Theo’s Timber Limited- Birch plywood is a popular choice for a wide range of woodworking projects, but what exactly is it that gives it the edge over other materials? Today we are taking a look at the advantages of using birch Plywood sheets.
Many of the advantages of Birch plywood sheets are a result of the way that it is made. Unlike MDF which is made from small materials, Birch plywood uses veneers that are sandwiched together, usually at right angles to the layer above or below, also known a ‘cross bonded’. This results in a product with a void-free core which gives it greater strength and more resistance to shrinkage.
Strength and Stability
Due to its cross-banded layers of veneer, Birch plywood is much more resistant to warping and bowing than other plywood, especially in thicker sheets. Its void free core also means that screws bite and hold with 100% of their threads leading to better screw holding, this makes it a great choice for long-term use.
Safety
Birch plywood does not have jagged edges and knots, making it a popular choice for making children’s toys and furniture
Solid Joinery
Thanks again to its void free core, joinery such as dovetail joints is easy to do and also looks great. Glue coverage is also easy meaning that anything built in this way should last well.
Appearance
Birch plywood is often chosen for the attractive look of its edges, which can be simply shaped, sanded and finished as they are resulting, not only in an attractive finish but also saving time and materials. It also boasts thicker back and face veneers than usually seen on traditional cabinet grade plywood. There are a number of grades of birch veneer available, the highest grade being B/BB which benefits from a whole piece face with a uniform colour and no knots, streaks or patches. If, however, you wish to apply a decorative veneer to it, this is also not a problem as it accepts paper backed veneer well.
Laser Grade
Birch plywood is available in Lazer Grade, its large sheets that and consistent density makes Birch plywood ideal for cutting on a laser bed.
Environmental Impact
Birch trees are a fast-growing species native to northeastern Europe, the abundance and speed of growth of Birch trees means that it causes minimal devastation or destruction of biodiversity when they are cut down, making Birch plywood a sustainable choice that has little impact on the environment.
