, depending on its mechanical performance and resistance to moisture.Many builders use plywood because of its durability and flexibility. Unlike solid wood, plywood boasts of uniform strength along grains regardless of direction. You can use it for different purposes without worrying about its structural integrity.
Plywood also has excellent pliability. Even if you bend it in different ways, it won’t split or break easily. This, along with its lightweight construction, makes it ideal for building various shapes and forms.
Plywood also looks great. Even if it’s engineered wood, ply still retains much of the natural beauty of timber. You can also paint or stain plywood to help improve its visual appeal.
And finally, plywood’s definitive edge over OSB is how it behaves when it gets wet. Plywood swells consistently all throughout when exposed to moisture. But then it dries out quickly and returns to its original dimensions.
